Background - roof mounted F12 C3S, 100 wts in downtown row house. Not
on air much - casual DXer (310 DXCC). Neighbours have telephone RFI, so
do I. TVI as well - mostly channel 3 and videotapes - everyone on cable
with VCRs. Decided it was time to fix things up - neighbours tolerant
and I get off air (even when in the pile for a new one) when asked.
But, the countries are getting a bit harder and teenagers expect
continuous telephone availability.
I eliminated my telephone RFI by grounding all spare conductors and
putting .001 caps from each side to ground at the entrance, plus and 10
#43 beads on one phone cord. Problem is that the long distance ring
(Morse D) wouldn't fire and wouldn't trigger voice mail - local single
ring OK. Removed caps, ring now is OK and of course, RFI is back.
Ideally, I'd like to give the neighbours the plug-in modular filters -
enough for every phone (say 5/house). At $30-40 CDN each, is there a
less expensive way?
For the TVI - is there a high pass coax filter (ideally male-female to
put in the CATV line)? Yes, lots of cable ingress/egress - 2m and CATV
channel 18, pagers on channel 17 and 21.
Any ideas appreciated. tnx 73, George VE3YV / K8HI
