Gather your children, and grandchildren, around your radios for the annual Santa net.
While Santa is delivering presents around the world, the children can call for Santa, KD8DEG, and Santa will ask each child if they have been good little boy's and girls, and what they would like for Christmas.
Elf Radar Frank, N8UVI, will be giving Santa's location using NORAD, along with Elf Techno Dave, KC8PCL, scribing, both located at Santa's communications center at the North Pole.
You can find the "Santa Net" on the Lowell repeater 145.270 pl 94.8; also use IRLP: node 9617; & Echolink: Michigan Conference node 96170 .
The originator & Elf - N8UVI Frank
Santa - KD8DEG Tom
Elf - KC8PCL Dave
Please note the changes for the IRLP and ECHOLINK Node numbers. We have been given permission to use the Michigan Conference and IRLP nodes for the Santa Net. This enables the net to run Nationally and World Wide.
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.
