[hpsdr] Setting freq on PowerSDR.

[John Melton]

The advantage of having the Arduino as a CAT serial port is that the 
application (PowerSDR) does not have to have focus for it to work. Also, 
it is so easy to send CAT commands over the serial port interface.  The 
code can be used as a base.  The number of buttons and step encoders and 
their functionality is up to the user.

I have recently added an additional button (with a red cap) that is used 
as the PTT button.  It simply sends a ZZTX1; CAT command when the 
pressed and a ZZTX0; CAT command when released.

The most complex commands are the ones to increment/decrement the band, 
mode and filter as these can be changed on the radio using the GUI.  I 
simply send the command to get the current setting and when that is 
received either increment or decrement the value based on whether it was 
up or down (allowing for wrap around).

These really are so easy to build and code.
