Greetings, Thank you for all the great work on creating and improving WSJT-X.
You are probably aware of the ADX transceiver designed by WB2CBA. It is a simple open source digital HF rig designed for home brewing. We are working on replacing the Arduino with a RPi PICO. Due to differences in internal peripherals and timers, it is more complicated to measure the TX frequency in order to send it to the Si5351 DDS we use. In rethinking the problem, it occurred to me that WSJT-X must first generate a digital list or table of tones for each transmission before they are sent to the sound card and on to the rig as an analog signal. What would greatly simplify the transition to PICO is if the TX audio frequencies could be sent out over USB in a directly useable format that could be directly added to the base frequency and on to the DDS. The best solution for ADX would be the final 0 to 3000 Hz tone frequency value be sent upon start of TX and each subsequent change in value or at a preset interval until the end of TX (stop value appended to release TX mode) or some other system if it is easier to implement on the WSJT-X side. Timing would be controlled by the WSJT-X. We have been using VOX or CAT control for PTT, but could update that to CAT only. In addition if USB CAT polling interval requests could be blocked during TX periods, that would be even great as it prevent dropouts and data conflicts if using a USB hub with audio dongle. 73, Alan AG7XS _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
