Harris 300W UHF Pallet


            

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.

Harris 300W UHF pallet — how good could this be as a QRO for 70cm amateur radio band ?

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. 🙂

How to use Matlab PCBReader objects

Recently I installed a trial version of the new PCB toolbox from Matlab. From Mathworks website: RF PCB Toolbox provides functions and apps for designing, analyzing, and visualizing high-speed and RF multi-layer printed circuit boards (PCBs). You can design components with parameterized or arbitrary geometry, including distributed passive structures such as traces, bends, and vias. […]
