"No significant loss of listeners to satellite" from Stern's defection

Inside Radio had a bit of spin based on the recent Winter Arbitrons:

Katz researcher Maggie Hauck says “Howard Stern listeners have stuck with terrestrial radio despite all the hype.” From the first batch of Winter Arbitrons it appears “the Stern audience poured out all over the terrestrial radio dial” — scattered among other stations — but “the Persons Using Radio levels barely budged.” So Americans (at least n the biggest markets) didn’t run to Sirius to catch their idol. [...] What Katz is saying is that the total audience — the PUR — didn’t shrink in this Winter book (so far).

I'm not the only one who found this funny, as Radio Marketing Nexus found some curious discrepencies with this. See, apparently Katz forgot that Satellite Radio listenership is now recorded and as a result SIRIUS listeners are counted towards Persons Using Radio. So there definitely was no "signficant loss" because Stern's listeners just moved from one row to another. In fact, Arbitron told the Nexus that almost 4% of the NY MSA diarykeepers reported listening to Satellite Radio in the Winter book.

Hmmmm... so that didn't work. What about those not listening to satellite? The audience that "poured out all over the terrestrial radio dial" as it's so colorfully stated?

This from Nexus' inside source on the NY numbers:

Let’s look at 25-44 men (Howard’s core demo) in morning drive. [The AQH] figure is off 3% book-to-book and 9% this Winter compared to last Winter!
