[Elecraft] K1ZTE - KAT500

[JK Hooper]

Russell, 

I have the same experience with my 7300 exactly, needing to shift to CW mode to match the KAT500.   It’s at the point where it’s just what I do.  

Dick, 

I have the cable for connecting the 7300 to an external tuner, such as the AH-4, and I found that it did work fine for initiating a tune.  But what I want is to use the stored settings in the KAT500 rather than initiate a tune each time, so I have KAT500 in “MAN” setting.  The CW key transmission is what I need to use to activate the right pre-loaded setting for the frequency in the KAT500.   

I did find that the 12 volt connector part of the I-think-it-was LDG cable was so sloppy that it would not stay in the KAT500.   So I just don’t use it at all.

Page 13 of the KAT500 owners manual describes an AH-4 connection between Icom radios and the KAT500.

Does this work for you?

This allows the KAT500 to find a match with low power while the KPA500 is in standby mode.  In SSB mode, there is still the need to activate the KAT500 for the match, however, neither keying the mike nor speaking into the mike activates the KAT500.  A press of the transmit button in the IC 7300 also did not activate the KAT500.  I find that I have to first switch to CW mode for the activation before switching to SSB so that the KAT500 is all set for KPA500 operation.  Is what I am doing the only way to do this?  I have read related posts on this subject but they did not satisfactorily answer my question.
