Photos from the Radiofreunde NRW DXpedition

All Photos by Radiofreunde NRW member Tom Kamp

After recently checking out a number of photos on the Radiofreunde NRW Facebook page, I asked if a member of this group could give me a little more detail about their DXpeditions. Many thanks to Joachim Geisau who writes:

Radiofreunde NRW is an independent association of SWL, radio amateurs and technology enthusiasts. We meet 2-3 times a year for a few days in a rural area far away from urban noise to listen to radio broadcasts from the most distant countries.

Normally we set up several large antennas, mostly 8-10 different ones, both active and passive.

The antenna setup consisted of:
– two magnetic loops with 1m diameter
– two wire loops with 20 m size
– one beverage antenna 80 mtrs length
– another beverage antenna 240 mtrs length
– a PA0RDT mini whip antenna
– a DL4ZAO UniWhip antenna

Their signals are distributed via a self-made distribution unit. A total of about 6-800 m of coax cable is used. This makes broadcasts audible from distances more than 10,000 km.

Wow!  Thank you, Joachim for the information and many thanks to Tom Kamp for the photos!

That antenna farm is most impressive and I love seeing all of the Stampfl radio equipment at the DXpedition.

Post readers: If you’re interested in Radiofreunde NRW’s events, you can contact them via their email address: [email protected] They’re a multi-lingual group and can accommodate German, English, French, and Dutch!

Hungary conducts low-power DRM tests

BUDAPEST, Hungary — Digital Radio Mondiale transmissions began from Budapest, Hungary, last June. Although two Hungarian broadcasters previously tested DRM on medium wave, the transmissions are the country’s first DRM trials on shortwave.

The Department of Broadcast Info-Communications and Electronic Theory at the Budapest University of Technology is conducting these latest trials. Csaba Szombathy, head of the broadcasting laboratory, is also head of the project, which will last for at least 12 months.

While the 11-meter 26,060 kHz frequency is well known for use in local broadcasting, it’s rarely implemented for international broadcasting. […] Researchers have also performed tests in this frequency to measure coverage and determine optimal mode and bandwidth on various occasions in Mexico and Brazil. The new Hungarian trials will add to this research.

Szombathy initially operated the transmitter with just 10 W of power into a 5/8-inch vertical monopole. Radio Maria, a Catholic station, is providing a 25-hour program loop, while a Dream DRM software-based encoder broadcasts the signal using AAC encoding. In spite of the low power, the program was reportedly received in the Netherlands.

In early September, Szombathy moved the antenna and transmitter to a slightly different location to improve coverage. He increased the power to 100 W.[…]

Radio Deal: Retekess V115 $14.00 shipped on Amazon

After looking at the Eton Elite Mini sale Christian shared, I discovered that the Retekess V115 is currently $14.00 shipped on Amazon “for a limited time.”

Click here to read our previous reviews of this radio. The V-115 makes for a great portable broadcast receiver/recorder and has very pleasant audio–certainly a benchmark performer in the sub $25 category. It’s a great little backup radio to keep in the car glove compartment or go-bag. This is the lowest prices for the V-115 I’ve ever seen. This receiver typically floats around the $23-25 range.

Radio Deal: Eton Elite Mini $19.99 shipped

Many thanks to SWLing Post contributor, Christian, who writes:

Thomas: the new Eton Elite Mini is on sale for $19.99 plus free shipping from Amazon.com. This is the latest in Eton’s series of “mini” radios. If you’re looking for a nice stocking stuffer radio, this is a great one! If you already own a previous mini I wouldn’t bother buying because I feel like this might just be an updated body design. Internals are probably the same. Still while the Elite Mini is on sale, it’s actually cheaper than the discounted previous version which is currently $21.

Radio Deal: AirSpy 30% off Black Friday Sale

The AirSpy HF+ SDR

Just discovered through the AirSpy Twitter account that they’re offering 30% off all of their products via their authorized retail outlets.

This morning, I posted an article featuring their $169 HF+ Discovery. Another AirSpy SDR I highly recommend is the $199 HF+ SDR. This deal would give you 30% off those prices.

According to AirSpy, the coupon code AWARDWINNING2019 will be activated “within a few hours.” I believe this might mean at midnight UTC because they had mentioned a November 26th activation date. Although the sale extends until December 2, 2019, AirSpy states that supplies are limited.

If you’ve been considering an AirSpy product, now would be a good time to grab one!
