Free worldwide shipping until 30 July!

Folks,

We’re moving the global FUNcube Dongle Headquarters over the next few days to give us a little more room, so because there may be a short delay in dispatch while we set up ourselves, we’re pleased to offer free shipping until Wednesday 30 July, with dispatch resuming at the latest on Thursday 31 July.

For shipping times and ordering, please follow this link. Please make sure you select the “Free Shipping” option during checkout!

We will still use FedEx International Priority for delivery outside the UK, and Royal Mail Special Delivery in the UK, so the shipping times themselves remain the same.

Many thanks, Howard

Yet more FUNcube satellites!

Folks

Although the FUNcube Dongle is capable of receiving many different types of signals, both from terra firma and from space, it was originally designed to receive the FUNcube-1 satellite launched back in November 2013.

What we weren’t expecting when we first embarked on the FUNcube project was that we’d have any more than just the one satellite. Well, we now have three FUNcube satellite payloads in orbit. As well as FUNcube-1, we now have both FUNcube-2 and FUNcube-3 in space.

Although FUNcube-1 is a satellite in its own right, FUNcube-2 hitched a ride on-board the UK Space Agency’s UKube-1 satellite as a payload and was launched on Tuesday (8 July 2014), and already signals have been received. There’s some more news here. The FUNcube-2 payload carries similar capabilities to FUNcube-1, as well as the other payloads carried by UKube.

Here are some videos of UKube’s integration, Soyuz roll-out and launch.

FUNcube-3 is a satellite in its own right, and was launched on 19 June 2014 from Yasny on a DNEPR rocket, and was heard in South Africa ten minutes after deployment and has a BPSK telemetry downlink as well as a linear transponder. There’s more information here.

Many thanks, Howard

Pro+ and Pro differences

Folks

A quick note to let you know that you should make sure when downloading documentation and software that you are using the correct versions for whichever FUNcube Dongle you have! Aside from different front markings, you can identify which one you have from the serial number that’s marked on the back. The original FUNcube Dongle Pro’s (FCDP) have serial numbers less than 10,000. Serial numbers 10,000 and above are the FUNcube Dongle Pro Plus (FCDPP).

Although the two FCD versions look similar from the outside, inside the hardware’s almost completely different, and using the wrong software and/or documentation with each device will inevitably be frustrating! There were many improvements made when we designed the FCDPP, most notable being coverage down to LF, auto-switched discrete front-end pre-selection filters including very selective SAW filters for 2m and 70cm, doubling of spectrum bandwidth, and use of a very stable TCXO reference oscillator. The component count is 250% greater as a result, but we still managed to squeeze it all in to the USB dongle enclosure – just!

You’ll notice a couple of menus at the top of the page, one is “The New FUNcube Dongle Pro+” and the other is “The Original FUNcube Dongle“, so you should choose the one appropriate to your FCD.

In other news, we’ve just begun started receiving yet another batch of FUNcube Dongle Pro Plus units from the manufacturers, so we’ve plenty of stock and you can order directly by following this link.

Firmware updating on the FUNcube Dongle Pro+

Folks,

As you may know, there are two FUNcube Dongle models out there, the original FUNcube Dongle Pro (aka FCDP, serial numbers below 10000, firmware v18x where x is a release letter, with v18j the most recent) and the newer FUNcube Dongle Pro+ (aka FCDPP, serial numbers 10000 and above, firmware v20.xx, with v20.03 the most recent).

FCDPPs shipped since about November 2012 with serial numbers 10250 or so and above already have the latest 20.03 firmware shipped with them, so there is no need to perform an update. (The only other public version in the very early FCDPP units were inadvertently sent out with FCC cellular blocked frequency ranges, other than that they functioned perfectly well).

Although the names of the two FUNcube Dongle models are similar, they’re almost entirely different hardware designs, and the firmware designed for an FCDP won’t work in a FCDPP, nor the other way around.

When I wrote the bootloaders for the FCDP and FCDPP, I didn’t include a check to ensure the right firmware files were for the correct FCD. Next time I will! There should be no harm if you inadvertently upload the wrong firmware, but the unit should simply remain in bootloader mode until a valid firmware image is uploaded. Both the FCDP and FCDPP include several safety mechanisms both in software and hardware to perform a sanity check in case the firmware’s wrong, and if it makes no sense the device will sit in bootloader mode to prevent “bricking” the device.

So in short if you’ve recently purchased an FCDPP, you shouldn’t have any need to update the firmware.

Many thanks, Howard

FUNcube Dongle and SMA connectors (and the Dashboard)

Folks,

I wrote a note about the SMA connectors that the FUNcube Dongle uses for its antenna connection some time ago, but I think it’s probably worth reiterating.

All FUNcube Dongles have conventional SMA female connectors, so your antenna lead needs to have a standard SMA male connector to mate with it. Standard SMA connectors have been around for decades, and are fairly ubiquitous these days in commercial RF equipment at VHF and above, but are perfectly well suited down to LF too, especially if the device is tiny (like the FUNcube Dongle!)

The problem is that as well as “standard” SMA connectors, there are also RP or Reverse Polarity SMA connectors available. The RP connectors were developed more recently as an attempt to have a physical way to make it difficult to put high gain antennas on WiFi equipment.


For the FUNcube Dongle, the SMA on the left is GOOD, but the RP-SMA on the right is BAD! (Picture linked from OscarLiang.net)

To confuse things, there is nothing physically to stop you plugging an RP SMA male into a standard SMA female, such as that on your FUNcube Dongle. You won’t break anything, but it won’t work either as there is no prong on the RP SMA male to mate with the standard SMA female on the FUNcube Dongle. This will be reflected in the apparent insensitivity of the FUNcube Dongle, which is hardly surprising either, it’s just like having a break inside you antenna cable!

So, in short, do not use RP-SMA connectors on a FUNcube Dongle, they won’t work. The correct SMA connector should have a centre pin.

Onto another subject entirely, we had a very useful meeting of the FUNcube team over the weekend, and we’ve been making some further improvements to the Dashboard software which will be released soon, increasing decoding sensitivity by about 6dB when used with the FUNcube Dongle.

Many thanks, Howard

February 2014 update

Folks,

The New Year has been busy, we’ve had some large commercial orders as well as plenty of personal customers, many I am sure eager to try their hand at receiving the recently launched FUNcube satellite, as well as many other signals: remember the FUNcube Dongle Pro Plus is capable of receiving narrowband signals of any sort with the appropriate software from LF to 2GHz (full specifications here).

The inventory level remains good, you can order by following this link.

You don’t need big antennas to receive the FUNcube satellite, I’ve had success receiving the satellite with a simple rubber duck antenna. At home, I’m currently using an end-fed half wave mounted on the end of an 8m telescopic fibreglass fishing pole (with the ubiquitous duck tape, of course!) with good results, even with 20m of RG58 cable loss.

Using a half wave antenna means there’s no need for a ground plane. Similar results can be achieved with a 1/4 or 5/8 wave, but it will need a ground plane of some sort for optimum results. Of course, a simple dipole tuned for 145MHz will work. Whether you use horizontal or vertical polarisation is up to you: the satellite is rotating so inevitably you’ll experience some fades if you use linear polarised antennas such as those described.

What I have found is that having the antenna out in clear space helps a lot: these days there’s so much RF noise from all sorts of sources that having the antenna mounted outside, away from your computer equipment and home network (even plasma TVs and other domestic electronics can emit plenty of RF noise) is very beneficial in receiving the weaker signals from space. As a rule of thumb, if you plug in the antenna and see an increase of more than about 10dB of noise floor, consider moving you antenna. It’s just like astronomers being affected by light pollution, but in the radio spectrum.

Many thanks, Howard

FUNcube Dongle Pro+ inventory

Folks,

Over the past couple of weeks the demand for the FCD Pro+ has increased fairly dramatically, and in underestimating that demand I’m afraid we’re out of stock for the next week or two while we get the next batch finished.

Please feel free to register your interest here, and I’ll email you as soon as we have stock. I am still due a few more from the last batch from my board assembler over the next few days, so I’ll release these as they become available to those on the waiting list in order.

We don’t accept payment unless we have real stock on this website. However, retailers may not have the same policy, so I would suggest that you confirm stock level with your reseller to avoid disappointment.

Thank you for your patience!

Many thanks, Howard
