With that said, the RF deck is not the hardest part to build, even if it is the most critical or performance. Save yourself some headaches and give W6PQL some business. They are dated designs and too be avoided, I now realize. Communication Concepts have simply repackaged the very old white papers from Motorola. His boards are much higher quality and he is an engineer innovating in this space. I ordered the RF board and parts from Communication Concepts but if I was doing it again, I would use an RF deck from W6PQL.

It uses 4 MRF150 FETs in push-pull parallel to acheive 600 Watts from about 6 Watts drive. I wanted to try something different and modern so I setout to build a solid state linear based on the popular EB104 Motorola Engineering Bulletin by Helge Granberg. I wanted more power on HF so that I could make faster progress towards my homebrew DXCC. They never worked that well, but they were a lot of fun to build. This produces a 250 Watt amplifier and has a strip line inductor to match the output. Years back I had helped build a couple of valve (tube in the US) amplifiers using a single 4CX250B on 2 meters. 4-250-A's in a 1-Kw.A 600 Watt homebrew Solid State Amplifier and Power SupplyĪmplifiers are a favourite homebrew project.A Compact 650-Watt Amplifier (two 4X250B).A Medium-Power Tetrode Amplifier (one 7094).How To Run Your (Tube Type - Ed.)
