New LA-1K Only band switches via RF at initial power up


Robert Hayden
 

Brand new LA-1K.? RF band switching works ONLY after going from 'off' to 'on'.? After that it doesn't band switch.? I bought it for this feature.? I don't have a data cable (Kenwood 590SG) and don't want one.

LA-1K on 240v.? Paired with an also new HF-AUTO tuner.
LA-1K? Firmware version 1.08M. ? Display version 4

ANY idea what might cause this?? Looks like a firmware issue to me as it seems flawless on the first TX after power up. (changes band and displays proper freq).
After that.... nothing changes.? Meter shows barefoot power going through amp in STBY so it is getting/seeing RF.??

I have similar configuration… Flex 6600M to HF auto to LA1K. I power up amp goes to stdby. Hit tune on flex then hfauto tunes up and then put amp in opr.?

When changing bands I first return amp to stdby then tune on new band and freq. hf auto tunes up then put amp in opr.?

I have no other cables between the 6600 and hfauto and la1k except rf coax.?

Hope this helps??
