Hi guys.. 

ast week i did a harness to hook my tkr-750 ver 2 to a URI

here is what I did:

tkr-750 pin ----- uri

8 to 22 (ctcss tone to tkr)
9 to 26 (voice to tkr)
10 to 21 (audio to uri)
12 to 19 (ground)
16 to 1 (ptt)
17 to 8 (cor)

I dont need the cor cause I want to do all the signaling by dsp but still hoocked it up in case..

So does this make sens? cause I cant have the ctcss level right.

I try to switch the ctcss and voice from left to right in case I had reverse the wiring.
put both channel as tone and voice to test. no go I cant send ctcss from the URI.

I know I can send it from the repeater itself.. But I want to control when it is sent.

Thanks for taking the time to help me ;-)
