I have a 1977 Piper Archer II with a KX-170B. and KI-214 indicator.
I understand that the G/S receiver is built into the KI-214.
If I replace the KX-170B with a Michel MX-170B will the G/S and Localizer
work OK with it ?
As an aside I am a Radio Amateur who has built and operated radio equipment.
However, I am not familiar with the words "Slip Code" & "Channeling Outputs"
I hope someone can give me the understanding of these terms in normal radio
terminology.
I will appreciate all the help I can get on this one.
Thanks

The 214 works well with the Michel, it's the setup I'm using. Plug
and play! I too am a ham but don't know of those terms. Maybe the
biggest ham on the group will chime in and give us both an education.

In the context of connection between a Nav radio and a GS receiver, these
relate to connections that provide indication of the localizer frequency to
which the Nav radio is tuned, so as to tune the GS receiver to the
corresponding GS frequency.

The KX-170 series of radio has two "channeling" outputs; one for
the external glide slope receiver and the other for an external DME
receiver. Thes are signals that are either grounded, open, or tied
to A+ (supply voltage) via 1K resistor, and are used to indicate the
LOC or VOR frequency the KX-170 nav receiver is tuned to.

DME Channeling outputs are composed of 4 "MHz" signals (M0 - M4),
4 "KHz" signals (K0 - K4), and a 50KHz signal. In the following table,
the - indicated the signal is open, 0 indicates it is connected to the DME
common signal (grounded), and 1 indicates is is driven to +12V via a 1K
resistor:

M0 M1 M2 M3 K0 K1 K2 K3

GS channeling output are composed of 4 "MHz" signals (GS108 - GS111),
5 "KHz" signals, and a 50KHz signal. In the following table,
the - indicated the signal is open, 0 indicates it is connected to the GS
common signal (grounded), and 1 indicates is is driven to +12V via a 1K
resistor:

Hope the formatting holds up well enough for you to see the table.
