"bubbly" sounding TV video

[KW4RZ]

Some of the TV 2 stations in Central America, Cuba and the Dominican Republic have a characteristic "warble, wattery, and squirrely" sounds to them when tuned in on a receiver in SSB. Along with some being off frequency it makes for easy identification to get an idea where Es is coming from. All US, Mexican and other Canadian TV2 video that I've heard before has been just the normal stable carrier with "buzz" sidebands. Today this TV2 video was heard along with matching French audio on 59.750. I suspect this is CBFT Montreal which seemed to be the center of the Es target area. I've not noted this "bubbly" sound in the video before when French audio has been in but it is definitely unique. Never heard anything like it before from anywhere.
The tone changes from tuning back and forth off the carrier's center at 55.250 down to 55.240 and up to 55.260.

Interesting to read your report or watery/bubbly ch A2 vision carrier.
I received the attached clipon 28th June last year in Portugal .Was centered around 55.247 but warbling/bubbling,recorded in SSB mode & the second half of the clip is in AM.
The antenna heading was not from N.America,more Central America direction.
Any ideas?

Thanks
