Thanks to Steve Holden at TechNewsRadio who reports that the Sept 20 edition of SDRNews is held up somewhere in the iTunes section of the universe.
It looks like the Podtrac Player is pulling things ok and the RSS Validator has its usual scoldings but validates – but the TPN site has not pulled it for several days.
If you are an iTunes subscriber – my apologies – not sure what is going on. I hope that it clears quickly. Meantime, the direct download link is here
