Hi Ken,

Thanks for the information on your VHF mods. I was going to ask if
you measured power out of the BS170 but I believe you answered that
here. I assume 20 mW is with 9V.

There are RF power modules available that will amplify 20 mW to 7W.
At least one is in the 25 USD price class. These might be worth
looking at as a PA option.

When I get caught up on the backlog of projects I plan to buy
another U3S for VHF use. My present unit is dedicated to LF and I
don't want to mess with it.
