Hi All,
At 19:40UTC today I tried the mode LU pass on AO-51 over europe. At first I
couldn't hear my SSB
uplink signal on the downlink so I switched to CW. That worked. I noticed that
the audio level on
the downlink was very low. My 23cm signal level at the satellite must be good
because mode LS is
working OK.
Heard my CW signal on the downlink from 4 degrees el AOS to 3 degrees el at
LOS. Hrd also one
other station trying with CW dits/dots and heavy 23cm radar signals.
Station:
Uplink: IC-910 10W and 26el yagi
Downlink: IC-910 2x16el Yagi

Due partly to the very low modulation level it took me four passes to
get my uplink frequency correct into SatPC32.
On the 21:24 low Eastern pass I talked to myself.
On the the 22:58 pass just completed Drew turned up the deviation
but it is now overkill and on my signal dissplay it covered about
30KHz. Turned my mike gain away down and was able to work
VE2DWE. Several other stations were on but could not make
out any calls.
Birds and situations like this make satellite operation interesting
and challanging.

Actually Gould did it, I was just the test signal, and a poor one at that.
We will continue to tweak it over the course of the evening until we get it
right...it is way too hot right now.

So ... I had just finished working Rick, WA4NVM, on AO-16 in "bent pipe" mode
at 23:03 UTC when I heard Mike, WB9L. I chased the Doppler a bit and had
called him a couple times when he finally answered and we made the contact at
23:04:39 UTC. AO-16 was at 4.1 degrees elevation for me, and my signal
(according to Orbitron) travelled 2,885.516 km to the satellite - 5 watts from
a Yaesu VX-7R HT going into an omnidirectional eFactor dual-band antenna. I
was excited because Mike lives in Indiana, my 7th state worked on AO-16. Then
I got an email from Mike, and from Dave, KB1PVH, in Massachusetts, and I
realized what happened. As AO-16 was between 4 and 4.5 degrees elevation far
to the west of me (269 degrees azimuth), AO-51 was at roughly 19.5 degrees to
my northeast (45 degrees azimuth) using the same FM uplink as AO-16, on
145.920. So WB9L and I made a cross-band, cross-mode, cross-satellite contact!
I'm sure it's not a first, but it's a first for me - and just about the coole!
st QSO-in-orbit I've had to date.

This last pass of AO51 I could hear Luc very well. I'm having an uplink

Hi
Something happen at 2300Z (1900EST) suddenly the audio level jump louder by a
factor of 4 i have to reduce my volume level and i found my
TX audio was also much too loud... Now AO-51 look like AO-16 audio and QSO are
manageable. I succeed to have one with Clare VE2NPC and i
also copy a lot of station but at the same floor level strength i used to have
before my adjustment (see below).
Only Clare VE3NPC signal seems to get over this curious bottom floor level??
To be clearer all the station coming out the satellite are equal in strength?
Only Clare was louder as a kind of AGC treshold seems to be
set too high making a kind of squelching effect?
I just made some adjustment here at the end of the afternoon in a hurry and
from an uplink signal very marginal it became near Q5!!! i'm
not too sure what i done and if it is what i done who boost my uplink but i
will have to make some test again as said something happen also
on the satellite at the same time?
More to come...and i was able to hear my downlink at LOS + 3'!!!

The command team was experimenting with improving the signal on the L/U
transmitter during the passes this evening.
The greatest improvement was noted by taking the resistor out of the path to
the transmitter, then lowering the amplitude of the signal to keep it from
clipping.
The U downlink now shows that a number of stations are trying to access this
mode. Some are even trying FM uplink :-(
We will be switching to the FM uplink on the late east coast pass tomorrow
night.
If you have 1.2 GHz SSB equipment give AO-51 a try.

Thanks to WA6FWF for talking me through a qso on ao51. Not using computer
control is a very touchy effort with the doppler up on 1.2Ghz. At least now I
sort of got the hang of it.

Hi Bob
You don't need any tone on the 1.2GHZ uplink. I adjust the doppler here
manually this way i can adjust the audio pitch and he's also quite
fast that's why many stations are always aside and they are searching for
their downlink in the QRM. I found also that i got an issue on my
5/8" Heliax line i have a 45' run but i discover an anormal attenuation
losses. I made some change in a hurry this afternoon and first
results seems to confirm 2 possibility a faulty coax or connector jumper at
the station or at the antenna or the SO-259 Heliax termination
at one end induce a too great mismatch?
It takes nothing to ruin the signal at 1.2GHZ!

Wow! This was the first time I worked AO-16. Of course I was the only
one on AO-16 at this early hour.
Since I don't have any antennas up for satellites at my house (yet) I
worked the satellite from my truck. I hooked up my arrow antenna to my
FT-857 for receive and used a 5/8 wave vertical on my portable for the
uplink. I couldn't believe how clear my 5-watt signal was making it to
(and from) the bird! On that little antenna and my HT I was full
quieting into AO-16!
I can't wait until the next pass!

On the morning pass i was able to have a QSO with WO3T Carm and VE3NPC Clare
signal where good but manually adjusting the doppler became
more and and easy with the usage. I guess some adjustment where made live as
the audio deviation swing and i think too much make only the
noise appears too high and it distorded the audio too much. The best setting
is where the noise start to increased a bit.
I was able also to determine my transverter IF in zero beating my carrier and
checking the frequency on a scope display. 1268.692,100 MHZ
equal to 144.01355MHZ on the exciter now i will have to figure out how to
enter theses values in the tracking programs.
I was able also to confirm my last minute quick station modifications make's a
huge difference on the uplink. My previous configuration was
the FT-847 driving the 1.2GHZ transverter who delivers about 3 watts into a
downeast microwave 18 watts amp. The TX line was a 45 foot 5/8"
heliax feeding a 25 elements loop yagi. In this configuration my results where
less than marginal.
Just before the evening pass i take the amplifier from the shack and i
literally planted it over the heliax male connector at the antenna.
i wrap the amp and the 12V DC line in a clear plastic bag to be able to see if
any moisture build up inside, as the amp heat sink became
quite hot.
Bingo my uplink is now quite good "lesson learn" put your amp at the antenna
not in the shack... I don't figure out why there was so much
attenuation in the heliax? or it is a lossy coax jumper l used RG-214/U at
both end only at the shack i have a SO-250 plug at the end of
the heliax where i should used an UHF to BNC adaptor??? Any ideas!
Finally this SSB L band experience was a good one and with the satellite
deviation tweaking (Thank's to the control teams) this mode is
quite effective even if it still not a killer one.

AO-16 is a very strong bird; it's one of my favorties. There is some
distortion on the downlink, being that it's FM up and sideband down,
which makes for some interesting RIT work, but I enjoy it very much.
Sad to see that it will probably be going away soon for just awhile we
hope.

I found myself wondering about the distances involved in the cross-band,
cross-mode, cross-satellite contact between WB9L and N3TL yesterday, so I did
a little research, then some math. Here's how the contact worked, based on the
distances at the time when WB9L acknowledged my call to him and we completed
the contact:
My FM signal travelled 1,808.086 km (1,123.493 miles) northeast to AO-51,
which re-transmitted it in FM 1,684.521 km (1,046.713 miles) west-southwest to
him.
His FM signal travelled 2,576.642 km (1,601.051 miles) west-southwest to AO-
16, which re-transmitted it in DSB 2,885.516 km (1,792.997 miles) east-
southeast to me.
Ain't that a hoot?!

Are you ready for SSTV yet?
If the SSTV project is activated from ISS, we may only see a few hours of
activation during the 10 day mission.
In last memo, I omitted the link page where I keep some of my SSTV software
links.
Thanks to a reminder from WB2LLP Gene Marks, I have updated the software
page links. This page should give you find a few SSTV applications and
helpful links that are available.
Question:
Is SSTV on VHF different from SSTV on HF?
No, SSTV is the same on HF and VHF. When someone says they are sending
"Robot-36" it?s the same format for all bands. HF usually runs SSB and VHF
usually run FM. Most voice flavors will work for sending SSTV. There are
also a few flavors of Digital SSTV; however that?s beyond our scope at this
time. ISS will be using Analog SSTV in Robot-36 Mode.

The standard downlink of 145.800 will be used for voice contacts, school
contacts and SSTV transmissions. Anyone with a FM receiver capable of
monitoring the 145.800 MHz downlink can receive audio and SSTV images. The
standard voice uplink frequencies of 145.200 for ITU Region 1 (Europe, Africa
and Russia) and 144.490 for ITU regions 2 & 3 (N. America, S. America,
Southern Asia, Australia) will be used.
