I wondered why my spots were well off on 20m compared with other stations. I then noticed that my dial frequency was 14.0956 rather than 14.095628 which is what it is after WSPR 2.0 has applied the correction for my IC703.
What I had done was to uncheck and re-check the "CAT" box in Station Parameters. This had the effect of permanently unchecking "Enable Frequency Correction" in Advanced. The next time I moved band, I arrived without the correction being applied.
Re-checking the "Enable Frequency Correction" and pressing "Update Rig Frequency" put things right again.
