After a lot of research, I bit the bullet and upgraded my KX170B to an
MX170c. It was a direct slide in replacement, my KI-214 worked immediately.
The same evening I replaced it I tested the glideslope and it was right on
the money. The only thing I noted is the squelch preset and night dimming
preset were not adjusted to my liking. But both were easily adjusted with
front screw adjustments and a jewelers screwdriver.

This Friday I'm heading over to the avionics shop to check the calibration
of my two vor's to make sure their in spec for IFR.

Got to say I love the flip-flops and it sure beat the alternatives from a
cost/installation stand-point.

Good luck,
tom

All,
I am looking to upgrade the avionics in my '78 Mooney 201. I am going to
swap out the KY196 and KNS 80 for a Garmin 430 which will drive the
KCS-55A
HSI, which leaves me with a KX175B driving a KI-204 as a backup
ILS/NAV/COM.
It would be nice to have a "flip-flop" option over there, and someone
suggested putting in a Mitchel TKM 170, as it is a "plug and play"
replacement.
Anyone have any experience with this? Will it connect to the glideslope as
well as the VOR?
Thoughts?

Ian
