Excellent propagation conditions on the lower bands brought strong signals in the X-band and below in recent days. In the time around sunrise, around 5 o'clock UTC, it was really fun for a long time to hear Radio Monumental from Quito Ecuador at 1510 kc. But also WPTX from Lexington Park, Maryland at 1690 kc and WGIT Faro de Santidad, Canobas, Puerto Rico at 1660 kc were very well received for some time. Outstanding was also the reception of ZYO701 Radio Roraima from Caracaraí, Brazil at 1390 kc. All logs were made with the K9AY switched to NW.

QTH: D-35390 Giessen/Germany

All 50 m Antennas are connected through a RPA-2 Preamplifier.
I am working on a 250°/ 70° direction.

On 24.10.2018 at 1624z I managed the reception of 5AN, ABC Adelaide on the frequency 891 kHz. The weak signal could only be identified with the help of the webstream. The 50 kW transmitter from the state of South Australia is my first Pacific broadcast on medium wave.

Actually, everything was not a problem. The components were assembled, the elements assembled, the wire roll positioned in a bicycle trailer, and we went out to the neighboring meadow. There, first the earth piles with the connection components were cut into the dry soil, then the galvanized 300 m cable was towed from point A (NE) to B (SE), the 80 m long coax was laid out to the hut, and the RPA- 2 connected. The first test showed remarkably good signals over the entire medium wave, no additional amplified noise due to the preamplifier, in short: the perfect antenna for receiving from the NE direction. A two-hour recording showed me later, how good 300 m antenna cable can be.

I sat in my garden hut in front of the waterfall screen and listened intently, likening the reception to the now weak K9AY, it was around 1930z when I heard voices unknown from outside. When they did not stop, I left my seat, walked to the shack, and watched a person slam through the blackberry hedge. I would not want to go through that, I said. Police, was the answer. In the light of the flashlight I could see the lettering on the man's jacket. In fact, I said.

Displaced dog owners carrying their Fiffies on the meadow suspect a power cord, the policeman said, while his companion expertly examined the coaxial cable. It's an antenna, I confirmed, and that's guaranteed no electricity in it. Good - the law did not come to the dicuting. Now the identity card was checked, a radio check was made, and then I was allowed to roll up the quickly mounted antenna again. So that the dog owners can perform their Fiffies again the next morning. We'll check that later, they said before I let them out through the official entrance to the garden. No, we do not want to go through that again, they said, and disappeared in the darkness of the night.

Days later, I realized that the preferred direction of arrival from NE was not guaranteed at all, because one earth point was in the wrong position. So it is not even a pity that the experiment did not work out. It was exciting enough, from planning to firing.

40 safe meters remain me, NE 4-5 m pulled over the impenetrable blackberry hedge, soon. After all, it's my garden, and I do not keep dogs.

Antenna building material for a 350 m BOG. The line should run in NE / N direction, be largely invisible, and waterproof. Most of the material comes from a pasture fence shop, secret slogan: "Your partner for good MW-DX". The antenna is placed as soon as conditions permit on the neighboring meadow.

For construction: The Beverage boxes are installed in watertight HT tubes, the cables are routed through watertight cable feedthroughs. The ground wires at both ends are bolted to the ground rods. An approximately 60 m long coaxial cable is laid underground to the shack. If necessary, the ring insulators are placed in the ground at long intervals, bolted to wooden bars to keep the BOG flat and tight.

The BOG is connected to an RPA-2 Modular Receive Preamplifier by DX-Engineering.

On 26.6. in the morning around 03 UT I was able to record good MW conditions to Peru. Overall, conditions have improved again after weeks of receiving very poor signals from South America. The following stations could be identified perfectly.

All Logs of 26-6-2018 by MW-LIST

Summer is the time to check or repair the station and antennas. The Beverage Antenna matching Set from lowbandsystems has been in a waterproof plastic box for over a year. Fortunately, no rust has formed, although - after opening - the waterproofness must be questioned. A new grounding rod was inserted and connected with thick copper wire. All openings for the pipes were re-sealed. Next check is in a year.

The 60 m long wire antenna, mounted in the direction of NW, works perfectly. The noise floor is about -120 dBm. It apparently has no pronounced directivity and can also be used very well as a South American antenna. However, signals from NE / SE are correspondingly quiet.

A TP-Link TL-WN8200ND 300Mbps Wireless USB Adapter provides a perfect connection to the access point 370 meters away. The adapter, hidden behind an aluminum cover, receives the signal at about -70 dBm. Both antennas provide a gain of 5 dBI. The access point is in free visibility. An initial 18 dBm Yagi antenna is not necessary at the moment. The further development determines the nature of the garden area. If visibility is obstructed by trees or branches, reinforcement may be useful.

The farthest station I've logged on medium wave, over a distance of 12932 km: Radio Belen from Puerto Montt. The 5 kW transmitter from the province of Los Lagos could be received on 25.03.2018 between 01:41 and 02:05 h UT on the frequency 1400 kHz with the ALA 1530 S + Imperium. A short time later took CBG Gander CAN again the frequency.
