  Pardon me if this is OT, but it really has to be said often to
  enable us to get maximum joy out of using our Elecraft
  transceivers in today's world of consumer electronics (does
  that make it on topic?).

  I've been dealing with ham RFI (or more accurately, unwanted
  signal interception) issues both as a generator and as a
  resolver for about 50 years now, 30 of them with the FCC, and
  the most important thing that I would add in large letters is:

   DO NOT WORK ON OR OFFER TO WORK ON YOUR NEIGHBOR'S EQUIPMENT

  Failure to follow this advice would embroil the operator into a
  lifelong obligation to be the unpaid repair person for every
  glitch and bad-design result in the neighbor's equipment, and a
  vector for every complaint, real or imaginary, whether the
  operator was on the air or not.

  I advise my ham clients that they have three obligations:

  *  Make absolutely sure that their equipment and operations are
     in full compliance with FCC standards and their license
     authorization.

  *  Offer to be available at reasonable times to make a
     reasonable amount of on-the-air transmission tests for the
     affected neighbor and/or their repair technician to
     determine the effectiveness of any remedial actions that the
     neighbor and/or their repair technician make.

  *  Be a gentleman or lady (as applicable) in dealing with the
     neighbor because nothing will be solved otherwise.  If the
     neighbor doesn't reciprocate, do not fight fire with fire.
     It makes things worse.

  Gone are the days when we could solve most things with
  supplying high-pass filters and vacuum tube adapters with
  disc caps from grid to ground for audio stages.
