topfiles.txt 12/03/95
The LWCANews ftp site contains files relating to longwave radio
monitoring, natural radio research, and longwave and medium wave low power
experimental operation (under FCC Part 15 and equivalent Canadian rules).
These are some of the topics of interest to members of the Longwave Club
of America, covered in the club's monthly journal, The LOWDOWN.
These files have been gleaned from the Longwave/Part 15 Bulletin
Board System. Because of size limits on this ftp server, we can only
include a limited sample of the BBS library here. There is no charge for
using the BBS, other than the telephone call. The details: 8-N-1, up to
9600 baud. The number is 706.672.0360.
Program files are mainly for PC-compatibles since we don't have the
means to test other kinds. However, we try to make text and picture files
as widely useful as possible. (Some improvement remains possible here.)
DOWNLOADING: Remember, this ftp server follows Unix procedures. Among
other things, this means directories and filenames are case sensitive. We
have named all files on this server in _lower case_ letters, so if you see
a file listed below in upper case, that's accidental.
This listing contains the filename, size in bytes, the date the file
was uploaded, and a brief description. Here they are, by directory:
