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.

Stampfl products on eBay

This morning, I noticed that the Swiss radio and Morse key manufacturer, Stampfl, is selling some of their products on eBay.

In particular, they’ve listed the Junior 1 shortwave radio receiver kit (above) and the STM-11 Classic Morse Code straight key (below).

Stampfl was founded by Heinz Stampfl (HB9KOC)–I’ve been following his work the past few years, especially fascinated with his SDR designs which are (sadly) only experimental and have never been put into production.

I’m particularly fascinated with the MICRO SWRX:

And the EXPERIMENTAL SWRX:

I’ve written Heinz more than once encouraging him to put these on the market. Of course, it’s an easy request coming from a consumer who doesn’t have to front the production costs and inherent overhead!

Heinz, if you’re reading this, why not do a Kickstarter campaign for one of your fine SDR designs?!

The Junior 1 receiver kit

The Stampfl Junior 1 shortwave receiver kit looks like a lot of fun not only to operate, but also to build and I’m sorely tempted to purchase one!

Here’s a video of the Junior 1 in action:

The Junior 1 is listed as an auction on eBay with a starting bid of $50 with $25 Economy Shipping to the US. The BuyItNow price is $70.

I think $95 US shipped is a fair price for what looks like a fascinating little receiver kit designed by an (obviously) talented engineer.
