KI-209 VOR/LOC/GS Indicator adjustment

My KI-209 VOR/LOC/GS Indicator is averaging about 7 degrees off of calibration
on VOR checks. Its driven by a KX-155 and I'f like to adjust it to within tolerance.
I don't have a manual for it but I know the adjustment screw is behind one of
the two upper panel mounting screws (I think one is the LOC adjustment and one
is the VOR adjustment).

Can anyone tell me which screw is for the VOR radial calibration adjustment?

Thanks -

If you are using it in a certified aircraft take it ot a reputable
avionics shop. especially if you are flying in IMC.

This group is big on saving money by "do it yourself" and I am one of
the biggest proponents of that, HOWEVER this is an item where you are
way in over your head... Pull the indicator and the 155 and drop them
off at the radio shop if you feel that you must get dirt under your
nails..

denny...

RIght on Denny.
I can remove a splinter from my finger, deliver a calf but would not
want to set a broken leg.
I would leave the avionic in the plane and fly to a good shop and let
them use their equipment.
They set things more accurately with their signal generator. Cables
and antennas can also make a difference. Besides, you are now legal.
I fly for some attornies, you want these dogs on your side because
they can bite very hard.

NOT!!!

This adjustment is very easy for a qualified avionics shop to do (takes
maybe 5 minutes), and there is absolutely NO reason to take the radio and/or
indicator out of the plane. In fact, it's possible that the adjustment on
the bench will not be quite as accurate as one done "in situ".

At least one radio shop I know of has a policy that they will align VOR
indicators free, for life, if they sold/installed the equipment.

I don't think so.. I'm an electrical engineer and can explain the physics
of why and how a VOR actually works in minute detail. The calibration adjustment
is not rocket science and does not require the magical powers of an aviionics
tech. I just wanted to find out which screw was the VOR adjustment and which
was the Localizer adjustment on the KI-209.

You all make similar calibration adjustments to your altimiter via the Kolllsman
setting beroe and during every flight. Tweaks to the VOR calibration are
required from time to time especially if you have replaced a NAV antenna as I have.

I called a friend who owns an avionics shop and he told me which screw
was the VOR adjustment and I've zerio's it now with a test set another
friend had.

Thanks

Exactly... it is not rocket science and no more complicated than calibrating
your altimeter to the local altimiter setting. I would not recommend to
most pilots (nor would I recommend that they repair their own computers)
but for those who have the proper knowledge it is no big deal.

Even rocket science isn't "rocket science" if you have the proper knowledge

So which is which?

Not that I would ever use such knowledge for evil.

The LH side is for the VOR and the RH is for the Localizer.

Keep the greasy side down. ;^)
