[Elecraft] Re: K3 & KRC2

Hi John,

Both!

The K3 works with the KRC2 for controlling complex antenna or 
transverter switching. But it also provides amplifier control signals, 
as well as 4 open-drain band-data outputs. These are discussed in the 
Owner's manual, in the "Rear Panel" section.

Normally the band-data signals output a 4-bit binary code that works 
with 3rd-party band decoders, and/or transverter addresses that you 
select on a per-transverter basis. But we could also allow these to be 
used as 4 general-purpose, active-low relay enables for small relays, 
or as signals you could derive relay drive from. The could be mapped 
per-band using a PC utility. This would require additional firmware 
that we haven't written, pending a survey of how operators would like 
to use them.

73,
Wayne
