Atlas has two Narco coms, a Narco DME, and two Narco GS/VORs. All work
perfectly, all the time.

I've not quite figured out where the anti-Narco sentiment come from,
but it's almost as insidious as the anti-Microsoft attitudes out there.

Jay,

It came from avionics shops that got pretty ****ed at Narco when Narco
decided to pull all service into the factory. Narco's reasons for doing
it are understandable, and I think make sense, but the avionics shops
have never forgiven them for taking away a good chunk of their repair
business.

Jay, I can give you an indication why they have their reputation!

An aircraft owner had Narco in his aircraft and said they were 'now'
ok so we took his advice, but...

Purchased 2x MK12D+, CPM136, IDME891 approx 3 years ago.

The IDME891 (ILS/DME) does not work properly at very low frequencies
(around 108.1MHz) the ILS is ok but the DME doesn't always work. The
first flight showed a problem but since it was subsequently not used
at these frequencies for some time the fault was not discovered for a
considerable time.

Both MK12D+ NAV/COM had Transmitter audio failures. Apparently it is a
known diode failure problem. Now I know what happens when you have a
COM failure when overflying a military airfield :-(

The latest is a severe dimming of the NAV display and the first digit
has failed completely.

The CPM136 AF panel produced smoke when COM 2 button pressed.

The IDME891 saved us panel space and should be ideal but the
intermittent DME reading problem has still to be solved.

Awful tale of woe snipped

Okay, I'd be plenty ****ed, if that were my plane. I just haven't had
any of those problems, thankfully!
