To have an AMSAT rule that directly conflicts with the ARRL one-and-done
rule is ridiculous.

In the AMSAT rules we do state, because someone asked about it, you can be a
net control type station and work every station you want. You would only be
able to score one contact yourself but had given many out to those trying to
make the 100 point satellite bonus.
We still feel by limiting to one FM contact that if you worked someone and
both of you leave the bird, two more stations can work each other thereby
maximazing the number of possible contacts on the satellite during a single
pass.

One of the points made was that nowdays, working the FM birds is relatively
easy, and to give relief to? the crowded FM birds, we need more linear sat
ops.? ?How about giving 25 points for? the FM contact, but 100 for a linear
contact. You could do one or the other, not both.We are joking if we deny FD
isn't about points. You want the big points, you earn them. (Linear)You want
an easy 25, or do a demonstration, you get 25, (FM)?
It won't solve all the problems, but might relieve the FM birds somewhat,
and encourage linear operation.Bobwa7dxzSun City, AZ

I've suggested in the past we move the FM sats to either a net control
format (as others have suggested) or perhaps a bonus for copying a satellite
bonus message from w1aw or its relays... To emphasize receiving more than
transmitting.
Just my thoughts.

A couple of questions and observations sparked by your message. Note that I
have not yet participated in a Field Day, so I have no pony in this race.
> 1. Field Day is not a contest, it is an activity.
I think this statement right here is the crux of much of the disagreement.
While what you have stated is true in the grand spirit of the vision of
Field Day, the ARRL has also (as we all now) put out scoring rules for FD
QSOs and activities. So FD is *both* an outreach activity *and* a contest,
all at once. Most of the concerns raised only address one or the other.
> 2. In reference to point 1, logs are not scored or checked by the

> the people who only make one FM QSO per bird. The rule can?t work

I don't see it as being a set of behavioral rules, but of *scoring* rules,
and as such are enforced by peers. They work very well *for their intended
purpose* (which I agree is not to keep the satellites from getting jammed
up) and no other. In fact, as one of my colleagues in the IT world often
says, "There are seldom technological solutions to behavioral problems."
> 3. Making more than a single FM QSO per bird but not including them in
> your scoring does little to help with the mess on the FM birds during
Field Day.

If you're not scoring a second or third FM QSO, then technically, are you in
violation of the rule? Especially where there are good reasons to make those
additional QSOs, as previous posters have shared -- helping others make
their single scorable FM QSO, etc. -- which are in the spirit of FD as the
outreach activity. This is not to endorse camping on the sat from AOS to
LOS, of course, but I believe there is room here for *good operators and
operational procedure* to meet in the grey area between FD the contest and
FD the activity.

Neither rule prevents you from making more than one FM contact. Both
rules just prohibit you from SCORING more than one FM contact.

Hello Nico,
I am trying to use your script for GMAT and learn a little bit of it. I
am using GMAT R2018a 64bit for linux.
So far I have added a new "Ground Station" with the exact same
"options" of "New_York_City", but with the coordinates of Athens
(Lat:38.0246 , Lon:23.8442, Elev:0.230)
Also in the "Event Locators -> ContactLocator->Observers" I have
unchecked New_York_City and checked Athens.
I run the Analysis and get the following:
Target: LongJiang2
Observer: Athens

Apostolos,
I don't think you are doing anything wrong. Your results look correct.
But I cannot check everything because I am running the most recent
version of the script with the 29 June orbital elements.
Sometimes I also get the 'NaN' result in the elevation column. I think
this is a program bug. I found that sometimes it helps to do the
following: stop GMAT, start GMAT, load the script, immediately run
the script before doing anything else with the program.
I hope this helps.
73, Nico

To me this rule:
?7.3.7.1 Stations are limited to one (1) completed QSO on any single channel
FM satellite.?
Precludes stations from making more than one QSO on a FM bird.
I suppose that this is subject to interpretation, but to me that the intent
of the rule is to make the FM satellites available to more people by
rationing QSOes to one per bird. Making more than a single QSO and not
scoring them or not entering them into the log does not make the satellite
available to more operators and seems to fly in the face of the rule. I
understand why people do it, and under some circumstances it may be a good
idea, but to me it is against the rule.
Of course someone could ask the ARRL Contest Manager if this practice is OK,
but remember the old adage of not asking questions you don?t really want to
know the answer to. - Duffey KK6MC
