There is a way to do P L tones.  I haven't done it yet, although the 
tutorial I have gave instructions. I think that while in F M mode you 
press 7 on the keypad and you can set it, I checked it out, but 
haven't used it.  Also you can do split frequencies.  When I get my 6 
meter antenna up I will be trying it more.
I am not sure about the starting and stopping the memory recording.

I just haven't used that part of the radio that much yet.
