No because the project emphasizes AM, an old spectrum-hog mode
which ought to have been retired about 1965.


Why? AM is a legal mode, with advantages and disadvantages.


AM is a relic, inefficient in it's use of spectrum, and inefficient in
it's use of power (only half of the transmitted power contains
intelligence and half of that half is discarded at the receiver!).

But some hams still like to operate AM, nothing wrong with that.


And my 1931 Model A Ford is "inefficient", but I still like to drive it!

Been there...

Works well, does the ladder line dipole.


;^). Then (shudder) things with tubes!!!!


You mean "hollow-state"? Oh yes, a good technology. Old, but with many
advantages.

I agree. I've been learning a bit about them, and am pretty impressed.


Room for Morse CW, room for A.M. IMO.


And PSK31, SSB, RTTY, SSTV, etc.

Speaking of "room"....

One thing about amateur HF/MF AM operation that seems to
be quite different is the "old buzzard roundtable" type of QSO.

What happens in such a QSO is that several stations are on the same
frequency, transmitting in a round-robin sort of sequence. A
transmission may be 5, 10 or more minutes long. Each op gets to do a
serious monologue on whatever subject interests them. What makes the
difference is the ability of the speaker to be interesting to the
audience, and communicate verbally in a way
that is enjoyable. It's a developed skill, and some AMers are really
really good at it.

I was listening to one of those last night on 160. I don't think it is
anything I would like to do, but those guys seemed to be having a good
time..

Yes, it could be done on SSB, but it's not as common.

If a bunch of hams are all using the same frequency, rather than being
spread out all over the band, isn't that spectrum efficiency?

IMO.

Another good thing about AM is the publicity factor. Ask hams who were
licensed before about 1965 or so how they found out about ham radio,
and a high percentage will tell you they started out with some sort of
"shortwave" receiver, and came across some hams using AM. Listening to
the conversations got them hooked.

When SSB became the dominant amateur HF/MF voice mode, that method of
recruitment dried up.

Heh, all that is before my time, unfortunately. But I can see where
that *would* get people interested.
