But this has been the same for the 3 dry nights I've monitored, and SNRM is fine and steady (more or less) during the daytime. If it degraded to a certain value when streetlights came on, or stopped at 3am say when most people are asleep, or if it was raining. I guess the mystery (to me) is the regular and continuous degradation of the SNRM. No appliances on here at night except the same ones on during the day, and I bet most people around here are the same (i.e. Have always suspected some problems when wet, but it hasn't rained for a few days, and the SNRM is fine during the day. House was built in '86, line entry setup inside looks cheap but is in fact in good condition.
I have not found my demarc outside, it's well-hidden. Should it go back up? You'd think so if it was the lines.maybe it IS the modem. I always resync it myself later in the day. Once the SNRM starts dropping at night, it NEVER goes back up again by itself AFAIK. When the SNRM gets to 8 the FEC is 20k+ per 7s DMT refresh LOL. Yet when I resync at 9am it'll stay at ~13.5 all day. Last night I resynched the modem at 1am (SNRM = 11) and by 3am it was down to 7.5dB. I was thinking of loading some older FW so I could get more DMT info.
