DM/BW-853 – Blankenhalde – 871m (2)


June 12, 2021  09:00 – 13:30 UTC
My second activation of Blankenhalde, this time together with DC1SAF.

Wx: Sunny, few clouds, approx. 25°C, light winds
Walking time: almost zero – drive on location
Ascent/ descent: approx. few vertical metres

Rig: KX3 / 10W,  7.2Ah SLAB, Palm Mini Paddle, Belcom LS202E / 3W for VHF
Ant: EFHW dipole w/ QRP-L-Tuner as inverted L on a 10m squid pole, MFJ1714 for VHF

Condx seemed to be good. DC1SAF worked one station from NA on 20 metres.
k = 1, SFI = 77

12 QSOs on 2m FM, 11 x S2S
14 QSOs on 40m CW
12 QSOs on 60m CW, 7 x S2S
2   QSOs on 60m SSB, 1 x S2S

– First CW SOTA activation of DC1SAF
– Because of the HB9SOTA-weekend an incredible number of Swiss activators was QRV. Many of them could be worked on 2m FM with my old Belcom LS202E and about 3 watts output power.
– Great aerial views of the summit thanks to Fabian’s quadrocopter

– none

Activation report:

Blankenhalde is one of the few summits on Swabian Jura I haven’t activated yet this year. It’s a drive-on location where you can earn ten activator points easily. Additionally, it offers a good VHF take off towards Switzerland, where the HB9SOTA-Group held their annual SOTA-day (which was actually a whole weekend).
Fabian, DC1SAF, joined me on this trip for his first activation on CW.

I arrived a bit early and set up the HF antenna while the 2 metres HT was on standby. It wasn’t long before I heard Sabrina, HB3XTZ/p, calling CQ SOTA from HB/SZ-025 on VHF. Then things really took off and soon I had six S2S-QSOs in my log – all with HB9 activators!
When Fabian arrived, we had a brief chat, then I activated on 60m CW. Besides a couple of well known chasers, four more HB9 S2S-QSOs (and one non-Swiss S2S) went into the log.
When the pile up abated, a farmer arrived to make hay with his huge tractors. So we had to temporarily remove the antenna (not for the last time as we would learn later).

Then DC1SAF set up his station and called CQ on 20m CW (while I had three more S2S-QSOs on VHF). The activation picked up pace, once a spot had been submitted on SOTAwatch. Three or four stations were calling at the same time, giving Fabian a hard time 😉 But he did very well and completed the QSOs one after the other. Highlight was the contact with KA1R, the only DX of the day!
Afterwards we relaxed and performed some quadcopter flights around the location.

Then it was time for a brief intermezzo on 60m SSB, where I had a sked with IN3ADF/p on I/AA-133 and DL6FBK at home. These QSOs came to a rapid end as another farmer appeared. He came quite close and I was concerned about our equipment. So I offered to remove antenna and station completely. Luckily he waived it but Fabian had already dismantled his station by then.
Therefore he used my antenna for his activation on 30m CW. Again everything went very well and finally DC1SAF had 12 QSOs in the log.

Finally, I ran on 40m CW. It was uneventful and soon we were taking down station and antenna. It was getting late and soon we were heading home.


  • A great SOTA day on a fairly easy summit
  • Successful activation on 20m and 30m CW by DC1SAF
  • Lots of activity on 2m FM
  • 19 S2S-QSOs resulting in 109 S2S points 🙂
  • Farthest QSO on VHF with DH6MAV/p on DL/AM-058

Again it was lots of fun. Thanks for the QSOs!

    Hi Roman, are you really carrying s 2.5 kg 7ah SLAB? 🙂

    I remember your last report of heavy rain at the summit. Thanks for sharing.

      Yes, Andrew, last time was less pleasant with lots of rain and subsequently a very brief activation. This time, the weather was perfect 🙂
      Since BW-853 is a drive-on summit, the battery type doesn’t really matter. It’s maybe 100 metres from the car, so I went for the heavy SLAB. No other reason, the 2.5 Ah Li-Ion battery would have done as well.
      I even brought a very comfortable (but heavy!) chair to the summit which I usually don’t do 😉

      Thanks for reading!

      73, Roman
