TiVo for your radio...

[Peter Murray]

sorta.

Have a look at the "Radio Shark". This is a USB-connected device that 
enables recording of FM and AM radio. PC and Mac compatible.

Allows buffering of live audio, so one can repeat the last few 
sentences, last song, hour, or more of the program to which one is 
listening. Additionally, it can be set (like your VCR) to record a 
particular program (by time, date, duration and frequency - there is no 
program guide information).

Not selling, just thought it was of interest to the group (though still 
of no help to those of us so far away from WJIB).
