Brian,
Yes, the KAT500 is protected. That is inherent in the K3 ACC (DB15)
cable going first to the KAT500 and then to the KPA500 There is a
Keyout-LP signal in the ACC cable to the KAT500 (and then onward to the
KPA500).
The KAT500 interrupts that signal (to the KPA500) when the KAT500 needs
to tune.
That Keyout-LP signal is what all the instructions about the DB15 pin 10
concern themselves with.

Hi Don,
Thanks for the prompt response.
Yes, I am using the DB15 and the PTT line. I got it working. Here is my
new cable lineup:
1. ACC on K3 (DB15) >>> DB15 Y Cable | >>>DB15 Cable >>> "XCVR" (DB15) On
KAT500
|
And | >>> "ACC"
on Navigator Interface
2. "RS232" on K3 >>> "XCVR" (RS232) on P3
3. "PC" on P3 >>> "RS232" on Navigator Interface
4. "AMP" on KAT500 (DB15) >>> DB15 Cable >>> "AUX1" (DB15) on KPA500
5. NO PTT LINE into KPA500 or into KAT500
6. No "Key Line Interupter" anyplace.
With this lineup, is the KAT500 protected from the KPA500 keying when the
KAT500 is tuning?
I must admit, I have mightily confused myself in this process.
Thanks again,
Brian W3BW
