Thursday Tech Talk Net occurs Thursday nights at 7:00pm Local on the 145.45 NØBVE Repeater. It is linked to NØBVE's 6m and 440 Repeaters.
Organizer and Chief NCS is Lenny KØSHF. By utilizing a stable of volunteer
NCS's, the topics stay diverse and no NCS gets burned out. Contact Lenny if
you have good topics for the net at
SixtCylHum (at) aol.com .
Hey! Lenny's serious! You NEED to send him net ideas and you NEED to volunteer to be net control and lead a discussion! You don't have to know alot--just lead a discussion.
May 13th NCS: K0SHF Topic:
May 20th NCS: ? Topic: ? May 27th NCS: ? Topic: ?

Whatever they were, tell us about them tonight. Also share resources that are helpful for you. Relatedly, discuss if you use Dead Bug style, if you've done homebrew Surface Mount, and what PCB techniques you like.

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.

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.
