I inherited one of these with two of radios, one for the repeater, one for a link. On the link PA, the finals were taken out and only the driver was left. Worked fine. -----Original Message----- Date: Monday, August 30, 2010 4:48:49 pm To: <Repeater-Builder@yahoogroups.com> From: "Paul Plack" <pl...@xmission.com> Subject: [Repeater-Builder] Running a Mastr II Repeater QRP
I'm working on a UHF ham repeater project for installation some time next year, and was getting set to build one based on 35-watt Mitreks. I've just been offered a 100-watt Mastr II UHF repeater, complete including the cabinet, just taken out of service in a switch to narrow-band equipment. I helped maintain a VHF Mastr II repeater for a club years ago, and once built a UHF repeater out of a converted mobile, so I know the beast a bit, but have two questions... I don't know the current frequency, but suspect it's in the 460/465 MHz range. Will it move down into the 440s without a lot of grief? Also, I don't need anywhere near 100 watts, and need to avoid abusing the good nature and power bill of my landlord. (Also hope to have battery backup.) Can the 100-watt UHF PA be jumpered from an intermediate stage to the filter, bypassing the final? I seem to recall these would run at something in the 10-25-watt range with such a mod. Or, is this just gross overkill for a local repeater, and the Mitrek-based idea more appropriate? Now, where's my hand truck... 73, Paul, AE4KR
