Full DRM with xHE-AAC 18 Khz format

Postby vu2mb » Sun Jul 11, 2021 10:24 am

Hello,

Lately, I am decoding DRM broadcast on Shortwave and also MW.
I have found out that India like few other countries broadcast on few frequencies a Full DRM
that is 18khz wide and can not be decoded by PowerSdr and Thetis unless they have an 18 khz filter.
So we need now DRM 9 kHz and 18 kHz wide filters.

9 kHz DRM signals using the latest codec xHE-AAC working perfectly. Screenshot attached. ( 1st picture)

May I request the Thetis designers to look into it and provide the required filters?

Attached, Please find the screenshots of the broadcast. (2nd and 3rd pictures)

Thank you for reading this post.
