On our recent Parks on the Air joint activation at Black River State Park, WI POTA K-4348, Dave KZ9V takes me through the steps of using JS8CALL to spot your frequency location during an activation. This is extremely useful if you are in a location with poor or no cell coverage.

JS8Call is software using the JS8 Digital Mode providing weak signal keyboard to keyboard messaging to Amateur Radio Operators.
