A couple of days ago I received from a friend of mine a Harris RF power pallet salvaged from a scrapped equipment. This pallet would be able to dissipate apx 300W PEP (black) on a 50 ohm load on ∼800 Mhz.
Unfortunately I have no documentation for this. I do have the schematic but is quite a poor copy (see below).
Seems this should get a bit more attention from me next days and see whether I can make it work (static) on dummy load and then add some modulation. Unfortunately I lack both a good dummy and an attenuator for the SA, but maybe I will build a simple sampler. I will also try to find more info on the internet, but I have no idea what was the model of the original, scrapped equipment. So expecting some fun with this, but, if will work, I might get to be the owner of a 300W QRO for 70cm band. 🙂
