Last meeting-Robin , WA6CDR filled in with a talk about the Cactus Intertie Network. Cactus is in its 25th year of operation on the 450 MHz band connecting all of California with 5 other states. In some places 2 and 5 Ghz links connect sites within the system. It is the largest continuously operating amateur network in the US. The system can be segmented for special events within an area. All 1300 members are control operators. There are some 110 radios on line controlled by amateurs. Links have an average distance of 130 miles (outside Texas, Texas flatlands have 60-90 mile links). Multiple routes allow for failures and maintenance at sites. Frequency reuse is quite common throughout the system since it covers such large geography. Cactus uses fewer frequencies than some local networks. The system allows multiple conversations to happen concurrently with everyone hearing everyone else. Thanks Robin for educating us. Bob W6SYA indicated the 18 inch DSS dishes and mounting are still available for the shipping cost (about $12 per dish) from SATMART 166 Brim Creek Rd Vader WA 98593 1-800-295-3925 or firstname.lastname@example.org. Welcome to visitors; Kerry Banke, N6IZW of San Diego; John Oppen, KJ6HZ of Stanon; Ron Hammel, KC6WLC of Lancaster; and Mel Swanberg, WA6JBD of Riverside. Dave, WB6OVZ was elected recording secretary following Eric, KD6GLP changing work schedules. Ed, K6ODV is reported doing super following eye surgery. A place is still needed for the joint SBMS and San Diego Microwave Group picnic/ antenna party. Ed, W6OYJ and Kerry, N6IZW brought in some left over equipment from the Ray Harland, W7FRA estate. Robin, WA6CDR carried in some excess 2 Ghz equipment. SBMS will be responding to the request for comments on FCC RM9259 about following bandplans.

This is a follow on to an ARRL info-server document ismfreq.txt dated back in 1992. I found in a 1998 magazine a 1996 update to the Omega Enginnering Inc. wall chart in the referenced text. The ISM bands remained the same but the amateur bands and some of the other little notes changed and seemed interesting. Also marked on chart was US Department of Commerce, National Telecommunications and Information Administration, Office of Spectrum Management, November 1996 perhaps as the source of the data.
ISM stands for Industrial, Scientific and Medical.

1850 to 1910 Mhz and 1930 to 1990 Mhz are new PCS frequencies with 1910 to 1930 Mhz being unlicensed PCS devices.
59 to 64 Ghz is now for unlicensed devices.
The noting of "non-government exclusive" frequencies might be a tag for possible spectrum grabs. Most of those frequencies were the amateur bands.
