Curt, I think I heard you in there, but there might have been too many
stations on there for me to call you.
The reason we talk fast is because of what someone already mentioned,
AO-51 goes by pretty quickly. It's a very popular satellite, and the
typical QSO is like a DX QSO on HF; with the exception that we
exchange the grid, for those working towards VUCC.
Many of the AO-51 users realize that if they talk for a long time,
that only cuts down the number of stations that can use the satellite
during that pass.
Now if you want to be able to talk a little longer, I suggest you use
SO-50, which is underutilized in my opinion. SO-50 requires a PL tone
of 67.0, otherwise no one will hear you. I suppose that might be one
reason why it is underutilized. A lot of hams may not realize that,
and can't figure out why they can't hear themselves on the bird, and
they give up. If you are able to work AO-51, you can work SO-50, so
long as your radio can do PL.
I don't know the history of SO-50, but my guess is that it was decided
to use a PL tone, because of QRM from non-licensed hams using high
powered 'cordless phones' sold in some countries, and perhaps some
illegal users on 2 meters in other parts of the world. Once you've
been on AO-51 for a few days, you will realize what I'm saying!
Now if you really want to chew the rag, then you need to get on one of
the SSB birds, such as FO-29 or VO-52; that is, if you have the proper
equipment. There you will find that a pass can last a lot longer than
AO-51, and not be limited to one 'channel'. But unfortunately as
well, you will find those to be much more severely underutilized.

I worked KU8L and I don't know if I was his first satellite QSO but glad to
welcome him. See his post on being new to the birds. . . . he indicated we
talk FAST . . . well Sebastian, W4AS covered why we do . . . nice comment
Sebastian . . . . it is very nice to see newcomers post with comments . . . we
need more of that . . . . we also need to lead by example by using intelligent
operating procedures . . . AO51 is a great satellite . . . as Sebastian has
pointed out , you can rag chew for 10 minutes on AO 7, VO 52 or FO 29 on SSB
. . . AO 16 although not with us much longer, also has some "group
discussions" on it . . . .
Keep up the good work . . . . when an expedition to a Grid Square is in
operation PLEASE defer to that station who has put in a lot of time, effort
and probably expense to give folks a new one . . . the operator of that new
GRID should probably try to announce in some manner that he is operating a
Grid Expedition so some who might not know will get the message .

Been trying to work on the 9k6 digital side using Wisp
Have had no data from AO-51.
Can anyone help to get me to be able to use the sat
Was able to work GO-32
thanks Pete

Yes...Jim you were my first...(whens the last time you heard THAT? :) )
I understand the need to keep QSO conversation short--similar to contest
work.
I think the skill for listening and processing phonetic calls and info
is the same as I learned as an instrumnent rating in-training pilot.
Its all new to the ear so we must get in the habit of decoding the
information. Next time I'll have my recorder running so I dont have to
write everything down.
Thanks Jim, Sebastion, and all...I'm going to try out SO-50 this
afternoon. And will try AO51 again after that.

KU8L - if you were trying to work that 0050 UTC (1950 EST) pass last
night, I did not hear you on my recording. I hope to hear you on in the
near future, so I can put your callsign in my log - from wherever I happen
to be operating from. Welcome to this corner of our hobby!
I, like many, sometimes talk a little faster to complete QSOs. Especially
when the contact might be for a new location, so others can make a
contact with that station. Also, if the contact is with a station that I
have worked many times in the past. If I work someone who has any
difficulty with my call, I will s-l-o-w down a lot when spelling out my call
phonetically. Sometimes it may sound painfully slow, but it helps with
the ultimate goal of completing that contact.
Listen to passes, try to make some contacts, and run a recorder and
listen to the passes again at a later time. Then you will get acquainted
with the operating techniques, different stations, and how all of this
happens in the span of 10 to 15 minutes.

Speaking as one who has made several trips this year and put different
grids on the air, this would be the ideal scenario. This would be similar
to a DXpedition or a big-time contest station on HF that has a frequency
all to themselves. With single-channel satellites, this is not a realistic
wish. The best I can hope for is for passes that are orderly. Those
wanting a QSO with the station in the rare/unusual grid(s) gets the
chance for that, and someone wanting to work another station on the
pass can do that as well. For a new satellite operator, a contact with
*any* station could be a new one for them.
If I didn't accept this reality about the single-channel satellites, I could
confine my grid expeditions to the non-FM satellites like VO-52 and
FO-29. Then I could pick a spot in the transponder and stay there,
allowing those who wanted a contact with the grid(s) I happened to
be in could do that. Anyone else could just tune past me and go to
another point on the transponder. This also dramatically limits the
potential number of contacts I could make on a pass, since there are
many more operators that have the gear for FM satellites compared
to the non-FM birds.
