We are asking listeners to report as often as possible during this season. This will help us determine the best compromises to make in setting up broadcasts to various regions. Some of you will be able to hear all four broadcasts each week. Others may only hear one each week. That is due to the antenna patterns we will be using. Reports may be sent to ktwrdrm@twr.org or using the embedded form below.
We would love to hear about your hardware / software / antenna and if you tried to test a new smartphone / tablet App to decode DRM (Android based, we hear Apple is on the way)
If you have DRM Logging capability (DR111, DREAM Logs, etc...) We would appreciate receiving this data!
To capture DRM Data with DREAM DRM Decoding software:
- Open the “Evaluation Dialog” Window
- Click the “Log to file” box
Two logs (DreamLog.txt and DreamLogLong.csv) will be written to the root folder of the DREAM
software.
Please upload your Data log files HERE
We have created a special form for DRM broadcast reception reports:
