ARRL 10m contest predictions

ARRL 10m contest is this weekend. I have created some short and long path propagation predictions from Northern California for the weekend. I used HamCap & SSN 30 for these simulations (that’s what IonoProbe just gave me as effective SSN).

Briefly, the operating plan could be this:

  • 00-02Z: VK/ZL/Pacific, maybe JA until 01Z
  • 0200Z: NCCC rally on CW (28040)?
  • 0230Z: NCCC rally on SSB (28400)?
  • 0300Z-15Z: go to bed, or do something else
  • 15Z: start working South Americans
  • 16Z: check for VU/9Y/HS/9M for long path opening, if not… work South Americans. Skew path to Europe by pointing antennas to Africa/South Atlantic?
  • 17Z: check for VU & Middle East long path, if not… work South Americans & ZS. Skew path to Europe by pointing antennas to Africa/South Atlantic?
  • 18-19Z: check for long path for Northern Africa, Southern Europe (EA/I), and keep working for South Americans (by now they must all be QSO B4?) & ZS. Skew path to Europe by pointing antennas to Africa/South Atlantic?
  • 20-21Z: check for long path for Northern Africa & Southern Europe, short path to South America, ZL/VK & ZS. Skew path to Europe by pointing antennas to Africa/South Atlantic?
  • 21-00Z: short path to South America, ZL & VK, maybe JA after 23Z. Skew path to JA through South Pacific?

Also, look for daytime (or 24h/day?) Sporadic-E openings to midwest and south-east USA — and probably elsewhere in USA/Canada, too. Also, meteor scatter is possible 24/7… just remember to talk/send code really fast.

Complete maps can be found here. My personal plan is to operate from W6YX (at least few hours on Friday night).

    You left out some likely (or at least possible) openings that we can exploit from W6YX.

    From about 16-21Z we might be able to work Europe by pointing at Africa/SouthAtlantic and running high power into an efficient low-angle antenna. We can then take advantage of the skew/backscatter path from the South Atlantic into Europe.

    Similarly, while we are working into the Pacific around 21-24Z we may work JA and Asia by a similar skew/backscatter path.

    It is always interesting to try pointing one antenna on the direct path, and another on the skew path, and switch back and forth …
