KPA500 strange response
Locked
 
|
No matter how I change bands (k3, KPA front panel switches, or KPA utility), if I select 20m band, the KPA front panel displays 21.1. If the K3 is turned off, the KPA responds correctly to front panel switches or utility buttons. I have reloaded both K3 and KPA firmware to no avail. If I send rf out, the KPA switches to and displays the 20m band. Any ideas?

Both cables seem ok. Also, if I select 12m on K3, the KPA goes to 6m. I'm just a little confused.

Solved. It was one of the cables. Anyway I believe so. I took the KAT out of the control loop and all is well with one of the cables but bad news with the other. Must be intermittent as it ohm 'd ok.

How did you determine that the cables seem "fine".
Did you do a continuity measurement on each pin? Did you check for shorts between adjacent pins. If selecting 12 meters on the K3 produces 6 meters on the KPA500, then there may be something awry with the BAND1 data output from the K3 to the KPA100. That is pin 3 of the cable. 73, Don W3FPR On 8/3/2016 8:12 PM, Harlan Sherriff wrote: > Both cables seem ok. Also, if I select 12m on K3, the KPA goes to 6m.
