SB-220 Troubleshooting

[Maury Guzick]

What's the swr measurement between the 220 and the exicter? Are you
using an antenna tuner on the exciter? What is the output power showing
on the exciter into the 220 on those freqs that run low? Is the plate
dip in the right place on the 220 for the band you are on?

You may be off tune on the input matching coils in the 220. Your tube
rig could compensate with its output tuning, but this may not be so with
the newer rig.
