Hi Kev,
The active FM birds are AO-51, SO-50, AO-27, and ISS. I think SO-67 and
HO-68 are sometimes available. I'm sure someone will correct me if I have
omitted any.
You can get their frequencies by clicking on each one on this page:
http://www.amsat.org/amsat-new/satellites/status.php
The doppler shift will vary throughout the pass, so there is no one position
that works. ISS has a VHF downlink that varies +/- 3Khz (approx) during the
pass. The others have UHF downlinks that vary +/- 15Khz (approx). It will
always be higher at the beginning, on frequency when the sat is at max
elevation, and lower at the end. Being FM, the tonal quality won't change,
the signal will just get weaker as it leaves the passband, so periodically
tune around for maximum signal strength.

Personally, I prefer to get folks in the habit of checking the actual

third=party Web site editing delays out of the equation.
I mean, what better info is there than that published by those who actually

I too am a beginner and wondered about how to calculate doppler and/or
determine a rough estimation based on pass information (elevation/az,
etc.). I tend to start about 10 kHz up on any given pass which seems
to be a reasonable approximation for most of the birds so far (I
started this way because I followed the AO-27 FAQ).
My biggest challenge is finding the signal while adjusting for
doppler. Once I get it though, I'm good for the rest of the pass!

But why do you need to reach a digi? You will be within wet-noodle range of
every APRS person at Dayton and they can hear/see you even if you are on low
power. There will hopefully be an IGate at the Hamvention to pick up
everyone.
Even if you run 50 watts, you aren?t going to get into a Dayton digi because
any digiepater that can hear the area will be 100% jammed on the input.
Limiting everyone to simplex or 1 hop only is the same technique used in the
Losangeles basin. Everyone that is there is there, and the channel is full,
so no reason to bring any more packets in or out.
See http://www.aprs.org/fixingLA.html
Ore more generically, everything there is to know about digipeating, and
MINIMIZING channel load.

Proper operation of an event like Dayton would suggest that putting up a
digipeater would be the worst thing to do. With over 300+ mobiles and
portables beaconing away all in simplex range of each other, a digipeater
would do nothing but drastically reduce the reliability of the channel by
half or more.
The proper way to handle a ham radio event with a massive influx of APRS
operations is to:
1) Have no digi at the focal point (Hamvention)
2) Have all digis going out 30 miles in all directions be ONE-HOP DIGIS
ONLY. That is, they only respond to WIDE1-1 or WIDE2-2 and nothing else.
They digipeat once and do callsign substitution so the packet goes no
further
3) Strategic IGates are placed right at Hamvention so they hear everything
in simplex range
4) Additional IGates are configured so that every surrounding digi going out
30 miles has an IGate to hear the one-hop packets.
5) Doing all the above, then the hundreds of APRS mobiles and portables do
not have to change anything. They just drive into town with their normal
WIDE1-1,WIDE2-1 settings.

Hi!
After I resubmitted my satellite VUCC application last Tuesday (10th)
through the Logbook of the World, things seem to be working so much
better. That application was approved the day after I submitted it
(Wednesday, 11 May). Then the VUCC certificate and pin were mailed
from ARRL on Thursday according to the postmark on the cardboard
mailing tube, and it was in my mailbox today. Now this is how the
electronic VUCC application process should work. Again, thanks to
those who have submitted their logs to the LOTW system. I'm now at
114 confirmed via LOTW, as one more grid was confirmed in the past
few days since my application was processed.
I'm happy that ARRL was able to process this application in a way
much more timely than my original VUCC application back in February.
I think there are still some bugs in the process of moving VUCC into
the LOTW system, and maybe some will be able to talk with the ARRL
folks at Dayton later this week about that. The document that John
K8YSE referenced earlier today about the discrepancy between VUCC
and DXCC application fees is an interesting read. It shows what I
(and others) have felt about the VUCC fee structure. This, too,
is something that should be brought up to the ARRL at Dayton. This
has already had an effect on whether hams will apply for - or get
endorsements for - VUCC awards.
For those going to Dayton, have a great time!
73!

I was originally wanting to get digipeated because I wanted to reach an
i-gate so that I could follow my track on the internet once I get back home,
and I didn't give it enough thought that a digipeater is not what I need -
it is the i-gate. A more accurate question would be, will there be an
i-gate at Dayton?, which it sounds like there will be. Other than that, I
do want the other APRS users to see me, but simplex will take card of that.
Thanks for your help!

Alexandar,
I am not sure how you have it programmed into the radio so far, but I would
program 5 memory frequencies into your HT:
(AO27)
436.805 (AOS)
436.800
436.795 (TCA - Time Of Closest Approach)
436.790
436.785 (LOS)
Since AO27 switches off way before LOS, you will probably never need the
last frequency - 436.785 - but these would be the common frequency steps for
a typical bird like AO51, SO50, etc. Don't be afraid to make adjustments
either. I find that to hear the 30 sec. of TLM right before AO27 switches
to VOX I have to be at 436.810. This is probably more a feature of the
radio itself. If you are having trouble hear at AOS or LOS, try adjusting
your downlink by 5kHz.
You can also add alpha-numeric tags to your frequencies to keep them in
order:
AO27-1
AO27-2
AO27-TCA
AO27-4
AO27-5
There are many different variations you can choose from.
73!

Hi Paul,
What satellites have you been listening for?
What are you using to determine when the passes are?
What are you using for antenna and radio?
The sats are there and functional - it has nothing to do with your location
as long as you have the pass times and locations correct.
There are a lot of variables that could account for your lack of "hearing".

What satellite(s) have you been monitoring, and what type of setup do you
have?

Hello,
I have been listening during satellite passes for weeks now, and hear
nothing. I am in DM03. Has anyone in the Southern California area heard or
worked a satellite in the past two or three weeks?

Paul,
I did 15 QSO's in the last 5 days from CM87 (San Francisco Bay Area) on
SO-50 (FM), VO-52 (SSB/CW) and AO-7 (SSB/CW). Are you sure you are looking
at UTC vs PST when predicting the passes? How old are your Keps? Just
checking :-)

Let me tell you what I have been doing:
I have programmed my TH-D72A with the TCA as a base. I switch to it
then move it to my VFO (F+VFO). When the bird is going to approach, I
instantly go up 10Khz and work from there. Its actually ridiculously
easy to just switch down via the tuning knob (so programming above
doesn't really buy you much). Typically depending on the bird's
doppler, I wound up finding the signal a bit lower than 10khz up (its
not like my AL-800 instantly picks up the signal at 5 degree
elevation) but when it does, I'm good for the remainder of the pass.
The AO-51 FAQ page spells it out very nicely. Knowing the polar chart
in your head for the pass is very helpful. It allows you to
gracefully move with the signal as the satellite passes over you.
My biggest issue right now is knowing when to call out. The flurry of
folks calling CQ on each pass where I live (FN20) makes it very hard
to either a) not step on anyone and b) even find a window to get in.
I will keep trying though (maybe when the weather gets a bit better on
the East Coast).
