[Elecraft] K4 Features and current K3+

A feature that should be included in the "K4" is a software addition that will allow one to
send digital via the rear audio in connector while operating USB (upper sideband) with the
front mike.  I use the current K3+ on AirForce/Army Mars.  I need to be able to switch from
digital (M110A) to voice on a moments notice so can not use the digital modes.  The mike is 
hot while transmitting digital.  Most mikes leave the mike element hot.  The PTT is a SPST
switch.  This means that you have to be careful not to have any noise in the shack while transmitting
digital.  If there is a way on the K3, service was not able to point it out.

That's in addition to three USB-A ports, true RS232 via DE9 for legacy station interfaces, full analog audio I/O, HDMI, and the usual ACC jack. It's a superset of the KIO3B.
