[Elecraft] [K3] Assembly question

[Mike]

Thanks, Terry,

Yeah, I don't want to bend anything. I'm pretty sure the board is seated 
properly, as it is in contact with the stand-offs. Maybe the stand-offs 
are a tad long.

Don's explanation that the purpose is to keep the DSP board from flexing 
sounds good, so leaving it out isn't the best idea I've had. If I can't 
tighten it enough, I m thinking I may stack some more washers with it, 
making sure they don't contact anything they shouldn't.

If it's a problem on more than a coupe (and it seems to be), I'm really 
surprised that Elecraft hasn't addressed it.

73, Mike NF4L
