hold of a couple of vhf Taits T700s, I have a board that I designed to fit
inside of the radio where the selcal board lives, and correct programming
allows you to turn off and on the APRS using the AUX button, It used the TT4
dip chip only problem I found is you have to be committed to the project as
the chip ‘MUST’ be soldered to the board, but worked very
well.<o:p></o:p></SPAN></FONT></P>
