Good Morning Scott,
It seems a shame to put in a radio just to accommodate bureaucracy, but if
you really want to do it, I think I would bite the bullet and find a good used
KR-87.
It is a fantastic radio and is easy to mount.
You might check on that regulation. I thought I read a few weeks ago that
Canada had come around to the US style of thinking on that ADF requirement.
Be sure you aren't listening to an Old Wives Tale!
Try contacting George Dewar of NavCanada and tell him I said to write.

Happy Skies,

They may require that it be equipped wit the original receivers that the
approach required, but do they say they have to work?

Gentlemen:
It looks like at least one of my four teenagers will train for their
instrument rating in our RV-6. It already has a navcom with glidepath and I
have a Narco ADF 140 that I'd like to put in, if only temporarily.
But the ADF came with both a shoe antenna and the long wire sense antenna,
which would be hard to mount on an RV-6.
How would it work without the sense antenna, if at all? Is there an
aftermarket combination antenna that I could use?
I'm aware that ADF appears to be going the way of the do-do bird, but, in
Canada, GPS can only be used for overlay approaches if the aircraft is
equipped with the original receivers the approach required.

I second that. The KR-87 is the best ADF I have ever used. The only
problem is that they are still pretty pricey.
BTW, I have a KR-86 I have pulled out of service (I kept the KR-87).
It was 100% operational when I removed it and I carefully preserved the
harness. Make me an offer if you want it. I think I may have a KY-97A
still kicking around too.

The latest regs-which are still a little ambiguous-state that to do, for
instance, an ADF approach, the aircraft must still have an ADF receiver to
revert to in case there's problems with the GPS, although it's not required
to be used for the approach if the GPS is working. Same applies to a VOR or
LOC approach.
The regs do include the airmanship reminder to make use of all available
resources on board...

| Subject: | Minimum spacing for toggle switches? |
--> AeroElectric-List message posted by: Richard Riley <richard@riley.net>
I'm looking for a spec on minimum lateral spacing for MS24523 toggle
switches. Right now I have them at .75" (spst's - the dp's have a wider
body and are ending up more like 1")
Any one have any opinions, facts, observations or wild guesses that might help?

I just got my Icom IC-A200 (purchased new) radio hook-up in my homebuilt and tried
testing it while the airplane was still on the ground. I live in a fairly
remote area so I wasn't too surprised not to hear any audio chat So for a quick
check I tried listening in on 121.5 while tripping the ELT for a couple of
seconds and only received a low power signal. While trouble-shooting the problem
I tried disconnecting the antenna wire connector from the radio antenna during
the ELT test and to my surprise the signal became very strong with the antenna
disconnected ...? Now I'm suspecting the antenna which was bought new,
used once and removed and stored in my basement for 9 years. Is there an easy
way to check an antenna?
Thanks in advance for any help.
Clay Smith

Just as long as when you are hot there are no sparks!!
Sorry. When things are close we use a fiber plate
about 2x2 between the switches. Other than that for
appearance make them even.

I'm more concerned with them being wide enough apart that I don't
accidentally switch more than one at a time. Any idea what minimum finger
clearance distance is?

You need them both. The radio will work in the "receive" mode for
ball games using only the sense antenna . . . but for "ADF" mode,
you need them both.

That may not have been a valid test. A receiver located in close proximity
to a transmitter may become overloaded to the extent that disconnecting
an antenna reduces signal strength to acceptable levels and the overloaded
receiver recovers.
Folks who have tried to fly formation often find they cannot communicate
with an airplane a few yards away. Many insert a 10 db attenuator in
the feedline for the #2 com (or under the rubber duck on the hand-held).
With a pair of such attenuators in the line for both co-located radios,
the apparent signal strength is 1/100 of what it would be normally
and the radios work fine.
An SWR or other antenna analyzer test is the definitive investigation.
