Field Day: what an event it was! This year we operated QRP in the 12A Battery category from Mora Hill in Rancho San Antonio Open Space Preserve, overlooking the Silicon Valley from an elevation of 500 feet. We had a Get-On-The-Air (GOTA) station, three HF CW stations, three HF SSB stations, three HF digital stations, and five VHF/UHF stations including one with satellite link capabilities.

Our Field Day score in 2022 and 2023 had placed us at #2 out of roughly 4,000 entries nationwide — second only to W3AO on the East Coast. This year, we were in a good position to beat our previous QSO totals. But NOAA observed a M9-class solar flare (peaking at 1301z Sunday morning) which triggered a R2-moderate radio black-out. The sudden drop-off in signals caused some of our site’s operators to wonder if their rigs/antennas were still working properly. Needless to say, we came in a bit below last year’s QSO totals, but still with impressive results: 2,426 contacts and a preliminary total score of 23,690

Antennas on Mora Hill this year included a 4-band (10/15/20/40) yagi, a 2-element wire yagi on 40, and 2-element quads on 10, 15 and 20. In order to minimize interference between the CW and digital stations, Bobby located the digital tent’s triband yagi and dipoles about 200 feet from the rest of the site. The digital team was able to avoid long runs of coax by installing the digital RF hardware for both of their stations in the van and then running 200 feet of Cat5 Ethernet cable to the main site where the digital tent and terminals were located.
