Title: Radio Marti DRM
Post by: JimIO on March 01, 2020, 1613 UTC

 Radio Marti is now broadcasting in AM and DRM. Which one do you think Cubans are listening to and why?

All Cubans who have DRM equipment are listening to that broadcast instead of AM.  That would be... Arnie.  :)

The rest are listening to the AM version which gets jammed by Cuba.

I suspect it's vastly more effective to jam dmr than standard am. Dmr is based on S4285 wich is coded to handle one interfering and likely stationary tone, after that it falls apart quickly.

DRM pretty much self jams half the time anyway. It's a (poor) solution in search of a problem.

So, you can hear in DRM, "I am Maati! And this is my wadio!"? I miss Voice Of Laryngitis rippin' on that.
