Repeater Information

Santiago Peak - WA6SVT

Mike WA6SVT and Dave KA6DPS went to Santiago Peak 3-19-95 to install the 10 GHz filter and reset the computer I.D.er. They also set the video and audio levels for the 2 GHz and 434 MHz machines. They will have to make another trip to remount the 10 GHz antenna. When they put the filter on, they had to move the antenna and now Mike KC6CCC can not get in on 10 GHz. So far Mike KC6CCC is the only one on 10 GHz with 100 milliwatts and a 3 ft. dish, but other people are working on it.

Blueridge Mt. - WB6VVV

Mark WB7AJC rode his Motorcycle up to Blueridge and then walked 4.5 miles from the highway in snow up to his knees with 100 lbs. of tools. The 434 antenna had broken in half. He climbed the tower and hooked up a spare 434 receive antenna that was at the repeater site. The repeater now is working but we will need to buy a new antenna. I hope we can wait until the snow melts so we can drive up to the site. Thank you Mark from all of us.

Coming Events

ATV Demonstrations Generate Excitement

"IT'S GREAT TO SEE THE EXCITEMENT OF HAMS EXPERIENCE A NEW MODE OF OPERATION, ESPECIALLY ATV" says Roland Hoffman, KC6JPG as Amateur Television demonstrations are making a big impact to the many hams who have been curious about this fascinating mode of operation, but didn't want to invest to see if this mode is right for them.

With the help of the many ATV'ers, especially the members of the Amateur Television Network, ATV demo's made a strong impression to interested hams (and would be hams) at many different Amateur Radio Clubs in the Inland Empire.

Since July of 1994, Roland has been introducing ATV (and ATN) at the Riverside Amateur Radio Club, in the City of Riverside; Tri-County Amateur Radio Club, in Pomona; Corona-Norco Amateur Radio Club, in the City of Corona; Golden Triangle Amateur Radio Club, in the city on Murietta Hot Springs; and the OMIK Amateur Radio Club during their national convention in Las Vegas Nevada. All transmissions were sent to the WA6SVT Santiago Peak repeater with the exception of OMIK demo as the KB7BY Mt. Potasi repeater was utilized.

In the future, Roland is planning a trip to the Bakersfield area to spark some interest in support of the Mt. Breckenridge System.

Special thanks goes to Moody Law-WQ6I for his help & support for the Tri-County Amateur Radio Club meeting and Ed Cooper-AC6BO for his support at the Corona-Norco Club and at the Golden Triangle Club. A big THANK YOU goes to all ATV'ers for your "ON THE AIR" help and support in which made these demonstrations informative, educational, and FUN!

If you are interested to have a demo set-up for your radio club or group, contact Roland Hoffman-KC6JPG at 909-356-2021, and he will put your group ON TV (ATV that is)!
