power levels & temperature
 
Before weather became hotter (& hope will stay for a while to enjoy sunshine) my power levels was always "playing" around -0 to +2db depending day or night

I have notice last days temperature is over 28c power levels are gone down to -3.7db...that's 4-5 db less in some times of the day/night

I have seen other thread around their power levels gone 4-5bd higher while mine getting lower

Guessing more hotter more lower power levels?as amplifier at cabinet trying working with heat, lowers its capacity?(like older cars with out water coolers when was getting hot the power was going down as was getting more tired the engine?)

Any one with lower or higher power level during hotter weather?
Thanks

The hotter it is the higher the upstream goes and the lower the downstream. It's not jut the amp, hot cable is more resistant than cool cable

Yes that exactly what happened to me up -5db downstream and up to +2db upstream

Guessing people with very high/low borders will facing issues if hot weather will stay longer

Thanks for fast reply

It's the same when it's really cold, get sent to low upstreams

That's why the recommended range is so narrow (-7 to +7) when the actual spec range is -15 to +15

My superhub actually lost connection the other day, and the log reported that is was because the temperature was too high. Took most of the day before it would turn back on.

I want my stable 50mb back!

We'd be very interested to see a copy of the log that said your temperaure was too high. If it was a PC log, then that wouldn't be network related.
