when you said this "and the other noise that attaches itself to my signal on 14Mhz" this peaked my attention, for a long time on 160 metres if I transmit there with a digital signal of any sort I get after a few minutes a carrier that sweeps slowly back and forth across my TX signal. If I wait for 5 or more minutes it then stops its sweep and goes away. if I fire up again, particularly on WSPR then this sweeper comes back. The longer I transmit for the closer it ends up to my origin frequency. Is this anything like what you are experiencing on 14 MHz?
My noise is different to this,I have 2 noises .I have wide band noise, across the spectrum ,which is like white noise at around S7-8 up to around 18MHz , this is what I believe is vectoring noise , could be higher but don't have a resonant antenna to get accurate readings any higher. I also have another more annoying noise ,that sound similar to the radar ,only at a much higher rate ,and as soon as I transmit ,it is on my transmit frequency ,and can be 60KHz or more wide ,and very loud . I posted an image a bit earlier in this thread showing this noise .I can't upload a video of the noise , on this forum unfortunately .

I have had the NBN techs out a couple of times ,and they went around the neighbourhood with their RF leakage detectors and fixed a few bad connections, dropped my noise about 3db. They actually disconnected the the cables around the corner from my house , so there was no signals present on their lines ,and my noise remained the same , a check of the area with the RF leak detector and with my portable transceiver and DF loop ,found that there was still a noise being generated and running up some cables going up the pole outside my neighbours house . They say that they are connected to the Optus telephone cables strung along the street ,although with NBN our phones are all over the NBN and not overhead wires .So the saga continues , I am now trying to get Optus to send a technician and not just an installer out .
