Amateur radio operators be warned. If you are thinking of getting an Orcon Genius VDSL account, even one that delivers relatively slow speeds of say 20 Mb/s down provided through an Orcon-supplied NetComm NF4V modem, likely both 160m and 80 m bands will be wiped out completely by RFI. At higher download speeds expect the 60, 40 and 30 m to be progressively unusable as well because of RFI up to 12 MHz - directly radiated by the modem. With only the two vital cables, PSU and DSL, wound around ferrite chokes and everything else unplugged, no reduction in the radiated interference could be detected. The NF4V is the only modem Orcon provides for VDSL, so nothing else was offered (or tried). Have had to revert to ADSL: all interference vanished while still using the NF4V. Would be most interested to hear of any other experiences in this vein since NetComm have given assurance that their NF4V has passed compliance testing to both AU and NZ standards. Maybe the bar is simply set too low, or there are too few active hams still operating the low HF bands to worry about properly silencing these VDSL monsters? If the problem is encountered, prepare for a battle of the 'ageists', few younger folk understand the nuances of analogue equipment anymore, and few oldies (like me) want to be swamped out by digital hash.
