I've suggested to Wayne a few times that we should have a SPOT button that works for the Receive ONLY. IE. when you have the RIT button on, and you hit SPOT it moves the Receive RIT control to center the IF pass band. Just like it does with the main VFO now. This would allow someone to SEND a CQ, have someone answer you off your IF Center, and then auto SPOT them in without having to move the RIT knob. This would allow you to keep put with your transmitter location and then QUICKLY turn that WIDTH knob down to 50 Hz KNOWING with confidence that you're not going to remove them from your receivers IF Pass band. This wouldn't change much about the K3 at all, it would only ADD to the features it has now.
I'm not sure why anyone would want to SPOT their rig after someone has answered THEIR CQ off freq. It would just cause the both of you to either loose contact (depending how far off you were) or for the two people to be chasing each other around in circles as each one keeps tuning the other. Of course, when the RIT button is NOT on, the spot would work EXACTLY as it does now. Makes perfect sense to me.
For those that wonder what happens when the XIT button is pushed, well, it just acts like it does now, the spot will move the XIT still. The ONLY change is when the RIT button alone is turned on.. then the SPOT works like an AUTO SPOTTING RIT control.. simple, yet VERY helpful for fast tuning and filtering. For those that don't like it, well I guess it can be an option you can turn on and off, just like balance contol etc.. in the Config MENU. RIT = SPOT or RIT = NOR...
Not sure why it never made it into the list of things to be added to the rig. Seems like a pretty simple one.... Or did it? Wayne...

(My Yaesu does not allow that after peaking a signal.) Programmatically moving the result to the preferred pitch is easy to do too, since the center of the filter peak is obviously known to the software.
