VHF/UHF Tower Up and Running

Construction has finished on the initial implementation of the new UHF/VHF tower (approximately 30 feet tall) located at the northeast corner of the station. The tower currently carries horizontally polarized beam antennas for 6 meters (50 MHz), 2 meters (144 MHz), 70 cm (432 MHz), and 23 cm (1296 MHz) topped off by a multi-band discone. A crossarm provides space for 4 vertical antennas below the beam antennas, which is currently populated with a 144/440/1296 Mhz tri-band vertical, and a 220 Mhz J-pole.

The VHF/UHF station currently consists of the following equipment:

1.2 GHz Repeater Linked to Northern California Network

Bob, W6CYX, and Pete, K6TJ, have completed renovations on the W6YX 1.2 GHz repeater on Black Mountain. The repeater, which operates at 1282.5 MHz, has been integrated into a Northern California and Western Nevada network.
Information about the system is available at http://www.w6rlw.com and a coverage map can be seen at http://members.ispwest.com/rwarmke/cyx.html. Integration of the repeater into this network enhances the emergency service capabilities of the system. At one of our meetings next fall, Bob will present a program on the 1.2 GHz system

Tay Howard Room Established

H. Taylor ("Tay") Howard, W6HD (SK) was an Emeritus Professor (Research) in the Electrical Engineering Department of the School of Engineering.
Stanford recently adopted a memorial resolution reviewing his career in radio communications and space sciences.
His estate has contributed much UHF/VHF equipment to the club, which has established the Tay Howard room in his memory.

W6QI Microwave Project Page

Frank Bauregger, W6QI (SK), maintained an updated page on various microwave communications projects of interest to W6YX members, leading off with news of a new world's record for 47 GHz communications set by him and Gary, AD6FP, in September, 2004.
