Published on

Portable QRO HF radio station.


  • FT-891
  • LDG Z-100Plus


  • Home made El-Key paddle
  • USB soundcard
  • Isolated audio interface
  • Coax cable
  • Ropes, carbiners, screwdriver

Power supply

  • 20Ah Lead acid battery. This is very heavy. I’m gonna change this.
  • DC Distribution box. It is now integrated into my go-box.
  • 50Watts solar panel (Planned, ordered)
  • 10Ah LiFePo4 battery pack (Planned, ordered)


  • Home made FD3 with 4:1 BALUN
  • Home made 16.2m length random wire with 9:1 UNUN
  • Home made 7.6m fishing rod vertical with 9:1 UNUN (Same for the 16.2m)

I usually use the 7.6m fishing pole with the 9:1 UNUN. However, I always pack up the 16.2m wire. The radiator can be connected easily to the UNUN.

Go pack

Most of the items are packed together in a box. I added a voltage and a thermometer to the box. With them, I can monitor the system voltage, and the ambient temperature. The measurement subsystem can be switched on or off with switch. This whole pack can fit into my backpack.
