John,
If you follow the link below, it will take you to a list of full-duplex (and almost full-duplex) radios (old & new). Maybe it will help you to select a suitable radio.

Subject: [AMSAT-BB] Chinese radios on satellites
I am considering picking up a cheap FM dualband radio to have as another travel radio for the satellites. I am wondering which models of the Chinese dualbanders that people
have had success with on the FM satellites. Some ones at good prices are
TYT TH-7800
TYT TH-8600
Jetstream JT270MH and its Lexein VV-898
Anytone AT778UV
Any good or bad comments on these models? Other good models to consider? I do need something with a headphones/speaker jack with leaves out some
of the QYT models.
