[Elecraft] PX3

I'm not sure it's a question of PX3+KX3 OR computer+KX3.  A computer can
still be connected to the KX3 (via the PX3) for use with logging / control
programs.

Elecraft needs to update the PX3 datasheet.  The PX3 is now much more than
just a panadapter.  

In addition to the spectrum and waterfall display, the PX3 supports up to
335 text characters ... 201 characters of received (decoded) text and 134
characters of transmitted text / text to be transmitted.  The PX3 can
receive text and buffer text to be transmitted at the same time.  The PX3
can store up to 50 text messages and 50 macros (PX3 and/or KX3
remote-control commands), each up to 95 characters.  Each messsage / macro
can be assigned to a keyboard key or key combination (with Shift, Alt or
Ctrl).

The current PX3 beta firmware (MCU 1.42, 3-22-2016) introduced a
"scratchpad" feature.  This is yuge!  The scratchpad feature allows you to
enter the other station's callsign once and substitute the scratchpad into
stored text messages using "\s".  This is analogous to the HRD / DM-780
<his:callsign> tag.  Yuge!

I'll take this opportunity to share my (ever-growing) PX3 Wish List.  Mouse
support is trivial given the existing keyboard support.  Logging support
will likely require a new (internal) "option board":

• Alternative to Insert Key and Ctrl-Insert Key Combination with Scratchpad
(e.g., Alt-i and Ctrl-i)
 - Some keyboards don’t have an Insert key
• Marker and Center Frequency Display with 1 Hz Resolution
• Mouse Support (e.g., Mouse-n-Click QSY)
 - using a single 2.4 GHz wireless dongle which supports both the keyboard
and mouse
• Logging
 - assumes a new memory or microSD (preferred) "option board" connected via
the existing PX3 SPI or I2C expansion interface
• Message Tags
 - recognize an optional tag at the beginning of each message (e.g., "<qth>:
Plano, Texas")
 - expand <tag> (non-recursively) in other messages
• Automatic Callsign Recognition
 - regular expression:  ^([BFGIKMNTW]|[A-Z0-9]{2})[0-9][A-Z0-9]{0,3}[A-Z]$
• Remote Control Commands
 - #UP/#UPB marker move up
 - #DN/#DNB marker move down
 - #MAC macro read/set
 - #MSG message read/set
