SDR For The Masses, Part 5
I was thinking of several portable digital shortwave receivers I have had. And if one had an inexpensive one that was AM only. But dual conversion in scheme and using tuning steps of 1 Khz resolution. Then a qaud detector kit added to that sort of receiver would work nicely next to the PC. Hence PLL control and digital frequency readout. With fancy push buttons and a nice look with the PC that compliments it. At a low cost. If you are familiar with such receivers you know that the conversion scheme and tuning step features I mentioned are available in Grundig as well as Sony and Sangean radios. The SSB versions naturally cost a lot more. You would not need SSB in the receiver when you have it in the software so a $50 to $70 range receiver would do the trick if you just want to scan the HF band bands listening to broadcast. Yet, the PLL controlled receiver could do some amatuer bands work if you are listening at the PC. Here there is a need for a local radio tech and he or she will want to buy the kits and customize the receivers. And there will no doubt be mail order operations for such radios modified with the quad detector kits. C. Crane Company does some modifications now on such radios, adding antenna jacks, etc. I would say that if one goes this route then they will get the idea of SDR to market and into the publics knowledge. And there is the need for publications on SDR and I mean a quarterly magazine and maybe monthly magazine or else a newsletter at least. And then there are the websites that will spring up for radio and kit sales. "Goeth ye forth: maketh many shekels."
