Now I have broadband up and running (a doddle!) I can now listen properly to BBC7.
BBC7 is one of the new 'digital' stations operated by the BBC, and is available on DAB, Freeview and via the internet.
streaming audio is available on the websites for each of the different 'Digital' stations, but on a dial-up connection, this isn't really practical (the streaming is via RealMedia and it keeps buffering the stream, leading to silence!)
The big advantage on the BBC 7 website is the "Listen Again" feature - there is a page devoted to an entire day's schedule, and you can listen whenever you like up to 6 days after original broadcast - if you have a fast internet connection, this works rather well, and the sound quality is pretty good (at least, it is through my PC speakers!)
Most of the other digital BBC stations are devoted to music, but BBC7 is the 'Archive' station, and is full to the brim with old BBC drama, comedy and book readings - the rule being, as long as it has been repeated on the analogue station of origin, or was last broadcast more than three years ago, it can appear on BBC7 (subject to the usual licensing issues)
For an old-fashioned spoken word radio fan such as myself, the station is a godsend - Round The Horne, The Goons, Hancock, The Masterson Inheritance, I'm Sorry I'll Read That Again, Sherlock Holmes, Discworld adaptations, all are (or have been, or will be!) broadcast on BBC7. (No news breaks or advertising either, though there are sometimes some lengthy 'trails' for other BBC7 programmes)
If you have digital, check it out; if you have broadband, try out the BBC7 website
