I recently flew an older Cessna, in which the NAV frequency select was
directly ON the VOR indicator, as was the DME readout. This just seemed
like good ergonomics to me - no way to make a mistake. Who makes these?
Why do we see them so rarely?


When I purchased my Cheetah, it had a Narco 122 installed. This is a
self-contained VOR-LOC-GS instrument with marker beacon annunciators
on it. To my mind, it is one of the best instruments I have--easy to
use, clear to read, and dead-on accurate.

Narco makes a new model of that instrument, which is digitally rather
than mechanically tuned. It, however, does not have the marker beacons
present on the instrument, which I think is a shortcoming.

The Narco IDME 891 has VOR-LOC-GS and does have repeat indicators from
the Marker Receiver in the Audio Panel (CPM 136M).
