This is actually an important topic, since our own
installation, or that or our neighbours may have an
impact on operating.

To clarify Dave's point, the service provider ownes
the first point of attachment in the home, so only they
can legally replace this for an ADSL suitable interface
(even assuming that you can get one).

In my case, the ADSL entered the house via an overhead
line, and then crossed within the outer area of the
loft to the interface box. At this point it was within
15 feet of my G5RV which I occasionally used on 136KHz.

What you might be able to do on your own installation
is to put the ADSL router on the house master socket
and then put a low pass filter in line with the
telephone connection to the rest of the house. Presumably
you could use one of the socket filters to do this.

(only BT here in

the UK offers "engineer assisted" as they own the "local loop").

But they don't own the house wiring, do they?
Any good reason why you cannot install an 'engineer assisted' wiring
arrangement yourself, John?

 Here in ZL the 'engineer assisted' variation is one option- the other being
DIY-however and whatever you want-any and all resulting problems with either
service being yours to deal to as well!
 Naturally the recommended method is to replicate the 'engineer assisted'
installation but not all bother.

Just before I left Telecom NZ a month or two ago I had been carrying out
extensive testing into the vulnerability or otherwise of ADSL- believe me,
it is VERY robust, especially downstream. I expect your main problem at 136
kHz would be related to the susceptibility of the ADSL modem in the general
EMC sense, rather than any ADSL specific issues.
