As for sdr, I've a RSP2 and RTL V3 here, as well as a Icom Pro2. The p2 allows for some of the functionality of an sdr minus the need for a noisemaking pc, it has a fft display out to 200KHz and dsp filtering and de/modulation. I can use the p2 for decoding digital sigs with a pc but it doesn't have an iq stream to feed a decoder app with, some decoders are designed to work best with an iq stream rather than an audio feed. I use the p2 to do voice intercept as well as HAM digital modes, and use the sdrs to do decoding work in the utility bands. Also, I've had ten or more vrx up and running with both the RSP and RTL sdrs. I can have two receivers up with the p2 as it has dual watch. To have the same 10 receivers up with the analog rigs I'd need to have 10 analog rigs. It's fun to compare the size of the RTL to the R390A and tell people there's 10 or more of these R390As inside this tiny silver dongle. When the 390A was in use by US int agencies and mil, there'd be entire buildings filled with these things feeding tape recorders or headphones attached to some poor dittybops, sdr changed all of that, save for the morse intercept operators. I know a guy who was stationed in Turkey listening to Russian and Chinese mil cw circuits via the R390A, a lot of history in these rigs and fun to operate. There seems to me much more of an experience operating the analog rigs than the "dry and sterile" sdr, but the sdr has its place assured by the future.
Also on hand are two R390As and a R388, and these are nice for am listening on any freq. I find the audio much more pleasant on the 390As than even the sdrs running the synch am mode. The 390As are also very good at cw and rtty, but I mostly use them for ambc and swbc.
Moral of the story; it's nice to have both on hand.
