You realize of course that 2, 4 & 7 Buffalo all moved to new frequencies while CHEX and CKWS stayed on the same frequency.I received 2, 4 & 7 Buffalo analog at about the same picture quality pre-transition and I get all 3 of them great now in the digital world.
I read somewhere the FCC commenting that after the American analog shutdown they discovered that digital VHF-HI requires 10dB more power than they expected (something they considered reasonable), and digital VHF-LO requires more than 20dB more power than expected (which they considered unreasonable). That means that if they expected CKWS only needed 9kW on channel 11, in reality it needs 90kW of power.Several in the past have commented that when a VHF station transitions they lose coverage area (CHCH)
That can easily be resolved by having the transmission directional to the north and west, with a null to the south-east (though it looks like they already have a strong null to the south-south-east, probably to protect WONO-CA in Syracuse).[ Or maybe they kept lower power on purpose? Don't want to spill too much over the border ... just a little. ]
