It is shown with one of the Senao radios in the first mini-PCI slot. The second slot and the CF card are on the other side of the board. The main connectors are on the left: ethernet, power, and serial from top to bottom. text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=how-to_access&rev=1146339155 Currently the only infrastructure in existence is a WRAP board at La Vigia and one on TvE’s water tank.

The question was whether two 802.11g radios on “adjacent” channels at the same location interfere with each other. As of this test, the diablo project runs 3 links: lavigia to diablo1 on channel 10 (2.457Ghz), wcc to diablo2 on channel 2 (2.417Ghz), and lavigia to wcc on channel 5 (2.432Ghz). The question was whether the two radios at each site interfere with each other, and specially whether thet two r… text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_01_2005&rev=1146339155 After several months of preparations we were finally able to head to Santa Cruz Island the week-end of December 3rd to 5th to install the first Diablo Link station on the island. The goal of this first phase of the project is to demonstrate the feasibility of operating 802.11 (WiFi) links at 2.4Ghz between the mainland and Santa Cruz Island using relatively inexpensive off-the-shelf gear. In particular, we wanted to establish two links: one between the club repeater site at La Vigia hill and Dia… text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_07_2005&rev=1146339155 By: Bill Talanian, W1UUQ & Thorsten Von Eicken, N6TVE SBARC reached a new milestone on July 8, 2005 when video was transmitted by mainland command from Diablo Peak, Santa Cruz Island, back to the mainland. One might say, “no-biggee” but 26 miles from the mainland at 2.4 GHz running 100 milli-watt wideband signal to the Island is significant. Attenuation factors such as normal path loss, fog, frequent thermal layers, and signal multi-path all give rise to the theory that it cannot be consist… text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_08_2005&rev=1146339155 By Bill Talanian, W1UUQ Amateur Radio is such a diverse hobby that hardly do we have one mode wherein each Amateur can talk with every other. Locally general announcements typically happen on nets, the Klix-Klix, or the Internet to reach this broad spectrum of hobbyists. By now most everyone has heard that SBARC supports and maintains the Diablo Peak Project, a high speed 802.11 circuit from the mainland to Diablo Peak on Santa Cruz Island. For those that missed the announcement on the lists… text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_09_2005&rev=1146339155 by Thorsten von Eicken, N6TVE Ready for a quick quiz? You are operating two 802.11 transmitters, one on Diablo Peak on Santa Cruz island and one at La Vigia on the mesa (the K6TZ repeater site). Both use the same power (about 80mW) and same directional high-gain antennas (about 24dBi) and both point to two receivers with identical antennas located 2100’ AMSL in the San Marcos pass area. Both transmitters send a short “beacon” packet at a 1Mbps data rate every 100ms and the receivers measu… text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_11_2004&rev=1146339155 The goal of the Diablo Link project is to bring back interesting video images from Santa Cruz islands to researchers, educational institutions, and even into your living room. We hope to combine amateur radio, computers, mountain-top repeaters, video cameras, and operational know-how into an interesting project that offers many technical challenges, ample room for experimentation, as well as exciting applications that capture interest in the larger community. text/html 2006-04-29T12:32:35-07:00 http://diablo.voneicken.com/doku.php?id=key_klix_12_2004&rev=1146339155 Since writing last month’s Key Klix article we have mostly spent our time preparing all the hardware and software needed for the upcoming deployment at Diablo Peak on Santa Cruz island. Erik Aschehoug at the Nature Conservancy is quite excited by the experiment and sees a large number of potential benefits to research projects going on at the island. He promptly invited us for a trip the week-end of December 4th which thereby has become our deployment target date.
