Raspberry Pi update to buster-release to keep on running newer apps. But plain old WSPR 4.0 still runs well (had to save back an outdated gfortran-lib after the upgrade). Now I added some features to my WSPR site. Currently running WSPR on 6 m - the 50 MHz Es-season will end up soon for this year. https://dl9lbg.raspberryip.com
