For Expert Village, I'm Kurt Glaser, N7QJM. The last piece there was really great, we
had a fun QSO with Tom and it definitely shows you several things that you can be doing on
the amateur radio; 1. Having a nice conversation or QSO, 2. There are certain protocols or
etiquette that you can actually use. When we exit a conversation, basically what we
do, is we end the call again with our call letters and we'll usually say 73's, which
means; kind of, a good wish, good commendation, so long, see you later type of ending of a
call. That's actually how you end a QSO or conversation where you typically talk and
everything have, of course, it's own little symboligy and this is called rag chewing,
or talking back and forth telling about your lives, so on and so forth. That's how a QSO
goes. I also want to give you a demo quickly here as to the other types of signals that
are used on the amateur radio bands. We're going to stay on the 20 meter frequency right
now and expose some of these other types of frequencies. Excuse me, not frequencies but
other types of signals that are used. There are digital signals, there are FM signals,
there are single side bands signals, as well, and then there is CW or the little continuous
wave signal. Right now we also are going to look at facsimile signals, and hopefully give
you a quick listen for a few seconds on that so you can recognize what that sounds like.
Let's try that right now. That's a facsimile signal, right there, that's going back and
forth. You can send and receive facsimiles across the amateur radio as well as slow scan
TV. That can be done as well. Let's see if we can pick up one of those next. Slow scan
TV, right here. It has that oscillational type of sound. You can hear it. That's slow
scan TV. We also have Fm frequency as you can see right in here. You might be able to
see that part right in there, probably not, but at this frequency range you also have
FM frequency modulation broadcast. "N7QJM broadcasting on FM, anybody out there? C-Q,
C-Q, C-Q from N7, Queen, Japan, Mexico on FM. Over." It doesn't seem like we're picking
up anybody but that's the FM frequency. The other thing is that the chart that we showed
you a little while ago, the colored bands on that, you can also find those online, which
basically gives you the frequency bands that you can be using and tells you what type of
signals that you can send and receive in those portions of the amateur radio bands that you
operate with. That's does it for this section. Join us again next time for more adventures
on amateur radio; this is N7QJM, 73's.
