Re: [IRCA] Testing New SDR software

[Russ Edmunds <wb2bjh@xxxxxxxxx>]

SDR's are lower in cost ? I suppose that might be true if you could find a high end receiver new, but the prices I see for any of the newer generation SDR's are quite high. Well north of $1000 would be beyond what I'd want to spend for a hobby receiver whether SDR or traditional, and I'm certain a lot of other DX'ers would view it similarly.

As more and more manufacturers stop making standard receivers, perhaps the demand for SDR's will dictate some price moderation.
