Here in the Netherlands we have al least 3 "new" QRM sources of "the 3th kind" - elevators (electronic motor controls) - solar cell control units - thermostat control of central heating systems (not sure on powerline communication) QRM / QRN noiseblanker would be fine ;-) groeten Peter petervn-at-hetnet-nl pa0pvn-at-hetnet-nl pa0pvn-at-amsat-org only large files: pa0pvn-at-gmail-com There are 10 kind of people, those who can count to 1010 on their fingers, and those who count to 1111111111.

I think this is our first report of elevator noise. :-) Perhaps we can someday have an ENB (Elevator Noise Blanker). Something to go with the WPIB (Water Pipe Interference Blocker).

It has been tracked down to elevator noise. My landlord put in a new elevator in the summer and now I'm receiving exactly what you described. This is not a Flex problem in my view. I've been told by other ham operators that the new elevators need to be installed with a filter. I have yet to approach my landlord as I am just glad that he lets me use the roof. My problem occurs on 40 and 80 meters. I hope this helps.
