Class 5A· Mission alignment

TBARC's 2025 Field Day was the club's first fully portable battery-powered operation — ARRL Class 5A, a public field site, and the kind of emergency-prep exercise Field Day was designed to be. The score dipped slightly; the bonus paper trail nearly doubled.

Per the ARRL: 4,373 entries from all 85 sections; 31,919 participants; 1.2 million QSOs. Entries up ~1% from 2024; total QSOs down 8% as solar conditions softened the higher HF bands for many operators.

Band by band

20m phone carried the operation

438 of the 471 phone QSOs landed on 20m SSB — 93% of the phone column on a single band. 15m and 10m phone were thin; 80m was digital-only via the FT8 station. The portable antenna farm favored 20m hard.

Zero CW · the 2026 leverage point

A 5A operation with zero CW is rare at the top of the leaderboard. Every AZ club ranked above us ran significant CW — and CW counts double the per-QSO value of phone. Recruiting or developing one dedicated CW operator for 2026 is the highest-leverage move on the board.

Operators

Eight operators ran the main station

From the main-station ADIF (779 QSOs). N0SNO carried 55% of the load — heroic, but also the bus-factor risk we'll address in 2026 by spreading the operator schedule across 3-5 ops at 150-200 each.
