Thats interesting. Before I replaced the Hayseed cap, the RF gain acted 
as I described in the previous email but now it is worse. I am going to 
put a meter on the pot to see what it might be doing. If I need one, not 
sure where a replacement can be found but may have to start looking. 
Just one of my couple of issues Im trying to work out for now.

Thanks-Bob-W0YBS
