This very message and a host of others in the archives are the very reason I own a K3 and have pre-ordered a P3. These guys listen to customer input, respond, and fix things as soon as possible!!! The P3 does NOT do what I really need in its initial form, BUT I am confident after emailing with P3's design engineer that it will, in later updates, do all I need it to do. I would never have this confidence with the major three manufacturers of ham gear!!!!!! I have been a year trying to get Icom to make one, simple firmware change to make the IC-7700 more user friendly on RTTY and am being stonewalled. Thanks Elecraft for NOT acting like that!!!!! 73, Don, WB5HAK ----- Original Message ----- From: "Dick Dievendorff" <die...@comcast.net> To: "Guy Olinger K2AV" <olin...@bellsouth.net> Cc: <r...@aol.com>; "Elecraft Discussion List" <elecraft@mailman.qth.net> Sent: Wednesday, July 14, 2010 2:52 PM Subject: Re: [Elecraft] eHam.net forum message
