George, can that program allow transmission on 49 mHz? If so, you could use an old portable, battery operated baby monitor receiver. I did that years ago with a radio shack model that had a belt clip. You could also just use a portable scanner, but that little receiver was great and the 9v battery lasted forever. I'll dig one out of the junk pile and get a model#, I had about three of them I used after their primary mission ended. Bypassed the mic input on the transmitter and fed line audio. The great thing was that the transmitter had a very fast attack, slow-decay AGC for the audio, a dynamic range of about 30db, and it was perfect for monitoring HF sideband on my big old tube rigs that did not have product detectors... could just set the RF gain way down low and let the baby monitor take care of the rest.
That monitor in it's designed configuration (listening to our daughter 26 years ago) was very, very sensitive. I remember listening from the shack in the wee hours of the night, the monitor was on the second floor, and I could actually hear the motorized zoning valves in the basement winding open before the circulator and boiler kicked on.
