The 1 February, 1996 meeting of the SBMS will have Joe, WA6PAZ leading a primer on Gunnplexers and rigs for the beginner. See you 1930 hours local at the American Legion Hall 1024 Main Street Corona, CA.
Last Meeting- There were quite a list of personal preferences in books discussed by the attendees.
A list will be provided later in this edition. The business of moving meeting locations is still being discussed without a good replacement for the Corona American Legion Hall and its ability to serve our needs. The parking lot patrol apparently has been effective and needs to continue. Thanks to those who do the checking. Dick, WB6DNX brought in some more copies of the wideband FM gunnplexer reprints. Those interested need to contact Dick. Interest in the old SBMS Handbooks was raised and Bill, WA6QYR will bring in some to see what the members wish to do. Dave, WA6CGR and Eric, KD6GLP will be assembling the SBMS Homepage as a place for information about microwave.
Those wishing to send material need to prepare it in ASCII test and sent to firstname.lastname@example.org. Dave, WA6OWD solicited goals for the 1996 SBMS. Some of the ideas brought forth were: get every one active and on 10 Ghz or 5 Ghz; bring in more rigs to look at construction, show and tell; plan weekend tune up sessions- WA6CDR, WA6OWD, and other have shops with equipment; an antenna measurement/picnic some weekend; power and frequency measurement meetings. There was discussion about resending the SBMS letter to ARRL about some changes to the 10 Ghz Contest. It would appear that there are those in other parts of the country that move say 5 miles north and then 5 miles east to make the next QSO location- not quite the 10 miles in one straight line from the last site as intended by ARRL. Wideband FM and narrowband SSB were proposed as being two different modes. Hours of the contest were desired to include an early morning period where over land enhancements could be used.
27 people present.
New Member- Matt Mendenhall, KE6ALM from Norwalk, CA- welcome.
24 Feb. SBMS dinner Cask and Cleaver in Cucamonga 6:30 meet, 7:30 eat. Eric, KD6GLP needs a head count at the meeting or call 909-899-3092. We will be ordering off menu. Gratuity will be added to the bill.
7 Mar Chuck, WA6EXV Transmission Lines and the Smith Chart revised.
4 Apr. Wideband FM 10 Ghz tune up party for those with gear ready to try.

6 June Chuck, WA6EXV Noise figure Measurement session
8-10 June VHF QSO Party
4 July- moved to???
3-4 Aug. UHF Contest
Equipment- Ed, W6OYJ brought in an amplifier model WBA-6 from Electronic Rainbow 6254 Lapas Trail Indianapolis IN 46268 317-291-7262 which reported to have 20 dB gain 1 Mhz to 2.5 Ghz. 2.8 dB NF (the plot shows 6 dB gain at 2.5 Ghz). Interesting broadband amp for the shop. Used a MAR-6 MMIC.
Ideas- Eric, KD6GLP will be taking a college class in printed circuit design soon and is looking for things to build. He has to do the layout, negative and etching. A couple of boards will be built. Contact him at 909-899-3092.
January VHF Contest- There was lots of discussion on the liaison frequency to be used. Generally the Santiago repeater 448.325 pl 141.3; 144.2 Mhz SSB for Jack in Mexico; 144.33 Mhz FM for San Diego. Saturday afternoon was when most were going to be out and about and on 10 Ghz.
Other microwave bands were reportedly to be active too. Next month, we'll report what happened.

From: "Robert E. Munn" <email@example.com>
Today I received a letter from the ARRL written by John Hennessee, KJ4KB, their Regulatory Information Specialist. He apologized for the delay in response to my November letter via Emil Pocock, W3EP. The comments are as follows:
" I am pleased to hear that you and others are experimenting with a 10 GHz repeater. One of the basic purposes of the Amateur Radio Service is experimentation. I can only see one problem with the set up you mentioned. Since it involves linear translator operation, the method of identification comes up.
The repeater must be identified properly on all frequencies which it operates. If you can be sure that all users will do that, there's no problem. Otherwise, you need to devise an identification method for all of the frequencies within the bandpass. 73. "
So if we follow the method used for the amateur radio linear translator satellites, then we should be ok. That method involves one or two continuously operating beacon/telemetry signals within the bandpass, which identify the satellite station callsign (the translator). The stations which transmit through the satellite translator identify with their own callsigns and those of the stations being contacted....not the satellite's callsign. As we already have an identifier beacon within the bandpass operating continuously, we seem to satisfy the rules. Our translator operates with an offset frequency of .00001 Hz. If you can disprove this, let us know how you did it.
73s from Ed, W6OYJ
P.S. We must still observe the ARRL Contest rules which forbid counting repeated QSOs for contest credit!!

SUBJ: NEW CALIFORNIA BILL AB 104
Reprint from World Radio (Newsfront) Page 7. February 1996 Issue. CC&R;'s Cannot Ban Small Antennas
California governor Pete Wilson has signed Assembly Bill 104 into law that voids and makes unenforceable land use Conditions Covenants and Restrictions, that prohibit the installation or use of video or television antennas. This includes satellite dishes measuring up to thirty-six inches in diameter.
AB 104 does give associations the right to reasonably restrict or regulate such installations, but directs that any application for an installation must not be willfully delayed. The new law even allows the award of attorney's fees for the prevailing party in an action to enforce compliance with the bill.
AB 104 was written by Assemblyman Dan Hauser and had heavy backing from Pacific Telesis.
California hams should not expect to see an announcement of AB 104 in their homeowners association newsletters. Most homeowners associations probably hope that hams never hear about the new measure. As stated earlier, AB 104 covers only small antennas designed for receiving television signals and satellite TV. While you might get away with a 2 Meter beam, a tri-band array will definitely be subject to challenge.
ARRL PACIFIC DIVISION UPDATE- FEBRUARY, 1996 by Brad Wyatt, K6WR, Director, Pacific Division, ARRL 18400 Overlook Rd. #5, Los Gatos CA 95030-5850 (408) 395-2501 (Phone and FAX) Packet: K6WR@N0ARY.#NOCAL.CA Internet: K6WR@arrl.org
The Second 2.4 GHz Repeater in the Pacific Division is on the Air:- Over the holidays, K6PRK/R went to the top of Black Mountain in the San Francisco Bay Area. It is at 2800 feet and 60 feet above the terrain. There are 2 repeaters linked together, 1.2 & 2.4 gig. The frequency for the 1.2 is 1284.850 (-12 MHz), and the 2.4 is 2424.850 (-20 MHz). The coverage for both repeaters is impressive. You can work the 2.4 gig repeater from Los Positas College in Livermore with 100 milliwatts! Coverage is very good throughout the Bay Area. We had a magnificent team effort to get the repeater built, tested and installed. For more information, contact Dan Smith, K6PRK, at email firstname.lastname@example.org.
New Amateur Radio Station at the National Weather Service in Monterey, CA:- The Monterey Peninsula Amateur Radio Emergency Service has established a voice and digital station at the NWS Forecast Office in Monterey, California. During communications emergencies this station will serve as a distribution point of weather data utilizing Amateur Radio frequencies and the existing San Francisco Bay Area Spotter's Network. As an experiment, the station is currently listening on 144.93 Mhz for 1200-baud signals and on 145.71 for 9600-baud signals. Connect to NWS and you will be into a full service BBS. Connect to WH6DT-4 for keyboard-to-keyboard on 1200 and WH6DT-7 for keyboard-to- keyboard on 9600. For more information, contact Greg Pool, WH6DT Phone: 408-649-6790; email: email@example.com; packet: wh6dt@k6ly.#cenca.ca.us.noam.
Pacific Division and ARRL WWW Home Pages:-- Through the diligent efforts of Alameda County ADECs Randy Foutch, KE6HCI, and Paul Carlin, KE6NVU, together with a dedicated band of associates, the Pacific Division Home Page is now "on the air." It can be found at http://www.pdarrl.org/ . In addition to a great deal of information on the ARRL Pacific Division, it contains links to other worthwhile pages, including the ARRL Home Page. The ARRL Home Page can be accessed directly at http://www.arrl.org/ , with links back to the Pacific Division Home Page and other sites. Give the Pacific Division Home Page a look! Many thanks to Randy, Paul, and their colleagues, for their hard work.
Telecommunications Reform:- Telecommunications reform is currently one of the key topics in Congress. Both the House and Senate have passed differing Telecommunication Reform Acts. Apparently these bills focus on broadcast TV, cable TV, telephone service and related matters. It appears that these bills do not affect the Amateur Radio Service directly, but there may yet be surprises. A conference committee from both houses is trying to reconcile the differences between S. 652 and H. R. 1555. The conference committees have been named (in the Pacific Division, from the House, Anna Eshoo (D) CA 14th is a member). Little progress has apparently been made pending the resolution of the overall budget battle which continues as this is being written on Jan. 7. The mood in Congress seems the Washington Team continues to monitor these developments and be active on our behalf. See page 15 of January QST for additional information.
Spectrum Protection Battles Continue:- The 2300 - 2310 MHz battle is probably coming soon. There is a proposal by the NTIA to make this segment available to Land Mobile Services, but this would require "auction authority" from Congress. This authority is currently stymied by the Federal budget impasse. Unfortunately, this problem could come back very quickly after the budget impasse is resolved. NTIA has also written a letter to FCC urging FCC to issue an Notice of Proposed Rule Making for the Apple Petition which involves a sharing of the frequency allocation in the ham band at 5.7 GHz. See earlier Updates for details.
Antennas, Towers and Ordinances:- The negotiations over these ordinances continue in Fresno, Sonoma and Napa counties. Fresno appears to be a long term project into late 1996; Sonoma next event will be a Board of Supervisors meeting Jan. 24; Napa next event will be a Board of Supervisors meeting Jan. 23. Good luck! Please forward copies of all antenna, tower and related ordinances to Phil Kane, N6SP, who is collecting this data for the Pacific Division. Phil can be reached at P. O. Box 280192, San Francisco CA 94128-0192, (415) 369-7373 and firstname.lastname@example.org. Please read the article by Chris Imlay, N3AKD. ARRL General Counsel, "But I Never Agreed to That" starting on page 47 of Dec. 95 QST.
