If you buying a shortwave radio today the best technology is the direct sampling SDR radios. Radios like the Perseus and the Winradio G31DDC
Tuning a knob is really old hat these days if you SWL'er The ability to use a stored frequency list is a huge time save and you can get in much more shortwave listening time by using automated tuning. It also makes checking the bands with the best signal strength very easy. A added bonus is that the S-meters on these SDR radios are very accurate so you can get a very accurate idea of how good propagation is.
The ability to record the spectrum and audio to the PC is a big bonus, especially if you a low band DX'er.
SDR radios are the preferred tool of the modern shortwave listener. The specifications exceed the receiver specifications of ALL current ham radio transceivers.
If you do want the ultimate shortwave radio the only choice is the R&S receivers.http://www.rohde-schwarz.com/en/home_48230.html
Just dont ask the price, they expensive but thats the ultimate receiver available today for governments and the spooks. If you do buy one can you get me one as well?
I would like the one with all options.
I haven't had an HF radio for a long time. I would like to get back into amateur radio, maybe more SWListening. When it comes to just listening, is a base transceiver better at listening or just buy a receiver?
