My first DRM reception

Dear members,

I'm a beginner, this is my first message.

After a hard work I modified my ATS-818 with a Sat-Schneider mixer.

My antenna is a Degen DE31

Yesterday evening at 20:20 (UTC) it was my first DRM reception at 9950 !

I used Dream in my laptop through microphone connection.

I try to attach a picture.

Sorry if I'm not using the "conventional" type of attachments.

I will be happy to get any advice how to improve.


Best regards,

Hi, and welcome!

You could:
  • goto "View" "Evaluation Dialog" in dream
  • check the box "Log file" after entering the frequency of reception in the bottom center of the window
This will write a logfile (DreamLog.txt) of the transmission you receive in the folder where dream.exe is located: every minute the SNR and Audio quality is recorded.

Then you go to Carsten's homepage and download "DRMcalc".

In this program you can import the logfile and get the conventional type of graph which you can save by pressing the "capture" button.

Good luck!

Hello,

nearly 100 % decoded audio. Audio quality partly bad. It is not a good idea to compress the audio in a digital mode. For analogue transmissions it s OK but in DRM it decreases the quality!
