Which is why it is not a good idea to use V/U because it
demonstrates a totally saturated and unuseable satellite
channel. Uplink congestion on VHF where the link budget is 20
dB stronger than the downlink is the limiting factor and it is
total bedlam/gridlock on FD and is a poor demonstration to the
rest of the community and to other observers.
The L/U would be the best demo, because the uplink contention
will be much less, yet EVERY field-day site can demo the
downlink. The FD demo should not set themselves up such that a
successful 2-way is required for success. Such stations will
fail. It won't happen, or if it does, it happens by stomping all
over others. This is not a good dsmonstration for ham radio at
FD.
Better to plan on success as demonstrated by good downlink
reception. THen everyone is successful. And the downlink is
nice and clean just as we all dream of.

It's been my perception that a good portion of AMSAT's sustaining
members leave and breathe the highest tech they can manage. Eight out of
eight satellites being V/U seems counter to that goal.
Mark and Bob both make good points supporting at least one area of
refuge for this portion of the AMSAT population. Personally, I think the
V/U FM experience on Field Day is a big turnoff to newbies, especially
since so many under-prepared, over-powered and out of practice
once-a-year sat ops fail miserably to get those bonus points on FM.
I bet someone in your area has 1.2 Ghz capability!

Hi Drew, thanks very much for your feedback! Guess I was too na?ve earlier,
but now see the light! :) Also after reading threads from Robert and Mark,
I agree, there might be too much non-productive traffic and high
expectations, especially on FD. I will stick to receive only as Mark
suggested! My vote is changing to L/U ....just in case I can't find a 1.2
GHz receiver :) ...learning a lot from you guys and this list, thanks!

Wondering why all the hoopla about any of the satellites being in any
mode. AMSAT receives only about 15 entries for field day. The rest
must be doing only demos or making the one bonus contact. With
hundreds of field day stations on the air we should have way more
entries.

This evening I enabled the power management software on AO-51. If
everything works right, the repeater should run at 1.01 watt while in
sun, and 290 milliwatt while in eclipse and after exiting eclipse until
the batteries recover to ~7.9 volts. Observations from the southern
hemisphere while entering and leaving eclipse would be very helpful...we
know it is getting used from the WOD files. I'll post a map where the
satellite is being used soon.

Quick and dirty, but it gets the point across I hope. The red roughly
represents the areas where the AO-51 V/U repeater was being used. Over
24 hours the on time is averaging ~45%.

The few entries you get are from folks like my club K4CQ. The club is
not interested in the Amsat Field Day. They allow me space on the
tower to mount the antennas because it gets them the ARRL bonus
points. I do it with hopes of influencing someone to become interested
in Amsat. Has not happened as yet. I wont be in town this year for the
operation so it wont get done. Guess you will have one less score to
add in this year. I will miss the fun.

OK, Bob, I am convinced that L/U might be a better display of Amateur Radio
Satellites for the newcomer on Field Day. The sticking point remains there
are many prospects who will not get the chance to listen to these bands.
That is is unfortunate! Experience solidifies that Field Day is a poor time
to demonstrate an FM satellite, so I am going to save a day other than Field
Day to positively demo an FM bird. Any FM satellite will sound the same with
the same number of participants. If you limit the playing field you simply
reduce the number of players. I think this is how we get the an elitist
label, but I will bite the bullet and demo L/U on Field Day if that is what
is playing (a bigger radio and more gear unless I can get a converter to
work with my D7A HT. Do you want to put a MIC-E position burst on the end of
your transmisison? It may make an interesting Roger Beep... Can you count
that as a 2-in-one contact (voice and digital?) to keep things interesting.
Of course using 9600 baud for the MIC-E who would even notice the signal?
Maybe a little innovation here?

Jacob,
They will work, but understand that you will be dealing with a VERY
WEAK signal. In my opinion, not the best for a starter antenna. An
experienced operator who knows what they are getting into, and is
willing (or desiring) the extra challenge can do fine with them. I have
used a set of those loops for mobile operations, but I also have
thousands of satellite QSOs in my log, and I know what I can and cannot
do with them.

Hi Gordon,
Ok, that makes two of us with the same guess. If so, then it only affects
the Receive side of the rig, so for turning on the Transmit side 67hz tone
for getting into AO-51, it shouldn't matter which one I use. Easier to
program if I can just use the first one I find in the table...
Thanks,
Greg KO6TH

Personally I just use my Arrow II hand held yagi and my Yaesu VX-7R for
working satellites. Its a little challenging doing this without a tripod,
but if it was easy it wouldn't be as fun.

Ron,
I really like your message, "if it was easy it wouldn't be as fun". All to
often some satellite operators build taller and bigger having unrealistic
expectations and stop smiling after a pass. I've been helping a club member
who has been a ham over 40 years, he was timid about what it took to make a
satellite contact. I put an Arrow in his hands, taught him about frequency
steps for Doppler, and how to use his wrist during a pass. A week later,
John how did go, well haven't had the chance excuse. John, look I will pick
a pass for you 40 degrees, just listen, he did and the smile started. The
next day, he had three confirmed QSO's, would of had more but his pencil
broke in the excitement, digital tape next, his smile is not going away!
keeping it simple and remembering "if it was too easy it wouldn't be as
much fun, thank you Ron.

Peter,
>From past studies, mode L/U is the place to be if you want to work someone
on AO-51 without an EME station. ;) While the V/U FM repeater was choked
on every pass, there were very few stations on L/U. In the four passes I
monitored last year, totaling 46 minutes, there were only 21 station heard.
Half of those were on the first pass, and by the last pass on Sunday, only
one plaintive station calling.

Thinking along those lines
Speaking for a "Non" satellite station point of view. I saw on here (I
think) that the power level was going to be slightly higher for the current
schedule. I have an FT-847 and a 6m/2m/70cms omni on the roof. I also have
a 2m/70cms pre-amp near the antenna. On a pass yesterday morning, I could
hear AO-51 reasonably well (when folks weren't keying over one another) so I
dropped my call-sign into a small gap. 4 contacts later (and one on the
next pass), I'm still smiling.
Looking for a cheap rotator now suitable to hold a small beam for VHF/UHF.
Actually I have a Mini-kits L-band LNA. Any pointers for a simple to
construct antenna?
Regards
de John

Greetings from pat n2oeq
Way to go andrew and all others involved in formulating and using the Echo
power management software. A very significant improvement to utilize
the available solar power.
Please keep in mind, the possibility of more watts while in sushine if power
management allows. I'm loosing lots of signal in the trees. I
learned like others said, that the leaves really attenuate the weak signal.
My sincerest thanks to all that made this big improvement possible.
pat
