The 4 January 1996 meeting will have you bring your favorite "tech book" in to do a
show and tell about everyone's book. SBMS continues to meet at the American Legion
Hall 1024 Main Street Corona CA at 1930 hours local time. Bring ideas for things
that the SBMS should work on in '96 and any thoughts for rule changes in the 10 Ghz
contest. Hope you and yours had  Happy Holidays.
Last meeting had Phil ,W6HCC talk about his 3 band (2.4, 3.4, and 5.7 Ghz) rig. It
has 3 microwave bricks and two crystal oscillators (100 and 8 Mhz) mixed to form the
LO for each band. It has unique plug-in filters to select which band it is on.
Unique design, Phil- thanks for sharing. Bill, WA6QYR brought in his first 10 Ghz 
gunnplexer rig to show and tell. It has one of the original 6 mw MA/COM gunnplexers
(1978 vintage). The 30 Mhz IF control circuits are similar to those in previous
months newsletter allowing for relative or crystal lock of the gunn.  This is like
the old tube rockloc rigs of the past. The boomerang and wavemeter test equipment
were shown as items one might want to check that the rig was working and to adjust
frequency on to the contact being planned. Thanks Bill. Chip, N6CA brought in the
Small Inductor winding information enclosed from some 20 years ago. It was
originally written by Dauph at TRW from measurements done on number 24 wire wound on
various drill bit sizes to produce coils of known inductance. Chip has used it a lot
in the past years. Thanks for sharing it Chip. Another piece of equipment brought in
and passed around was a Down East Microwave weak signal source build from kit and
boxed by Bill, WA6QYR. It puts out some 10 mw on 1152 Mhz with harmonics useable to
10 Ghz. 33 people present.
Visitors - Matt Mendenhall, KE6ALM of Norwalk, Aaron Tracey, KD6UUN, David Mulvey,
KD6BZN and Carl, K6RLP all of Lancaster, and Jim Harrison, KE6YUM of Cypress.

The Northern California group is to have a meeting December 9 about organizing the
activity there.
The Inland Empire Council of Amateur Radio Organizations [of which SBMS is a part]
under the lead of Jerry Verduff, AD0A is working to get the ARRL SW Div. convention
moved to Riverside.
The SBMS move to a new meeting place is still looking for a "home". Several sites
have been visited.
Bring your plans for the January Contest to the meeting along with thoughts on
liaison frequency.
Jack, N6XQ has a new email address- jack@sisna.com.

  Activity Report from San Diego Microwave Group for 12/12/95 by Ed, W6OYJ
Art KC6UQH and Ray N6RE are getting equipment ready to do a 2-way 10 Ghz ATV QSO from
San Marcos (SD County)  to Palos Verdes, about 80 miles. They previously made it one-
way over this path.
Jim NE6O is working on his power supply and oscillator for 10 GHz.
Chuck, WB6IGP has been reviewing a copy of the December issue of the Japanese
magazine "Ham Radio". An article by Goro Obikata JA1EPK shows innovative modification
approaches of the Qualcom xcvr. Text is Japanese  but excellent pictures are in
Ed, W6OYJ reported that Jack, N6XQ indicates the orders for the Chaparral antenna
feeds may come out closer to $16 and $20 each. [ed. note see enclosed article from
Dec. Pack Rats Cheese Bits].
Tony, KC6QHP will be working on a digital video project using ethernet modems, during
his December school vacation.
Kerry, N6IZW reminded the group of our December 18 Christmas meeting at his house,
and to bring microwave white elephants (wrapped for mystery) to exchange. Kerry has
been modifying three Qualcomm xcvr main boards and plans a trip with Jerry, WA6VLF to
do some work on the mountain top X-band signal booster/repeater.
SBMS Activity Report of 12/7/95 
Ken WB6DTA was on 2 mtr from DM23.
Gordon, WB6YLI reported flat conditions working UK to France on 10 GHz.
Chip, N6CA brought in the coil data.
Ed, K6ODV nothing to report.
Stuart, K6YAZ has his 1200 Mhz antenna back up.

Ed, W6OYJ reported working on a 5 Mhz TXO for the Qualcom 10 Ghz rig. A number of San
Diego group are looking to work home to home. The group has written ARRL to get some
kind of ruling on what their 10 Ghz signal amplifier/repeater is since its input and
out put are on same frequency. Jack, N6XQ has a source of the scalar "Chaparral" feed
that works good on 10368 Mhz. Just needs a screw in the waveguide to tune it on 
frequency. $20 ship and handling with instructions.
