2025 Big Bunny 5K!

Posted by Steve KK6FPI, 9 Mar 2025
Eighteen CARES members (and one volunteer from Saratoga (SARA)) supported the annual Big Bunny 5K run. Members were positioned along the course to function as the eyes and ears for Parks and Recreation. CARES had a net control station at the incident command post at Wilson Park. One member functioned as a Liaison for the Parks and Recreation Leader at the Civic Center. Working with CERT members, the Cupertino Citizen Corps covered the entire 5K course. All field responders reported information about the location of the lead runner and the location of the sweep trailing the last runner. Issues pertaining to vehicle traffic were communicated as well.Thanks to our efforts, the Parks and Recreation team had excellent situational awareness of the race status.

Congratulations to the 14 CARES members who made this year's ARRL Field Day event a success.CARES treats field day (first) as a field emergency communications exercise where *nothing* works except our own antennas, radios, power, and skills to put all necessary flavors of radios on the air. This year included HF (main and GOTA), 6 meter VHF, 2 meter VHF voice, 220 VHF packet, and 5GHz Mesh networking. And then, it's a contest (stay tuned for the results)!
Special thanks to Darryl KI6LDM for his enthusiasm and organization to make this year's event happen. We hope to see you all next year!
By the way, our submitted score was 1585!
W6TDM Repeater Update
Posted by Jim KN6PE, 7 Mar 2024
These updates address the W6TDM repeater problem that CARES has been experiencing recently.1 May 2024: Strangely, the problem went away and all is back to normal. Thanks to everyone who helped troubleshoot this issue!
1 March 2024: Repeater and link radio are back on the standard antenna. The problem seems to be isolated to remote interference into the radio. Extensive monitoring is in progress.
8 Feb 2024: Repeater and link radio are currently running on a mag mount antenna. Coverage and output power levels may be slightly decreased. Troubleshooting continues.
