The only radio I've had to run a bonding wire with was my first one, a
Babcock 3 channel ca. 1954. They wanted everything bonded, from the
rudder control wire, rudder/throttle exscapements, servo case, etc.<BR>up to
and including the engine. Every piece of metal on the airplane,
including the landing gear. What a pain! It was, of course,
AM.<BR><BR>Bill Glaze<BR></FONT><FONT face="Times New Roman" color=blue

However, a few years ago I experienced all sorts of range / glitching
problems in an airplane that had metallic paint, metal cables and other
potential points of metal - metal contacts (landing gear, landing gear door
mechanisms, etc.) Running the antenna through a wing helped a bunch, as it
moved the antenna away from noise generators. The real fix was to wire all
metal objects together with a "ground wire" that was connected to the
negative battery lead. Antenna then worked fine inside the fuse. All this
was with an AM receiver on 6-meters. </FONT><BR><FONT face="Times New Roman"

experience occurred with a different airplane that had a small fuselage and
a lot of servo leads near a good portion of the antenna, range was
nonexistent until moving the antenna to the wing. In this case the receiver
was single conversion FM on 6-meters.</FONT> <BR><FONT

to metal generated noise is (at lease with AM), and antenna - servo lead
proximity can be. </FONT><BR><FONT face="Times New Roman"

any problems with dual-conversion FM on 6-meters with the antenna inside or
outside the fuse, although I maintain a couple of inches separation between
servo leads - cables and the antenna. </FONT><BR><FONT

size=3>Current flights with the Partner haven't demonstrated any issues with
the antenna inside the Kevlar rear of the fuse (as expected), although I've
flown head on trimming stuff that has put the carbon front of the fuse
between the antennae.</FONT> <BR><FONT face="Times New Roman"
