To be honest, 104.9 has been nothing but a joke ever since it moved in from Johnstown in 1999. They tried a modern rock/modern AC format (Z104.9, which is where the WZMR calls came from) and it failed against WQBK/WQBJ (The Edge) and WCPT (100.9 The Point back then, now WKLI), which led WZMR to take WHRL's dumped jazz format after it flipped to modern rock. Though successful for a time, declining ratings led the station to tweak to urban AC in 2003 (104.9 Love FM), which didn't last very long and didn't help ratings much AFAIK... so it stunted with all-Christmas in December 2004 before becoming a simulcast of Froggy 107.1 in Glens Falls.
Froggy on 104.9 felt more like a placeholder to me (remember that trust Pamal tried to put the Glens Falls stations and WZMR in in order to move 105.7 into Albany? The FCC disapproved it and now Townsquare owns 105.7 as WQSH) as they were trying to sell the station in 2005. However, with the FCC rejecting the sale of 105.7 to Pamal, they kept 104.9 (and LMAed 105.7 until its signoff from Queensbury in May 2006), and flipped it to active rock as "104.9 The Edge" in 2006. Out of all the formats tried on 104.9, this had to be the most successful format on the frequency for a while, but eventually declined, leading to its demise in the early 2010 Pamal shakeup (with Magic moving to AM replacing news-talker WROW, Bridge launching on 100.9, and Cat Country on 104.9).
Cat Country still hasn't been doing so hot on 104.9, and neither has the Bridge on 100.9 (pretty much a WRVE clone). If Pamal had the right idea, they'd put a Froggy simulcast on 100.9 instead of launching Cat Country on 104.9, and consider putting a satellite-fed format of some kind on 104.9 (either a Classic Hits format like WNYQ/WBPM, Urban AC, or Classic Country would be good options)...
As for its signal, it's the weakest out of all the Albany stations (can't receive it very well in Schenectady, at least where I am) and led to poor ratings on the formats that were tried on that signal (even 96.3 has a better signal due to less adjacent-channel interference). And no, 104.9 cannot increase power because you've got WSPK-104.7 to the south, WAMQ-105.1 to the east and WTMM-104.5 to the north, so there's no way 104.9 will ever upgrade.
