The COS signal can be changed by using the 760(TOR) firmware. While I would not use a low power 25 watt unit, a H series turned down to 20 watts will perform very well. While the heat sink appears to be a small footprint, it uses the entire frame and was designed by NASA for maximum heat dissipation (as long as the glue holds on the tile!). The Icom IC-Fx21 series radio uses the same design. Make sure the radio is mounted horizontally with free air flow. Do not stack mobiles on top of each other no matter what brand you end up using. If you add a computer style fan to push air up through the heat sink fins the radio will run continuously at 10-15 watts dependant on ambient temperature. You can use a KCT-19 cable or make your own with standard Molex ZHR conn / SZH pin mini connectors and Molex .062 connectors. If you want the Digikey part numbers I can send them to you.

If you plan to run your repeater with carrier squelch only, this will not be a problem. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Dakota Summerhawk Sent: Saturday, March 22, 2008 11:43 AM To: [email protected] Subject: [Repeater-Builder] Kenwood Repeater question I have a few of the TK-760's that I have been playing with the idea of thinking of using as a repeater, can this be done? And if so what would it take? Thanks Peter Dakota Summerhawk ------------------------------------ Yahoo! Groups Links
