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.
