You would be surprised how many old timers and experienced CW ops are
using digital modes. I think that even in this no-code world, almost ANY
ham would at least RECOGNIZE CW, even if they couldn't copy it, but I'd
bet that very few CW or SSB ops who don't work digital modes would
recognize any of them as being signals, let alone recognize the mode.

Hi Carl,
It'd be just great to hear you on Topband with that 210 rig...
As for garnering W.A.S. during the QSO Party, I should forewarn you:
historically I don't think ANYONE has EVER netted 60 (or more) QSOs during the
entire two-weekends of the event! The west coast is only now beginning to make
its presence known in the past few years in the person of Steve
(VE7SL---forgive me if I have your callsign incorrect, Steve). Most activity is
from the north-eastern USA, although there IS a VERY strong contingent that
joins the group from the mid-west.
No matter, it's a laid-back, leisurely, fun exercise, & it'd be nice if you
could join the fray, Carl.

Tom, "on point" ....... I am, almost exclusively, a CW and Digi op in that
order. I will say, anecdotally, that I have not experienced any interference
caused by one or the other to the other on 160. I admit that I am not THE most
active op on 160, but I am there a fair amount of time.
Since most 160 band plans, like the DX window, seem to have gone by the
wayside, it would be incumbent upon us as those who love the band, to come up
with one that includes the newer modes. The reason? Better utilization by
those who have WAY LESS than optimal stations for 160. Particularly those who
are antenna and power limited. With the advent of modes like JT65, this has
been a godsend for the apartment dweller or those who live in a yard-nazi
environment that makes it virtually impossible to put up anything larger than a
mobile whip. Ask those folks about JT65 and they practically bow to the
software writer as being the savior of their operating.
Having said that, I think there is room for all who want to try to operate 160
(not really that many people out of the whole ham population, truth be told).
Digi modes make it possible for those who have that intense desire but lack the
room for antennas that are anything like what we would call decent. WE just
need to come up with a plan and get some of the 160 heavy hitters to endorse
it, right? We cannot hold back digital progress, but we certainly can come up
with plans that work...... My opinion, but there it is. We should try to
include everyone we can.
If it were only up to me, I would ban SSB from any band that has less than 300
khz total space available. It takes up way too much room for the intelligence
it conveys. BUT.... I am not the gawd of ham radio and must tolerate its
presence on bands like 160 and 40, both of which have band limitations (size
and/or broadcasters interference which makes the bands effectively smaller).
Not wanting to start a flame war about SSB, just mentioning my own personal
usage prejudices....... And that really IS one of mine. Like I said early
on..... CW and Digi for me. Phone belongs on VHF/UHF...... LOL.
So whaddaya guys think? It really IS up to "us"........ The users and lovers
of 160 ( or any other band for that matter). I find CW and DIGI ops to be VERY
cognizant of each others presence and have rarely seen intentional interference
between those two...... Except when digi ops stray below the "digi borders"
into the 20 meter CW portions..... At which point the CW ops lay a carrier on
them to get them to move. I do 't believe I have seen it go the other way.....
But I am sure it has on occasion. Since both modes are definitely "space
saving" and very efficient, I think there is room for all....... As I seem to
have stated in this lengthy tome.

You got that right Herb, I have never heard it on let alone work it.Greg
I wonder if anyone here knows N7CQQ or N6XT and can convince them how rare
American Samoa is on 160 meters.? They probably can't do much from the
Tradewinds Hotel but from the AH8LG "QRO" station it might work well enough to
get some of the faithful a contact from AS on TB.

Every experience will be different because of geographical location, antenna
and equipment, noise floor, and operating habits.
Proper frequency planning requires understanding potential problems and how
to handle them, not pretending if everything works perfectly and appears OK
at the moment, it will always be OK.
Again, a good thing to consider is Collins. They assumed running a clean
audio tone into the audio of SSB transceivers and transmitters was a good
way to generate CW, and a good system to release into the field.
They must have assumed carriers were always balanced, there was never
harmonic distortion, and there was never hum or noise. They probably assumed
equipment would always perform like new, and always be properly operated.
They got bit pretty hard by that. The lesson from that should have been
audio injection of tones produces a limited signal-to-distortion ratio and
is subject to equipment and operator malfunction.
If It goes in the front of a SSB bandwidth system, it should be treated as
SSB bandwidth for distortion products.
Yaesu, for a more recent example, generated an almost square rise and fall
waveform CW signal and processed it through a SSB system as a CW signal. The
filter BW used was a few kHz. If they didn't waveshape properly later in the
system, they should have ran it through a CW filter.
There is also a problem with NDB harmonics on 160. This is another case of
poorly engineered systems that depend on perfect linearity to prevent
interference. For all who think low level modulation followed by linear
stages is a good system to prevent spurious, we can find many examples where
that assumption caused problems. I can hear some 5th and 7th harmonics from
25-50 watt NDB transmitters from over 1000 miles away, and getting them
fixed is like telling a digimode guy he has an issue with spurious.
This isn't a new, or unheard of, engineering problem. I would think Hams in
particular would be more in tune with proper planning that considers less
than perfect systems.

The real concern I have is growth in popularity of multiple modes that all
go into a SSB transmitter audio channel, and that are all dependent on
virtually no distortion or noise to maintain modest quality.
An example I would use for this is PSK31, where many users almost lynch
other users who run more than a barely discernable signal. While the blame
is placed on amplifiers, the root problem is very limited dynamic range of
the system. Because it is so difficult to keep distortion and spurious TX
levels down, and because receivers often pass much more BW than the desired
signal, they decided to make everyone stay somewhat close to noise floor.
Like a used car dealer would do, limited dynamic range is presented as a
"feature". Saying "No one needs power or good antennas because the mode is
so efficient" is a good way to mask issues caused by amplitude changes in an
audio tone driving a SSB transmitter, and using a wide SSB channel in a
receiver of a narrow band signal.
You won't find many CW operators who think 2.7 kHz IF filters followed by a
31 Hz wide audio filter is a good system for dynamic range.
As audio into SSB transmitters and back through SSB receiver modes become
more popular, it will be tougher to keep a *lid on shortfalls*. There also
won't be a *shortfall of lids* (intended as a pun) who mis-adjust things, or
wire things wrong.
Ask yourself this...
If digimodes get more and more popular, where will they expand if we start
them smack in the middle of what was a weak signal area? Does anyone here
really think the best place to have started digital modes was in the middle
of the most popular DX weak signal area?
Or are we really just pretending 1835-40 was a good idea, and there will
never be more than 30 operators using digital modes, all QRP, and all with
perfectly adjusted radios?

Both KH8 and 5W are somewhat rare on Topband.
Looking back in the log I see the following:
KH8/N5OLS (1996 and 1997) and KH8Q (2006)
5W0VF (W7TVF in 2001)

With so many skilled ops descending on Am Samoa for some R and R I hope that
one of them would enjoy some TB operation putting a rare one on the air.
