si init OK / tx OK /ready OK / tx OK but then NOCTS follows

[zanco]

Hi,
I assembled a Pro Mini and the SI4463 board together. The serial console gives the message as in the title but no CW is transmitted. I expect to see it on 432.400 MHz ( + or - some kHz) but on the SDR with 1 MHz bandwidth no signal shows up.

I did read the part about the radio_config.h but I assume that if for testing I am fine with the frequency and power I can use the radio_config.h which is in the src\si4463\radio folder ?

Any help on this ?

Thanks,

Please be sure that your chip has a revision "B1".
Next you have to prepare your own "radio_config.h" according to steps from following link

The radio_config.h from repo + 26MHz XTAL must produce 432.400 MHz

Hi Alexander, thanks for your reply. Caught by the flue it took me some time to react. Sorry

Tonight I succesfully prepared my own radio_config.h for 144.3375 MHz . I completely forgot to change the GPIO settings and to use the "Direct TX" project setting. So it made sense that the unit did not start with TX. I have a chip revision C2 with 30 MHz Xtal and that works OK.

Do you happen to have an RTTY (FSK) example laying around ?

Thanks,
Ben
