"Seeing how well I did on the ISS and NO-84, it is unfortunate AMSAT limits
the use of the orbiting digipeaters to a single QSO per satellite under its
Field Day rules. I don't disagree with the "one QSO per FM satellite" rule,
but question its application to the orbiting digipeaters. It seems like if
we are wanting to encourage more than just FM satellite operation during
Field Day, working packet would be one way to do that. Especially with that
NO-84 pass where only two of us were around to make QSOs."
My research from the AMSAT-BB archives shows that the one QSO per FM
satellite rule was added for 2001 after the chaos that ensued during
Field Day 2000. The rule was also applied to all single channel
satellites, including APRS digipeaters. In recent years, the use of
the ISS digipeater in particular has fallen off a cliff. Reading
through the AMSAT-BB archives I see reports of operators achieving the
AMSAT OSCAR Sexagesimal Award and VUCC solely through the ISS
digipeater. With the level of activity today, that seems unthinkable.
It may be time to suspend that rule for next year and evaluate the
effects.
My biggest rule wish would be for both the ARRL and AMSAT to limit the
ERP allowed on satellites. I listened to one pass of AO-73 out over
the Atlantic early Saturday evening where one station was tuning their
tube amp during the pass (I could hear their tone shift from extremely
harsh to pure). They then proceeded to CQ on CW and phone for the
entirety of the pass, without even a few seconds of a break. I was
never able to hear my downlink on that pass and only heard one
successful QSO.

here is a link to UO-11 from the past. yes, the rules do allow for the
use of this type of satellite should one ever be launched again with
this type of capability. it is basically like sending and receiving an
email. you send a message up, satellite orbits and somewhere others
download the message. then they might send a message up and others
download that one. the point was for field day for you to send a message
up and get points. then when you download other peoples messages, you
get points. not to send yours and receive your own for double points.

Then what I am hearing, "AS A NEWBIE" is that I am not welcome on the Sats
because I do not have the financial resources to invest in all the equipment
needed to run full duplex. It is more than two cheap Chinese radios, it
also involves an antenna, which at the very least it is almost double the
cost of the two Chinese radios.
Money that some of us have a hard time pulling together.
I have a hard time with all the purest, my way or the highway mentality I am
hearing.
Just my 2 cents

I could care less whether you have ever uttered it or not in one of your
live presentations. It is printed in black and white in your handout.
You just quoted it yourself. The minute you typed that phrase and began
giving out handouts or telling people to print it out you became guilty
of spreading ignorance as far as satellite operation is concerned. You
are leading newbie sat operators down a path they should not be on. If
one does not have the means to hear their own signal coming back from
the bird so as to insure they are "making it there" then they should not
be on the satellites. End of story.

Hi,
As previously announced I'll be in HM59/69 grid line operating FM
satellites from June 29th to July 1st.
Predicted passes are from evening June 29th (not morning as
announced), June 30th all day and July 1st morning.
You may follow me on Twitter for updates and last minute changes.

The financial argument is a weak one at best. A WA5VJB Cheap yagi is about
10 dollars of materials (you can skip the diplexer with two radios), and I
have recently seen and purchased older full sized 2m HTs and UHF analog only
scanners for as cheap as 5 dollars at hamfests. Add a $30 Baofeng and you
have a satellite setup for next to nothing.
Don't want to build or can't? The price difference between an Arrow antenna
with a diplexer, and one without is about $60, or the cost of TWO cheap HTs.
Use the extra $30 to buy some good cables.
I certainly don't mind if those getting started try half-duplex at first,
and it has it's place in some situations. I even wrote an article 10 years
ago about half duplex ops with the FT-817 on FO-29, which I plan to update
soon, but the linear sats are different animals, with different challenges.
Once you try full duplex and realize the benefits of being able to hear if
you are causing or being QRM, and being able to twist the antenna during
transmit to get a better uplink signal, you won't want to go back to the old
way.
