[TowerTalk] A3 problem

[sabrams at nycap.rr.com]

Absolutely!!  I had the same problem with an A4S--just a few bugs and wet 
grass in a trap makes all the difference.  After the clean-up, it was right 
on the money.  By the way, you only have to clean the traps for the driven 
element.  73  Saul  K2XA
