See pages 15, 16, and 27 of the KPA500 Owner's manual for a description of what the 15-pin ACC cable can do for you.
It amounts to band information both ways so the amp can switch bands from the K3's band information before you provide RF, the KPA500 front panel band buttons can bandswitch the K3, and K3 drive power can be set to two different levels based on the amp's OPER/STBY switch. My K3 provides 30 watts when the amp is in OPER, and 100 watts when the amp is in STBY. 73 de Dick, K6KR -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Dave Sublette Sent: Thursday, October 10, 2019 04:15 To: Elecraft Discussion List <[email protected]> Subject: [Elecraft] KPA500 with K3s Good morning, I am building the KPA500. I have the K3s. Can anyone explain, in simple terms, what advantage there is in using the KPAK3AUX cable instead of just using the Key Line cable?
