Playing with SDR
SDR – Software Defined Radio… Well, I’ve been quite reluctant regarding “going digital” versus “staying analog”, but for a couple of days I’ve been playing with a SDR-IQ from RF-Space, and my verdict is: Yes! My other receivers, a JRC NRD-515, Palstar R30A and Sony ICF-2010 are still very good, but when it comes to the ability to dig up really weak signals from the mud the SDR-IQ stays untouched. Besides that, the SDR-IQ receiver itself isn’t much bigger than a pocket-size digital camera and I need to take the laptop computer with me to Vardø anyway – so this will save a lot of flight-weight for me when it’s time to move up north. Image the carrying weight if I needed to send up the JRC, the R30A and the ICF-2010… Guess that SAS and Wideroe would have one or two things to say about that. Another big pro with the SDR-IQ is the ability to record a bandwith of roughly 190 KHz and everything within this bandwith. Of course, this requires quite a lot of discspace in the computer, but I have that and therefore the decision making regarding this issue is a “no brainer”. Yes, there are SDR-receivers on the market, such as the Perseus and WinRadio Excalibur, allowing recording of even bigger bandwiths – but for now the SDR-IQ is more than enough for me. If I stay nice, maybe Santa Claus will bring me a Perseus or Excalibur for Christmas, hi! By the way, the antenna I’m using here in Biri is a Wellbrook ALA330S which I’m phasing against a 15 meter wire by the means of a MFJ-1026 phasing unit, and the Palstar MW550P MW-preselector when listening on the MW band. The software I use for the SDR-IQ is SDR-Radio.com.
