Step 1: Send a heartbeat and receive replies to ensure folks are hearing you. 40/20m are the most popular bands (in my experience).
Step 2: Send the following:
@APRSIS<space>CMD<space>:POTAGW<space><space><space>:CALLSIGN<space>PARK#<space>FREQ<space>MODE<space>COMMENT
Example: @APRSIS CMD :POTAGW :KB4TAD K-1300 7.265 SSB LOOKING FOR HUNTERS
(Important Syntax Notes: There must be 3 spaces between POTAGW and :CALLSIGN. Enter frequency without a decimal. Use park identifier with dash, example K-1300 for Grayson Highlands. Must use a mode that is recognized by the POTA site.)
