Hi all, I received the replacement for the defective KAT1 PIC today. Stuck it in there and #1124 is finally complete. Radio, noise blanker, atu. The progress was also held up by two components missing from the original box, a diode and choke. Then the PIC on the atu was misprogrammed. Got it all straight eventually. Hope to work some of you soon. 73 es gl, Dave AB9CA
