Charles, I believe that the Elecraft Moderator has asked for this Disruptive thread "APP Roll Pins" to come to a halt.
I am not sure what point you are trying to make here.

Surprise, most of the world never hrd of these things ... and for good reason. When, oh when, will users of this junk wake up to its obvious limits and abandon the false start they represent?
