Last week I mentioned my commentary “Why we need Shortwave 2.0” in the trade publication Radio World. This weekend’s show will include most of that article in MFSK64 text.

Radio World also received a letter from Ruxandra Obreja, chairman of the Digital Radio Mondiale Consortium, claiming “We Already Have ‘Shortwave 2.0’”

The DRM Consortium seems to want it assumed that DRM is the future of shortwave. I have decoded hundreds of hours of DRM since about 2000, when I organized the first DRM reception demonstration in North America. DRM is great when it works, but I have witnessed too many failures of DRM decodes in typical shortwave conditions.

I would like to see a nightly transmission from Europe to North America, a half-hour each for DRM and for text-via-analog we use on Shortwave Radiogram. Let’s find out which technology is more successful in trans-oceanic shortwave communication.

A video of last weekend’s Shortwave Radiogram (program 338) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is provided by Roger in Germany.
