My very first UHF radio was a version of the synthesised FM320 Australian UHF FM CB mobile made by Philips. This was a 70cm amateur version. It was called the FM321. It produced 4W on TX and used channel numbers. I remember someone from Philips discussing producing an amateur band version, at an IEE conference I think.
If I am honest this was one of the best radios I ever had. It had no memories, no fancy gismos, but it worked well. If my memory serves me, I used this with a TV J-Beam antenna (hand rotated) which still had about 10dB gain in the 70cm amateur band.
