Vectored VDSL and the influence of amateur radio transmissions / 2016-02-13

2016-02-13 Vectored VDSL and the influence of amateur radio transmissions1 year ago
Another radio amateur found my earlier experiences with transmitting on 20 and 40 meters and the influence on vectored VDSL, Amateur radio transmitting influence on vectored VDSL and And now vectored VDSL doesn't mind transmitting.

He also has the problem of keying up on 20 or 40 meters and having VDSL drop completely. He shared his signal/noise graphs with me and I noticed a similarity with my first signal/noise graph: an area somewhere else in the frequency space used by VDSL which has had serious changes in signal/noise levels.

I switched the modem to a DrayTek Vigor 130 (for reasons having to do with my setup at home) and the first tests with PSK31 and JT65 on 20 meter show no problems with the VDSL modem. But the varying interference above 16 MHz hasn't returned, so maybe when this interference returns the DrayTek Vigor will disconnect too.
