DD5LP/P – May 19th 2026 – Activation in Rottenbuch of DE-1059, DE-0968, DE-0797, DE-0641 & DE-0594 5-fer POTA

Preparation:

Having seen that I had been awarded the Rover Warthog (5 parks in a day) award for my activations 3 months ago, I started looking into the Rover Awards. Given that they also work with locations that are in multiple POTA entities, getting to the next (Rhino – 10 parks in a day) should also be possible. For that attempt (using the fewest “PLOTA” stops), I need POTA sites with multiple codes. Looking at the maps for Bavaria, I found two spots near the village of Rottenbuch that have FIVE POTA entities in one spot. As I had not activated in Rottenbuch before (but driven through it many, many times to HEMA and SOTA activations), this activation was to be a test for a later attempt to get the Rhino, and possibly even higher Rover awards. As the forecast said that Tuesday morning, at least, was going to be dry, I decided on May 19th and as usual, loaded the radio gear into the car for an early start.

The Activation

POTA DE-0594 Münchner Jakobsweg DE-0641 Via Romea NHT DE-0797 KönigLudwigweg DE-0968 Romantische Straße DE-1059 Ammer von Alpenrand zum Vogelfrei Ammersee Südufer

The 40-minute drive down started earlier than planned, as I was ready and the weather was fine. I had programmed both possible locations into Google Maps, and when we approached Rottenbuch, before entering the village, the GPS navi told me to turn off the main road. I thought I must have selected the wrong option, as indeed one option was in that direction. I carried on along the route I had seen on the map. My first possible location was near the sewage works, behind the town hall. When I got to what I expected to be a drivable track, it turned out to be a pedestrian/cycle way and had been changed to this sometime, many years ago. It would, of course, have been possible to park in the village square and walk into the spot with my portable radio gear, but rather than do that, I decided to check out my second PLOTA spot, which indeed took me down the road on the outskirts of the village that the GPS had chosen previously. Off this road is a track to the sewage works from the other side. Continuing on to the second location (driving around pot holes on a road that was only wide enough for one car, but was a proper tarmacced road, I eventually found somewhere to park, next to a holy cross and direction signs for the various tracks. So that is where I parked.

I had intended to start on 20 metres as usual; however, when I turned the radio on, it was still on 40 metres from the last activation, and there was a strong signal from an IOTA station. I re-adjusted the antenna for 40m and called and worked them. Rather than switch then to 20 metres, I had a tune around and found a nice band with not too much atmospheric or man-made noise. Having spotted myself on the POTA cluster, I received 11 calls in 12 minutes. Once the calls dried up, I decided to go back to 20 metres, but got no calls on that band. That is despite hearing several VK stations easily and one HS0 (Thailand) station. Before packing up, I found and worked a Youth Sports special event station, TC19TC from Turkey.

  • Komunica Power HF-PRO2-PLUS-T loaded vertical antenna.
  • 3-magnet car roof mount and single magnet mount (single not used).
  • 8 Ah LifePO4 battery.
  • 2 x 4Ah Eremit LifePO4 batteries (not used).
  • Lightweight headphones.
  • Smartphone for spotting.

Conclusions:

This was a successful activation and a lovely RF quiet location. Setting up, operating, and shutting down from the PLOTA configuration makes it ideal as part of my “RHINO” attempt. All equipment worked well. Next time, I may check out the other location (same park and trails) for comparison.

DD5LP/P – September 19th 2025 – Activation of 2-Fer POTA – DE-1059 Ammer von Alpenrand bis zum NSG & DE-0595 SüdOstBayern Jakobsweg.

Preparation:

DE-1059 was another new POTA park added from the WWFF scheme (I believe), and I wanted to get my name on it as the “First activator” (#36 for me). As my wife had an appointment in Weilheim, I was able to find a spot where the POTA trail DE-0595 (that I had already activated as part of a 3fer earlier) crossed this park, right on the River Ammer. The wife’s appointment in Weilheim was at 8 am, so this meant I should arrive at my spot (a 10-15 minute drive south) in time for some long path DX into VK if propagation was favourable.

Again, given the limited time available, this would again be a “PLOTA” operating from the car. So the same radio gear as used for the last activations was packed into the car, ready to operate, the day before. There was one change, however, in that the horrible, faulty crimped PL259 plug on the coax to the 3-magnet antenna mount had now been replaced by a “real” soldered-on PL259. I also packed a backup single magnet mount.

The Activation

POTA DE-1059 / DE-0595

After dropping off my wife in Weilheim, the drive to the location was uneventful. The ideal (concreted) parking area was closed as road workers were using it to park their large machines. I had already seen a warning about this on Google Maps and found another, hidden-away parking area at the start of a trail where the locals take their dogs for a walk at the other side of the river and directly (as you will see from the pictures) on the trail. When I arrived, it was empty so I parked long-ways so that the vertical antenna would be clear of the trees. When I left, the spot was full with three other cars that I hadn’t heard while I was operating with my headphones on.

The activation itself was interrupted by a phone call, which lasted over half an hour, so I was a little rushed to get the needed 10 contacts to qualify the park and trail.

Conditions were not as good as I had hoped, and after fighting for contacts on 20 metres (albeit including 2 into VK), I moved to 40 metres to get the needed extra contacts as the time approached when I was to pick up the wife and drive another 1,5 hours to visit a friend in hospital.

I tried many times for a park-to-park with a VK4 station, operating from a beach in a park in VK2, but the pile-up was terrible – had I got enough attention, we could have made the contact. In POTA “Park-to-Park” doesn’t have the priority that “Summit-to-Summit” has in SOTA, where another chaser that hears you trying to get through will normally tell the other summit station to listen for you. The POTA hunter community seem to be more self-self-self. A real shame.

Conclusions:

it seems that I have found and fixed the antenna connector problem from the last activation. Given the relatively poor conditions, I think the work of those two VK operators speaks a lot for their efforts. I would have loved to make the DL-VK Park-to-Park contact, but thanks to the POTA Hunters, that was not possible.

73 ’til the next activation!
