[Elecraft] K3S + P3 + SPE Amp

[Don Wilhelm]

David,

If you are using the E980297 RJ-45 to DB9M cable, you would connect that 
cable to the XCVR port on the P3.  Then plug the "Y" cable (not the 
Elecraft CBLP3Y) into the PC connector on the P3.  One end of the "Y" 
cable goes to the PC and the other end goes to your Amp cable.  See the 
figure on page 5 of the P3 manual.

OTOH, if you are connecting the PC to the K3S through the USB port, 
refer to the figure on page 6 of the P3 manual.  In this case, you would 
use the CBLP3Y cable instead of E980297.  Your "Y" cable connects on the 
PC connector of the P3 - one end of the "Y" connects to the end of the 
CBLP3Y that would normally go to the PC connector and the other leg of 
the "Y" connects to your amp cable.  If you are using this 
configuration, set the RS-232 menu to USB.

73,
Don W3FPR
