Field Day
ARRL Field Day on the last full weekend of June and Winter Field Day on the last full weekend of Januaryare a couple of events hams do outdoors....well.... at least the June Field Day ;)

APRS Mapping
I enjoy walking on trails and using ham radio both at the same time. I have a Yaesu FT1DR HT(Handheld Transceiver) with APRS and GPS built in. The GPS in the HT is more accurate the Garmin eTrex 10 GPS receiver I have, but I find recording waypoints easier with the eTrex 10. Pete N1ZRL in picture below with a APRS client program called XASTIR running on a laptop logging me as WE1U-6 by APRS.
