I want to write some software to control my AD9850 DDS source (may be applicable to your 9832 source as well Dave) and might as well include this option. >> Thanks to the reflector and a lot of hard work by Johan SM6LKM - DFCW has now been included in the PIC16F84 firmware used in the 9832 DDS. + or - Offset can be changed. Linear BPSK has also been included in hardware. Unfortunately, no computer transmit / receive programs have been found yet which can take advantage of the new BPSK feature. ( 0V = one phase, 12V = -180 degrees 6V = no output) But I'm still looking. Any ideas anyone? 73 David G0MRF
