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 JO89🇸🇪 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

There are so many printers out there and OMs waiting for a solution and have no idea about this one

If you need only the helper, also fine.
Its for ~3.5mm wire (10mm²) - 30mm distance between windings - maximum 6 turns - diameter ~40mm
If you need a different, let me know.
Thanks for interest
