HRII
Today during postflight I discovered a hole in the upper side of the air
intake tube to the fuel servo. This thin fiberglass Y shaped tube was
fiberglassed into the bottom cowl. The hole was caused by not enough
clearance between the tube and the starter. I plan to make a small
blister in the tube but can foresee some difficulty trying to sand that
area on the inside of the tube. Anyone else have this problem?
The second problem is an ongoing one in which I would like to correct.
When I transmit on either com radio, the sidetone is way too loud, not
so much my voice but the noisy background of the engine at cruise power.
On the ground it is fine, airborne it is terrible. My senhouser book
may have mentioned an adjustment screw on the mic and I will check that
tomorrow.
BTW, my sidetone adjustments in the Audio adjustment section are at the
minimum level for the GNS-480. The SL-40 has an adjustment in the
System setup.
Thanks for any and all help.

Hi Jim,
I can't help with the air intake problem, but I have dealt with the com pr
oblem before. The fast easy solution is what we call a "Mic Condom". It is
a foam rubber cover for the microphone that David Clark sells. They are ver
y inexpensive and only take a second to slip over the microphone of your he
adset. They also make one that has a little leather cover on it. Both work
well. We were getting terrible cockpit noise in the radios in our helicopte
rs until we installed these on the crew's mics. I hope this helps.

Also, I think there is a sidetone adjustment on the intercom.
