Using the KPA1500 with an ICOM IC-7300

[Tom Whiteside]

My early vintage K3 headed back to Elecraft for repairs this week and I'm
trying to get my ICOM IC-7300 to fully interface with the KPA1500.   I have
followed the instructions Elecraft includes in the manual plus a great video
from WX0V - I can key the amp just fine but the amplifier is not tracking
band changes by the IC-7300.    I have the stereo cable going between the
KPA-1500 XCVR Serial and the IC-7300 CI-V Remote control jack and the
KPA1500 key-in RCA plug connected to the IC-7300 send control jack.

 

On the KPA1500, I have the Serial Speed host set to 19200bps and the Serial
Speed XCVR also set to 19200.   Not sure what the Serial Speed Host is for -
it is not mentioned in the instructions for the IC-7300.  Radio Type is
ICOM.  On the IC-7300, the CI-V USB baud rate is also set for 19200, CI-V
Transceive is on and the CI-V Output is on.

 

I have tried other baud rates.   Anyone have any ideas?  Thanks!

Tom,

You might shoot an email to WX0V (his email is on QRZ). Since he 'wrote
the book' he might be able to help you the best. I know his Dad, W0ELM
quite well and he is a great guy so Scott must be too. BTW, I suspect
there may be a 7300 menu setting causing the problem.

Thanks for all the helpful suggestions  - particularly from Dick K6KR and
Rob from Elecraft Technical support.  The KPA1500 tracking an IC-7300 issue
has been solved!  The trick was making sure XCVR SERIAL HOST is disabled.

Tom -

There is no "XCVR SERIAL HOST" setting in the 7300.

Are you perhaps referring to the "CI-V Transceive" setting?
