| Subject: | Handheld Comm Interference In Flight |
During my flight home from AirVenture, I decided to test my handheld radio
in flight. There was so much hum that it was unusable. This was a low-ish
frequency hum, not pulsing. Definitely not what I have heard in the past as
a higher frequency "alternator whine."
Here are the details:
I have the Yaesu Vertext FTA 550 handheld VHF radio. It works great on the
ground.
I plugged in the Yaesu headset adapter into the radio. I plugged my headset
into the adapter.
I have a second comm antenna on the airplane but, since the second comm
radio is not installed, I have the coax with BNC connector readily
available under the front of the instrument panel. I connected the second
comm antenna to the handheld. The two comm antennas are mounted on top of
the airplane, about 3 feet apart.
I tuned to a nearby ASOS. The audio was buried under such a loud hum that I
could barely hear it. I tried a different ASOS; same result. I turned off
the comm radio in my panel and the hum was still present. I did not try
transmitting.
The in-panel comm radio (a VAL COM 2000) does not have any hum.
Other devices in the airplane which were turned on at the time:
- Lycoming engine with primary and backup B&C alternators with B&C
voltage regulators. Ignition is from two newly rebuilt magnetos.
- PS Engineering audio panel.
- VAL NAV 2000 VOR/ILS/GS receiver.
- AeroLEDS landing lights on wig-wag
- AeroLEDS Pulsar NSP wingtip lights with strobes on but nav/position
lights off.
- MGL iEFIS system
- iPad and smartphone
What ideas do you have? Carrying a handheld radio for backup communication
is kind of pointless if I can't communicate with it.

Hmmm (pardon the pun).
More details?
Was the handheld powered from ship's power or its internal batteries?
Did you try it with the handheld's rubber ducky antenna?
Does 'on the ground' mean without the engine running & everything powered
off except the handheld?
Have you tested sitting on the ground with engine running and normal stuff
powered up as typical for flight?
If you get the same noise in the above condition, I'd try shutting stuff
down one at a time until everything's off or until the hum stops.

All good suggestions. I'll add turn off your phone and Ipad, remove any
power adapters for them from 12 volt sockets. They are all known RF
generators.

Matt tells me that my personal sent-messages portal
for aeroelectric.com has been moved to exploit
the features in the Barracuda firewall. The
firewall manages inbound traffic for
all the lists and depending on the rate of
spam hits, it may take up to a minute
before a request is acknowledged and
accepted for relay.
First we're bombarded with robo calls
at all hours of the day (had to give
up my land-line number of 60+ years)
and now our valued email server is
getting bogged down with rotten
