Sometimes its the simple things that trip us up, Used to spend hours with OC71 & OC81 transistors, but that was years ago.... Cough cough..... 40+ years ago, mind forgets things.

Thought I would add the VK3YE AGC.

Anyway after several hours of pondering over the strip board built non working AGC, I had a call from Wife... can I take?
fresh towels down to the beach for the Grad kids.

Got back, fresh eyes, transistor pinout I had found on the web was wrong. Swapped the round, and all seems to be nicely
working now, I even attached the re-claimed S meter from an old Trio transceiver. Alls works well now, just have to make a
better PCB up for the final build, and add the external pot and bypass switch.

This bItx40 just keeps getting better, could take a while to get it into its case tho.....
