In order for the rear panel connections on the 15 pin molex to function you have to have pins 1 & 2 shorted together. also make sure the take over button is out and no LED lit. if your using external controller the the repeat button is out . if your using DSP to derive your ctcss pull the serial eprom(93c24) from the CTCSS board this places the radio in CSQ mode. gud luck -- Thanks in Advance Bob Brown, WØNQX Kansas City Metro Area http://drsm0ke.net http://byrg.net http://sm0kenet.net http://kcdstar.byrg.net Quis custodiet ipsos custodes? -- On Sat, Aug 24, 2013 at 2:12 PM, Chris Andrist <chris.andrist@gmail.com> wrote:

I am having problems interfacing my TKR-720 to app_rpt with a URIx. It does not detect a signal on pin 13 of the repeater. I am using COS so letting the URIx do the work for me will not work.

Has anybody interfaced one before? If so, did you have to do anything special?
