Your looking at 3830 Score Rumors (link) screenshot and I enjoy publishing my raw score.

CQ Contest Digest publishes all the raw scores submitted to the 3830 list (link) at Contesting The Sport of Amateur Radio (link). If I recall correctly, many contesters still show up on 3.830, to discuss their scores and highlights. This is a longstanding tradition going back to the legacy days of RadioSport.

I enjoyed operating the Top Band at the monster wavelength using my sub-optimal antenna system and 50 watts of ham radio fun. My antenna tuner did not sizzle bacon but I sure had a sizzling good time. I almost achieved Worked All California (WAC) missing only LAX, ORG, and SDG. And I did not hear any King Henry Sixs this time around as the PAC multiplier eluded me.

Band conditions remained much of the same however who cares. The idea is just operate and let the world beneath the ionosphere know that ham radio is the best bacon in town.

Turn on, tune, operate.

Read comment (link).

Sweepstakes 75 fires up the ionosphere in a few hours to the cheers of stadium Earth fans. This is is the moment when preparation meets performance. Antenna systems checked? Transceivers checked? Contest logging programs checked? Family schedule squared?

Thousands of ham radio operators from all across the United States and Canada will propagate the toughest exchange known to RadioSport.

Memory Jogging.

  • Precedence is power level for example A is Alpha = low power up to 150 watts of output, B is Bravo = greater than 150 watts of output and Q is Quebec = 5 watts or less of output. Read rules (link) for greater detail.
  • Check is the last two digits of the year one is licensed for either the operator or station. Be very clear when transmitting check.
  • Write a post-it note if precedence and check are confusing. Post the note below one's computer screen. This procedure really makes the difference when an operator needs a precedence or check repeat.


Verify your ARRL section before Sweepstakes. My section is Santa Barbara in the state of California. Not all states have sections like California, Washington, Texas, or Florida.

The most important suggestion from KA3DRR LowPower, LowProfile RadioSport Contesting At 50Watts? Have a lot of ham radio fun this weekend!

TABLE 1. Band Summary [Blue = Qs] [Red = Time] [Yellow = Moves]



TABLE 2. Three dimensional presentation of TABLE ONE.
Percentage of Qs per Band.
  • 160m produced 0% of total.
  • 80m produced 11% of total.
  • 40m produced 53% of total.
  • 20m produced 35% of total.
  • 15m produced 1% of total.
  • 10m produced 0% of total.
Observations.

  • Level 4 (L4) low-power, low-profile sub-optimal antenna at sub-optimal height draws heavily from contest time budget when searching and pouncing (SP).
  • SP technique is expensive in terms of producing score profit per band.
  • Forty meter data validates L4 signal strength that is less movement, less time between moves, and greatest rate of return (n=53%) using CQ technique (see TABLE 1).
  • Stations recycled at a faster rate on 40m versus 80- or 20m.
  • Eighty meter data suggests least Q-production versus percentage of time and movement.
  • Twenty meter data suggests a near positive return on time and movement per Q.


Notes.
  • Improve personalized band mapping technique.
  • Improve station weakness.
  • Increase SP efficiency.
  • Focus on band strengths.

I reflected on Sweepstakes 75 and my after action report is ready

After Action Report.

Operating an Level 4 (L4) contest station teaches one the value of strategy, listening, and goal setting. And Sweepstakes is an excellent ground to refine one's contesting skill set. Such skills like copying CW, calling CQ, or searching and pouncing (SP) are continously refined using patience, tenacity, and perseverance. Perhaps no other contest like Sweepstakes pushes the envelope of one's operating expertise?

Cycle 24 produced sunspot number 1007, both the A- and K-index remained stable throughout, and the low bands like 160-, 80-, and 40m demonstrated score profitability. Low band propagation on 40m remained stable and viable throughout Sweepstakes. I took advantage of 40m sunrise and sunset grayline enhancement into Q-markets like California, Washington, and Arizona.

However high bands like 10-, 15-, and 20m especially 20m generally demand a different strategy. That is, until Cycle 24 sunspot production increases and the high bands like 10- and 15m respond accordingly.

Per Band Strategy.

Current sunspot production is not viable enough for calling CQ as a strategy difference maker. And 15m like other bands was SP-only as most Level 1 (L1), Level (L2), or Level 3 (L3) stations would eventually migrate. I basically spun the dial working only 1-Q and that Q-market space was the Pacific on 15m.
