via the RSGB: Survey to find the extent of VDSL Broadband Interference

The RSGB’s EMC Committee has for three years been investigating the problems of interference (RFI) from VDSL broadband on the HF amateur bands and lobbying for action to reduce the problem. We have a lot of historic data, but both Ofcom and Openreach contend that 150 reports from 50,000 amateurs is not indicative of a major problem when there are 9.5 million VDSL installations deployed. The RSGB EMCC has set up a survey to collect current signal levels at the frequencies of VDSL band transitions (these indicate the presence and strength of interference). It is very simple to do you just tune your receiver (set to AM or SSB 3kHz bandwidth) to each frequency requested note the S meter reading on the survey form. Full instructions are included in the survey.

Please fill in this survey with your current readings even if you have reported them before. As more and more people subscribe to VDSL so the level of interference continues to increase and we need the current picture.
