On air since 1975
Radio Delta AM is an independent shortwave station from Elburg, Netherlands. We combine music, listener reports, Radio Delta Heroes, hands-on engineering and real propagation tests. Every reception report helps us understand where the signal travels — and keeps shortwave radio human.
Community driven, engineering focused
We love “real radio”: antennas, RF, audio processing, propagation, receivers and the magic of signals travelling across borders without the internet.
-
Heroes first. Every report becomes part of the Radio Delta story — as a pin, shout-out, eQSL or Listener Story.
-
Real propagation. We compare 75m, 49m and 25m coverage using real reception reports from listeners.
-
Learn & share. We document transmitters, antennas, audio processing and experiments so others can learn too.

Tip: send a reception report — your pin appears on the Listener Map.
Three bands. One shortwave story.
Our frequency strategy follows propagation. The exact frequency may change, but each band has a clear role.
75 metres
3985 kHz is our main evening frequency for European coverage. This is the core Radio Delta AM service for regular weekend broadcasts, listener greetings and music.
49 metres
6040 / 6190 kHz may be used as a bridge frequency, especially when the higher bands are fading and 75 metres is not yet ideal.
25 metres
Around 12 MHz we run experimental DX tests for longer-distance reception, especially beyond Europe and beyond 750 km.
A voice from the map
One signal. One story. One Radio Delta Hero.
Heard around the world
Every pin is a listener — and every listener is a Radio Delta Hero. The Listener Map now also helps us compare 75m, 49m and 25m propagation.
