Many thanks to Henry (K4TMC) who notes that the AT On The Air Day is tomorrow: Saturday, October 2, 2021. For full details, check out the AT On The Air website. I’ve pasted the announcement below:

Appalachian Trail (A.T.) On The Air Day
Saturday, October 2, 2021
1200-2100 UTC (8 am-5 pm EDT)

In celebration of the 100th anniversary of the Appalachian National Scenic Trail, licensed amateur radio operators are invited to take their two-way portable radios to the trail on Saturday, October 2, 2021, for an on-the-air get-together. The goal is to contact other amateur (“ham”) radio operators either along the Trail or elsewhere in North America (or beyond) and to showcase our amateur radio hobby.

This is an impromptu activity and is not sanctioned or endorsed by any national or regional organization. It is not a contest, it is a get-together. Participants should read the Guidelines page for more details. We welcome participants from SOTA, POTA and WWFF. No awards will be issued, although a Summary Report will be published on this website afterwards to gauge participation levels and acknowledge the participants. This is intended to be a fun event !

Stay well & 73!

BREAKING NEWS: In accordance with an opinion by AT Conservancy, the Appalachian National Scenic Trail consists of “the A.T. footpath and designated viewpoints, shelters, campsites, water sources, and spur trails linking these features” — in other words, part of the white blazed main Trail, or the blue blazed side trails to shelters, campsites, summits, etc. This is especially helpful to POTA activators who need to be within 100′ of the Trail. POTA also accepts activations from trailheads along the national trail.
