Hi Bob, no not really but a couple of things came up recently that piqued
my curiosity.
I rented a RV12 from the local flight school and the background noise on
the radio was loud. It was fitted out with a Dynon and a Garmin SL40. I
=99m
not particularly interested to dig into it but I was look for a =9Cti
ps=99s and
tricks=9D document that I could pass onto the owner.
The noise sounded like =9Celectronic hash=9D and could probably
be filtered out
on the feed to the radio but that approach doesn=99t address the root
cause.
The other noisy radio gremlin is on a friend=99s C150. I haven
=99t dug into it
yet but it sounds awfully like a failed diode in the alternator. I will dig
out my oscilloscope and take a look once the weather has warmed up.
Cheers, Paul

If its a dynon you can try entering settings/radio and turning mic gain to
25%.
You enter setting by long press two right hand buttons simultaneously.

I have a very fuzzy memory of some early Dynon screens emitting RF hash.
Might be worth perusing the Dynon forum archives to see if something pops
up.

Paul,
I have some ideas about how to fix noise problems.=C2- The trick is two-f
old.=C2- One is to eliminate the source noise.=C2- Two is to make the d
estination more immune to noise.=C2- If you want my advice, send me an em
ail.=C2- It's free and worth every penny.

Will,
The EFIS is a Dynon but the radio is a Garmin SL40. If not familiar with
Dynon, is there a possibility that the mic input would be routed through
the EFIS to the SL40?
Thanks, Paul

I'm not Will, but that would be extremely unlikely (unless we're talking
about Dynon's intercom).

Ah...with the dynon system you can control the radio settings through the
main screen. Dunno if this would work with a garmin radio.
