DD5LP/P – February 12th 2024 DL/AL-179 Weichberg.

Preparation:

This was a re-try of the attempted activation from the previous Wednesday when high winds made me call off the activation from the car park before I climbed to the summit. This day was supposed to be a fine, warm, sunny day but as usual, two days before the activation, the forecasts changed to overcast, cold and possible winds.

Despite that, I was determined to be ready for an activation and as long as there were no high winds or torrential rain, I would activate. All the gear was packed in the back of the car on Sunday evening ready for an early start at 7:30 am the next day.

“All” this time was to include the surveyor’s tripod and the large feed-point board for the 20/10m wire beam – this would be the first real test on a summit of the ability to switch the antenna direction from my smartphone, something that had been giving me problems for the last six months. Of course, the usual backpack with radio, battery, masts, backup antennas, food and drink, would also be included along with the RigExpert Antenna Analyser.  

The Activation

DL/AL-179 Weichberg

On arriving at the car park for the summit, after an easy (and wind-free) trip down, the winds started to howl between the trees and some threatening-looking clouds were approaching. Despite this, I was determined not to call the activation off again as Ernie in VK3 was going to be available and Mike 2E0YYY/P was heading up to Mow Cop (HEMA G/HSP-020) so that we might make this a three-way contact today (at least on 20m, if not on 10).

After a hard trek up the forest path to the summit, with a loaded rucksack, the tripod over one shoulder and carrying a bag of documents, the antenna plate and antenna analyser in a shopping bag in the other hand, the top was reached and I put most of the gear down at the wooden table.

I unpacked the antenna, mast and Tripod and went straight to the complex installation including the relay board with Bluetooth switching and the trapped antenna elements. If this did not work, I could go back to the simpler setup as I had brought everything with me. Using my Rig Expert antenna analyser I could see that the antenna (initially set in the Long Path Direction (West)) was looking fine, so then I sent a message via the Signal app to the other two, who were both almost ready.

First in the log was Ernie VK3DET followed by Mike 2E0YYY/P a minute later. Both 5-8 to 9 signals on 20 metres. For once, it seemed the system was working well, the first time. My biggest problem was using the messaging app with frozen fingers. There was a light wind which grew over time but was always icy cold. The measured temperature would have been around 3°C but with windchill nearer to -3°C!

We actually managed an easy “net” between the three of us on 20m until Mike said 10m was open and he wanted to try there, so we moved up two bands and I switched the antenna to Short Path for Australia (East from my location). After trying several frequencies, we eventually found a free one and although Ernie was getting to me at around S2, he could not hear me. When Mike tried, I had to switch the beam around to West before I could hear him (again at about S2) again, he could not hear me. So the added problem I had was this need to switch directions to hear the two guys but as they could not hear me at all on 10m, nothing was really lost. they managed to make contact and I told them I’d head off spot myself and try to get some contacts in the log. To me 10 metres sounded rather quiet  compared to other days when I have use the simplified version of this antenna but this could also be propagation. in any case I was glad of a ground-wave call from Mario DJ2MX in Munich, so that I had at least one contact on 10m from the summit.

As I was still short of the needed 4th contact, I switched back to 20m, found a frequency, spotted myself and another 15 contacts came in, in quick succession. I was certainly getting out on 20m!

All of this time, I was fighting to have gloves on to try to stop losing all feeling in my fingers and taking them off when I needed to do something on the phone. Time was also passing, so when there seemed to be no more chasers, I called it a day, packed up, returned down the steep forest path and when I got to the car, it started to rain. That was lucky timing!

Conclusions:

  • The antenna worked well with between 1 & 2 S-points difference on weak signals depending upon the direction was switched to.

  • It would be nice to have a method to have a one-button direction setting action rather than the 4 actions needed at the moment. Perhaps I will need to try to get another model of relay board to which I could script commands.

  • The 10m section of the antenna did not perform very well. Whether that was because of propagation or whether the capacitor does need to be a different value can only be tested by switching between models of the antenna (i.e. with and without the traps).

73 ’til the next summit.
