You don't need GPS for finding folks at Dayton
Unless you are lost and cannot read a map.
I have prepared 3 maps of the Dayton Buildings and Flea Market
area that have LAT/LONG coordinates on them. Just manually
enter your coordinates for your space or booth or present
location into your D7 and then your radio will tell you which
direction and how far anyone else is...
Indoors, the maps work fine (GPS doesn't). Even at 60 foot
resolution, there are 75 discrete locations inside. In the flea
market, there ar 650 sets of coordinates to help you find
anyone. It also helps if you key in your space or booth number
into your text for the final few feet...
To find someone, enter your manual position into your D7, then
your radio will tell you which direction and how far away they
are! Or look at their coordinates on the these gridded maps:

John, the operation of FM voice satellites is a travesty for ham radio...
I've been licensed for 57 years, on amateur satellites for 33 years
(Oscar 7) and the FM voice operation is the most ridiculous
aberration I've witnessed in all of amateur radio...Pandemonium
exists here also!!
It is pretty obvious NO COMMUNICATION exists on AO51,
all of their communication is on here. Why do they bother to turn
the radio on???
Many of us attended AMSAT a lot conventions in an attempt to
discourage throwing that money "down the tubes" on FM voice, to no
avail. Someone had an "ax to grind", and several of the existing
"powers that be" in AMSAT-NA told me to "mind my own business". They
were obviously the "ax grinders".
FM voice on the amateur satellites is about equal to the same degree
of difficulty as a cell phone operation!
No wonder our membership is deteriorating.
Ancient AO7 and present VO52 hopefully are keeping some interest,
until Europe launches P3E....
That's where my donations go.....

I'm approaching 100 QSOs on FM sats and can average about 3-4 per pass.
I don't understand what the communication issues you are having. I
practice courteous communication and evangelize to others to do the same.

<rant>Yes. Let's toss our money on sats that only a select few people
with special equipment (e.g. stuff that a new Ham would not have access
to) that ought to show those plebian FM operators.</rant>
Your complaint is that the FM sats are in over-used and that SSB
satellites are less crowded. Such a statement points to the fact that
more money should be focused on FM sats rather the SSB as it would
"reach" the most people.

With the amount of people posting on here (and some lurking) that having
difficulty getting "on" AO-51, that statement is ludicrous.

Perhaps the solution is *MORE* FM sats, rather then less. The more FM
birds in orbit the less people per bird. Or perhaps the reason
membership is deteriorating are the attitudes give to us lowly FM operators.

Dave,
You have made it clear on this BBS before that FM sats are not your cup of
tea. I don't have any problem with that but I think your use of the word
"pandemonium" is a little strong. I would say that it's "hectic" but it's
possible to work stations in relative comfort if one knows how to pick and
choose their spots.
I'm right with you on wating for P3E, I missed out on AO-40 entirely. I
hope soon to be working AO-7 and VO-52 as soon as I straighten out an
antenna issue I'm having on 70cm transmit. I just think your attitude
towards the FM sats is wrong. They do have their place. Many people,
including myself got the thrill of hearing our signal beamed back to us for
the first time on an FM sat and we still enjoy it. C'mon now... a cellphone
call?? It's a bit more complex than that.
As far as membership deteriorating, I think narrow mindedness, about a
variety of things including FM sats, new frequencies and modes, cubesats
etc. etc. does more harm than anything. Of course I've only been licensed
for 30 years so I guess my opinion doesn't count hunh? ;-)
73,
Michael, W4HIJ

And now for a dissenting opinion.....
FM sats work. They serve a good purpose. I, and a hundreds of other sat ops
enjoy them. Sometimes the communications can be chaos, but most passes here
they are not over used.
Dave are you one of the guys who also complained about the 'ditters' on the
linear birds? And the guys who don't follow the 'one true rule' on the
linear birds? And the guys who slide by up/down onto your qso on the linear
birds? And the guys running too much power and loading down the passband on
the linear birds. Is that good operating?
Yes, poor operating habits can appear anywhere. So instead of grinding your
ax all the time, be an elmer.

Im tired of the old FM bashers.
The FM birds attract a lot of users and QRM.
So cleary a lot of folks like them.
Besides, tune into any of hundreds of frequencies on the ham
bands during a contest and you will hear the same thing. Zero
usefull commmunications capability but a heck of a lot of folks
seem to be enjoying it.
I wish the old fud FM bashers would just go find something in
Ham radio they enjoy and go do it, rather than complaining about
what others find fun in the hobby..
My experience in 46 years of ham radio is that there is room in
it for everyone and everyone's interests. But nothing,
absolutely nothing, is gained by bashing what other people
enjoy. If you find something you like in the hobby, do it. If
not, then get out of the way.

I have gotten good reception using a signal generator with -20dBm
output on 800-MHz to a simple diode paralleled by a 47-ohm resistor
mounted in a coffee can placed 20-feet from my dish (my receive
system is very close to Franscesco's in performance). I used about
40-foot of RG-58 for the 800-MHz signal so that dropped the signal
another 13-dB or so. The third harmonic would be less than 1/3 the
power of the 800-MHz signal.

Dave,
It is obvious that there is a whole generation of Leo-FM sat users
that are clueless of what ham radio on a Heo linear-tranponder is
like. Although it must be harder than a cell phone since so many
cannot seem to figure out how to operate on the Leos...I would say it
is not "much" harder than using the local repeater.
I offer an analogy: Compare all the ham radio contacts that are done
on HF with the same number of folks trying to talk thru a single FM
repeater! First it cannot be done; second the attempt results in
total chaos with "big fish" eating the little fishes!
I am waiting for the next Heo and hoping it survives better than the last one.

Tnx, Ed....
I've received dozens of responses similar to yours...
I just hope AMASAT-NA is not "down the tubes" as is AO-51

Oh, no, Michael,
I spent 28 years, in three wars, as a navy fighter pilot to make sure
they do!!!!

Is there any possibility that one of the major manufacturers will
introduce a new satellite rig in Dayton? Or that the mail order
houses will have special prices for those who can't attend Dayton? Is
that a common practice?
I'd like to thank everyone on here who replied when I mentioned that I
was starting back up on satellites. Your suggestions have pretty much
convinced me that I should go with the Kenwood TS-2000. So if anyone
strongly thinks that I shouldn't, please express your thoughts on this.
