I've got the chip pulled, and a socket installed, but I'd prefer to wait on sending a chip out until my replacement programmer gets here and I can validate the chip myself.. if I'm lucky it will be here tomorrow.
The unit was previously programmed for 451.125/456.125.. I'm moving it down 10mhz to 441.350/446.350. the data in the chip is CC 84 3C 83 if you want to compare that to what your programmer would put in. _____ From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Steve S.

Some of the TKR720's were borderline, but the TKR820's were OK. You don't have a T band unit or something out of the ordinary do you?
