For simplex use, you have to have an external antenna relay.

It works great! I have a TKR-750 that I would like to put into service on a simplex frequency. The advertising literature and the service manual both state that it can be used on simplex using only one antenna, and I have set the programming to "simplex" rather than "repeater." However, I cannot find anything stating which antenna to use and/or what other cabling must be used, what other procedure to follow, or what other step must be taken. Is it as simple as screwing the antenna coax into the TX connector? The receiver works just fine, and I can hear strong local signals by alligator-clipping an antenna to the RX input. My next step is to alligator-clip an antenna to the TX input to see if I can receive as well there. Does anybody have any experience with either of these (or similar units) that can point me to the proper procedure or documentation? 73 de Dave WB6KHP San Jose IRLP 3246 / EchoLink 525493 pushing sine wave energy through the atmosphere since 1965 -- dave6592 [at] accesscom [dot] com - http://www.accesscom.com/~dave6592 Dave Schultheis, San José, Silicon Valley, Santa Clara County, CA, USA
