Folks -

Im also working on a SB221 (modified for 10) that wont load on 80 under about 3.95 mhz. I measured the resonant frequency of the plate coil and it doesnt seem to dip below 4 mhz. I looked at the bottom of the plate coil and perhaps several turns have been removed? Can someone with a 220/221 tell me how many turns are on their plate coil below the 40m tap? Mine has 10.

Dana
