[Elecraft] kx3 and krc2 problem

[Don Wilhelm]

Noel,

How are you connecting the KRC2 to the K3S? If you are using the AUXBUS 
mode with the K3S, that same KRC2 configuration will not work with the 
KX3 (no external AUXBUS connection in the KX3).  You must configure the 
jumpers in the KRC2 to extract the band data from the serial port data.
Study the KRC2 Jumper Configuration information on page 20 of the KRC2 
manual.

The baud rate of the KX3 and the KRC2 must match, and the KRC2 will only 
go up to 19200 baud.
Set the W7 and W8 jumpers in the KRC2 to whatever baud rate you choose - 
see page 20 of the KRC2 manual.

Are you using a computer application like a logger that polls the KX3 
for frequency information?  If no computer to do that, have you set the 
KX3 AUTO INF menu (Tech mode must be on to see it) to "1"?  That is 
necessary to send band information to any band decoder.

I think you are the first to try the KRC2 with the KX3, so do keep us 
posted on how you make out.

73,
