40m VDSL filter for your NBN (FTTN)

 Geoff VK2WA  pointed me to a blog posting from Andrew VK3FS

for filtering the VDSL signal hitting 40metre band for NBN FTTN connections.

A 40m VDSL filter to stop Internet drops. Works with TP-link Archer modem
 

I having the same plus more, not so much noise  eminatiing from the VDSL mode, but my RF crashing my VDSL, 

but first, the trick I did to crush the RFI radiating  from my VDSL connection and  my VDSL modem, I just add some clip-on  ferrites cores on the VDSL cable as it popper out of the wall heading to the VDSL modem, I just added the camp over ferrites one at a time, each time checking the internet download and upload speeds, I was getting 55Mbps download, for a 50Mbps NBN service, I hit a point where the dowblaod and upload speeds dropped, then removed that last ferrite, returning to a 555Mbps download and 19Mbps upload> now I could not detect any RFI from my VDSL FTTN service. 

Next problem,  crashing the modem, if ran on any HF band,  I only needed 5watts  to reset the modem, from any HF band,  so I started adding ferrites on the cables coming from the modem internally,  winding multiple turns on large size clampon  ferrites yielded good results, now I can safely run 50w on Tx on any HF band.  To improve on that, if I isolate the internal copper pair wiring within the house I can then run the 100watts.

End of 2024, full FTTP arrive in our street, just a matter of switching over to FTTP service to see what happens then.
