W9SZ Almost QRV On 78 GHz
Kudos to Zack W9SZ. Zack is getting closer to being QRV on 78 GHz. He is using a dish with a flat-plate splash feed. Zack mentions, "I pretty much copied a design by DL2AM. My 78 GHz station isn't done but it's getting closer. I think I need about +20 dBm of drive at 12816 MHz to drive the tripler for the harmonic mixer. I got some FET's from Jeff WA3ZKR that are rated at +20 dBm output through 18 GHz. Working on a circuit for that. I have an s-parameter file, which took me a LOT of runarounds to finally get. The company that originally made the FET's has changed hands several times."
