April 1st Grounding! Links

Tonights topic is grounding. Lenny will lead our discussion stressing electrical circuit grounds and their impact on safety. Also, RF Grounds will be addressed and their impact on station performance. NEC (National Electrical Code) is changing in 2005. Len has reviewed the new documents and will brief us on what is required to comply with code. Measuring/quantifying the quality of your electrical ground will be discussed. Ground rods, impedance path, and soil conductivity all bear on that. For your contribution to the net bring your questions or bring your descriptions of electrical grounding situations you've grappled with in the past. I will add links that are discussed during the net.

Ron Block KB2UYT   runs a booth at Dayton every year. Makes excellent presentations about practical application of proper methods to ham applications. Also is a distributor of PolyPhaser products. Wrote a three part article for QST in the past year. PDF's of the articles available here: Part 1,   Part 2,   Part 3

Excellent Introduction   with good pictures and graphics.

PolyPhaser Corp   This company makes the stuff the big-boys use. Their single-point grounding entry boxes are the way to go. Also published great book "The Grounds for Lightning and EMP Protection (now out of print)". You can get PolyPhaser products through many ham dealers to include AES. Interesting article

March 25th Ham Organizations Links

Tonights topic is Organizations or groups that you are in or have enjoyed during your time in Ham radio. Talk about what the groups specialty is and what types and levels of enjoyment did you get out of your time with the organization. For some examples, this could vary from a group that you multi-op with for contests, or a regular group you do drive-time with on a 2m machine, to local repeater clubs, to ARES/Skywarn groups with which you participate. If the group you are talking about has a web-presence, send along their link and I'll include it here.

As a result, the club operates two or three repeaters, has monthly meetings that offer social contact and interesting programs, fosters ARES/Skywarn activities in the area, fosters license classes and testing, puts on a Field Day, hosts an annual hamfest, and an annual social banquet. Once upon a time I helped rewrite the club constitution and bylaws to comply with state law.
