2012 Appalachian Trail Ham Radio Survey: The goal of this survey is to determine ham radio coverage all along the Appalachian Trail and develop a list of all useable
repeaters and the reliability of APRS communications. The trail will be covered in
sections beginning in Georgia mid March, Tennessee/North Carolina early April, Virginia in April and early May, then Maryland, Pensylvania and New York in late May. After a month break, the survey will resume in Connecticut in July on to Maine by the end of August. We already
completed a section of the trail during the annual Hike Across Maryland. This is mildly related to our
Annual AT Golden Packet Event.

Sections so Far: The following sections have been hiked. Even if you have hiked it in the past, your track may still be on file. All you have to do is hike the trail with your APRS radio and tell us the DATES and TIMES and the CALLSIGN and we can add your section:
Hike Planning: The only need is for day hikers or weekend hikers to cover just their local length of the trail and to carry an APRS HT. Their coverage is automatically collected by APRS.FI. They will also be encouraged to make notes on voice repeaters and Echolink/IRLP links too. The only AT repeater guide I can find is 15 years old (see guide). There is also an IRLP node Map by KD3SU See google map and an AT IRLP list.
THROUGH HIKERS: The timing of the survey matches the annual northbound treck of a hundred or so thru-hikers that are attempting to hike the full 2175 miles. In this regard, we are happy to report the position of any through hikers and their status to the APRS map for friends and family to see on APRS.FI. In this case each APRS hiker is encouraged to hike North to South on his leg so that he encouters the maximum number of through hikers. You might want to prepare a small Ham Radio APRS handout to give to them when you ask for their trail name to let them know what we are doing. Please turn around and walk with them while chatting so as not to slow their progress. Use your HT to send a MESSAGE-OBJECT.
Logistics Support: The original idea to assist Ham radio hikers, was to have a ham radio
chase logistics vehicle (SAG car) that would be available and provide one-way travel from the
hikers car to the start of his hike back to his/her car. In this manner, single hikers are accomodated.
The car would be moved from south to north, allowing the survey hikers to hike north-to-south back to their
cars and in this manner meet in passing the maximum number of thru-hikers. At this time it is not clear
if this sag vehicle is available. The maps
below can give you an initial idea of the trail in your area. Do not be confused
by the 45 degree tilt of these maps from North. That makes the trail lay out pretty
well on a map from top to bottom.

SAG Car Logistics: [This SAG car idea is on hold as we have lost one of our main hikers] The origional plan called for the following day hikes on the day indicated to get the logistics car to the next location. The present location of the car can be seen here. There are several ways that volunteers can manage the logistics to do this.
A1: Single person drives to SAG car, drives it to next location and hikes back.
A2: Couple drives to SAG car, both drive their car and SAG car to next location and they are free for rest of day.
B1: Single person drives to next point in PM, picks up ham thru-hiker, drives back to SAG car. (timing critical)
B2: Single person drives to next point in AM, meets Ham-hiker in SAG car,
then drives hiker back to start. (timing critical)
Signups for Logistics: The following legs shown in Bold are still open. We are only beginning the planning process. But the following will give an idea of how it works.

Annual Ham Radio Golden Packet Test: This Survey is not directly related to the annual Golden Packet Test but it shares a lot of the same people and interests. That test is a one day end-to-end communications test from some of the highest points along the trail as shown below. In contrast, this survey is more of the boots-on-the-ground test of individual coverage. On 24 July 2011, the golden packet test had people on all 15 mountain tops. This was the first year with someone on Katahdin, Tim, KA1YBS! (see photo below).

Is it LIVE or is it Google?: Google Earth is a fantastic tool for planning your hike. In many places you can zoom in and even see individual trees, rocks and logs! The next two images are the Google View and an actual photo provided by W4WWQ. The ray traced is towards Mt Rogers.
