Rotating Beacon vs. Flashing Beacon

Hint...Jameco Electronics has DOZENS of different gearhead DC motors for not a
lot of money. Of course, **I'd** never use an unapproved part in **MY**
airplane, but...

And if I were wanting to look for Jameco Electronics for some type of
hobby motor, where might I find them?

Doh!

I replaced my old rotating beacon with a Whelen strobe unit and have been
very happy. There was no electrical interference, and with the comet flash
the visibility is much better.

I wouldn't put a Jameco motor in my Grimes beacon. First off, the thing that's
there, even before it's geared down has a decent amount of torque. Second,
unless something real bad has happened like it got struck by lightening, it's easier
to just rebuild the blasted thing. The thing is dirt simple and designed to come
apart and be worked on. All you need is a screwdriver, some solvent, some
oil, and if you really want to be fancy a source of DC current to test the thing with.

Mike,

You may want to see if you can get the old one overhauled. My
mechanic saves old beacons and cobbles enough parts together to get
them working again.

When mine stopped rotating - I opened it up and found a plastic gear
had been worn down by the metal gear that meshed with it.

My mechanic installed a new plastic gear, and voila, it worked.

Total cost: 1/2 hour of labor, part was free.

My upper rotating beacon has stopped rotating and I am debating whether to
overhaul it or replace it with one of the new Whelen flashing beacons. The
flashing beacons are all solid state with no moving parts but cost $800 and
I am also concerned about noise since the beacon is located a few inches
from the COM1 antenna. Has anyone replaced a beacon with the new flashing
type? How far from your COM antenna is it? Is there any noise on the COM?
A question for the electronics gurus: Do I even need to be concerned with
noise?

Thanks in advance!
