One detent notch adjustment on the clarifier cleared that up......

I have the NE an SW EWE antennas tied together and above ground at the "normal" terminations.

NE EWE 11:1 transformer feeding the modified HD1420 VLF converter and SW 11:1 transformer transmission

line terminated in 100 ohms in the shack.   Neat Stuff, WSPR-15 seems to be somewhat drift tolerant.....
