To: info-hams@ucsd.edu I have had some experience as a commercial two-way radio tech, and as a result have recently been "suckered" into helping a friend fix his Genie Garage Door Opener. If you are at all knowledgable about these things, could you PLEASE be filled with Christmas Spirit and help a guy, whos helping another guy???? :-))) Here are some of the questions I have: (by the way,....the mech. portion of the door opener is working fine) *The receiver is a model "AR-75" and also states a freq. of "310" Does this mean that the transmitter and receiver operate on 310.000Mhz., or just within this general freq. band??? *This is an older system that uses a plastic "code key" that allows small jumpers or fingers to make contact with ground. How does changing this code effect the carrier? Is the freq. pulse modulated or other? *What is the best method to align the transmitters with the receiver? (I do have access to an FM service monitor, freq. counter, wattmeter, etc.) ANY help or suggestions you might have would be VERY MUCH APPRECIATED, and might even get you on my "Christmas List"!!! :-) Please email "jeffl@pmafire.inel.gov" Thanks again and Happy Holidays!

To: info-hams@ucsd.edu I am trying to find an adapter to connect a Larsen whip to the 3/8"-24 hole on a standard car swivel mount. Something which has a 3/8"-24 thread on one end and a 0.100" hole with a set screw on the other would do it. Even better would be something threaded 3/8"-24 on one end and 5/16"-24 (standard Larsen thread for antenna cones and springs) on the other. I'll probably just make my own adapter in the machine shop, but I'm amazed that no company seems to manufacture such a device.

The idea is to let VHF/UHF FM users know what kinds of things (good and not-so-good) can be expected if, for example, they bring a hand-held transceiver along on a vacation or business trip to the Caribbean, Europe, Asia, Australia, etc. If anyone has had a FIRST-HAND opportunity with operating VHF/UHF FM outside the continental US, please shoot me a note about your personal experience. I'd like to hear about obtaining licensing/operating permission, use of repeaters/simplex, popular bands/frequencies, unusual operating practices, bringing equipment into other countries, if social contacts resulted, etc. Perhaps I'll be able to "anthologize" several people's stories in one column or in serial form. Depends on the response. Reminder: I don't like to write the column; it's a forum for *you*! We want ARRL Members from all over the world to share your thoughts on Amateur Radio FM operating and technology.

Bill WB1BRE is the New England Division Director. Like Steve, Bill also runs a cabinet meeting a week or two before the Board of Directors meet. Bill invites his vice-director, all division appointees, all Section Managers and their appointees, the Presidents of all ARRL-affiliated clubs in the division (the clubs may, at their discretion, send someone other than the club president), and selected others. He tries to make his agenda known to these folks beforehand, so that they may solicit input on the discussion topics. If there are issues that he wants very wide input on, he sends out a division newsletter with a questionnaire (and if not enough people respond to the questionnaire, he sends his cabinet members out to clubs, etc. with questionnaires). As president of our radio club, I've attended two of the NE Division cabinet meetings now, and I can tell you that they are hardly an "amen chorus"! There are some very outspoken people in the leadership of the sections and the division, and believe me, not everyone agrees with everyone else. Does Bill listen to his cabinet? Yes, but he also lets them know what he's heard from the membership at large, and he incorporates that into his words and actions as well. Bill uses the cabinet meeting as a sounding board, as a chance to get to know the ARRL and club leadership (SMs, appointees) in his division, and as a chance to educate those leaders about issues involving Amateur Radio, the ARRL, the FCC, etc. Each of the cabinet members has his own reasons for attending. > The problem with the League structure as I see it is that it's a > one party state controlled mainly by the apparatchiki.

Possibly. It's also possible we'd get a more divided organization -- consider how well DXers and Contesters, repeater owners and weak-signal folks, CW fans and haters, etc. get along now (okay, okay, so I've been reading too much r.r.a.policy lately! I keep forgetting the Internet isn't a good cross-section of the amateur world... :-) I do know that at least some of the directors currently get input on some of these topics (digital considerations, DX, repeater issues, etc.) from the ARRL committees whose purpose it is to oversee the particular area(s) in question. If I remember correctly, reports from these committees are given at each Board meeting; I do know that Bill WB1BRE often (always?) invites the New England representatives of any of these committees to his cabinet meetings. My hope is that other division directors would do the same, though I realize that may only be wishful thinking... > I also think > it would be good if members of the field organization were also elected > by the groups they would serve, IE traffic people would select their > managers etc. This happens to an extent informally now, but I think > it should be more of a formalized "merit board" type of thing to > reduce the machine politics in the present field organization. > (Lord knows though that it's hard enough to find *any* volunteers > to take some of these jobs.) Amen to that! Volunteerism is not a popular thing these days. And I suspect that's why elections aren't held at these levels. It's tough enough finding folks to run for Section Manager...

Really, the vibration is awful. And the mounts tend to absorb more shock than vibration.

ALL of them have big access hatches (usually the wing unbolts) to get at the radio. The charging connections and such are frequently inside. So could be your serial port. Again, go for a simple computer that talks, either via a radio link or via a serial cable, to another, more sophisticated computer. Bear in mind, when you think about flying it anywhere, that you have a liability problem. You can't fly R/C, and be insured, except at an AMA sanctioned field. That means no coverage of news events. Your altitude is also limited by FAA regs, so you can't foul up air traffic.
