Sounds from the past

Clearing out some old USB sticks took me on a tour of some of my old HRD sound recordings.

Here's a brief one of an EU station calling CQ on 12m aurora, followed by a much longer one, with far less auroral warble:

And here's one of OX5T and stations calling him warbling very nicely on 20m:

And, before I subscribed to a 4G internet service, some remarkable RFI from an old microwave router/transceiver that we used, with very poor service, in the days when the Welsh Government paid "up to £1000" to companies to provide solutions in remote areas.  Accordingly, we all ended up with rubbish services, each one costing the taxpayer, surprise, surprise, a few pence below £1000!
