My 300 has issues. When I key the "push to talk" other aircraft hear me key but don't hear the transmission. I noticed on the panel of the 300 I see the "T" for half a second then it goes away. I pulled the 300 and looked around and re-installed. It worked for a day but that was it. I also suspect the VOR is wandering or wondering where it is. LOL. The radio on my KX 135 uses the same everything and works fine.
Yes... I Need a unit. I was tempted to purchase a 300XL.
and do away with the 300.
