Hi Brian, 

You’re not asking for much, are ya!  From what I can see it would involve a complete disassembly of the ANAN-100D in order to gain access to the relays themselves on the PA board, and I’ve had the thing for less than a day, hihi.  

Yeah, sure, I’ll look it over and see how much trouble I can get into doing it to check out the possibility for you; if you’re sure you don’t want to dissassemble yours instead, that is!!  

73,  Joe K5SO

That might have a significant effect on the passband ripple. Can you confirm that only one bit gets loaded into the shift register?
