Bob, I have an Apollo SL-30 radio in my RV-8 which has a rather unique problem;
on the ground, even with the engine running at high RPM, the radio transmits
and receives flawlessly. In the air it's a different story. As soon as I take
off, a loud background noise begins which makes receiving transmissions nearly
impossible. Usually, sometime during the flight, this noise goes away and the
reception is crystal clear. The background noise doesn't seem to affect transmissions
I have a belly mounted Comant bent whip antenna. Coax connections are tight. Any
idea of what the problem might be?
Thanks,
Walt Shipley

Do you have a hand-held transceiver you can connect to
this antenna? It would be useful to know if the noise
in coming in through the antenna or elsewhere. Does
the noise go up and down with the radio's volume
control?
I presume you've explored potential antagonist devices
in the airplane. Can you do a test flight with fuses/
breakers pulled for everything except engine and radio?
Have you shut the alternator off to see if the noise
goes away?

I'm looking for a place to get some good 4AWG welding cable. (Small amounts-
of course). I see McMaster-Carr has some, but I would prefer to get both
black and red. Does anyone have any sources? I see some on Ebay also.

Is there a squelch on the monitored frequency? I haven't messed with an
SL-30 enough to know, but I could imagine that the monitored frequency my
pick up noise and drown out the primary frequency. Total conjecture on my
part. Discard as necessary.. :)

What about your local Tractor Supply, Orscheln's, Atwoods, fill in your
local farm supply store. Welding supply outlets, too. If you can't get the
red and black, Harbor Freight has those colors of shrink tubing for cheap.

Like anything else, there must be good and bad quality cable available out
there. What would be the difference to look for?

If not seen it in colors in my local suppliers inventory.
The stuff I get here in Wichita is from a local welding
supply store that supplies my CO2 for the environmental
chamber.
See:
http://aeroelectric.com/Pictures/Wire/4AWG_Welding_Cable_1.jpg
This stuff is designed primarily for rough service . . .
lay out on gravel roads and be run over by dump-trucks.
Local pricing for cut lengths is about $1.25/foot

I would recommend the VU-TRON cable. It has fine strands and is very
flexible. Your application may or may not need the flexibility. It is
also
very durable. I was only able to find it in orange, but will use shrink
sleeving to identify. It is a little more expensive but for me, worth
the
extra cost.
My $.10 worth (inflation, you know)
