    When I arrived back in Florida for the winter, first thing I did was stack 
my 6 M beams. When I go to operate I find my 1.1:1 match had moved to 51.8 Mhz. 
after fooling around with the antennas I eventually went back to the original 
single and the SWR was still at 51.8. It turns out the amplifier is causing it 
(in bypass mode) I remove the SB-220 (converted to 6M only) and the 1.1:1 is at 
50.1 again. Any ideas what could move my resonant point 1.7 Mhz?. It was fine 
when I left in the Dick NY1E
