In this weekend's VOA Radiogram, the Thor 50x2 mode is missing, even though it is mentioned in the preview.Truly wretched band conditions to the East Coast precluded good decodes of the first transmission. It appears that THOR held its own, even at high speeds, but deep fades took the signal out completely.
When the MFSK16 mode ID tells you this...
Next on VOA Radiogram, THOR50x2 (~180 wpm)
...please proceed directly to MFSK64. The RSID will guide you to the correct mode.
Sorry for the inconvenience.
