Shortwave radio with a purpose
Radio Delta AM is not just a station playing records on shortwave. We are a community-driven shortwave project where music, transmitters, antennas, propagation and listener reports all come together.
Built around listeners and reception reports
Every report helps us understand how Radio Delta is received in the real world: which frequency worked, what signal quality was heard, which receiver was used and what antenna made the difference.
-
Music with a real shortwave signal. Our programmes are made for listeners who enjoy radio as an experience, not just as background audio.
-
Reception reports become data. SINPO, location, receiver and antenna details help us compare bands, seasons and antenna systems.
-
DXers are part of the development. We share what we learn, explain our technical choices and use listener feedback to improve future broadcasts.

Our shortwave strategy
Shortwave changes with the season, the time of day and the condition of the ionosphere. Radio Delta AM therefore uses a practical band strategy instead of treating one single frequency as the whole station.
Our base approach is clear: the 75 metre band is our winter and late-evening foundation, while the 49 metre band is our main European band during the summer season and evening broadcasts.
For daytime coverage we may use the 31 metre band, and for special long-distance reception or DX openings we may test the 25 metre band. Exact frequencies can change because of propagation, interference, antenna tests and international frequency use.
That is why this homepage explains our band strategy instead of listing every temporary frequency change. The current frequency, UTC times and programme details are kept on the Program Schedule. Technical background, antenna tests and reception results are shared on the Technology pages.

Seasonal bands, practical choices
Radio Delta uses each shortwave band for the job it does best. The exact frequency may change, but the idea behind our band choices stays the same.
75 metres
The lower band for winter evenings, longer darkness and late European reception. This is where Radio Delta has its traditional low-band character.
49 metres
Our main summer and evening band for European coverage. This band gives Radio Delta flexibility for strong regional and international reception.
31 and 25 metres
Used for daytime tests, special openings and longer-distance reception when propagation gives the higher bands a real chance.
Data-driven shortwave, shared with listeners
Every reception report helps us build a clearer picture of real shortwave performance. We use this information to improve our broadcasts and to create Technology updates that show what is actually happening on the bands.
Real signal reports
SINPO, UTC time, location and frequency show how the signal behaves across Europe and beyond.
Receivers and antennas
A portable radio, SDR, long wire, loop or home-built antenna all tell a different story. This makes every report technically useful.
From report to improvement
Listener data helps us compare frequencies, refine antennas, document coverage and explain our choices in future Technology posts.
The Radio Delta sound
Radio Delta is built around music, stories and the warm sound of AM radio. Our programmes are designed for listeners who enjoy the atmosphere of real broadcasting.
Five Decades of Music
Classic tracks from the 60s, 70s, 80s, 90s and beyond — selected for a broad international shortwave audience.
Stories between the songs
Record stories, radio memories, listener moments and short items that make the broadcast feel alive and personal.
Pure Dutch & listener voices
Dutch music moments, Radio Delta Heroes, reception reports and listener stories connect the programme with the people receiving it.
Radio Delta Heroes
A Radio Delta Hero is anyone who listens, reports and helps keep shortwave alive. Your report can become a pin on the map, an eQSL, a story or part of our technical reception database.
We value every kind of listener: the DXer checking SDRs across Europe, the collector using a vintage receiver, the hobbyist with a home-built antenna, and the casual listener who simply enjoys hearing real AM radio over the air.
Send your reception report, tell us what you heard, share your setup if you like, and help us build a living record of Radio Delta on shortwave.
A voice from the map
One signal. One listener. One Radio Delta story.
Heard around Europe and beyond
Every pin is a real listener location. The homepage map gives a quick view of the Radio Delta community. The full Listener Map shows the wider picture with reception reports from around the world.
