[Elecraft] A KX3 Curiosity Question about ACC2 and RXIQ

[Jimk8mr at aol.com]

I would suspect the ACC and RXIQ jacks are much less used than the larger  
KEY and PHONES jacks.
 
Speaking of jacks, I'd like to repeat publicly a request I've made through  
Elecraft channels:
 
That the CW KEY1 and CW KEY2 menus have an option for "NONE".
 
That way, a mono 3.5mm plug could be used to connect to an external key or  
keyer, by setting the Ring to NONE.

Yes, I  thought that might be a reason but you can still plug in the wrong  
plug.

you will plug an ACC1 cable into  the ACC2 jack by mistake, and less likely 
that you would plug headphones into  the RXIQ jack, for example.

mm.  I understand that they are smaller but looking at the KX3  and how and 
where they are located I do not see that smaller is required for  the design.
