I have been noting a consistent noise on 75 meters around 3890 where I normally listen. This bursty signal occurs every 5 minute. There are 4 bursts in succession. The power meter I have is a Schlumberger Power Meter with a DSCI module in it which I assume does TWACS. The local power company, Pennsylvania Power & Light uses this system.

This is a blurb on TWACS "The TWACS system uses the existing
power lines for data transmission, and since it modulates the waveform at the zero crossing
point, it uses the utility’s network at the frequency for which it was designed."

Although this is not entirely annoying, it is noticable. Has anyone else had any experiences with RFI from these meters ?

I live in Opelika, Alabama and we have a city power provider.  the city uses the TWACS system now for 2 years with no rfi.  i am always looking for rfi, my neighborhood has plenty.
