DME recommendations

Keep in mind that a DME is a transmitter.
At some point in time, the transmitter final stage power transistors
are going to die and need replaced. When they need replaced depends on
how often you have it turned on.

(PS... A new stack, eh? So does this mean the Navion will be at OSH this
year? :-)) )

Don't waste your money on a DME. Too much maintenance.
Purchase a good used IFR GPS.

I haven't had any maintenance done to it. Now the rest of the
King SC stack is a different story. The GS crumped and occasionally
the displays on the KX155's fail. The transponder needs regular
attention and the stupid ADF I am never certain if it is ever working.
I'm in the middle of switching over to a Garmin stack, the only
thing I'm keeping is the KN64.
On the other hand, I'm not sure I'd go out of my way to install one
if I didn't already have one. Back when I put it in, I knew it was
likely to be the first casualty of the GPS era.
