Muskegon Amateur (HAM) Radio Field Day 2011

This is my home town Hams. I will not be at this event. I might work field day from my QTH this year.

MCECS(K8WNJ) and MAARC (W8ZHO) Joint amateur radio Field Day 2011. Muskegon County Emergency communication Service (K8WNJ) and Muskegon Area Amateur Radio Council (W8ZHO)are having a Joint Field Day 2011 along with Kent and Otawa county ARES/RACES. The 2011 amateur radio field day will be at Grose Park and will be operating under the Muskegon Area Amateur Radio Council (MAARC) call sign ~ W8ZHO.

I would provide a link for MAARC but there web-site is down at this time for maintenance.

This is the story from the local news paper.

Local 'Radio Hams' to join in Public Demonstration of Emergency Communications June 25-26
...........................................................................................

Muskegon “hams,” with colleagues from Kent and Ottawa counties, will join with thousands of Amateur Radio operators for their annual “Field Day” event June 25-26.

The public will have a chance to meet and talk with radio operators and see the newest digital and satellite capabilities, voice communications and even historical Morse code.

There will also be public demonstrations of emergency communications abilities.

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
