Hi:



Questions to the Electric Engineers?



   I have a set of Flightcom Head sets, now the problem I am having

is that everything works fine, while on the ground or while taxing..

but as soon as I am about 1000"  there is no communication at all..

I can hear, but I cannot transmit...



      1> I did remove the cover panel, checked for loose wires or

         connections, and the always first to check item, that none

         of the prongs, touch each other or against any part of the frame

           etc.. everything looks OK.. and tight...





      Remember I can transmit while taxing or on the ground....

Any sugesstions from the Experts,, before I have to pay the robbery

prices at the FBO shop?



Bert

I love troubleshooting questions!

First, your FBO won't be able to help.  The problem won't be duplicated 

in their shop unless you can get them to launch the shop!!! 

First off, if both headsets exhibit the problem ...... I'd rule out the 

headsets. Especially if they both fail at the exact same time.  No 

sympathy pains here.  Strange things do happen, so go fly with someone 

and swap out your headsets for a check.  Much more fun than taking them 

and the plane to the FBO.



When you can't transmit, always check the little 'T' or transmit light 

if your radio has one ..... it'll tell you whether the mic switch 

(transmit switch) is working.  Switches aren't usually altitude 

sensitive, but just maybe .....



That leads us to wiring.  I hate to be the bearer of bad news .... but 

wiring isn't usually altitude sensitive ..... unless we're talking much 

higher voltage. 



So, now we go to the comm panel, if you have one.  You know, the panel 

that allows you to switch or monitor more than one radio.  They have 

amplifiers in them, and capacitors that can be altitude sensitive.



  If no comm panel, then the culprit may be your radio(s), which has 

capacitors in them too ..... and a lot more of them.  I'd try and find 

someone that'll let you swap radios for a test.  Must be the same 

make/model ..... usually ..... nothing is ever always!  Some radios are 

made as replacements for others.  The trays and radios have to be 

compatible.



Come on back after you've had a chance to do your testing ..... it'll be 

cheaper.  Also, write down everything that is pertinent to your 

installation .... that may narrow things down a bit.
