I notice that all the passes are scheduled during the local mornings,
and none of the passes are scheduled during local evenings. Is that
because the satellite is in eclipse in the evening?

Clive et al,
Just got the e-mail in time to hastily set up some equipmentfor the 19:30Z
75* max elevation pass for UO-11 over Hawaii.
706MKIIG, Arrow antenna on photo tripod, 25 ft. coax. So nothing special,
I was in a hurry not to miss the pass, orbit #38127.
The received signal was very weak, barely above noise level, but it was there.
Sorry, no recording.
Since my "long tom's" are still on the ground and pre-amps packed away in a
box,
I could not do any better. There are still a few issues to be
addressed,before my
old AO-10 class station is operational again. But then, no HEO in sight.
Would be
nice however to have the equipment back up, to take a listen.
The next two possible orbits (#138134 @ 24* and # 138135 @ 18*) are not
usable because UO-11 will be eclipsed on both passes.
Will do what I can to listen in future passes, work and honeydo's permitting.

Hi,
Very strong signals from UO-11 during the entire pass (2150 to 2202utc, 61
deg pass.) Up to 60db over S9 almost all pass. (TS-2000, 10 el yagis,
preamp at ant). Also same report from VK2AYE.
I have a recording of the pass.

Hi,
I have received two reports from Keith N4ZQ (EL88ob) that he has heard
UO-11 on 19 November at 13:33 - 13:43, and on 22 November at 13:02 UTC.
He has sent me a WAV file of the second pass. Unfortunately, it's a

I'll be interested in receiving any other reports. The frequency is

Not the switch unfortunately. The same problem occurs when controlled

Mike,
I had a slightly related problem which turned out to be the phase shift
capacitor in the rotator. You can see it on the schematic. The rotator
would work fine with no load, and would generate more torque than you could
stop with your hand. However, it would not move my array, which is
admittedly overloaded. There was definitely a thermal effect here, in that
on a cool day it would work a little, but not on a hot one. Replacing the
capacitor solved the problem, but it was messy. If they just plugged it in
but did not test it under a real load, they MIGHT have missed a problem. My
experience with Yaesu/Vertex techs is that they are either excellent, or
incompetent, with little in between.
If you can find a good capacitor, you can bridge the lines at the control
box end in parallel with the rotator unit. If it works, or works better,
that is a good indication of a bad internal capacitor.

Hi Mike,
If it works for a while and then quits, it kind of sounds like an over-temp
problem in the rotor (or perhaps it *thinks* it's over-temp'd). These
motors aren't designed for continuous duty. Maybe the switch is flaky, and
cutting out early?
How much weight do you have up there, and how's the balance?

Hi
Another very strong UO-11 pass here this evening. (0909 to 0922 utc, 60
deg) The signal became noisy with rapid fading just after UO-11 went into
eclipse at around 0919 but signals continued but gradually became weaker and
the fades deeper until I lost the signal in the noise about 1 minute before
LOS. I recorded the pass.

Hi,
I have received two reports from Keith N4ZQ (EL88ob) that he has heard
UO-11 on 19 November at 13:33 - 13:43, and on 22 November at 13:02 UTC.
He has sent me a WAV file of the second pass. Unfortunately, it's a
very low elevation pass, and probably will be difficult to decode, as it
contains a lot of noise. However it's definitely UO-11.
I'll be interested in receiving any other reports. The frequency is
145.826 MHz. Mode is FM. Further details are on my OLD website
www.users.zetnet.co.uk/clivew There is an audio clip to help identify
the satellite.

Hi Mike, KB8ZGL
Connect an AC voltmeter between A4 and A5 on rear of control box and
check if there is 24 volt AC when the rotator sticks.
If you have 24 volts when the rotator sticks connect an amperometer in
series with A4 or with A5 and check if the AC current flows as soon
the rotator sticks.
If the current flows when the rotator sticks probably the internal AC 100 uF
capacitor is defective or you have a mechanical problem inside the reduction
gear or into the ball bearing holder of your rotator
If you have a 100 uF AC capacitor in the junk box connect it across A4 and
A5 and try again to see the effect.
If you don't have an AC capacitor you can buit it by your self using two
electrolitic capacitors each 200 uF 250 volt DC and two diode 1N4007
or equivalent connected as per the following schematic diagram:
- + + -
|--------) |------|------| (--------|
A4-----| | |-------A5
|-------|>|------|------|<|--------|
1N4007 1N4007
If the rotator sticks and if the AC current don't flow you probably
have e limit switch SW6 or SW7 defective "poor contact and high
resistivity" between contacts.
Disconnect A4 and A5 from control box and using an ohm-meter
check the continuity of the motor windings
If one winding of the motor has a fail contact then your ohm-meter
will jump measuring the capacity of the AC capacitor.
This is what I would do easy and fast in your situation.
Have fun

Hello
Given that the SA-AMSAT payload on SO-67 is shared with the satellite back-up
TT&C transponder, there is unfortunately not a way to keep the payload
switched on permanently, or even semi-permanently. For the lifetime of the
satellite we will therefore have to do with active scheduling.
In an effort to make this as painless as possible, I would like to request
comments on the possible use of regional coordinators, which I believe worked
quite well for SO-35. Such coordinators would then be responsible for
setting up schedules in advance for their specific regions, taking into
account obviously the pool of possible satellite passes, as well as local
events / fairs etc. We would then simply load the schedules on a weekly
basis.
Up 'till now I have mainly focused on Europe, RSA, South America, North
America / Canada, Japan and Australia / NZ. I would like to invite
suggestions for use of the payload over other regions as well. This adds to
the previous point.
Regarding possible activation at night: this is entirely possible, but would
have to be planned / managed more actively, given the power limitations in
eclipse. We have yet to experiment with this and see what the available
capacity would be.
Please mail responses to this bulletin board, or if you prefer, to my work

I'm going to try and collect some telemetry here in FM29 next pass, at
14:50z. I still have my WinPack UO-11 config file, it is loaded up and my
DSP2232 is streaming 1200 baud ASCII, searching for a signal. Just like old
times! I will report back here, and send the telemetry file(if any) to
Clive...

Hi
Another very strong UO-11 pass here this evening. (0909 to 0922 utc, 60
deg) The signal became noisy with rapid fading just after UO-11 went into
eclipse at around 0919 but signals continued but gradually became weaker and
the fades deeper until I lost the signal in the noise about 1 minute before
LOS. I recorded the pass.

Hi,
I have received two reports from Keith N4ZQ (EL88ob) that he has heard
UO-11 on 19 November at 13:33 - 13:43, and on 22 November at 13:02 UTC.
He has sent me a WAV file of the second pass. Unfortunately, it's a
very low elevation pass, and probably will be difficult to decode, as it
contains a lot of noise. However it's definitely UO-11.
I'll be interested in receiving any other reports. The frequency is
145.826 MHz. Mode is FM. Further details are on my OLD website
www.users.zetnet.co.uk/clivew There is an audio clip to help identify
the satellite.
Please e-mail me via the AMSAT reflector, or post to this bulletin board.

Hi!
I'll add my "two cents worth." I heard the old familiar "buzz" loud and
clear on a Yaesu FT-530 HT and a hand held three element Yagi on the 1453 UTC
pass over Fort Worth, TX, this morning. It was certainly good to hear the
old familiar "buzz" and it reached full scale on the FT-530 during a good
part of the pass.

This was sent to our local ham club reflector. I thought it would be of
interest to a few satellite hams. Although it is a commercial site that
sells the ready made cables, the pinouts are all there for those that
want to build their own.
