Hi Mark, Yes it is a happy ending! Regards the 1296 board, it is one made by my ham colleague from a design by Bertrand Zauhar, VE2ZAZ. It places 8V on pin 3 of the PA which makes it more linear than the 6 or so volts that pin 3 of the PA was getting from its pad. I will send you more info directly. 73 Starr ZL3CU
