I also, have sent an article to Mike for the Repeater-Builders web site, only to wait for it to appear. (I'm still waiting...) I'm almost ready to send it to someone else.

I sent you this very same information, along with other related info for the rptr builders site. The Maxtrac/Radius line had a LPI version in VHF and UHF, usally the 2 to 10 watt version. I have also seen a 1 to 6 watt UHF PA for them. The Mostar, and German Maxtrac have simmular PA stages. I have the schematics for the 2 to 10 watt versions. As Keven said here, removing a couple of stages by bypassing arround the driver and output stage is what is needed. The transmitter PA's get really hot even when "turned down" because the stages draw excess DC current. The transistors are not designed to run in that part of the curve, and become very in-effisient. MIKE, please meet me this week end at The Big Yard sale......... Yahoo! Groups Links Yahoo!
