Our class · 5D

One of three clubs to run 5D nationwide

Class 5D — five home stations operating on commercial power — is a rarely-filed configuration. Most clubs running 5+ transmitters opt for Class 5A (portable on battery/generator) or 5E (home stations on emergency power). TBARC's 2024 5D filing put the club in a tiny national peer group.

Where the contacts came from

The 6m/10m WSJTX station carried a huge fraction of the digital contacts. CW activity was distributed across 40m, 20m, and 15m. Phone was 20m-heavy but with usable Saturday-afternoon 15m activity too.

Site & submission

Operating location · in memoriam

The 2024 operation ran from Jack Lunsford's 5-acre property in Flagstaff, Arizona. Jack — callsign NT7MM (formerly KD7RCJ) — was a longtime TBARC member and a generous host who made the Class 5D home-station configuration possible. Jack became a Silent Key not long after Field Day 2024, and the club is grateful for the years of friendship, the use of his QTH, and the radio operating he championed.

Entry submitted by Brandon McWhorter (KN6SEU), then TBARC president. ARRL confirmation number 272yg8cz.

73, Jack. We'll work the bands in your memory.
