2023 September general meeting... In-Person?
Posted by Jim KN6PE, 8 Jul 2023
Its been more than 3 years since we had one of our traditional CARES in-person general meetings. I think we are all missing the interactions that we had with each other as well as the chance to do some live show-n-tell of the latest radio, antenna, or field technique.While I think its time to give it a try, the post-COVID hurdle is now finding a room that we can use that is relatively central to the City, and free. Ken KI6SYY is working with Cupertino Parks and Rec to see if we can secure a room in Quinlan Center in a way that does not require any night $taff. This is the current holdup. As soon as we know, we will get the word out to the group.
2023 Field Day was fantastic !

Posted by Darryl KI6LDM, 24 Jun 2023
For field day, you either have great weather or great propagation. We had great weather and what a day we had!This year’s CARES 2023 Field Day was fantastic to say the least. We did very well for the score (see below) and had a wonderful turnout from 19 CARES members who came out and helped make this year’s event a success!
We operated three HF stations using ONE hex beam antenna running on three separate bands. We also had the 2 of these HF stations logging on laptops that were networked together using the N1MM Logger+.
Along with our operations, we had over 20 community visitors and plenty of official visitors including Cupertino's OEM Emergency Manager, Cupertino City Council members, Kristen K6WX / ARRL Pacific Division Director, James NV6W / ARRL Area Section Manager, and Andreas K6OTT / SCCo Acting DEC.
Our score of 1,618 points was excellent for 5 hours of operation! In fact, this is the highest score we have seen. Nice job everyone!!
Plenty of Rain... are we ready?

Posted by Jim KN6PE, 2 Mar 2023
If you missed tonight's topic on Disaster Communications by Steve KK6FPI, then you missed an excellent presentation.While we have been waiting for the "big one", the Bay Area, and Cupertino, has experienced its share of different events that remind us why we got into Emergency Communications in the first place. The recent rain has caused spot power outages and fortunately they have have been quickly resolved. But, what if they persisted for hours? Or days? Getting ready for a loss of communications and other problems is what CARES is all about.
Field response beyond Cupertino
Posted by Jim KN6PE, 25 Feb 2023
Saturday turned out to be a busy morning for Cupertino Amateur Radio Emergency Service (CARES). Twelve CARES volunteers responded to a Santa Clara County communications exercise where they practiced voice and digital message passing, emergency communications management, and cross-jurisdiction coordination by staffing positions at Cupertino’s Public Safety Communications vehicle, County EOC, and at a Mountain View field response.A total of 36 volunteer hours were logged for that morning. Thanks to all members for a terrific turnout.
