Sweepstakes Operators Needed

You are invited to join the SPARC Contesters as W4TA participates in the ARRL SSB Sweepstakes Sweepstakes Logocontest beginning this Saturday at 4:00PM. Sweepstakes is the oldest domestic amateur radio contest held, beginning in 1930.

We will gather around 1:00PM to reinstall our temporary 40M/80M dipole antenna, with operating activities starting at 4:00PM. The object of this contest is to exchange QSO information with other stations in the United States and Canada (including territories and possessions) using the 160, 80, 40, 20, 15 and 10 meter bands. While the contest lasts around 24 hours, we typically operate until we get a clean sweep of all 83 ARRL/RAC sections.

If you would like to tryout our new antenna system, learn how to contest or just enjoy the fellowship, drop by the club station on Saturday or Sunday morning.

W4TA back in Contest Mode…New Antennas Work Great

With the completion of the relocation of our Log Periodic antenna on our new tower and the erection of a temporary dipole for 40M/80M, W4TA is on the air. The tower puts the antennas up around 55 feet. And boy do they work well in combination with the Alpha 9500 amplifier. We inaugurated the antenna/amplifier combination in the CW Sweepstakes contest, the oldest contest in amateur radio. It was no effort to hold a frequency and it was fun to hear the pile ups focused on us.

Congratulations to all that were involved in raising the SPARC contesting effort to a new level.

Antenna Modeling with EZNEC

 

The program for Friday, Nov 4, will be antenna modeling, building simple models and then comparing them to more complex antennas.  Ed, NZ1Q will demonstrate EZNEC software, which offers a free demo program that can be easily downloaded.   Ed will go through how to build an antenna model and read the resulting charts and graphs for a simple dipole, a two element beam and then as time permits, an Off Center Fed Dipole and other antennas., Radiation patterns, SWR, impedance matching and effects of grounds will be demonstrated. 

Be sure to join us this Friday for a truly informative program.
