Hi all
I'm doing satellite demos for Field Day for my club, and I'm trying to
narrow down which ones to try. I'd like to demo two of each type, even if
all the audience is able to do it listen. So please let me know which FM
and which linear ones you would recommend.
For FM: SO-50, AO-27, and ISS (assuming that it will be on at all, either
in repeater mode or even better, a real live operator :-) )
For linear: VO-52, FO-29, and AO-7
I'm leaning towards AO-27 for listen only, as I know the bird will be jam
packed with ops that weekend (although I do have a decent pass at 230 am
local Sunday, and an even better one at 4 am) and actually trying to make a
contact on SO-50, although I'm sure it will be busy too.
Definitely AO-7 for my linear choice, as I know the linear birds won't be
as busy as the FM ones. FO-29 is my next choice.
I'm planning on using the Arrow antenna with my VX5-R for the FM birds, and
I have an M-Squared 2M/440 (same boom, but offset 90 degrees) with an
"armstrong" az/el control for the linear ones with my TS-2000X. (I'll also
have a longwire on the off chance that AO-7 pops up in Mode A, as I may be
working 20 M phone/CW when not busy with the sats.)
Any advice will be appreciated
Thanks!

Reservation in NC for FD)

Let me save you some sleep. AO-27 is only on for the ascending passes in the
afternoon, and only for 7 minutes starting at about 30 degrees latitude.
This means the first several minutes of the afternoon pass will be silent
from your QTH, and all of the overnight passes.

FO-29 and VO-52 will work better on FD, as AO-7 tends to get overloaded
easily.

Why give up full duplex and the TS-2000 to use the VX5 on FM? Half-duplex is
a poor choice for satellite on normal days, let alone Field Day. If it's
because of the birdie, use the TS2000 as the transmitter and the VX5 for
receive only.
Good luck. If you aren't a regular satellite user, try some passes outside
of Field Day to improve your chances of success.

Thanks, Drew. I didn't realize AO-27's status, and I wasn't really looking
forward to getting up in the middle of the night anyway :-) (although SO-50
has an excellent pass around 330 am :-) )
I did play around with AO-27 and SO-50 most of the day Wednesday, but yeah,
I haven't really been active on the sats since a 1993 AO-13 DXpedition to
VP2M.
The reason I'm planning on using the HT and Arrow is to show them the
(nearly) minimum equipment that can be used to work a sat - that they don't
have to have a fancy radio (IC 910, IC-9100, TS-2000) and a big antenna
array to work the birds. (I do have switchable CP yagis on 2M and 440 at
home, with an az/el rotor, but transporting all that would be too much
logistically AND I thought it would be overkill and too intimidating for an
audience whom you're trying to attract into ham radio.) But yeah, I'd much
rather have full-duplex like I did on AO-13.

Hi all & thanks Bernard,
If you follow up the report in view of the costs and other factors. One
of the options for an ATV future was for a use of recovery of debris and
satellites.
Whilst the cost may be considerably high for such a development, I thought
that it would be very interesting
and a positive step forward for study of failure and ageing factors of on
board equipment etc. (Batteries ??)
Also of course the objective of clearing up and reducing hazards of
possible impact or pollution.
Wonder on your thoughts on viewing this aspect as a effective application
of use of " Space Budgets"
Regards.

Hi Philip,
Happy to hear you are getting active again! Great.
One small precaution, based on personal experience during Field Day---be
careful about creating expectations that can't be delivered...in other
words, using the handheld system to listen to an FM bird is pretty easy, but
on Field Day, it might be impossible to get a signal into the bird for a
real contact.
When I've done demos on Field Day, I warn my observers that it's going to be
quite busy, and while we certainly will hear the bird, it's unlikely with 5
watts that I'll make a contact *today*. But letting them hear the busy bird
gets them interested, and has led to invitations to give a presentation/demo
at a local club meeting---which CAN more easily lead to making some contacts
(especially if you announce the event here on the BBS. People will look for
you specifically, in order to make your event successful).
If you're going to have both the TS-2000x and the little radio, you could
have somebody else waving it around to listen, while you operate the
transmitter. It's fun to have audience participation!
Not sure I'll be on the air on Field Day, due to work---but best wishes for
a great day.

Thanks, Mark. I've already made it clear to the other club members NOT to
expect a successful sat QSO.
I'm going to make sure that my audience knows that too. One hands-on
activity that I came up with (and I was already contemplating letting
someone else use the Arrow, maybe a repeat visitor who has already seen my
song and dance) - I have printed some copies of the grid-square map, and
I'm hoping the children especially mark their map during the passes as they
hear the grid-squares. I was astounded by how many grids I heard on just
ONE AO-27 pass on Wednesday!
There are very few hams in the area where we're doing FD, which is one
reason why we chose that location, to stir up interest.

Phillip,
You have already gotten really good advice from others on FD operation, but
I will offer one nugget from my experience: if you feel the pressure to
make that one satellite contact for the club, here is my recommendation for
the highest probability for success:
- pick an ascending pass of FO-29, preferably to your East (at AOS it will
be mostly over the Atlantic Ocean)
- pick a frequency at least 5 kHz above the center's downlink with Doppler
(at AOS this will be about 8 + 5 = 435.863 MHz)
- assuming you are not using PC-control, set your trasnmit 5 kHz below the
uplink center and call CQ
- be ready for the pile-up from the dozen 4-call stations in FL who will all
call you at the same time
You have about 60 seconds before the NE and mid-west get into the window...
after that, just play the downlink audio for the audience.
73 es GL,
Jerry, K5OE

We have been able to do it with a handheld for the last 5 years. But we may
have geography in our favor :-)
THE FOLLOWING COMMENT IS FOR NEXT YEAR!
Has anyone considering re-examining the FM satellite rule? I would like to
propose the following:
Contacts on the FM satellites can only be made with W1AW and K6KPH. Those
stations could get on with solid signals and pass out contacts. No other
contacts would count. I believe more contacts would be made, and it would
be better to listen to as well. We would have to get the word out early and
often.
Just My Thoughts,
Joe kk0sd

Thanks, Mark. I've already made it clear to the other club members NOT to
expect a successful sat QSO.
I'm going to make sure that my audience knows that too. One hands-on
activity that I came up with (and I was already contemplating letting
someone else use the Arrow, maybe a repeat visitor who has already seen my
song and dance) - I have printed some copies of the grid-square map, and
I'm hoping the children especially mark their map during the passes as they
hear the grid-squares. I was astounded by how many grids I heard on just
ONE AO-27 pass on Wednesday!
There are very few hams in the area where we're doing FD, which is one
reason why we chose that location, to stir up interest.

Wont work because there would be a 1000 ops calling 1 station,and field day
is about contacting many stations but on staellites only 1 contact is needed
for 300 points. Make the 1 contact and shut down your satellite station and
let the rest of us have our 1 contact and shut down also.
I hope the BIG GUN Satellite Stations will not use there amps to cut
through the pile ups. I thing the satellite stations should not use any
thing over 50 watts max on FM or better yet only use 5 watts and a hand
held. After all Field Day is about emergency comm. and not blasting everyone
out
Thats my thoughts . See everyone at the same time on the birds LOL
I will be operating W4BS in em55 for those that may still be trying to get
there 5 in em55 award

We have been able to do it with a handheld for the last 5 years. But we may
have geography in our favor :-)
THE FOLLOWING COMMENT IS FOR NEXT YEAR!
Has anyone considering re-examining the FM satellite rule? I would like to
propose the following:
Contacts on the FM satellites can only be made with W1AW and K6KPH. Those
stations could get on with solid signals and pass out contacts. No other
contacts would count. I believe more contacts would be made, and it would
be better to listen to as well. We would have to get the word out early and
often.
Just My Thoughts,
