            Hi folks,

 

This one is a bit odd.  My buddy has a Ford F-150 and installed in the truck
is his TM-D700 dual band VHD/UHF radio. We chat during our drive into work
in the mornings.

Almost without fail when he is transmitting at least once during the 30 min.
drive I will hear what sounds like a siren on his audio Whrrrrrrrrrrr
starting at a high pitch and slowly going down in audio tone freq. He has
grounded the radio, etc., yet the weird noise continues to occur.  Last week
I installed a TM-D700 in my Ford Sport Trac and guess what - now he says I
have the same odd occurrence of the erratic whine syndrome. 

 

My radio is also grounded extensively as I run 1KW on 75 and 40m.

 

Thoughts and recommendations welcome.

 

73,

Dave

Wa3gin
