Leo: Look around for a used Motorola GR300 repeater. They have a footprint of about one square foot and about 14" high and are quite reliable. I have a couple of them running in the 70 cm ham band. They usually come with a 120 VSAC power supply, but they run off of 13.8 VDC, so you can bypass the supply and run them directly from yoiur rig's DC source. I set mine for 20 W XMT power to keep a limit on final amp heat. They'll fit neatly into a small space in the sleeper area with room to spare. They include a built-in duplexer (UHF). There might be some on the Bay.
Also, I have a Moto UHF suitcase repeater that includes a duplexer. 73, Dick W1NMZ ----- Original Message ----- From: texasexpediter To: Repeater-Builder@yahoogroups.com Sent: 04 February, 2007 15:16 Subject: [Repeater-Builder] mobile repeater setup I drive a truck OTR and at times work with FEMA. Would it be possible to put together a mobile repeater system that could be used in areas without power? I have a generator system in my truck so I have 110 power available. My interest would be in something semi permanently installed without need for putting antennas up or down. I realize it would have a rather limited reach but would theoretically allow an ht user 5 miles east of the truck to talk to an ht user 5 miles west of the truck when they wouldn't be able to talk simplex. With mobiles the effective radius presumably would be greater as well. My questions are is this feasible and reasonable? What would be the least expensive system I could put together to do this job? Thanks in advance for all suggestions. 73 Leo K5LDB
