Morning Thomas,

Looks like our Prayers have been answer! 160 – 10, 5 Watts, single side band using a new transmitting technique , no more DSB!

All for 80 bucks (includes 3 band modules)

The v. III version debuts a novel firmware scheme for our Si5351A/MS5351M VFO which allows a move away from DSB transmission to SSB, by a new process we are calling AFP-FSK (Audio Frequency Processed-FSK).

Brilliant, Pete! This looks like a fun kit to build and certainly an affordable way to hit the digi modes! Thank you for sharing!

  1. I just ordered the kit yesterday and cannot wait to build it. I would love an enclosure and asking a friend to help make one out of sheet metal.

    Does anyone produce a 3D printed enclosure already ?
