This the normal sbitx software with audio injector card and si5351. Have two ad831 mixers and a 10.7mhz 30khz crystal filter.
To rx clock 2 goes to first mixer and bfo goes to 2nd mixer. Sound output from the mixer goes to the sound input to sbitx software.
?
To tx clock 1 bfo goes to 1st mixer and clock 2 to 2nd mixer. Audio output from sbitx sound card goes to 1st mixer, same input from antenna in rx. The antenna is switch to the output of the 2nd mixer.
?
To do the clock swap and antenna switching im using two small relays.
