Little-noted callsign change

[Garrett Wollman]

CBS has changed WBMX to WBMX-FM, with the WBMX (unsuffixed) calls
being warehoused on an X-bander in Charlotte.

>From this, I assume that the Great Switcheroo will be arranged as
follows:

First, change WBMX-FM to WBZ-FM.
Second, swap WBMX and WBCN.

AIUI, the FCC's callsign reservation system doesn't allow for swaps
involving three stations, only two, so this dodge is necessary to
protect someone else from grabbing either WBMX or WBCN in the time it
takes to enter the second call change.  (The presumed goal being to
warehouse the WBCN calls out-of-market to keep someone else from
bringing them back to Boston in competition with WZLX, just as the
WROR calls were sent out to Michigan when 98.5 became WBMX
seventeen-odd years ago.)
