You may not have seen this comment, so I have reproduced it here:
GB3VHF (2m), GB3UHF (70cm), GB3BAA (6m) & GB3SEE
(10GHz) are always good signals into the SUWS WEB SDR, so you can check
their on-air status anytime.
Many other UK and European beacons are also audible when conditions are good.

SUWS is Southampton University, where I nearly did a PhD in 1971. This would have been with Dr Ryecroft in VLF space physics. Still, I did get to lunch with Josselyn Bell who first discovered pulsars. In the end I stayed in industry, but often wonder how life would have been had I done the PhD.
