[Elecraft] Need KAT2 Help

[KG3VTomZ at gmail.com]

Don,

Thanks again for the help. I think this is working and I will move ahead. I  
just need to install my new KNB2 and I should be ready to get the rig back  
in the operating position.

I do not have a major gripe with the KAT-2 directions, but it could use an  
update. I have a fair amount of building experience at this point, and I  
found myself in 2 or 3 uncertain situations. But the end result is fine, as  
with all my other Elecraft builds so far. I continue to be very impressed  
with the design of the K2 and accessories.

73,

Tom KG3V
