Dayton 2013

Folks

I’ll be travelling to Dayton on Thursday 16 May and I return on Monday 20 May so orders placed during this time will be processed on Monday 20 May.

We continue to have a good inventory, follow this link about ordering details, or if you’re in a real hurry here’s a direct link straight to the shopping cart.

Many thanks, Howard

    Hi guys,

    Am I correct in assuming the spectrum bandwith is 374 kHz, which is rather narrow for Band II, being used to 500 –> 1600 kHz.

    Best regards,

      The FCD+ bandwidth span is 192kHz as documented in the specs page, and although it is designed for narrow band reception, it also works fine too for Band II wideband FM reception, but that is VHF from around 88MHz to 108MHz depending on your location, not 500 to 1.6MHz.

      Many thanks, Howard

        Hi Howard,

        500 –> 1600 kHz is the bandwith span.
        195 kHz is rather narrow and of course there’s no much of a spectrum to visually analyze then :-(
        Band II is 87.5 till 107.9 over here.
        Is a larger bandwith span something you have in mind for future upgrades?

        Best regards,

          Hello WIH

          It largely depends on your application. For amateur radio use, the span is typically fine as the various sub bands for narrow band use of interest fit into the span quite well, particularly on HF.

          Indeed, the FCD and FCD+ were designed to look for a 2kHz signal in a small 10kHz segment of the 2m satellite sub band. As it turns out, the FCD+ covers almost all of the satellite sub band on 2m in one go.

          Perhaps for your application you’d like to see 1.1MHz of spectrum, but if someone were interested in channel utilization on UHF TV for example you’d want a 400MHz span.

          We designed the FCD and FCD+ to be as compatible as possible with existing software and operating systems, and with that we used a common interface that is limited in bandwidth. Given our primary design criteria, that’s not a problem.

          So it’s horses for courses, if you want a super wide span of tens of MHz and beyond, you probably want to look at a spectrum analyser.

          I have seen discussion over on the Yahoo groups of using the FCD+ with a scanning system that would provide a temporal spectrum usage in much the same way as a spectrum analyser.

          Many thanks, Howard

    Hi Howard,

    I’ve just ordered a ProPlus and I’m really looking forward to testing it on Band II.

    Best regards,

    WIH

    Hi Howard,

    I’ve just received the Pro+ today. I hoped to get it running on an old Dell Latitude D610
    Windows XP 32bit in combination with SDR-radio, but nothing happens at all :-(
    Any pointers?
