Except we are limited in our ERP!

Please don't use such a PA at more than 100W ERP as we caould easily lose the allocation if it is abused.

Absolutely, but its a very nice amp and cheap to build, relatively. With tiny drive capability ATM I won't get anywhere near that. It will also spur me on to finish a linear transverter for NB on 4.
