Site Details

Future Plans

• Install a hAP ac2 to manage the backbone radio.
• Switch the backbone sector for one with bigger gain.

Completed Work

April, 2023

• Attempt to install new hAP ac2 failed. Whenever the device was inserted the power would fail. The immediate thought was that some grounding issue caused the problem.
• Ran out of time to reposition the antenna. A new attempt will be made at a later date.

March, 2023

• Link from ORCA to Wolfback installed and operating successfully. Still requires adjustment at Wolfback to improve quality. Switching to a narrow sector antenna might be helpful.

November, 2022

• Experiment from San Pedro failed to establish a link. We wont pursue a link from this site to Wolfback further.

October, 2022

• Put a Ubiquiti LTU radio at site connected to a sector antenna, pointing at 40°. We will experiment to see if we can establish links from ORCA, CCCC and San Pedro using Ubiquiti AF5XHD radios and 30 dBi dishes.
• Experiment (Oct 12th, 2022) from ORCA was inconclusive, but test conditions were challenging (wind and fog). A link could be established, but the signal was intermittent. It might be necessary to adjust to tilt of the Woflback sector to be 2° up to counteract the in-built electronic down-tilt.
• Experiment from CCCC established a link.
