Since I don't have too much time, I have combined my hobbies and am flying model planes on 6 meter R/C. I would like to know if much design/modification is done to the equipment. Recently I bought some used ACE R/C equipment and have had good results with it. The design is somewhat dated, but I can get all the diagrams, parts, and help with no trouble from ACE. This is different from the other import units which charge $5 for a 50 cent control pot. Also I am eyeing the new computer controlled transmitters, but the $500 plus price is out of my league. Any homebrew ideas in this direction? Where do I look? The Ham mags have very little on the subject. Does anyone know where I can get Plessy ICs and data sheets from? The back-of-the-mags ads suppliers don't seem to carry them. Finally, anything good or bad about ACE products? The people around here seem to think they are quite good. The only mod I have done so far is to change the throttle so that the trim only affects the idle and not the high end. Thanks is advance.

THE AUTHOR OF THESE BULLETINS HAS CHARTED THE WWV SOLAR FLUX, A INDEX AND K INDEX MONTHLY SINCE 1974. THESE CHARTS SHOW CONSIDERABLE SIMILARITY, PARTICULARLY IF DRAWN SO THAT 27 OR 28-DAY INTERVALS LINE UP VERTICALLY, MAKING THE SUNS ROTATIONAL PERIOD MORE OBVIOUS. A SERIOUS FORECASTER WILL KNOW THAT THE ROTATIONAL PERIOD OF THE SUN IS NOT TOTALLY RELIABLE, HOWEVER. OUR SEPTEMBER AND OCTOBER CHARTS SHOW A TYPICAL RECURRENCE IN OCTOBER. AN EXTREME DISIMILARITY IS ALSO PLAIN TO SEE. A SECOND PEAK, IN THE OCTOBER CHART, COMES UP DIRECTLY ABOVE A DEEP VALLEY IN THE SEPTEMBER ONE. NOTETAKING IS ALSO USEFUL, ESPECIALLY WHEN A NEW ACTIVE AREA APPEARS, AS IN THE PAST WEEK. THE RARE ALIGNMENT OF THE SUN, EARTH AND MOON MENTIONED LAST WEEK, APPEARS TO HAVE BEEN RESPONSIBLE FOR VERY MARKED CHANGES IN THE PROPAGATION PICTURE IN THE PAST FEW DAYS. MORE CONVENTIONAL PROPAGATION APPEARS LIKELY FOR THE FORECAST WEEK. AMERICAN SUNSPOT NUMBERS FOR OCTOBER 12 THROUGH 18 WERE BETWEEN 169 AND 236 WITH A MEAN OF 205.7. AR -- Gary W.

Would any of you care to post explanations of how these wonderful things work? I'll summarise if there's interest.

The OES Emergency Operating Center position was established at 18:15 with two operators: a command net and a resource assignment net. About a dozen mobile stations were deployed to assess the damage to roads and services within Sonoma County. By 19:30, it was clear that this county had minimal damage, and the net was turned over to traffic with bay area stations. The California Department of Forestry Volunteers-In-Prevention (CDF-VIP) radio net was assembled (with many of the same RACES operators) and they worked throughout Tuesday night to set up radio links with amateur CDF stations in the Santa Cruz mountains. These hams carried emergency requests as well as health and welfare traffic until the net was closed at 19:00 on Saturday night. In addition, they passed traffic on the Northern California UHF linked repeater system (440.5 MHz), which was primarily used as a link between the state OES headquarters in Sacramento and OES and Red Cross stations in the affected areas. Some Sonoma County hams also traveled to Alameda County to act as communications resources for the rescue base set up at the I-880 collapse. All told, I thought the traffic was fairly productive and organized once the initial logistics were worked out. There was a dose of confusion, but I think it was small given the conditions. There was, in my opinion, too much non-willful interference on 2m from stations passing unimportant traffic (ie chewing the rag) on or near important frequencies. Also: a high speed digital net (de N6GN) and the appropriate end stations would have been neat to see... -mike ********************************************************** Mike Weihman n1dje: RACES, CDF-VIP mikew@hpsadmjw.hp.com mikew%hpsadmjw@hp-sde.sde.hp.com HP Signal Analysis Div.

(The ultimate Internettish thing would be WAD, Worked All Domains, but domains are created far more often than countries.) To invent some rules: 1. Messages exchanged via bulletin boards don't count: the messages must be exchanged via mail. It's perfectly ok to post CQ's to bulletin boards, but there must be two- way communication via mail to qualify as a contact. (If this game gets too popular, we may need to set up a separate bboard for it, lest INFO-HAMS/rec.ham-radio become an unusable pileup!) 2. In lieu of signal reports, QSL messages should include the text AND HEADERS of the message being replied to. This provides propagation information, such as the number of relay stations and the number and kind of mail protocols involved in the conversation. 3. A completed contact should be a message that looks like this: j From: Ed j To: Faraway-Joe e From: Faraway-Joe e To: Ed x From: Ed x To: Faraway-Joe x I saw your CQ in INFO-HAMS; here's a response from x Burlington, Massachusetts USA. e Thanks for the response Ed, I'm in Farawayville, e Neverneverland. j Here's your confirmation, Joe. The message marked x is an initial call, it doesn't count (unless you want to play by SWL rules, in which case it counts for Joe.) The lines marked e (with the included lines marked x) form a completed contact for Ed: it's proof positive that he communicated with Joe. The lines marked j (with all the included lines) form Joe's completed contact. The actual format (order, indenting, etc.) of the information doesn't matter. 4. Of course, you can include whatever other information you want in your messages, like your rig (Sun-3/60 w/8meg or whatever), other hobbies/interests, weather, latitude/longitude/altitude, whether you're operating from the home or work QTH, etc. So, CQ IDX (Internet DX) de Ed@Stony-Brook.SCRC.Symbolics.COM, in Burlington, MA USA! ------------------------------ Date: 24 Oct 89 18:16:40 GMT From: eru!luth!sunic!tut!kannel!huopio@bloom-beacon.mit.edu (Kauto Huopio) Subject: Is there any DXing or media-oriented mailing list around ? Is there any kind DXing or media-oriented mailing list around? I think that rec.ham-radio is not a very proper place to publish programme schedules and other such information.. I might be interested in putting up such mailing list, if there is anough interest?

The Klystron, a Varian VA-802, now resides at the shack of Al Ward WB5LUA and has a small plaque on its magnet commemorating the feat. It is used with great respect regularly. Sigh. The list of the pioneers who have joined the ranks of the Silent Keys is rather staggering, indeed. Just saw some pix at our most recent Rochester VHF Group meeting of Mel Wilson, W2BOC and his station, describing some of the methods he used to predict VHF propagation enhancements- especially Aurora, years ago. 73, Dave Hallidy KD5RO ------------------------------ Date: 23 Oct 89 23:49:26 GMT From: portal!cup.portal.com!HAVANAMOON@uunet.uu.net (Havana - Moon) Subject: Numbers Transmissions For the most fascinating Numbers story in the past 25 years, see the November issue of Umbra et Lux.
