It Depends which model you have. I have all the 450 to 470 models which
easily
go down to 440. just readjust vco voltage for your freq and realign the
front end.
they all pull down to .25uv for 12db sinaid sensitivity. If you got one of
the 470 to 512
models, you have to change some components in the front end but it can be
done.

Subject: [Repeater-Builder] Re:Kenwood TKR 820
Some TKR-820 repeaters will not tune into the ham band.
I sent one in to be tuned in the ham band, it's still here in the
box, to Kenwood East for a complete alignment and tuning.
Kenwood East could NOT get the unit to tune into the ham band and
remain stable.
They did test the unit further and could make it play well just at
450 but not below.
The repeater was then programmed for GMRS, perfect. Met and exceeded
all factory specs.
I know some will tune as low as 441, and at least a handful of units
we've had won't tune into the ham bands.
Maybe we don't have the right alignment data and we are not Kenwood
experts but after the shop couldn't get the one tuned, it didn't seem worth
fighting with the units further.
