I own one new Radio unit ( RRC-1258MkII ) and one old Control unit ( RRC-1258 ver 1 ) and i am trying to connect those two units with Kenwood TS-480. I already saw and fix the cable for RRC-1258 ver 1 control unit http://www.remoterig.com/v1/bilder/TS480-RRC-Radio-K6.pdf, and i put the correct jumpers at Radio unit ( RRC-1258MkII ) and TTL is connected with control plug, and AUX/MIC with the MIC plug on my TS-480 main unit.
With this connection and the cable i fix from your design at RRC-1258 ver 1 page , i manage to turn on and control TS-480 from my old RRC-1258 ver 1 control unit, but i have strong noise when i try to transmit, The base goes to PTT mode but with a lot of noise. Please advice me what can i do in order to fix this problem of mine.
