[Amps] SB220 changing SWR in bypass

[Carl]

The SB-220 will show increasing VSWR in bypas with increasing frequency due 
to the antenna relay having some inductive reactance.

A 30-33pf 1000V COG/NPO disc cap will get it down or you can use a mica 
compression trimmer to get it perfect. Ive used the cap method for many 
decades even on 6M.
