DL6AKU | Michael | JO31om | Germany/Herne | DOK:N18

At HF I am only operating portable/QRP at the moment (but also JT65 from my kitchen).

I use the Yaesu FT-817ND with a self-modified Z-817 ATU which can feed ladder line directly.

Antenna & ATU

I am a big proponent of The Easy Way, TEW (a simple doublet antenna, fed by speaker wire 75-100 Ohm Impedance).

For my TEW antenna:

I just use speaker cable 0.5mm^2 for the feeder and have split it in the middle for the doublet legs.

I have a 10m MINI pole where I hang the doublet in ~8m height as a inverted V, or when there is a good ground, like on the beach, as a 10m high vertical.

My modified Z-817 just has a choke made with teflon coax wound 5 times through 5 FT50-43 toroids. You can see the construction process when you click on the following picture of the end result:


The microphone is a MH31 with the HF Clipper Mod by Joachim Münch DF4ZS (SK✝).

I am still uncertain if the mod is useful. Some reports say the clipper is hurting me more than helping me, though I am just using it for a short time only. Time will hopefully tell. (June 2017)


I am using a 3S1P LiFePO4 battery pack with 10 Ah (a gift from DC7NTP,  thank you!) which can power my 817 for two or three typical days (about 8 hours) of activity. Click on the picture for more details.



My previous callsign was DO6AKU until Feb 2016.
