The KPA500 is "inhibited" during a tune when the key line is opened (not grounded). Although it does not produce high-level RF, it is *not* in "Standby". The KAT500 will close (ground) the key line when it is done immediately restoring full output.

As a follow up the recent information passed along on the subject under another thread (* on KPA500) I am looking for some additional clarification. I was under the impression that KPA500 would go into standby automatically when the KAT500 went into a tune mode. Apparently this is not the case unless I have something set wrong. I have found when changing bands if I initiate the K3 “tune cycle” the KPA500 will not go into standby.The KPA500 goes in and out of transmit mode and eventually will go into a "soft fault" if there is an initially high (SWR) while the KAT500 continues to look for a match. The fault due to high reflected power of course is as it should be and must be cleared to proceed. Just curious but is this correct expectation or is there a set up function I missed that automatically places the KPA500 in standby when the As I said I was under the impression that whenever the KAT500 did a tune the KAP500 would go into standby. This is not a major problem as I have set up the KPA500 now to go to standby whenever I change bands as well as initial start-up. I am still curious however if I missed something.
