Update 5/03/22.
I appreciate the good suggestions. Yes I am original owner.
I transmitted from the 940, with the 890 on & heard nothing on either antenna port, going from AM,FM to USB/LSB & CW. Hooked 890 to a dipole, repeated test, still nothing.
I contacted GigaParts. After 10 days ALL service goes to KW USA.
As for KenWood service in Long Beach Ca.... Nothing gets serviced there, phone help only, suggested full reset, two more re-sets attempted without success. All repairs go to New York. Gone are the days to take the rig in.
Urrrrg. Lol
Frankly it seems nobody @ GigaParts or KW gives a Shxxt.
Lessons learned- unpack that radio ASAP & check it out.
