My 481 THz test software and lead are my priority. When I did the optical tests way back more than 10 years ago PCs had separate mic and headphone jacks. All my PCs now have combined jacks!
So, I have to interface my optical RX and the PC in a new way. With soldering skills very hard these days, this requires some thought. Years ago I would just have bought a new jack socket (with mic input) and just changed the plug! I think years ago I just used a lead with standard 3.5mm plugs at each end.
I may put the 10m WSPR beacon on too.
UPDATE 1038z: 10m WSPR beacon is ON and my audio setup (interface from 481 THz RX to the PC) is working with Spectran. At G1KQH's suggestion I used a USB sound card I already had and it worked first time. Thanks for the suggestion Steve.
UPDATE 1144z: No 10m WSPR spots of my 500mW beacon. I suspect things are very disturbed. I checked all was well on another RX.
UPDATE 1515z: 4 stations have spotted me today so far on 10m WSPR. My 481 THz TX beacon and RX work with QRSS and Spectran.
