Update on Band Tracking

My K3, upon moving it to a new operating spot now has a tracking issue. I took off the cabling to ease moving to another room. I reinstalled the cabling. However several bands do not switch ON THE KPA 500 when I change bands on the K3. If I hit the key the KPA 500 immediately changed to the band the K3 is on. So RF switching works.

In the CONFIG Menu I went through the BAND MAP and made sure each BAND was “IN”. But a couple although IN do not follow the K3.

Any suggestions ? I will update the Firmware since what I have is a few behind. That may cure the problem. In the interim please share your suggestions.

Thanks

Re: Update on Band Tracking

Bill:

You mention a good point......cables and connectors.

To that end, I find that just inserting a multipin plug into a connector
is not good enough. I know those retaining screws are a pain to deal
with, but they are there for a very valid reason. They assure the plug
is fully engaged and they assure it is secure. Frequent moving
equipment on the desk or shifting it around will allow a connector to
work partially loose. That causes intermittent and unreliable operations.

Always secure those connectors as intended. Time saving short cuts are
not allowed.

Re: Update on Band Tracking

In reply to this post by Jim Danehy

Be sure to check the pins on the AUX-IO cable connectors. The small DE-15 pins can easily be bent, and if so they may short to another pin or not make contact at all, causing the exact problem described.
If they are bent, you may be able to carefully straighten them, but most likely you will need to replace the cable. I use short adapter plugs that are straight through, connected at the AX-IO ends in situations like these. If the adapter plug breaks, it is much easier (and cheaper) to replace it than to replace the original cable.

You are getting very good advise this evening. Make sure the connections are good, and your KPA500 should properly follow the K3 again.
