Radio DX – Norfolk Island

Yesterday’s Radio DX from Norfolk Island test broadcast on January 14, 2023, was a challenge for man and machine. Nick got up especially at 0415 local time on Norfolk to broadcast from 1630-1830 UT with only 200 watt in the tropical band on 5.045 kHz. The signal was visible from the start of transmission here in Salzburg, first audio signal just before sunrise, the “sunrise enhancement” of the ionosphere exactly at sunrise in Norfolk just after 1800 UT worked perfectly. Although the signal from the Pacific island 16,998 km away could be heard at most with S3, it may have been close to the optimum for the transmission path. The test transmission ended at 1827 UT, and three minutes later the morning program from Vanuatu, exactly 1,000 km closer, began on the adjacent channel 5040 kHz, transmitted via the 2 kW transmitter in Port Vila. This signal from the Pacific was heard with S7 in Salzburg, the best reception this winter.

I listened to both signals on WinRadio G33 Excalibur PRO SDR on my 25 mt. K9AY antenna with technology from RemoteQTH – https://hamparts.shop

A big thank you to Nick Hacko VK9DX for doing this test broadcast for Europe, to hear a shortwave broadcast station from Norfolk Island in Central Europe is a rare experience.

Radio DX – Norfolk Island

Nick, VK9DX, is currently on Norfolk Island, an island in the Pacific Ocean that belongs to Australia. In addition to his amateur radio activities, Nick holds a broadcast license to operate a radio station on 5,045 kHz in the tropical band since 2022.

So far there have been three test transmissions on local evening on Norfolk, another is today, Friday around 0730/0830 UT. Very difficult to receive for Europe as already too far in daylight. I made Nick the suggestion of a test transmission for European DXers, the reception window between 17-20 UT would be very favorable now at the turn of the year, the broadcast stations of the Solomon Islands and Vanuatu rarely but still to be heard on 5 MHz.

And indeed, in the coming days, probably Sunday or Monday – while Nick is still on the island – there will be a short test broadcast between 16.30 – 18.30 UT from Norfolk!

An extremely rare opportunity to hear RadioDX from the Pacific in Europe.

MW-Logs.

Here are my MW logs for the first days of January 2023. Currently there is very little to hear from Asia, in the afternoon sometimes only 1-2 stations from China. Only from the Arab region and Africa can some signals be heard. The transatlantic reception is similar; if a handful of stations land in the log, one can be very satisfied.

New: hamparts.shop

Jan Šustr “RemoteQTH / qro.cz” has opened his new website hamparts.shop today.

There you can not only buy the products, but also find very good and understandable explanations on how his products work, such as antenna boxes, distributors and controllers. I have been using his products for years, they are perfect in terms of technology and price. Definitely have a look!

Stream Deck!

I control the antennas of my receiving station via the Internet. This is possible with a web browser, but also much more elegantly with the small Stream Deck from Elgato. Mike Müller from Remoteswitch.de has programmed the appropriate extension for this, in the current version also with a status display. So I can now operate my RemoteQTH antenna switch simply by pressing a button and within a second I also get the feedback – and the corresponding button lights up. A wonderful solution, with a lot of invisible work in the background.

Thank you DM5XX Michael Müller, very good work!

The picture shows the monitoring bus with my 200 Meter USA/Africa Beverage.

Today I was at my station with two officials from the Salzburg telecommunications office to find my interference in the medium wave and 160 meter amateur radio bands. They examined in detail what I was receiving and how and then the measuring bus, equipped with the very best Rohde&Schwarz equipment, drove around the area for a long time. 

After some time, I got the call – they actually found the interference far away in a westerly direction, a defective (but high-quality) surveillance camera that had been in use for 10 years and – presumably the power supply – was now causing this interference under load. I was at my station when the fault suddenly disappeared. Score. The owner will hopefully replace everything as soon as possible.

It was great how competently and quickly I was helped by the Austrian Radio Monitoring. Many thanks for that!
