From the good folk at Radio Free Redoubt, this PDF explains how to listen to PSK – a very interesting, and in case of emergency potentially very important, amateur radio digital mode – with a receiver with some earbuds, a computer with fldigi and a piece of tape.
The PDF is “Popeye’s” article with the comments distilled into an paragraph appendix.
Of course other PSK software will work. The fldigi selection is solid and it is available for a lot of platforms.
This works – at our club we’ve done a demo doing it this way, including adding the other link between the computer & in our case transceiver to do the transmit side.
The technique fits very well with the Freecom idea of personal preparedness.

Tuck this away for rainy day. It is worth downloading the fldigi program mentioned, as a “just in case.”
Of course you can try this now too!
