There's been a lot of speculation that the move putting classical on 99.5 and country on 102.5 is not "optimal" but it "could work"
The problem is that 102.5 is just outside Boston/Cambridge on the Needham tower cluster (where Rt.9 crosses Rt.128/I-95). So it gets excellent coverage of the more affluent metrowest suburbs and (for the most part) good coverage in the city where a lot of businesses have WCRB's classical on during the daytime.
99.5's stick is significantly further north; up between Lowell & Andover (where I-93 crosses I-495). Even though it's a 27kW Class B...that distance from Boston means it doesn't penetrate the city very well, nor does it reach metrowest terribly well, and it doesn't get anything in the South Shore at all. However, it does get into the more urban areas of Lowell and Lawrence, as well as north shore towns like Saugus and Lynn, quite well.
I'm stereotyping somewhat as to which towns have classical fans (more hoity-toity and affluent) and which towns have country fans (more blue collar) but hell, isn't that what Arbitrons are all about?

Anyways, the reach of 99.5 is probably "good enough" that a lot of WCRB's classical fans will still be able to hear the station...especially in their cars. But there's no question that country fans are getting the better end of this deal.
What should be interesting is to see what happens on the South Shore. Arguably 102.5 has had signal problems on the South Shore, esp. the shoreline proper, because of tiny Class A 102.3 in Truro skipping across Cape Cod Bay. But regardless, 99.5 has no presence AT ALL on most of the South Shore...so any WCRB classical fans down there are SOL. Are there a bunch of hungry country fans waiting for 99.5's format to suddenly reach them much better on 102.5? Well, that's a $100+ million dollar question, now isn't it?
