KA4INM - Ron,

Yep got my interest going as well!
I really don't see or have experienced anything different.
Amp was factory set-up with 10m, only thing I can see.
The fan looks like a fan, going to take a closer look at it's mfgr when I go 
back in to do p/s upgrade.

I just cant find anything regarding such exports on line but have seen some 
other Amp Supply models on you tube as exports LK-800 etc, those offered 
additional frequency's on the bandswitch, mine only has the AUX in addition 
to 160-15m.

However as Carl posted just a piece of paper required!
Interesting though my FCC ID # does not show-up on FCC site?
