Hello!
My name is Bill, LZ1SWE.
I have reworked the control board using PIC16F1938 and MIC2981/82 as drivers, dispensing of the myriad of transistors to drive the relays. This simplified the PCB and reduced the size, and I went for trough hole, because
I will start working on a new RF deck/PCB layout soon, with different relays and especially coil positions to reduce mutual coupling and losses, especially for the 1kW.
I have taken RA6 to a driver and I hope that David would help here - can you please take a BYPASS to that pin, so I can build a proper low loss and low SWR bypass section?
RA7 already has the RTS signal for transmitter control, and inverted is not really necessary
I have Gerber's for all of you, that might like to build this for themselves, they are attached.


?

Best regards!
