QRP in the Park

Hi Everyone,
We will be firing up the grills and putting our amateur radio skills into action as we kick off our first QRP IN THE PARK for 2012! If you ever wanted to work low power portable on CW, SSB phone, or the digital modes with HF, UHF, VHF bands; we invite you stop by and operate with us. All operators are encouraged to operated from battery for this event. No generators will be provided.
Where? HELDER PARK
3751 104th Avenue
Holland, Michigan
When? SATURDAY MAY 26TH – 3PM TO DUSK
Note: This event is weather permitting and will cancel if severe
weather is expected for the area. Please monitor this reflector and 147.06 K8DAA
repeater the evening of the event for any changes of times or event cancel.
See You There!

---------------------------------------------------------------
In addition to the fun starting at 3 pm, there will be a few 15
milliwatt transmitters hidden within the park. You are more than invited
to find them. There is no competition with this hunt, just the fun of
finding these little boxes.

Bring your own equipment, or there will be gear there to be loaned out
for you to hunt within the park.

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.
