Lots of avails on the WRKO Boston Red Sox Radio Network?

Probably because WRKO insists that their call letters be used as much as 
possible i.e. every 15 seconds - lest one listener somewhere, somehow 
forget what station he's listening to.  It would appear that radio 
assumes that their listeners' attention span is equal to that of a goldfish.

I've heard this inane kind repetition carried to an extreme on WBZ.  An 
example:

<live>... that's WBZ Newsradio-1030's Pat Desmarais - Saturday nights on 
WBZ Newsradio 1030.  WBZ News time is 8.24. <pre-recorded promo by 
Anthony Silva> New England is Sold on WBZ Newsradio 1030 Everyday!

and on and on...
