Re: [Signals] Should SNR swing as much as 1dB with temperature?

I've never noticed a change in download SN ratio with temperature. And we have large temperature changes here in Colorado. It can be 0 deg F in the early AM and get to 40, 50 deg F or more by 3 PM. What really changes w/ temp that can affect internet is upload signal. In my experience, if it gets to 50 dB Mv and maybe higher, internet can be lost. Downstream power also changes w/ temp, but doesn't seem to be as critical as upstream signal level. YMMV.
