Right, My AV-640 has worked the world, literally. I could spend a lot of 
time telling stories .
On 12 meters, ragchewed with N2WB op at VP6DX on 12 meters between band 
opening. I was running 100 watts SSB
Likewise on 30 and 40 I have 266 and 269 countries logged .
You just have to keep an eye on the 17 meter stub insulator at the top of 
the stub. The insulator can burn and short the stub to the main radiator. I 
think it happened here once due to accidentally loading the antenna on 160 
meters. That point on the stub became a high voltage point and the insulator 
was wet from morning dew.
Replaced the insulator and all was well again.
