Qt cross platform source code (original by your truly, a bit flaky)
Much better Qt cross platform frequency control app with source code by Alexandru Csete

Notes:

The fully featured front end makes use of some functionality that exposes some NDA device functionality via a back door API that I used in the early days, so there’s no source available I’m afraid. That functionality will be available in the documented API firmware that I’m working on as we speak.

Tip: with the fully featured front end, pressing the “Defaults” button is almost always the right thing to do when you first plug in the FCD or launch the app. It resets a bunch of gain parameters to something sensible. The basic front end only allows frequency changing.

Known ‘features’ of the Qt host code (this has been written from scratch and these bugs not apply to the earlier Windows-only code)…

o Under Windows, when switching back from bootloader to normal “application” SDR mode, the FCD seems to stay in bootloader mode. Workaround: remove FCD and plug back in again a few seconds later.

o Under OS X and Linux, Switch to bootloader crashes the app. Workaround: Restart the application without removing the FCD. The FCD should now be in bootloader mode.

o Under OS X and Linux, Switch to application crashes the app, and FCD remains in bootloader mode. Workaround: Kill app, remove and reinsert FCD after a few sconds, then restart the application. The FCD should now be in application mode.

Using the bootloader

1. From the fully featured front end, put the dongle into Bootloader mode by pressing the “Reset to bootloader” button.

2. The Frequency Control app will no longer be able to send messages to the dongle once it is in bootloader mode. (Don’t panic, as long as you haven’t erased the device or written a bad binary image [aka a .bin file], if you unplug and plug it back in, it’ll go back to normal SDR mode. If you erased it or wrote a bad image to the device, it will spend its life in bootloader mode until a correct image is written. I spent an awful lot of time trying to make sure it’s very difficult to “brick” the FCD, in fact I haven’t managed to do it yet in its current version).

3. Run the FCHIDBL.exe program. It should show something like this:

HIDOpen of Vid_04d8&Pid_FB56 returns 1
USB VID/PID found.
HIDQuery returns 1
Query message: FCDBL
FCD in bootloader mode
Byte address range: 0x002A00 - 0x007E00
PC address range: 0x001C00 - 0x005400
Device ID address set
Device ID read, DEVID=0x4203, DEVREV=0x0200

4. Open the .bin firmware image file with the “Open file” button.

5. Press the “Write firmware” button. This takes about ten seconds or so. (When in bootloader mode, the soundcard interface says “BOOTLOADER” in 24WPM CW if you run your SDR program)

6. Press the “Reset to app” button and the dongle will now be back in SDR mode. Note that the bootloader app will show the following after “Reset to app” is pressed:

HIDOpen of Vid_04d8&Pid_FB56 returns 1
USB VID/PID found.
HIDQuery returns 0
Error, query device failed

This is normal as the bootloader has realilsed the FCD’s no longer in bootloader mode.

    Hi Howard,
    Congratulations on your recent success and the amazing response to the sell out of the
    Funcube Dongle. Apart from your very valuable contribution ( not only money but
    time and effort ) to making our hobby an asset also to education – you have made history ! – Fantastic.
    Unfortunately due major problems with my Paypal account being used to gain access
    and withdraw money from my bank account , I was advised to stop any transactions
    whilst investigation are taking place.
    Not sure even if things had been OK whether I would have been quick enough on the draw at my age to beat the rapid response on the day of the sale anyway.
    I have been invited once again to put on a table on behalf of Amsat at the Swansea
    Amateur Radio Society here in Wales during February.
    It would be an apportunity that I would not like to miss to show and perhaps demonstrate the Funcube Dongle along with details of the Funcube satellite.
    Also talking to members of ISSET ( International Space Educational Trust ) in response to the request for support needed fro the project etc.
    Congratulations.
    Happy New.

    Hello, is already someone busy with designing a DLL to use with Winrad or WRplus (to tune the FCD LO without having to use the “Windows full-on front end” ?

    Last week I have seen a nice DLL for the PM-SDR (see http://www.iw3aut.altervista.org/), it also had some preset buttons for several Broadcast & HAM bands, including frequency steps (e.g. 9 KHz for AM broadcast), something like this should be wonderful for the FCD.

    Sorry I’ am not a programmer my self…

    Hello FunCube Dongle fans!

    Did someone used the software “SDR-Radio” from Simon Brown successfully with the FunCube Dongle?
    Looking forward to every hint.

    • Rob says:

      Hi Alexander
      Yes and works very well, audio quality is great, at the moment we don’t have frequency change of the FUNcube dongle via Simon’s software ,but works great via the sound card input and the front end software.
      Rob

    • Frank PH2M says:

      Hello Alexander,

      With use of the App. FUNcube Dongle Frequency Control it works, but if you want to tune like with WRplus using the ExtIO_FCD_G0MJW.dll this is not working, sadly SDR-RADIO doesn’t recognize this DLL file.
      Sadly Simon doesn’t have a FCD and is not busy making SDR-RADIO compatible with a DLL file like this…

    Many thanks for your feedback.

    Hi.
    The link to the “Windows fully functional front end with source” is Broken.
    I get a 404 page not found error
    After playing around for a bit I managed to get FCHid004.zip
    Here is a link that should work for everyone.
    http://www.funcubedongle.com/MyImages/FCHID004.zip
    I must admit I did find it strange that the error was caused by not having the filename all in uppercase. (Must be something to do with the webserver)
    Hopefully this helps…

    P.S. Once this error is fixed please feel free to remove this post.

    • Rob Thompson says:

      Just to clarify:
      I was talking about the
      “Windows fully functional front end with source (needs firmware 18d or above)”
      Also has anyone got any ideas on what settings to use when living in an RF Noisy location. (I have experimented with settings but it only gets worse)
      I have found using a HS-790 Duplexer as a bandpass filter for UHF helps a bit.
      Also have found using a SSE RF Notch Filter to block out pagers on 153 MHz helps a bit on VHF.
      But I am not getting half the result I can get using normal VHF & UHF Radios.
      I had hoped to make some good youtube videos to show off my FCD. But the only one i’v made so far is using it to listen to my local repeater. (What i forgot to mention in the video text that the dongle was on a Watson W30 Colinea while I was comparing it to a cheapy handheld on it’s own antenna)
      My youtube vid is hear: http://www.youtube.com/watch?v=gTeowGtwOtE
      The FCD demo is in the last 2 mins of this vid. And I did slip up because the other SDR i use requires I&Q be swapped.

      • Rob says:

        Ok make sure the level on the FUNcube dongle is set to 1 in recording devices.
        Set the mixer gain to 4dB, If your level of noise is very high, you may have to change the antenna to a beam.

        • Rob Thompson says:

          Thanks for the reply Rob.
          You said set recorder level to 1 But.
          I’m using Windows XP and there is no slider available for the USB Audio Device so it’s already preset to what ever level the dongle gets when 1st plugged in.
          Also I don’t have any OS beyond XP and reading other posts I get the feeling Howard don’t want that adjusting.

          I did change the Mixer Gain to 4dB and that did lower the raised noise level seen +/- 15k of the Lo Frequency but has now made the local repeater inaudible and barley visible on the waterfall. So it got worse instead of an intermittent dropout I am now get nothing. :-(

          As for using a beam I can’t aim toward my local repeater without aiming directly at the noise. I will give it a try later and compare the FCD using a beam to my Alinco DR-605 using a dipole, But I suspect the Alinco will provide a better result. (Even if I swap the antennas)
          I will post my results later.

          Just a reminder (As this is the Downloads section)
          The Windows Front End (HID004) for Firmware 18d(pre) can successfully downloaded using this link:
          http://www.funcubedongle.com/MyImages/FCHID004.zip

            Hi.
            I’m sorry to say my results are NOT GOOD.

            1) Using FCD & a beam has NOT allot of benefit. (Some but very little)
            2) Using Alinco & a beam has lots of benefit.
            3) FCD can NOT pick up AO-51 using a beam.
            (also tried the dipole just in case)
            4) Alinco can pick up AO-51 using a dipole.

            I’m confused now, I’m not sure if this is local RF Overloading it or a problem with sensitivity.
            I will proceed with more testing,

            If you want to see my satellite beams click hear:

            and

            12 Ele J-Beam for UHF
            12 Ele ZL-Special for VHF
            Tripod is balanced with a bit of friction so we can let go of it.
            360* Azimuth (can spin about 3 turns) by 180* Elevation (No need to rotate 180* and loose polarization when sat passes over head)
            Tripod is a heavy duty light stand from Maplins (Cost APX ₤20.)

            Next tests will be with some filters & a preamp on loan.
            Anyone got any other ideas?

            Hello Rob.

            How far does the noise floor rise when you plug in the antenna?

            Howard

  13. Rob Thompson says:

    Hi Howard,
    Thanks for your reply.
    Without an antenna I get a -100db noise floor on 145.0 MHz and 435.0 MHz
    with an antenna I get a -95db noise floor on 145.0 MHz and -85db on 435.0 MHz

    But I’v noticed two things and this could be the reason.
    1) If a apply a slight twist to the SMA the noise floor dances around and sometimes returns to -100 db with the antenna plugged in. (Returns to -100db but with carriers that are not there without the antenna)

    2) I believe i’m getting RF noise from the PC it’s self, On certain 2 meter frequencies there is a very wide noise that I can shift by placing my fist around the USB extension lead. (I use a floppy USB extension lead to release any tension on the dongle due to the stiff coaxes I have)
    I have also checked the VSWR using that same antenna connector while wiggling it and found no problem. (Just in case it was the BNC I fitted)

    Does it sound like:
    1) I have a hairline crack near the SMA connector?
    2) Need to dig out my other PC hoping it has less noise? (BTW I’ll try this later today)

    Thanks in advance.
    De. Rob 2E0RPT

    • admin says:

      A 5dB increase in noise floor with the antenna plugged in on 2m is good and what I would hope for. However if you are seeing intermittent connectivity issues then that is indicative of a possible failure in the AC coupling capacitor in the HPF that I have seen occur in some units particularly if significant physical stress has been applied at the SMA end. As part of checkout, this is specifically tested for with stress applied. I am happy to check it out for you. The two units I have had returned with this fault have been fixed and back out the door the same day, one by post and one by personal caller which I fixed there and then – if you want a tour of the kitchen lab and a fix on the spot, let me know ahead though in case I’m out.

        2) Did you fix the problem?
        3) Have you posted it back yet?
        4) If you posted it back on Wednesday or Thursday can you tell me the tracking number?
        It hasn’t turned up yet and might still turn up on Monday.
        But I can’t ignore the fact the lazy posty leaves failed delivery notices in the common hall of my block of flats and allot of mail goes missing round hear.

          • Rob Thompson says:

            I’v still got problems receiving everything. :-(

            My Noise floor keeps changing like local transmitters are de-sensing it.
            (Sounds like too much gain)

            And I can’t pick up ANY satellites on FCD even when the packet from ISS is very clear on the other radios.
            (Sounds like not enough gain)

            A 5&9 signal on the Alinco = a weak signal on the FCD using the same antenna (Not at the same time LOL)

            Did also try FCD using Arrow antenna on the downs away from town & everything electrical (Except Laptop) but didn’t hear ANY satellites.

            So what should I do now?
            Do I go buy preamps or filters?

          • SM3KYH says:

            I would go for bandpass filters

          • admin says:

            Hello Rob

            Sorry for the delay in replying, it’s been a little busy over the weekend with the sale: I have to be careful about my internet immersion during these times otherwise I’d never finish the distribution in time for the next post.

            If you’re seeing more than about a 5dB increse in the noise floor when you plug in an antenna, then you’re suffering desense.

            In this case I suggest either a low insertion loss filter or a preamp with integrated filter.

            As you probably know we’re investigating some reasonably priced options. http://www.funcubedongle.com/?p=456

            WOW WHAT A DIFFERENCE
            I was amazed how well it worked.
            Only problem was the laptop I was using did not want to record in WRPlus without stuttering the sound. (Believe laptop needs tighter rubber band or something LOL)

            I will try this again sometime with external PSU for laptop (so it runs faster) and I can then record the band and playback later while recording my screen for a YouTube video.

    • admin says:

      Hello Nacho

      It depends what you’re trying to do. The later firmware versions open up the FCD’s functionality for third parties to develop code beyond simple LO frequency changes. Typically I would expect third party developers to state “requires version xxx of firmware”.

      The intention is alway to maintain backwards compatibility, so 18f should support all the functionality of previous versions. Later versions also have bug fixes as well as API enhancements.

      Hi Tony

      This is resolved if you have Apple’s Xcode toolchain installed.

      When things settle down I’ll have chance to package this up, unless of course anyone else is offering! I’m not a Mac guy, and until a few weeks ago it had been 20 odd years since I’d last programmed for a Mac, so there’s rather a lot to take on board!

      Howard

  20. tony G3OVH says:

    Hi Howard
    Thanks for the quick reply. I “appear” to have the xcode toolchain installed from when I upgraded to Snow Leopard, but I havn’t actually used it – it certainly appears when I click on an Xcode project, and indeed whenever I open any source code, so I don’t know whether some project building in Xcode has to take place to get QTCreator to have the correct environment. As you can guess I am a bit of a newbie with these huge development suites. BTW, I was somewhat taken aback by the enormous disc space QTC…. needed – 2.2GB.

    Re Xcode, QTCreator etc

    ps is it better to post on the FCD Yahoo group or here for such dialogue?

    • admin says:

      Hi Tony,

      There’s also and FCD developer group that Rob set up.

      Regarding Xcode, for the vrigin Mac I purchased about three weeks ago, which had Snow Leopard on it, I installed QT Creator, and received the exact same error as you regaring the make utility. So I installed Xcode from the Apple dev site, and that fixed it immediately.

      Howard

  22. tony G3OVH says:

    Hi Howard
    I registered as a Mac developer and downloaded the Xcode 3.2.2 upgrade. That cracked it. Now I can get probably as far as you got with a bunch of errors/warnings needing fixing, and also got the same application window – none of the buttons do anything yet – but on the other hand I havn’t yet got a FCD to talk to, so perhaps that’s why they are greyed out.
    More midnight oil to burn I guess.

    Hello all…
    I have just received my FCD (170 – it’s been around with my son for a month or so awaiting handover to me… birthday and all that…) and it has been known to work on a laptop not far from me. I have no idea how many PC keystrokes it took him to get itgoing, but eventually it did and we were delighted with initial results.
    Now – I try to install SpectraVue on the shack PC (WinXP). It wont run, and displays”SpectraVue MFC Application has encountered a problem and needs to close. We are sorry for the inconvenience.” Son has departed.
    So – awaiting reply from Moe about the possibility it might be unhappy about running in H:\ rather than C:\.
    Now – considering using WRPlus. However – how does one establish which firmware version is in my FCD? Must be 18c. Reading the Firmware Update Guide I see no reference to the actual current version nor the version which is about to be loaded.
    Downloaded Bootloader, double-clicked it but FCHDIDBL.exe seems to be buried in folder then a subfolder, running it needs zipped files within the folder unzipping, and is generally unfriendly to a non-PC guru. Advice please…

    • admin says:

      Hello Terry

      Thanks for your note. The firmware update guide was written before we introduced firmware numbering. You can determine the version by looking at the result of the “Query message” line (line 4) in the FCHIDBL.exe file while the FCD is in _application_ mode.

      If on the fourth line it says “Error, query device failed” then it is either 18b or 18c. To determine whether it is 18b or 18c, imediately after insertion, start Spectravue (if you can!) andthen use the _original_ Full function front end’s Default button. If there is no difference to the noise floor then it’s 18c. If it drops by about 15 to 20dB then it’s 18b.

      Later versions make it easier. These are the other possible strings for that fourth line in application mode:

      “Query message: FCDAPP 18.04″ version 18d
      “Query message: FCDAPP 18.05″ version 18e
      “Query message: FCDAPP 18.06″ version 18f

      I am not sure why you “need zipped files within the folder unzipping”? The firmware is distributed unzipped, you just need to open the file in the appropriate folder where you downloaded it.

      Howard

  24. Please Howard,
    May you add a date of the release to all the files , in the download page?
    Just the same as is for the WRPlus download.
    It would make it easier for the end user, I guess.

  25. Hi Howard

    I am trying to develop an FCD instrument for my astronomical software ‘Starbase’, written in Java, with the help of Phil Ashby’s Java wrapper code. I was wondering if there is an ‘approved’ logo or icon for the FCD that I may use?

    Starbase is open source (GPL) distributed by the UK Radio Astronomy Association (UKRAA) , in conjunction with the British Astronomical Association. We are making an integrated observatory for radio and optical observations, using a variety of hardware. The FCD offers an opportunity to make e.g. a spectrometer for radio observations of the Sun, accessible to amateurs and schools, and we are keen to collaborate if we can.

      Hello Laurence

      The FCD is strongly connected to the FUNcube satellite and so it borrows its “branding” from AMSAT-UK’s FUNcube satellite project. Happy to help here if I can, you might find it easier via email though.

    Hello,
    I just received my FCD yesterday, works fine but I think it is very deaf. I cannot receive even the local QSO’s without the RX preamp on 2m and on 70cm. Is there a special configuration to increase sensitivity? I do not expect a super sensible rx but even local repeters or qso’s should be possible to receive. I have updated the firmware to v18f and tried to play with the parameters on the FCHid control software. I see an improvemens in increasing the S/N ratio by reducing theLNA gain to 0dB. Can I do some thing elese to improve the rx performance?
    Further, I would like to know if someone has experience with FCD working with wsjt or Linrad?

    • admin says:

      Hello

      I suspect that you may be seeing some receiver blocking from some other signals. Typically people have been adding front end filtering to improve this.

      The FCD itself is pretty sensitive: I personally test every one for 12dB SINAD at 0.15uV prior to dispatch. However the front end filtering on VHF in particular can block.

      In addition, you may have a noisy PC: I am aware that filtering on some USB hosts is not the best. I strobgly suggest using a USB extension cable on the FCD to separate it from the PC particularly if you are encountering the situation you appear to have.

      Many thanks, Howard

      • SDRsharp says:

        I have experienced the same problem here. I live less than 2km away from tens of multi kilowatt broadcast transmitters (FM/TV/DVB.) Reducing the gain helped a lot. A tracking filter would have been ideal, but I imagine how difficult it is to include such a functionality in a tiny USB dongle.
        Otherwise, everything is working OK.

    • EA3MS says:

      Howard,
      I was checking again, I have always been using a shielded USB cable extension for the FCD. I see that the trick is to set the initial 20dB for the LNA to a lower value (e.g. 0dB) and I reduce the mixing gain at the first mixer to 4dB instead of 12dB. I was comparing the FCD to my FT 847 and preamp I can hear better low signals on the FCD.

  33. Aaron says:

    Hi Howard,

    I received my FUNCube Dongle today and am looking forward to getting a chance to write some code for it.

    Quick question: Is there a HID command (i.e. the second byte that I write to the HID device write handle) to retrieve the current firmware version so I can determine which revision is installed on the device?

    • admin says:

      Hello Aaron

      First you need to identify if it’s there at all using the basic USB primitives.

      Then you can send a “query” hid command to identify if it’s in bootloader mode or application mode (responds with a TRUE status byte followed by a string, [FCDBL], or [FCDAPP+version and board info]). The exception to this is if you’re in app mode and you have the base factory 18b: in this case, it doesn’t understand the “query” command so you get a FALSE status when you send a “query” command and it’s in app mode.

      So you need to do a little probing I’m afraid to determine this programmatically.

      You can also tell interactively by using the FCHIDBL program and a bit of detective work. Run the FCHIDBL program up and then insert the dongle. The FCHIDBL program automatically detects the FCD insertion and sends a “query” hid command, and displays the “query” result automatically. If it’s the base 18b, it will show “Error, query device failed”. Any other verision will show “Query message: FCDAPP xx.xx Brd y.y etc….”

      There is no harm in upgrading or downgrading to and from different firmware versions. Just keep in mind that when you do the firmware updates that no other apps are FCD running, as this interferes with flash uploading, and as often as not it will get stuck in the bootloader, which is the default “panic state” of the FCD – for good reason, otherwise it might end up bricked! There’s no harm done, if you end up in this position, just upload the firmware again but without any other apps running.

      Many thanks, Howard

    Are the dongles all functionally tested before shipping? I just received mine and updated firmware to 18i. Using Qthid and iSpectrum on Mac. Scanning the bands, I get nothing but noise or the occasional birdies… Nothing like the videos other users have posted on youtube. Just using a short wire as an antenna, but I’d expect to at least get some signal for the strong local FM radio stations. I’ve maxed out the all gains in Qthid. Reading other’s comments, I tried reducing the LNA and other gains. No joy. Possibly a bad dongle??

    • admin says:

      Hello BK

      Firstly I am sorry that you are having difficulties with your FCD.

      I personally test _every_ FCD end to end, and that includes RF sensitivity testing, just prior to shipping.

      Can you let me know what happens when you plug in and remove the antenna?

      Are you using a USB extension lead, or is it plugged straight into your Mac?

      Feel free to email me some print screens to my Paypal email account.

    Hello ,
    I recently got the Funcube , it seems to work fine , the background noise with 50 Ohms at the input is a little high -85 dB with spectraview, not about -100 dB as mentioned in the manual.
    As I had planed to use it at 1240 to 1250 MHz as the if reciever for my 8.4 GHz spacecraft tracking station, I am a little dissapointed that just in that frequency range, 1095….1265 MHz it is not usable.I read in the faq that there is a locking problem .
    Is there a chance that this will be fixed in the near future ?

    best regards Wolfgang , Dj3qd

    • admin says:

      Hello Wolfgang.

      Regarding the -85dB, this can be a little misleading as this is a figure designed for relative measurements rather than being an absolute measurement. It is also of course dependent on what the gain settings are set to.

      I am afraid there is a limitation in the PLL, VCO and divider chain of the tuner chip that we use. This is not specifically documented by the chip manufacturer, but when we started to test preproduction units out, we dicovered the gap that we documented in the FAQ. I’m afraid that with the current device there isn’t a way to circumvent this. Can you adjust your LO to compensate?

      Many thanks, Howard

    Hi Howard,

    is there anywhere a documentation about the several paramaters which shown in the FCD control panel? I didn’t find anything. My 2nd question is about the byte stream which will be send to the FCD for frequency setting. I assume that within this control string not just the frequency is set, but also the FCD filter, preamp, phamtom volatge … will be set. Is there a documentation about the field description to be used?

    best regards

    • admin says:

      Hello Bernhard

      Thank you for your note.

      The parameters directly control the available settings on the tuner chip itself. I strongly recommend that you take a look at the source code made available such as http://www.funcubedongle.com/MyImages/FCHID008.zip as that has all the code used to chat to the FCD using the USB HID interface. There is a header file in there, FCHidCmd.h, that describes the various command codes.

      In general, each of the settings are controlled with a separate HID command.

      There’s also a post here that describes the HID interface: http://www.funcubedongle.com/?p=107

    Hi. Received the FCD today. basic front end can set freq under windows, Spectraview can receive radio, so FCD is working 100%.

    Under both windows and the Mac, the precompiled Qt “fully featured” front end fails to find the FCD — the UI is disabled and there is a red message “no FCD detected”.

    Given this failure, I downloaded the source code, compiled it in Qt, fixed the warnings in the code (unused variables in function calls, harmless but annoying and very bad practice), and get the same results.

    Before I go digging into the source to try and figure it out, I should point out that the FCD is plugged into a powered hub — where, as I say, it works fine with the simple front end and Spectraview. Does anyone know if the Qt code handles other than the primary ports on a computer?

    Ref.: FCD Pro #5939, Firmware 18j

    Hello Howard.

    Sorry, but I need help. I can not do my FCD to work. The FCHid I can run successfully, the FCD is detected, but the same does not happen with SpectraVue (installed and reinstalled). In the lower left corner of the screen is labeled “USB Not Connected”. It is not possible to start the setup. I have installed on my PC (Win Vista) SDR – Radio V 1.4, which also does not detect the FCD: the screen and the sound is the same with or without the device plugged. My Mac (OSX V 10.7.4) also ignored the FCD plugged – no reaction. What to do?
    73′s, Clinton, pt2ar

    • admin says:

      Hello Clinton.

      You must set the Spectravue InputDevice to SoundCard, then go to the SoundCard In Setup and configure that. Spectravue does not directly understand the USB protocol used by the FCD. That is why you need the FCHid program.

      I can recommend Mark Culcross’s excellent document here on setting up the FCD http://www.hamradio.co.uk/userfiles/file/funcube_setup.pdf, although note that we are now up to firmware 18j.

      Once the firmware is updated, you can use software like SDRSharp and SDR Radio to directly control the the FCD in an integrated manner. For the Mac, I can recommend SDRDx http://fyngyrz.com/ which directly supports the FCD too (you need to press the “FCD” button).

  52. Peter says:

    I am somewhat puzzled by the FCD+ I purchased last month.
    I’ve been running it with SDR# and find it flatly insensitive, what sort of results should I expect on say, the 30m band, the FM band(87.5-108MHz), 2m and 70cms.
    I ask for some quick practical checks as I want to divide up my experiences to see if it SDR# or the FCD+ that is the item puling down results.
    I will try and arrange for MDS measurements through a friend, and I’ll also be trying out other programs like HDSDR and KGKSDR.
    Regarding SDR# (the stable version)- It took me a while to latch on to the ‘reversed’ gain setting needed in SDR#.
    Are there any other unexpected quirks there?

    • admin says:

      Hi Peter.

      On HF, the FCD+ is about the same as an SDR-IQ, that’s what I used as a benchmark when developing the FCD+. A quick measurement is to get around 12dB SINAD for NBFM for -108dBm in on HF. I use the SINAD test as it’s really quick to set up and provides a comparative measurement for sensitivity purposes.

      For 2m and 70cm, the units are measured for 12dB SINAD for NBFM at -123.4 (0.15uV). Broadcast band should be about the same.

      If you really are getting insensitivity, please check that you are not using a WiFi reverse polarity (or RP) SMA connector: you need a standard SMA connector for the FCD and FCD+.

      Regarding the “reverse gain” setting, I think that you are referring to the “Swap IQ” setting: this is covered in the manual. The FCD and FCD+ use the same “standard” set by Spectravue, but other software chooses to operate in the reverse way. http://www.funcubedongle.com/MyImages/FCD2ManualV4.pdf

  53. Gary Vander Haagen says:

    Received the Pro+ about two weeks ago. Works nice. Thanks. On the PC I get a noise floor of about -80 dbm with a center and +- 75 KHz peaks either side at about -70 dbm. Is that normal?

    Gary

    • admin says:

      Hi Gary

      There are two minor peaks out towards the span edges, one either side, that I believe are caused by the ADC’s internal LDO regulators. Interestingly, they also appear on the manufacturer’s data sheet.

      The peak in the middle is due to DC offset and phase noise. SDR# should do a pretty good job at getting rid of the DC offset but phase noise by its very nature is not predictable so you’re left with a peak at the centre. This is a product of the analogue quadrature mixing stage and LO, and usually I recommend demodulating off centre because of this: there’s a note about this in the manual.

      Many thanks, Howard

      Sorry it looks like I misunderstood your question. What OS are you using? If it’s Vista/W7/W8, check the levels setting for the FCD+ recording device in the Sound control Panel applet.

      Also what software are you using? The dB levels are all relative, but I agree, about -95 to -100dB or so is a nice starting point.

      If you are seeing the spurs, as these are very low level, then I am sure that it is a software-side level setting thing.

      Many thanks, Howard

    Howard,

    Thanks. Using w7 with a resetting of the recording level the spurs are just about gone and the noise floor runs -105 dbm or so. The overall sensitivity is also better. Thanks much.

      Hello Tore

      Yes the FUNcube ProPlus(+) does do HF. The original FUNcube Dongle Pro does not.

      Many thanks, Howard
