What is a "Field Day"? It's like Amateur Radio Operators who take their 'gear', (radios, antennas and power supplies), out to a remote location and "setup" for communications with others.
How would a TI'er do a field day? Well, you would take your 12V power inverter, or your UPS, with you along with your TI, TIPI/Rpi and cellphone. Once you setup in the remote location, you would use your TI/TIPI/Cellphone to connect with Heatwave BBS.
Take photos or a video to document your achievement. Does this interest anyone?
