I think Patrick's suggestion is wonderful. I think especially the idea also
presented that we add our power level to the normal Grid Square. It would
really reinforce the mandate from the FCC rules that we should only be
using the minimum power required to affect communications.

Sounds interesting!? How about (for the day) we add our transmitter power to
the exchange, for example "FN03 100mW".? It will help reinforce the concept
that only minimal power is required.

I am sorry if I offend anyone, but "*5W or less, ideally using HTs or
portable setups & handheld directional antennas or **whips/duckies*" is not
*experimental* al all. It is standard operating mode for a lot of people. I
hope we can up with something truly experimental.
Otherwise please call it "QRP, portable Wednesday" because that's what it
is. Nothing more.

OK call it something different than experimental but I still think it's a
really good operating idea. I remember on AO-51 often times when they turned
on the second FM channel, they encourage QRP or low-power operation.

Thanks Mac and John, those are very helpful. The D72 specific one gave me
enough keywords that I could search the manual in a more useful fashion.
This radio does a ton of stuff.
No passes until tomorrow, so I have some for some more reading.

Patrick,
If, as you stated, SSTV has run its course, maybe Experimenter's
Wednesdays on AO-85 could be changed to experiment with EMCOMM using
NBEMS, thereby keeping AO-91 as free as possible.? Once that has
run its course, then move on to another experiment.? That would
keep things fresh.? I think a report on each experiment would be an
interesting series of articles in the AMSAT Journal.? I think
continuous experimentation is a good thing!

Mac,
Now that's a good idea. Otherwise, Wednesdays on AO-85
could be called SSTV Wednesdays, if that's the extent
of "Experimenter's Wednesdays" for that satellite. I would
be inclined to try NBEMS, something I've never used.

I've always been curious about NBEMS as well, Mac.
There is a fair amount of info on the subject online, but could you point me
to any particular orientation how-to that might be geared to someone using
it in a more informal setting such as how we might use it via an FM
satellite?

Scott,
I'm embarrassed to say that I've never done anything personally with
NBEMS.? What I
knowabout it isfrom a presentation at my radio club.? We have had a
group that was
experimenting with NBEMS on the club repeater.? Don't know whether they
are still
doing it, though.? They weren't using any special interface between
radios and
computers - speaker output to microphone input in both directions.? I'd
like to try
NBEMS on the FM birds simply as a way of experimenting with using LEO
birds for
emergency response.
As you mentioned, there is a lot of sites out there describing how to
use NBEMS using
Fldigi/Flmsg.? I have not seen anything specific, yet, regarding to
using NBEMS over
a satellite.? I'm sure that there are attendant challenges and
opportunities doing so.
Doppler shift and signal quality will be the main challenges. MT65
appears to be the
modulation scheme of choice.? Full duplex operation would be helpful, as
you could
monitor your own signal to verify its quality and how well the message
got through.
I'll have to investigate further.
73,
