Recently Zacharias Liangas posted here about a new kind of interference, with noise spikes evenly spaced up and down the band. There has recently been a discussion on the Topband amateur radio reflector about precisely this type of interference emanating from certain new heating units and what to do about it (assuming you can find the source!). See below for more information.
