Radio Delta Experiment: Shortwave Comparison

At Radio Delta, our team has been conducting a series of experiments to understand and compare the performance of shortwave radio transmissions. In this blog, we will share with you our findings and the insightful discoveries we’ve made along the way.

We have put together a series of videos that showcase the comparison between the 25-meter shortwave and the 49-meter shortwave. Through these demonstrations, we aim to illustrate the differences in transmission quality and reach between the two bands.

Transmission Details:

– **Radio Delta**: Frequency – 12.030 kHz, Power – 1000 watts (PEP)

– **Radio Mike**: Frequency – 5980 kHz, Power – 1600 watts (PEP)

– **Radio Continental**: Frequency – 5810 kHz, Power – 400 watts (PEP)

One of the key insights we’ve gained during our experiments is the impact of power on transmission strength. We observed that a doubling of power results in only a 3dB increase in strength. For example, if Radio Continental were to use 800 watts, it would be 3dB stronger.

In one of our videos, we demonstrate the significant difference in reception quality within a distance of 750km from Elburg, France. This highlights the impact of frequency and power on the reach and reception of our transmissions.

Interestingly, we found that during the daytime, the 25-meter band often provides clearer reception even at a distance of 500 kilometers. This unexpected observation has sparked further exploration into the specific conditions under which each shortwave band excels.

The entire journey of conducting these experiments has been a learning experience for us at Radio Delta. Our enthusiasm for testing and our commitment to self-built solutions have driven us to understand the nuances of shortwave transmissions, and the outcomes have exceeded our expectations.

As we continue our journey, we are excited about more experiments and experiences that lie ahead for our team at Radio Delta. Our dedication to self-improvement and learning is what motivates us to push the boundaries of our understanding of shortwave transmissions.

We are delighted to have shared this experiment with you, and we look forward to your continued support as we embark on further adventures in the world of shortwave radio.

Stay tuned for more updates, more experiments, and more exciting discoveries from Radio Delta!

  1. Thanks for this demonstration. Yes. Aart, I have tested the reception as a listener on several Web SDRs in Europe and it is quite a phenomenon how brilliant and strong the reception is despite the small output of 1000 watts. And that makes reception on the 12030 kHz exciting again.
