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. Michelle kontiki wrote: My KI-209 VOR/LOC/GS Indicator is averaging about 7 degrees off of calibration on VOR checks.

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. |

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. -- -Elliott Drucker |

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 :-) "Of course. A child could do it!" - Bones when reinstalling Spock's brain.

So which is which?
Not that I would ever use such knowledge for evil. Don |

The LH side is for the VOR and the RH is for the Localizer.
Keep the greasy side down. ;^) Don Tuite wrote: So which is which? Not that I would ever use such knowledge for evil. Don |
