Dear All,
As a precaution I wound
the phone and power leads to my old ADSL netgear 834WG router on to separate
red ferrite rings and have also used the big clamp on ferrites too and it sits
quite happily with RF, even when I have the TL922 on at legal limit. It my /A
QTH in NI I have a Sky broadband router and that’s in the same room as
the atu/balun and end of my long wire, so far from ideal in terms of RF good
practice, this too is fine with 100W out from my TS570 except on 40m and topband
where the ATU seems to struggle and so mismatch is causing some interference
which drops the ADSL.
For me I use the ferrite
winding pattern as is oft described in the RSGB tomes.
Curiously, ferrites did
not cure my very noisy APC UPS (1000W unit) and this renders 1 to 30MHz
unuseable as a cacophony of bubbles and squeals migrates up and down numerous
simultaneous 5MHz segments. My 700W version of the APC is fine.
Hey ho
With best to all
Jim G7NKS (back to the
coil winding for VLF)
p.s. Thanks Roger for the
namecheck in this months PW
