Rob, True, but, for example, I can do that on my 756Pro2 and it is often I want to in a contest. For example, if I have narrowed the filter settings to pull out a weak one and want to go back to a normal wider setting, this is something to do while the computer is sending the next CQ. Now at least we can clear the RIT while transmitting, which is helpful. The Pro2 allows you to adjust just about any RX parameter while transmitting, and I find that extremely useful. I've commented on this issue since first getting my K3 in 2007. 73, andy, ae6y ----- Original Message ----- From: <k...@baymoon.com> To: "Guy Olinger K2AV" <olin...@bellsouth.net> Cc: <elecraft@mailman.qth.net>; "HA3AUI" <ha3...@ax.hu> Sent: Thursday, April 01, 2010 9:28 AM Subject: Re: [Elecraft] disabled controls during TX
