I picked up some ERBTEK P/N 86-0113-2502 amp boards. Before hacking them so I can use them as amplifiers, I was wondering if someone had figured out how to bias the transistors easly? I talked to an engineer there a while back was told that the transistor were biased using and external (to the board) cpu to determine the bias requirement before the board was used. The board has a CA2820 broad band amp (catv) 400MW driving a pair of MRF134 driving a pair of MRF148 and finnaly driving a pair of MRF150. I was thinking of putting 4 of these boards together and I thing I could get 1kw out. ( I know that I would have to add band pass filters) Any thoughts bofore I start hacking? Tom The reason I ask the question here is for the SDR-1000 had low power out. I will share the answers to those who want the info. Please respond direct Tom Miller AC5TM
