While most other Canadian stations/networks have had at least a few years of digital "experience", TVO is unfortunately late to the digital OTA game. I'm sure there will be issues for some time as their technical staff catch up on the learning curve.
The other issue that I suspect for the Paris transmitter is microwave fade. While I'm not certain that TVO Paris is fed by microwave, I suspect that CIII Paris is. Thus my question of whether the issue impacted all sets at the same time.
If TVO London is fed by microwave, you'll find similar fade issues during periods of temperature change, fog, heavy rain, etc.
I might bike by the Paris site tomorrow to see if there's fibre heading into the site....just for my own curiosity. Maybe RFMAN can comment?
