Hi everyone: I've shifted my focus from WiFi frequencies to an HF project and I need your input! I need to generate 400W+ HF (2-30Mhz CW) . Any fixed freq. in there will do, AM or SSB will be extra. The purpose is to develop a next gen electronic modification for the Bird 43 watt meter to give it a new lease on life. Vintage gear is a fave of mine. I can do pulsed/keyed modulation to investigate PeP. I need some decent CW power for testing. I have a 40W Ebay kit on order, but that's backup as I am a learn by doing type of person. I have a lot of experience at VLF FET hi wattage pulse & PCB design and SOA for the transistors, as well as custom snubbing for absorbing back EMF/reflected power to prevent FET avalanche. Anyhow, please have a look at this 4Mhz Tesla coil driver. High efficiency, I was wondering if a LPF or proper output inductive resonator could clean up the output for my uses. It's NOT for Tx, I will dump the RF into a diy 50Ω load for precision O'scope avg & PeP RF measurement. http://richieburnett.co.uk/hfsstc.html
