How portable can a #QO100 station be? Ultraportable, when running #FT8. No dish, <100 mW out (note the 3dB attenuator) and a 5000 mAh battery can power it for the whole day. 486 FT8 QSOs using this setup from JO89πŸ‡ΈπŸ‡ͺ so far. Few notes and thoughts

This is neither the most light-weight nor elegant setup, yet it takes less backpack space than my LEO gear (2xFT-818 & Arrow). The size can be further cut down if an SDR is used. I don't do #SOTA or #POTA but have not heard of anyone adopting similar approach in their activations
1) 13dBi RHCP cavity-backed patch antenna on TX (FPV drone racing antenna will do)
2) Bare, modified single LNB on RX
3) Primitive bias tee and high-pass filter to enable GPSDO input and IF out from LNB via one cable
4) DXPatrol upconverter
5) Leo Bodnar GPSDO
6) Cheap SDR dongle
