Our "class action" vehicle, as was already pointed out, is the ARRL. As
part of their charter to protect our spectrum and represent their members
in all aspects of the hobby, they need to step up to the plate and take
charge of the Solar RFI problem. They, in turn, need to (1) contact
offending companies, and (2) pressure the FCC to become aware of the entire
noise level problem and start enforcing their rules.
