We do want everyone to include basic info in their packet though. Please include PWR,Antenna Gain, and RATE. Such as "5W,3dbi,5min" so that the statistics will show us what works...

だそうです。デジ成功した局の設備，知りたいよね。APRS では PHG - Station Power and Effective Antenna Height/Gain/ Directivity を設定する局が少ないので，メッセージに含めるのだと思います。
