Re: DDS-VFO reconstructed #bitx40help #radiuno #arduino #firmware


The OEM sketch for the BitX40 has a provision where it starts jumping up or down to the next tuning segment when you reach one end or the other of the tuning pot. In between the tuning is limited to a smaller range of the full band. Some have modified the pot circuitry to add push buttons to simulate end of rotation resistance values and step up or down.
