I have found this interesting project:
You need only a shortwaveradio and a computer mit sound card.
I’ve been following RadioGram for years, it’s a great project. It used to be tx’d on VOA transmitters until Kim Elliott left, and now it’s transmitted on a number of TXs, - It used to be transmitted from a TX in Europe at one point, which gave a decent signal in the UK - You can probably get it on one of the backbeams of the current schedule.
Download FL-Digi and you’re good to go
