Andrey, I tested software with N1MM and MixW32...Read freq from VFO (DDS) via USB port but not read setup /mode /frecv from PC. Not understand happened.... USB com is ok. Any ideea?

Hi Andrey, Sorry for long delay to reply..... My free time is very compresed . Thank you for your solution..... I am modified and put your sugestions and now all is OK. After finalizing my project I want to put normal optical encoder....Now for testing use a rest of the component in surplus an old project mcHF SDR TRX. I tested CAT interface. Work but only unisense.....DDS to PC work, via USB com used for programming . PC to DDS comnd not work.I not tested with TX and RX pin comand of Arduino module. Question: For CAT mode need use RX/TX pin Arduino module , or work only USB com? Thanks again, 73 from Tik, YO8RFS

@Relayer First, congratulations for your work! Realy nice and high efficiency. I am realized this suntez. Work very wel ... for first ON !!! Intended to use this syntez for my old TRX, KONTUR 116 ..... Is my first live .... Tested and work ok ..... But not have a ... 10 Hz, 100Hz, 1000Hz pas of frecvency.... Is posible to write a routine to change a pas of he encoder in a Menu mode ? Or push a taste ? Or other variant?. In variant FN 8 x 2 work with x 10, but in 12 taste variant not have this option. For me aplication need change pass encoder ... In many situation is practice to change pas of the encoder easy, any time. Please help if is posible .... Thanks again and mni 73 from Tik, YO8RFS
