I don't have any problem with 50 watts VHF,UHF or 100 Watts on 40 meters. Noise cancelling David Clark headset/mike for all operations with the top down. Don't go mobile much, but have. Watch the rigs and the heat sinks heating up on the leather seats!!! keep em on the floor. I just renewed my Novice license. (Yeah, I should upgrade now that it's so easy) I was wondering if anybody has installed any gear in their Z3. If so, what type, and did you encounter any problems with the electronics?
