Introduction

Operating on the 20m ham radio band after dark can be quite interesting. In this blog, I will share my recent experiences and experiments with operating after dark on the 20m band. I will also provide a step-by-step guide on how to set up and use reverse beacon, a tool that allows you to see the results of your transmissions on a screen. So, let's dive in and explore the world of ham radio after dark!


Setting Up for Experiments

Before I begin, let me give you a quick overview of the setup I used for my experiments. My HF transceiver of choice was the Yaesu FT-710, known for its superb receiver and quiet operation. I also had an Acom Linear Amplfier to boost the power output. For these experiments, I decided to operate on the 20m band after dark, as it tends to be open for most of the night during the summer period.


Using Reverse Beacon

Now, let's talk about reverse beacon and how it works. Reverse beacon is a tool that allows you to see the results of your transmissions on a screen. To use reverse beacon, you need to log onto it by searching for "Reverse Beacon" on your preferred search engine. Once you find the website, you can enter your call sign to access the map that displays propagation information.

Logging onto Reverse Beacon

When you log onto reverse beacon, you will see a map that shows the current propagation conditions. The map displays different regions, indicating whether it is daytime or nighttime in each area. This information is crucial for understanding which parts of the world you can potentially reach with your transmissions.

Sending Test Calls

To see the results of your transmissions on reverse beacon, you need to send out test calls. You can do this by setting your transceiver to the CW area of the 20m band and sending out a CQ call followed by your call sign. It's important to note that you should use the phrase "test test test" before your call sign to indicate that you are performing a test and not looking for replies. This will ensure that you receive accurate results on reverse beacon.

Interpreting the Results

Once you start sending out test calls, you should see the results appearing on the reverse beacon screen. The screen will display spots from different regions, indicating which areas are receiving your transmissions. It's important to note that the results may vary depending on the time of day and current propagation conditions. For example, you may receive more spots from the Far East or the United States, but fewer from Australia. This is because the band conditions and path openings can differ throughout the day.


Experiment Results

During my experiments, I observed some interesting results. While the band seemed quiet, I was able to receive good reports from the Far East, including China. This was encouraging, considering that my antenna was a simple vertical one mounted in my garden. The propagation to the Far East was particularly good, even with a relatively low power output. This demonstrates the potential of operating on the 20m band after dark.

However, I did not receive any reports from Australia during my experiments. This could be due to various factors, such as the path conditions or the timing of my transmissions. It's important to remember that propagation conditions can be unpredictable, and it often requires patience and persistence to make successful contacts.


Conclusion

Operating on the 20m ham radio band after dark can be a rewarding experience. By using tools like reverse beacon, you can gain valuable insights into the propagation conditions and the reach of your transmissions. It's important to remember that the band conditions can vary throughout the day, and it may require some experimentation to find the best times and paths for communication.

I hope this blog has provided you with a better understanding of operating after dark on the 20m band and using reverse beacon. Remember to have fun and explore the possibilities that ham radio offers, even when the sun goes down. Happy operating!
