I have just purchased a unit off e-bay called the "Universal M-400 Decoder".
It supposedly decodes POCSAG (pager messaging), AUTOR, GOLAY, SUPOCS, DTMF,
DCS, CTCSS, SWED-ARQ, FEC-A, ASCII, BAUDOT, FAX messages.

I have only been able to decode ACARS messages (Aircraft) up to now. Mainly
due to the fact that i cannot find out any frequencies for the above types
of broadcast. I have googled, but just keep getting sites which are either
out of date, not there any longer or don't have any detailed info there.

I'd be eternally greatful if anyone knows of any links to websites which
have a list of the types of broadcast listed above (both SW and VHF/UHF
etc). I do have a SW frequency list, but it's 1994 and is way out of date.
Even generally where abouts on the frequency spectrum to look would be handy
!, i just don't have a clue.

Many Thanks
Andrew
