Spread spectrum @ 49 Mhz

I am not 100% sure this is 'spread spectrum' but it seems like it could be at least a variant of it.  I see this frequently during summer time foEs.  I'm not really sure where it originates.  I suppose this is most likely a cordless telephone not too far from here.  



Also seen in this video between 49800 and 49900 are various clear voice baby monitors (not encoded/encrypted)
