First of all, since its my first post in 2012, Happy New Year 2012 have some great DX and no problem with your repeaters!
 
Ok like the tittle say, I need the service manual of a Kenwood TK-840 mobile.
 
I am in the process of building a homebrew dstar repeater, and I need some information on what signal is available on the KCT-19 accessory cable.
 
is it flat audio? is there a way to have flat audio? This radio will be the receiver part of the repeater, the transmitter will be a tk-860HG.
 
I have the programing cable and I’ve been able to program both radio in the ham band, and they are really stable..
 
Anyone can help?
 
And if someone knows a few info, like there is no flat audio output possible from those radio, please tell me so I wont loose time on those radio.
 
thanks
