Radio Delta

“Keep the Shortwave alive”

About us

Radio Delta International is a dutch free radio station founded in 1971. Nowadays we are broadcasting with a license on 6020kHz and 6005kHz 49 meters shortwave with AM modulation. We are using a facility in Elburg the Netherlands. 

Radio Delta International was unlicensed by any government for most of its early life, it was a pirate radio station with a great history that never became legal. Ever since more than 49 years have passed with ups and downs. No doubt more ups than downs. What kept and keeps us going can be best described as “The love for Free Radio”.

Every Saturday evening and Sunday we bring you great ‘live’ shows on 49meters shortwave right across Europe and around the world. No tight formats or playlists, just the best music with requests and greetings from our listeners. 

We welcome your reception reports, reactions in our guestbook and whatsapp messages and by return you’ll receive our new eQSL-card with personal notes.


More and more countries are switching off their powerful shortwave broadcasters, because the internet and DAB+ frequencies offer good alternatives. This creates room for free radio forms as that from Radio Delta International.

During broadcast

Rhode & Schwarz SK080 with classic anode/screen modulation, built in 1959. 100% tube-based, 800 Watts RF, sucks 3.4 kVA (one phase!). Radio Delta engineers refurbished this beautiful vintage AM broadcast transmitter. We used this transmitter in the 80’s on shortwave 7325kHz. 

The R&S SK080 has a nice internal modulator with 2 x QB3/300 tubes with a brilliant AM modulation. This R&S SK080 transmitter could modulate around 800Watt nom. Many dutch pirates use the smaller R&S SK010 with external modulator, this transmitter can modulate around 130Watt nom.

The R&S SK family was in used by the German Army during 60’s and beginning 70’s. During the 80’s and 90’s this army surplus was sold to handlers. It was in the past rather simple to buy such a gear in Germany and Holland. Later became the R&S SK1 (1 kW max carrier power AM, + USB and LSB ) popular. But there mintage was much much less.

Radio Delta Song

On May 15, 2021, Silvia Swart recorded a song for us. This is recorded in Dutch but the melody is known from Amy Macdonald with the song Mr. Rock ‘n’ Roll.

This gives even more feeling to our free radio sound on the 49m shortwave.
