ICM rerocked a pair for me last year. Not a problem. They were for
the CR1010 from 450 to 444Mhz.
From the thread Eric suggested you contact ICM and send them the whole

Turn around time was less than 10 days.

The answer to that these days is, How much do you stand to lose?
If your Board/Officers consist of people living in $500,000+ houses near a

CATV can have leakage from 11 MHz (DCT return carrier) clear up to above
1100 MHz (digital video/data carrier)...
CATV leakage a lot of the time in our experience has been the in home wiring
that is either using poorly shielded cable (i.e. RG59 or Lowes/Home Depot
RG6 or anything from Rat Shack)

Yes. Kenwood has a firmware fix for this. No big deal at all.

Yep, sounds like high voltage noise from a dirty insulator, more noticeable in
foggy conditions. Dirt attracts moisture and at 12,000 Volts (or whatever the
potential is) you get small shorts that crackle, like in the back of a dirty TV
set.
If you track it down to a Power Company's insulator,

The squelch tail problem with motorola portables on the tk-850 repeaters.
Something to do with the reverse burst timing or something. We sold three new
'850's to a customer and suddenly all the motorola portables started having a
squelch tail at the end of their transmits.

I am sure you can get the firmware for the reverse burst mod. I have it but
you need to get a customization report before it can be released.
