Hi all, I am mentoring a school in Indiana County PA that is going to have an upcoming ARISS contact. We don't have the school scheduled yet but it will probably be in early 2014. If you can provide some help with equipment, then please let me know and I will forward it on to the school. Thanks for the help. 73, Charlie Sufana AJ9N One of the ARISS mentors

SPECIAL EVENT
by Peter Portanova 16 Aug '13

16 Aug '13

Hello, This weekend is Lighthouse Lightship weekend, around the world. I will be operating at the Fire Island Lighthouse, from Fire Island, NY, FN30. The host club is the Great South Bay ARC, www.gsbarc.org. I will be using the club call sign, W2GSB/FI. The plan is to work all the amateur satellites, Saturday and Sunday, starting on the 14:23 U pass of FO-29. The operating hours will be until 4 PM, as the Lighthouse is being repaired and we must leave at that hour each day. If you like to collect Lighthouse QSL cards you will enjoy having this one, and can mail your card to my home call. I look forward to working many stations and those of you worked me at Custer Observatory, QSL cards are being printed, thank you. 73 Pete WB2OQQ

QSL cards will be routed through the Snohomish Hams Club, P.O. Box 946, Everett WA 98206. This will be my first attempt at a special event station so please be patient in case there is a pile-up.

Re: Antenna element and Boom material
by Russ Ramirez 15 Aug '13

>I am wondering about going from 1/4 inch tound elements to about 3/8 inch square >would effect the performance of this antenna. >Mike Hoblinski >N6IMF It definitely will Mike, but not in a positive/negative way per se. Let me explain. If you follow an optimized design that called for 1/4 inch round elements and substitute 3/8 in square tubing, the impedance and SWR bandwidth characteristics will change in the general sense, and these changes may or may not be desirable. I do not have the experience with LP antenna implementations that I do with Yagi or wire antennas, so perhaps there are other issues to consider. I would suspect that the low SWR points across the bands would simply shift. Changes in element diameters generally affects the electrical length, and in your example only a small amount. Russ K0WFS
