--- Quote from: kitz ---That specific type of HAM masking isnt something that Im aware of that is in use by any of the UK ISPs (BE did a total block rather than the U-interface mentioned in that document).

lol... that was over 3yrs ago. I cant remember what I had for dinner most days :lol:
haha I do recall though that the tones were in a similar region and they were I think using the same equipment.

On target SNR margin 6 dB I have now 19215 kbps instead 15000 with HAM PSD mask.

Just as a matter of interest, my modem now notches itself when I use 1.8MHz
What I have had to do is to put a common mode choke on the incoming line, just 9 turns around a FT240-43 ferrite core, before that eveytime I went on the air it killed my modem stone dead with just a few watts, now I can run 100W without any problems. It's also cleaned up my connection somewhat, which is nice.
JGO:
Congratulations Octal ! Someone who appreciates that there are grades of ferrite with different RF properties.
