Hi,
Yesterday I uploaded a short (2 minute) video on YouTube
featuring our fantastic new satellite Hope-1 (XW-1, HO-68).
It features the launch, satelite and its various modes
of operation.
If you listen carefully you may here these callsigns:
M3PQQ, N1AIA, KC9ELU, VA3FM, WA3CZY and I6IBE.
http://www.youtube.com/watch?v=o6oDgUTHCwg
Have fun !

Heard you on the 08:50 pass, Graham.
You were quite loud and clear at the beginning of the pass but
audio got progressively weaker as the elevation increased.
By about 40 degrees (at my location) the downlink signal was extremely
strong but I could not get in and no one else was heard, just a lot of
snap, crackle and popping noises.

Hi all.
Can anyone out there using HRD help me with this one?
The software tracks in very small increments which sounds really
impressive.
But can it deal with doppler tracking at higher frequencies?
For example, can it handle accurate tracking at S band from low Earth orbit
and could it extend that capability to 5.8 GHz?
Just trying to figure out the limits.

This morning I switched the satellite back to "normal" mode for a bit
with the 145.92/435.3 repeater on, set power levels on both 435.3 and
435.15 transmitters to 450mw and 500mw, and reenabled the SSB/FM
repeater. I believe the higher power on the SSB/FM repeater running
alone was causing some of the interference issues and odd behavior we
have been hearing and getting reports about. I did also briefly listen
to the 145.88 uplink in FM and there was non-amateur QRM there.
Let me know if this sounds more like the way this mode sounded last time
we ran it.
Twitter and the AMSAT AO-51 schedule page also updated.

I was hunting for OH-68 (XW-1)
And I came across some CW on 435.494 MHz
I can't seem to marry it up with another bird.
It did not have the "TTT" like XW-1 had.

I am struggling to keep control of NOVA and the sats I want to chase.
Some keps are missing, and there is alot of other general rubbish in the
list of sats.
What is the best way to create a list of "HAM SATS" I can manage ?

Hi Drew,
That is much better :-)
Worked like last time this mode was on.
Just had a pass with AOS at 1241 UTC here in Copenhagen.

Hi, I', relatively new to sats and I'm still a bit confused about one

It is regarding "uplink and downlink" mode configured for each satellite.
Ok for FM, SSB and so on.... But...
=> What about NORMAL or REVERSE doppler shift ??
=> When using SSB on transponder, what about when to use USB on uplink

I'm very confused if my doppler.sqf file is properly configured and a

Thank for your patience guys !

HI JEAN, VA2SS
I CANNOT UNDESTAND EXACTLY THE MEANING OF YOUR QUESTION
BUT SINCE THE TRANSPONDER IS MADE "INVERTING" THEN THE
TOTAL DOPPLER SHIFT BECOMES THE DIFFERENCE BETWEEN THE
UPLINK FREQUENCY AND DOWNLINK FREQUENCY AND IF THE
TRANSPONDER IS NOT INVERTING THE TOTAL DOPPLER SHIFT IS
THE SUM OF BOTH.
THE TRANSPONDER IS MADE INVERTING TO PARTIALLY COMPENSATE
AND REDUCE THE TOTAL DOPPLER SHIFT.
=> When using SSB on transponder, what about when to use USB on uplink
and LSB on downlink ??
SINCE THE TRASPONDER ARE NORMALLY MADE INVERTING IF YOUR
UPLINK IS USB THEN YOU RECEIVE A LSB DOWNLINK BUT THIS IS IN
CONTRAST WITH THE CONVENTIONAL TERRESTRIAL MODE OF
OPERATION THAT IS USB MODE
=> When using SSB on transponder, what about when to use LSB on uplink
and USB on downlink ??
SINCE THE TRANSPONDER IS INVERTING IF YOU TRANSMIT A LSB
UPLINK THEN YOUR DOWLINK WILL BE RECEIVED USB ACCORDING
TO THE CONVENTIONAL MODE OF OPERATION FOR TERRESTRIAL
COMMUNICATION THAT IS OK BECAUSE ANY OTHER AMATEUR STATION
CAN RECEIVE YOU WITHOUT TO SWITCH THE RECEIVER BETWEEN USB
TO LSB
I'm very confused if my doppler.sqf file is properly configured and a

I know this is a basic and fundamental question, but I really need to

Content-Type: text/plain; charset="us-ascii"
My first contact on satellite was 29-Dec-08 via AO-51 and the QSO was
appropriately with Clint Bradford, K6LCS. It is appropriate that it was
with Clint because Clint is the one that sparked my interest in working
satellites. I remember reading about amateur radio satellites in my
Technician exam preparation book where it was discussing the various forms
of amateur radio. I also distinctly remember the impression that the author
said working satellites was challenging and not easy to do. Along comes
Clint to do a demo at one of the PAPA System monthly breakfasts with his
Arrow II and an HT and showed just how easy it can be.
At that point I was intrigued enough to put an Arrow II on my Christmas wish
list and a few days after Christmas, I got myself on AO-51. I remember that
first pass seemed very busy but Clint and I had pre-arranged to work it and
having that successful contact fanned the fire. The next morning I got up
early and drove over to a local hill with no trees and buildings so that I
could work an early morning easterly pass of AO-51. I easily worked N9AMW,
K8YSE and K9QHO and I would say that it was that pass that firmly implanted
the satellite bug because that day I started designing an easy to use log
sheet to keep track of AOS, Max El, LOS, call signs, etc.
Trying to hold the antenna, a clipboard/pen and radio while tracking AO-51
in the sky, making QSOs and logging call signs, times and grid squares must
have looked pretty comical for the neighbors, but I never even noticed. I
added a clipboard lamp, a little digital clock and figured a way to mount
the antenna and radio on a tripod. This made things a lot easier but it was
still a chore to set up.plus now that I was not totally consumed in all I
had to do, I was noticing neighbors with raised eyebrows as I set-up in the
driveway.
>From that early start I graduated to a gable-mounted G-5500 with my Arrow II
and SatPC32.now I could operate from the comfort and privacy of my indoor
shack (and yes, there have been many early morning passes worked while in a
bathrobe). This past Thanksgiving I finally got a short rooftop tower with
high gain antennas and polarity switches. What a world of difference!
SO-50 is like a whole new satellite!
After year 1, I have 1500+ QSOs, 130+ unique grid squares and I'm still
hunting for my last five states. I've made several friends that I QSO with
regularly, sometimes multiple times in a day. I've enjoyed working the new
birds SO-67 and HO-68, unusual modes like AO-51 SSB/FM and I'm working to
get my S-Band set-up working and a couple of 70cm helix antennas built and
put into use (thanks to Mike/K9QHO for the info and encouragement).
Happy New Year to everyone and hope to work you on the birds sometime!

Works OK with a good preamp. I have one mounted on my Explorer with some
magnets from Harbor Freight, and an ARR preamp. Lots of guys here in
deed-restricted communes, err, communities use them because of their
stealth qualities.

I have both the RHCP and LHCP receiver versions, but with a house move, I
have not had the opportunity to test them.
