I used a 4AT for a link transceiver for awhile and I don't remember it being too difficult to interface to my controller. I'll look for any notes that I still may have, but that may take some time. The ham shack is torn apart right now remodeling windows. I remember using a relay to key the HT PT to keep it simple.
Look at some of the notes available on interfacing the HT packet radio use. This should answer your question on how to get rid of the 5 volts. I think the MFJ 1270 TNC may have the information in it. 73, Joe, K1ike -------------- Original message ---------------------- From: "georgiaskywarn" <[EMAIL PROTECTED]> > Has anyone ever done this before on a RC210 before?

Has anyone ever done this before on a RC210 before? Any special
resistor / cap. combos needed? There is 5v on the tx line.
Unfortunately my test bed here at home is a MCC GE Mastr Exec II with
the RC100 built in. Don't think it would be the same as the site
repeater with the RC210.
Any suggestions would be appreciated,
