1. What radio should I buy between the two: Yaesu VX-7R or Kenwood
TH-F6A
2. Where should I buy it from (price) or maybe someone sells one used ?


Without making a judgement call on your questionable comment regarding
talking back on possible non-ham frequencies, I'll make two comments on
those two radios. I have owned both in the past.

I preferred the Kenwood for two primary reasons:

The Kenwood was capable of receiving SSB in the HF frequency range,
albeit the sensitivy was EXTREMELY POOR in that regard.

I highly prefer the Kenwood Menu system.... it was much more intuitive
to use compared to the Yaesu radios.

Both are well built solid transceivers, though.
