[Elecraft] HB "button box" for K3

[Brian Alsop]

I really miss extra programmable buttons on the K3.  To remedy this, I 
created a "button box" that has 20 programmable buttons.

It's pretty elementary with a 4x4 keypad and four push buttons.  One 
PIC, one voltage regulator and a MAX232 for RS232.  All buttons are 
in-circuit programmable.  Things I really wanted on one button were 
SPLIT+1, SPLIT+5, UNSPLIT, PSK, FSK, modes and bands.  Sure there are 
other ways to get there.

Now for the rub.  It can be directly plugged into the K3 but one would 
loose all other functions that use that port.  Instead I use LPBRIDGE 
which allows up to five virtual ports (applications) to use the single 
K3 RS232 port.  VSPE is used to bridge the real RS232 port to a virtual 
one for LPBRIDGE.  I use LPBRIDGE all the time anyhow so no big deal for me.

Nothing original.  We will see how "needed" it really is in time.
