Yo, I believe is the appropriate salutation; it's been a long COVID...
First, a question for John: What was the antenna and where was it (indoors, outdoors, sitting on a pvc pole waving in the wind?

Those are called "Lassie Errors". Content free.
Does anyone here have Timb;e contacts?
Not anymore, thankfully but let me reach out to someone who might.

Which are about 10x worse than NRCan.
