 No problems on 182 kHz with 800 watts into a 50 by 25 foot loop and 
neighbours within 10-30 metres on all sides. I can't recall any 
interference issues over the last 15 years with any of the other ZLs - 
most running significant output power into mainly Marconi style 
antennas.
The only 'complaint' I have had re LF operation since 1992 wasn't 
really a complaint but more a comment/query from a ham a couple of 
blocks away back in the early days- I had a 10 watt beacon running 
continuously for a few weeks on 181 kHz and had a ring one day from 
this chap to say I must have a crook  transmitter as he could hear my 
call sign down the bottom of the AM broadcast band--and what HF band 
was I on and why was I transmitting all the time anyway! An LPF fixed 
that one.

Subject: LF: RFI from 136kHz transmissions
In the discussion that I am currently having with Ofcom over the RFI
 assessment for 501-504kHz applications, the question has been raised 
as to
whether interference has been noted with nearby neighbours, etc, from 
the
transmissions at 136kHz.
