Hi
I run a Kenwood TS-2000, KAT 500 Tuner and KPA 500 amp.
In the last few months I have been having an intermittent issue with my amp. On some occasions when I have changed bands it will not follow the band changes like the ATU does. So if I am on say 14MHz and change to 7Mhz the ATU changes antenna/band but the amp remains on 14Mhz. Changing it manually, changes the display on the amp to 7Mhz but the amp will not operate on that band (or any other I subsequently change to).
Reinstalling the firmware (1.38) seems to fix the problem but every now and then the same thing happens again without warning (although normally when I am looking to work something I need the amp for quickly).
Has anyone else struck this and if so did you find a solution?
