I used my K3 on 495-502 KHz as an experimental station. I got 1mw
output at the XVT Tx output jack running the TEST mode.
For amplifier, I bought a surplus Southern Avionics NDB (aircraft Non
Directional Beacon) transmitter. It is a xtal controlled oscillator
amplified to 100w into 50-ohm
Jack,
You will need the new synthesizer - two if you have the KRX3.
You will also need the KBPF3A. If you already have a KBPF3, there is an
upgrade kit that you can install - the KBPF3MDKT (see K3 Parts and Mod
Kits).
You will also need the KXV3 (or KXV3A or KXV3B) option in your K3
because
These seem to be popular from what I've been reading lately:
