Bryce, I actually use a Softrock Ensemble II SDR for shortwave. It has the added advantage of being able to precisely lock on to the WWV stations and check the accuracy of my frequency counter. It also is just truly amazing to use the SDR software such as SDR-Radio or HD-SDR. You can calibrate it down to the sub Hz level and the sensitivity is really good. It can be build for LF or HF ranges. I could go on and on about the coolness of the device.
Just food for thought,
Jeff

I used an Sa612 mixer chip feeding a LM3089 into a 386 audio amp chip. That setup is cheap and can be configured to give am and fm but no ssb.
The best solution is to find a used AOR 8000 wide range handheld receiver. That demods everything from 100khz to 1950mhz. They were 500bucks new but I just saw a working one sell on ebay for 50 bucks or so.
Another solution is to pick up a Kaito1103 SW radio. Very cheap radio that works well. Degen makes its twin. They handle Am/Fm/Ssb using the BFO on the radio.
I have to confess after adding the demodulator to my HP8558B, I never use it. By the time you zero the span, center the signal, and fool with the demodulator, it becomes work.
I find the easiest solution is to buy a wide range receiver (Icom r8500 or AOR 8000 etc.) and connect a display unit to it. Then as you tune the radio, you see the signals at the same time.
Have fun, Ken

I am looking for a shortwave radio to use as a demodulator for my
spectrum
analyzer, so I can listen to the signals I see. I don't have a shortwave
receiver right now. Can someone make a recommendation, preferably for
something relatively inexpensive?
Thank you!
