Continental Microwave PL71090 UHF amplifier

Postby G4GUO » Thu Jun 04, 2015 10:45 am

This is a real long shot but does anyone have any information on the above
broadband 100watt UHF TV amplifier. I am after the pin out for the remote
interface. I have been told these unit work well unmodified on 70 cms.

Thanks Dave,

I have figured out which pins are fwd power / reverse power and PA current.
Two pins have 28v on them and one 5.7v as to the rest I am not sure.

It seems to be tuned to the bottom end of the TV band and I have managed to get
> 100 watts of carrier out on 437 Mhz. Not tried it with digital yet.

****** Update Arthur sent me the required information, thanks all. *******
