  • SDR needs more UX

    Spotted a very interesting post from Tobias, DH1TW on his blog ‘Contesting & SDR‘ titled Does SDR really suck?. He wonders out loud if the performance, flexibility and cost of SDR is so excellent, why hasn’t it taken off? What possible barriers might there still be to it assuming a place matching its promise and achievement?…

  • Heathkit Genesis

    Last week at the Waverley Amateur Radio Society monthly meeting there was a fascinating and well-prepared talk from Justin Lavery VK2CU on the history of the Heathkit company. The scene at the front of the clubroom was not unlike this great shot from the website of Fred W1SKU. Only there were more pieces of equipment on display! Justin’s…

  • Arctic DXpedition

    Over the weekend sunspot 1112 erupted and produced a strong solar flare. Now according to space weather sites there’s a 25-35% chance of high latitude auroras on 19-20 October. And right now a group of four Norwegian friends are enjoying their annual DXpedition to Kongsfjord – well and truly in the high latitudes – at 70°43′N 29°21′E at…

  • And they’re racing!

    Interesting thread on the softrock40 email list about how easy it is these days to get a good sense of how well your station and the ionosphere are performing in an almost ‘hands-free’ way. Increasingly modes like WSPR and tools like SDR have enabled us to let the radio do its thing and in a short amount…

  • webSDR

    I’ve spent a little time playing with websdr over the last day or so. This is certainly one way to achieve the subliminal morse background mentioned a couple of posts ago! (Assuming of course the workload is low and the wifi is up!!). You can see even before you ‘tune in’ if a CW signal might be…

  • SDR lists

    Via M1KTA’s blog a pointer to Christophe F4DAN’s exhaustive list of SDR projects. What an amazing resource! It feels like the distillation of many hours of research and study. Really valuable information in here. It was last updated at the end of March. Also available in ‘une version française‘.

  • Windows soundcard software

    Via the new SDR list heard about RV3APM’s page listing a very wide range of ‘Windows software via Soundcard’. It’s a comprehensive, detailed and at the moment very up-to-date listing. Also includes handy information about frequencies for different modes, discussion groups and other background info about soundcard modes. I wonder if there’s a comparable listing of Mac…

  • Waiting for the iPad

    How long will it be before an app is developed and released for the new iPad which will enable you to remotely operate an SDR? The opportunity to use more screen real estate more effectively must be well-suited to such a task. How brilliant would it be to be able link back to your home…
