Strip back the CW1308 and think these cores are a bit stiff, wire everything back up. POTS works fine, good level, no audible noise, hum, crackles, etc.
ADSL2 (up to 8 Meg) on the other hand is not happy. Daytime sync rate was persistently 1 Mbps lower than previous that had bee rock steady at just over 6 Mbps (not bad to 3 miles of old ali). Looking at the plot of the number of symbols/carrier it is obvious that LF and MF broadcast stations are really clobbering things. It's now got dark and it's even worse, sync rate 2.5 Mbps lower and basically no symbols being above about 500 kHz, the MF band starts at 526.5 kHz...
All I've done is shorten the dropwire by 3 yards, and use this new bit of "CW1308". The wiring down to the current location of the ADSL modem is unchanged. Close inspection of the new CW1308 shows it to be copper clad steel, yes steel, not ali, it is magnetic.
Could this dubious bit of CCS be better at receiving the MF interference, have a funny resistance/impedance or perhaps joints to it doing "odd" things? I can't think how but the ADSL is definatly suffering a lot of MF interference.
Everyone home now and taking down the 'net connection would not be conducive to family harmony. Tommorow I'll switch to a pair in one of the (copper) Cat5e's and see what happens. Most odd and be interested in others thoughts.
