Rundfunkempfang auf Kurzwelle: Eine Einführung

Kleiner Streifzug-1

Nach wie vor sprechen internationale Rundfunksender noch mit einer starken Stimme auf Kurzwelle. Diese Einführung beschreibt auf 33 Seiten und mit 31 instruktiven Abbildungen sowie vielen integrierten Hörbeispielen, wie diese Kommunikation zwischen Sender und Hörer funktioniert. Anders als sonst, wird hier auch die Planung aufseiten der Sender berücksichtigt – und was wir Hörer davon haben.

Schon das opulente Cover (siehe oben; Dank an Christoph Ratzer, OE2CRM!) zeigt, dass in diesem Thema weiterhin jede Menge Musik steckt!

This 33-pager in German has been written as introduction into international broadcasting on shortwave. It covers frequency planning of the transmitters as well many aspects for us listeners. 31 illustrations and many sound example may make it digestible even for people who don’t speak German.

Five Mongolians on Long wave

Since I visited Mongolia in 2001, I fell in love with this country. Hence, reception of all their radio stations on long wave caught my double interest. With some help of other listeners, I managed to receive all stations and analyzed their reception. Without any 100 g of Chinggis Khan Vodka, to which I surprisingly bumped into at Sarazul at Warnemünde in late summer 2015 …

Read this paper, to get also some information on how to receive and analyze stations which even might be too weak to hear.

DynamikFCD_E

FUNcube Dongle PRO is an USB stick, containing a great SDR at a low price of around 200 Euros. It makes a fine choice if you are seeking a serious start into the world of HF & SDRs.

I had much fun in gettingout the most of it regarding the HF bands. My enthusiastic experience resulted in this paper: 16 pages with 43 figures showing how to use this great little SDR in receiving, decoding and analyzing. Many aspects are covered, with broadcast, Amateur Radio and Utility DXing only some of them.

The key success factor in the congested HF bands is shifting the quite limited dynamic range to it’s proper place (see Illustration from the paper on top). This simple technique results in stunning reception of even Decoding delicate digital signals of 2.400 baud out of Tahiti in Germany!

This paper explains in detail on how to get the most out of this receiver.
