Wonder if anyone is using a Kenwood TH-D7A (or may be an 'E') for a duplex node?
The 'D7 could make for a good node, since it has the ability to operate in full duplex (RX on Band 'A' and TX on Band 'B'). I'd like to know if there is a way to bypass the internal TNC, or to bring out 9600 baud audio (or raw discrim audio) out somehow.
I was initially using a pair of Baofeng's for a portable / full-duplex node... but the Baofeng's are as deaf as a potato!
Unless you want to perform surgery on the radio, there is not an "easy"
way to bring "raw" audio out from the radio.
A possibility is just use the connections from the speaker mic ports. I
suggest using the BAL button to turn the volume off on the band you are
going to be transmitting on.

That's definitely an option Benjamin.... but how do I get COS signal?
I'm not opposed to performing micro surgery, just wondering if anyone has been there and got the T Shirt!
Having said that, I forgot to mention that the issue with the Baofengs seems to be largely with the stock antenna (or should I say the attenuator disguised as an antenna).
Testing with a signal generator seemed to indicate a 10dB loss in sensitivity when using the "antenna".
I've also since switched to duplex=0 (with linktolink = 1) to help eliminate further loss in RX sensitivity due to desense).
