Posted: Fri Aug 17, 2012 9:47 am Post subject: handheld problems

Let me start by saying I'm the village idiot when it comes to radios so hopefully someone can point out the obvious problem to me.  I'm trying to use my handheld (Vertex VXA 150) along with a set of Peltor 7004 headsets to communicate from my Kitfox.  On the ground with the engine off everyone around the airport hears me fine.  Once the engine is started everyone complains about background noise or static  when I transmit.  A  FOB unicom can just barely hear me from 5 miles out.    I receive fine in flight.  The radio is not wired into the aircraft power, I'm using the radio's battery.  It is the same for both the rubber ducky antenna and the external aircraft mounted antenna.  The headset works fine in other aircraft.  I'm wondering if the headset is picking up too much background noise ? 



thanks,  EG

Most likely - The microphone should be touching your lips, and there are 

mic shrouds available with a hole pointing to the speaker, and a covered 

back to reject other sound sources. (Wind, engine noise.)

Eg

On my older icom if I press the transmit switch on the radio it also

transmits all the noise from the radio mic as well as from my headset

mic. That is same symptoms as you seem to have. The only way to use it 

in flight without all the noise is to plug in an optional remote 

transmit switch which then only transmits from my headset mic. Think the 

icom switch was around $20. from Spruce.
