[Elecraft] KRC2 with K3, KPA500 and MH MKII keyer

[Mike Fatchett W0MU]

KRC2 built.

It appears there are a couple of ways to wire the KRC2 with the K3.  I 
have the KPA500 and am using the Aux bus so I think I should use the aux 
bus.  The KRC2 will be used to drive an ICE 419 Bandpass filter unit.

I would appear that all I need to do is connect pin 6 on the KRC2 to pin 
2 on the 15 pin connector and pin1  to pin 5.

Why would one want to hook up using serial ports with or without logging?

The entire setup will consist of a Microham MKII keyer or MK2R+ , K3, 
KPA500 and KRC2.  It would appear that I would need another 15 pin 
splitter to run the MKII, KPA500 and KRC2 all on the the Aux Bus.  I 
assume that the splitter that Electraft provided is 15 pins straight 
through?
