Good morning,
I have an interesting problem in which I hope the group here has an easy
solution.
My KPA 500 is hooked to a TS-2000 outputting 20 watts to the KPA500 and
displays the following abnormalities :
1. At frequencies between 4581 kc to 4601.6 (we are working on MARS
frequencies) using U
How are you handling the PTT? Direct from the KPA-500 to the TS-2000
via the PA Key on the amp or by the KPA-500 Aux connector pin #10.
Check cables as one of those commands is being dropped.
Add a ferrite choke on the PTT line if using the PA Key command
method. Or, reduce drive power
4600 KHz is the threshold for 80/60 meters. Below is 80, above 60. Your KPA is
trying to decide which band it needs to be on and is switching back and forth
with the modulation as it causes the frequency to change.
The delay is simply the band change. It would require firmware changes to fix
