So swap the RX and TX radios. You can prolong the life of the TX radio by cutting the power down by at least half, or even to 1/3 as long as it stays clean on a spectrum analyzer. >Used VHF equipment in my part of the country is getting next to >impossible to find. So look elsewhere. >My question is. Would it be possible to use an ICOM V8000 2-meter >mobile radio as my transmitter? Your original; TX radio burned itself up because it was not designed to be a continuous duty transmitter. Do you expect another intermittent duty transmitter to behave any differently? Get yourself a radio designed for the job and leave the intermittent duty mobile radios where they belong - in mobile service. >Coming from my controller I need PTT and TX >audio going into my transmitter.

Bro-Comm has the surplus Canadian high-band repeaters - these are the cheapest currently available high band factory repeaters. Note that these were made for 136-151 but will go to 156mhz - and all these will take is recrystalling (probably under $100) and tuning up. They come with the power supply option that auto-switches to a back up battery on a power failure, and charges the battery when AC is restored. Look also at <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3066360625&category=296> If you chose to get an MSR-2000 and add the backup battery you'll need this - and when I looked it was going for $5 - the connector by itself is worth twice that and more. Where else can you get a real factory-built Motorola repeater, set up on your channel, for $700 ? Add a real repeater controller like an Scom 7K, an ACC, a Link or a CAT controller and you have a complete package. There are several ways to interface the MSR to a real repeater controller, one way is here: http://www.repeater-builder.com/msr2k/msr2k-conversion-k4hal.html Another way is here: http://sonic.ucdavis.edu/so02004.html A third way is here: http://www.wa8dbw.ifip.com/MSR2000.htm And if the MSR doesn't fit your needs, look here: http://www.repeater-builder.com/rbtip/custombuilt.html Mike WA6ILQ Yahoo!
