When transmitting, the pitch trim indicator display is affected and I get a
crackle
in the headphones.
To try and resolve the problem I have run a temporary aerial forward through the
firewall and around the outside the fuselage about 1m offset, onto the dipole
aerial from the rear of the rudder so that it is clear of the pitch trim at
the rear of the fuselage and connected the radio to its own power source all to
no avail.
Ive read previous posts on this forum re the pitch trim interference and assume
it will not cause any problems. How can I reduce the crackle while transmitting
as it is fairly loud and cannot be reduced by altering the squelch setting?
Ive cleaned all the earth connections and can only assume the crackle is being
somehow induced via the pitch trim wiring which I have separated as far as
possible
---From the antenna and the wiring to the radio.
All suggestions appreciated.
Thanks,
