Hi Mal.

Ok you are b= ang on the line limit.

Yes the filters a= re fitted. I know how the system works as you describe it. Since the common denominator is the=A0copper line I thought the RF would effect both.

Hi Mal.

The telephon= e portion is speech in the standard 300Hz =96 3400Hz speech band directly on the copper pairs, the DSL sits on top of this using the DSLAM in the exchange, that is= why you have a =91Micro Filter=92 at each telephone outlet in the house, do you have a =91Micro Filter at each telephone outlet?

Normally it is no= t a problem with CW, SSB, or QRSS it is just a problem with Opera because of the data base feedback facility

Hi Mal.

I had the sa= me problem until I went Fibre To The Cabinet (FTTC), if you are on a long local line especially if it is overhead, the most likely there will not be any DSL carriers above 500kHz, and what are present will have a very poor S/N ratio= . I fitted common mode chokes on every piece of cable I could find and they mad= e no difference, only a few watts at 500kHz and the lower HF bands would cause t= he DSL router to drop out and re-train up. I had my ex (pre-retirement) collea= gues =A0from BT Adastral Park, conduct measurements on my local line, (2.8km in length with 30m of drop wire) as part of a national survey, the line withou= t the common mode chokes had no DSL carriers above 500kHz with an S/N less th= an 10dB, with a few watts of TX power with and without CMCs the remaining carr= iers were degraded sufficiently to cause the router to retrain. Another cause co= uld be if you have drop wire there could be corrosion on any external screw terminals causing =91Rectified Joints=92 like the rusty bolt effect on radio masts, water getting into older types of drop wire can cause corrosio= n on the plated steel conductors.

Hope this he= lps.
