That's why you need error correction protocol.

Faster, more reliable communication.

Subject: Guide to the rec.radio Newsgroups
Archive-name: radio/personal-intro
This message describes the rec.radio.amateur.*, rec.radio.cb,
rec.radio.info, and rec.radio.swap newsgroups, as well as their Internet
mailing list counterparts and complements. It is intended to serve as a
guide for the new reader on what to find where. Questions and comments may
be directed to Jeffrey Herman, KH6O, jeffreyh@hawaii.edu, or Paul
Schleck, K3FU, pschleck@novia.net.
This message was last changed on 14 March, 1998.
History
=======
Way back when, before there was a Usenet, the Internet hosted a mailing list
for hams, called (appropriately enough) INFO-HAMS. Ham radio discussions
were held on the mailing list, and sent to the mailboxes of those who had
signed up for it. When the Usenet software was created, and net news as we
now know it was developed, a newsgroup was created for hams: net.ham-radio.
The mailing list and the newsgroup were gatewayed together, eventually.
Over the years, as the net grew, the volume of discussion became
progressively higher. First one by one, and then as part of two
reorganizations, what was once one group became many. In the process,
developments elsewhere on the net were reflected in the groups as they were
created, most notably the change to place all of the ham radio groups in one
hierarchy.
The collection of newsgroups continues to grow as more people join the net,
and as more topics of discussion gain volume, I expect to see more groups be
created as well. This follows what is happening on the rest of the net.
Nearly all of the radio newsgroups have corresponding mailing lists, the
notable exception being rec.radio.swap. There are also a few mailing lists
that don't have newsgroups.
The Current Groups
==================
It's important to post messages to the group that's appropriate for them,
and not to the groups that aren't. The whole idea of having different
newsgroups is so that folks who aren't interested in, say, homebrewing,
don't have to wade through messages about homebrewing on the way to read
about Field Day. Posting appropriately is just good etiquette.
The rec.radio.amateur.misc group is the catchall. It is what rec.ham-radio
was renamed to during the first major reorganization. Any amateur radio-
related message that's not more appropriate in one of the other groups
belongs here, from contesting to DX to ragchewing on VHF to information on
becoming a ham.
The group rec.radio.amateur.digital.misc is for discussions related to
(surprise!) digital amateur radio. This doesn't have to be the common
two-meter AX.25 variety of packet radio, either; some of the most
knowledgeable folks in radio digital communications can be found here, and
anything in the general area is welcome. The name was changed to emphasize
this, and to encourage discussion not only of other text-based digital
modes, such as AMTOR, RTTY, and Clover, but things like digital voice and
