K3 - BAND1 output not changing

Dave Hawes
Debugging a problem on a friend's K3.

Using an external band decoder that has pull up resistors, the BAND1 line
output from the AUX connector is always high, and of course that is messing
up the decoding function on about half of the bands.  The radio is working
normally otherwise.

Reviewing the schematics, it is seen that there is a series resistor in each of
the BANDx lines.  If that resistor were to open up, the symptoms observed
would result.  I am not close to the radio at the moment, but intend to check
this out.

In the meantime, has anyone seen this kind of failure, and if so, has the
series resistor been the culprit?

Thanks, and 73 - Dave N3RD
