The 5 November 1998 meeting of the SBMS will have Kerry Banke, N6IZW of the San Diego Microwave Group bring and talk about his Loran-based precision frequency reference and comparator that provides 10-12 type stability . It provides a direct reading comparator display, and is capable of accepting10.0 Mhz, 5.0 MHz, or 1.0 Mhz inputs from external frequency references.You may wish to bring your counter or other shop frequency standard to see how you compare. It helps to be on the same frequency when in the field. Hi. Kerry will also discuss progress in his recent efforts to modify some of the Qualcomm hardware for narrowband 24 GHz operation. The SBMS meets at the American Legion Hall 1024 Main Street (south of the 91 freeway in Corona, CA at 1930 hours local time on the first Thursday of each month..

Last Meeting- Doug, K6JEY had a hands on tech talk /demonstration of spectrum analyzers. There were 6 different spectrum analyzers brought in and people got to play with the knobs under the guidance of Doug. Doug explained about the spectrum analyzer being like an oscilloscope and a receiver being merged, but that the trace sweep was tied to the LO of the receiver to move across a bandwidth. The IF bandwidth of the receiver was variable using the knobs on the front panel. Preamps and filters in the front-end of the spectrum analyzer are sometimes necessary to increase the capability of the measurement tool. Several off the air signals were viewed as well as some HT generated signals. Thanks Doug for providing a educational event. Paul de Jonckheere, WB6GHK of Riverside visited the meeting, Welcome. Gary Belda, K6ENS, is a new SBMS member. Glad to have you Gary. Ed, W6OYJ had a modified Qualcomm RF Synthesizer board operating on 1152 MHz for use as a frequency marker on bands through 10 GHz to show. Apparently more boards will be available via Chuck, WA6IGP of the San Diego Microwave Group. Chuck can be contacted at 619.460.7266 or clhough@pacbell.net. 20 people present.

More 10 GHz contest comments-- I had a great time! I was using WA6CGR's spare narrow-band 10-GHz station on Sunday - August 16th and again on the September weekend. Saturday was spent on Heaps Peak with Chuck - WA6EXV, and Sunday I was roaming between Signal Hill (near Long Beach), San Pedro Harbor (see article below) and the West-end of the Palos Verdes Peninsula in Palos Verdes Estates. While at San Pedro Harbor...I selected the Los Angeles Harbor Exchange Office parking lot - a favorite overlook area of mine - that's located above and due North of the Korean Freedom Bell exhibit off of Gaffey Street in San Pedro. This facility is operated much like an aircraft control tower - where these experienced LA Harbor Port Pilot's orchestrate the passage of large container and cruise ships in and out of the LA Maritime Complex. From the time I arrived in their parking lot... popping the rear hatch of the Cherokee - setting-up the tripod, mounting the 30" parabolic dish and securing WA6CGR's spare 10-GHz station atop the tripod mounting plate consumed ~ 10 minutes effort and I was on the air making the first of many contacts from this beautiful vantage point! I must have peaked the interest of one of the US Coast Guardsmen stationed at this site... for he came out to where I had assembled this station and politely inquired '... some of us were wondering - just what are you doing...?'I proceeded to explain that I was an Amateur Radio Operator... talking with a unique group of 'Hams' who were actively involved with making as many contacts as possible within a specified period of time. Being a radiomen... he understood the concept of the Amateur 'Field Day'... and further offered '... isn't it a little late in the year for that?' I then explained that this contest was unique in that it was for contacts made at 10-GHz and up. 'Ooh, he said. That explains the microwave dish!' Right!... I exclaimed. He then overheard the call signs of both XE2/N6XQ and XE2/WA6CDR coming from the radio. He knew the XE2 prefix was Mexico... and by noting the azimuth the dish was oriented... (my lensatic compass was on the ground - underneath the tripod) furthered his curiosity. As Jack (XE2/N6XQ) and Robin (XE2/WA6CDR) repeated their call signs and grid identifiers - for dramatic-effect - I started to pan the little dish. Ever so slowly - first in azimuth then in elevation, began dipping then peaking the signal strength. I pointed to the laptop PC showing the 'To' and 'From' grids and the bearing/mileage between these locations, including an Aeronautical Sectional Chart showing the relative positions of each of our 10-GHz stations. The 'Coastie' was last seen walking back to his office... shaking his head and was heard muttering something about '... unbelievable!' -Gary Belda/K6ENS (First-time 10-GHz contester!)
