My home brew digimode interface still makes fldigi and WSJT-X act up. I guess I'll have to debug it again, this time focusing on the UART to USB converter. I'm this close to buying a digimode interface but I'd really prefer to build at least some of my stuff myself. Then, again, I could also imagine myself operating for a change. #firstworldproblems
For testing, I replaced the sound card in my digimode interface with a different type and it seems to work like a charm. Maybe using a USB sound card for like 2 EUR wasn't that good an idea.
@dl4mat Not sure if this is useful but I've been using WSJT-X with a Sabrent USB adapter (https://www.amazon.co.uk/gp/product/B00IRVQ0F8) hung off an unpowered Anker hub (literally dangling in space atm!).
It has been fine for a couple of years (on a Pi) + It uses the bcm2835 driver.
@dl4mat I do wonder how many people have followed a guide that said "it's ok, just get any usb thing off eBay" and then had this issue
