Many folks are using the sketch by Allard, PE1NWL.?
He has done a great job on the code and documentation for this and it has a lot
of very useful features including dual VFO, RIT, SPOT (or fine tune for SSB), CW/USB/LSB
so I suggest you check it out. This code is completely backward compatible with Farhan's
original code so it can be loaded into the Raduino without any hardware changes. However,
to take advantage of the added features there are a few simple mods that are needed but are very well documented.
The code and all documentation ?is in GITHUB at :?
