Geez, was a while since I logged here. I was busy finishing my training a new company and lost track of this thread Well, I finally ordered my VX-7R and Im waiting to get my hands on it. As soon as I get it I'll perform a SW mod (virtual Jumper #3) to enable freeband. Now, Alan is suggesting me to build a Diode Detector (envelope AM detector), or w/e its called, so I can verify if the waveform is an actual AM. I guess I need an oscilloscope or similar to check the waveform in a graph. Is there another way to perform this? As I currently don't own this equipment. I can try using any SW-based solution if any. Ive been also looking at the schematics of this radio Vs. its evil twin aviation brother, the VXA-710. Case and motherboards are almost identical. The Processors and transmitters vary as the VXA uses less options than the VX, but has some additional features like a "VOR". So I guess unless I perform a real field test, all of this chitchat will end in the same, ASSUMPTIONS. Cheers.

This is and old thread, nevertheless I had been looking for years for a dua/tri-band radio that could tx in all bands, and read all sort of posts about AM Xmit not possible, etc. I am an airliner pilot and licensed HAM operator. I will buy a VX-7R for the sake of science, mod it and post results. Will try to make different tests using the air-to-air band with other A/Cs in different altitudes, from 40,000' to whichever altitude I can and hopefully unmask the truth about this HT. I know PAPER manuals/diagrams/specs can hold as much ink you can throw on them, but the truth finally relies on field tests Cheers.
