No the signal from the balloon is plain old CW.

Greeting fellow operators,
Thanks to the many operators I have worked over the past few days under
horrible weather and operating conditions.? We have had nothing but
torrential rains and high winds in Hilo for the past few days. We even had a
4.9 Mag. earthquake North of us 24 hours ago which we felt locally.
I am posting to the general group my last passes for today in case someone
wants to try to work me who was not on my request list.? Please note I am
having trouble with AO-7 down-link, it is very weak here so please don't
assume it will be easy to work me on that satellite. Also do not CQ for me,
I will be CQ'ing as the DX station. USE LOW POWER ON AO-7!!?? Be patient and
await your turn assuming I can hear you. Better bet are the two FO-29 passes
I plan to be on today.??

Monday we are heading to Kailua-Kona. I still need to do a sight survey to
see what is possible since there are two volcanoes in the way.
I will also operate more ad-hoc since I would be operating in the field and
all operations from BK29ao are dependent on the weather. I will mostly
likely operate closer towards the middle of the week if possible.
I will be heading up to BK19 on one day to do a sight survey to get a feel
to see if this grid is even possible to operate from. Maybe with some high
angle passes. I will advise.
I am also looking at the JA opportunities for this coming week. It may mean
an early (02:00AM local time pass) I will advise.
Aloha Adrian AA5UK/KH6

The CubeSat section of this show was in the final 8 minutes and featured
both the Vandenberg Air Force Base and the Surrey Space Center with an
interview with Peter Shaw of the amateur radio STRaND smartphone satellite
project.
The other 51 minutes are also well worth watching.

Folks,
I noticed during the earlier pass
today I could not hit SO50 and now during the FO29 @ 2240Z pass I could
hear lots of people but not transmit into the satellite. I pulled
everything apart and ran checks. As far as I can tell some RF must have
gotten into my IC-7000 and locked it up. I did some testing and I have
SSB working again. Hopefully this was just a temporary glitch.
I will know more once try on an upcoming pass. Keep your fingers crossed.
Sorry for those who were trying to work me but could not find me.
Aloha Adrian AA5UK/KH6

Aloha friends,
It came down to a locked IC-7000 and a bad PL259 to BNC adapter. Luckily I
had a couple of spare ones with me. Radio Shack is not around the corner here.
I just did a check on the 0026Z FO-29 Pass and all was in order. We are back

Content-Type: text/plain; charset="iso-8859-1"
I am refurbishing an old KLM 435-18C that has a KLM CS-2 polarization
switcher on it.
I need help in understanding the design of the 37 ohm impedance strip line
transformer that is inside the CS-2. By my calculations the transformer
line length is half as long as it should be (1/8 wavelength and not 1/4
wavelength). However, it is folded, and I suspect the answer is in the
folding.
If anyone on the board is familiar with strip line design and would be
willing to trade a few emails (outside the reflector) on the subject I would
really appreciate it. I have been unable to track down what I need after
many Google and Bing searches, so appeal to a much better source - this group.

Message-ID: <537172.62239.qm@xxxxxxx.xxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
Every now and then someone asks about the possibility
of making a satellite QSO when the bird is below the
horizon. Once in while it happens as it did with Adrian,
AA5UK/KH6, on FO-29 this morning at 0849utc.
Adrian has been operating from KH6 and trying to give out
WAS to the deserving. Many have made their first Hawaii
QSO thanks to his efforts. I had a 0.8 degree pass this
morning on FO-29 but when Adrian was at 3 degrees, I was
at 0.0 degrees. There was a short window of opportunity
after that point.
As I was waiting for FO-29 to come up over the horizon I started
hearing Adrian at -0.9 degrees. At -0.5 I called him and we had
a qso that ended about 2 seconds after my AOS. My recorder is
configured to start recording at AOS and it only captured a few
seconds of my last transmission. Doug KD8CAO had his recorder
running so you can hear my qso that took place below the horizon.
I have my ground elevation in the setup so the calculations should be
accurate.
The best opportunity for a below the horizon contact occurs when
the satellite is skimming the horizon rather than going away from
you. If it is skimming there is much more time at the critical
-1.5 to 0.0 degree elevation and that is what happened this morning.
Recordings are on my website. http://www.papays.com/sat/general.html
A big thank you to Adrian for making the effort to work the difficult
passes and stretch the limits. If it were easy, everyone would be
doing it.

Message-ID: <974810.9249.qm@xxxxxxx.xxx.xxxx.xxx.xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"; format=flowed
VO-52 has been a very loud and easy to work satellite
since the recovery and change to the Dutch Transponder.
The CW beacon is very loud and you can usually find an
image of it elsewhere in the transponder passband.
If you are running full doppler control, you have probably
noticed that your settings (uplink calibration) have to be
changed from pass to pass. The beacon frequency is not constant
either so I suspect that the frequency source is not very
stable. Stability is usually a function of temperature so
it would appear that the temperature inside the satellite is
changing due to internal electronics and/or effects from the
sun. This would be something that the control team would be
aware of. Any feedback from them would be appreciated.
I do not recall that the India Transponder had a similar problem
but maybe someone else could comment on that. If it did drift, it
was only one or two hundred Hz. Initially the difference between the
India and Dutch Transponder was about 2KHz. Now it seems to vary plus
or minus 500 Hz or so. Maybe some others can comment on this.

Hi John,K8YSE
When AO40 was alive and well I had many QSO's
with the East coast of USA in Mode L/S with the
satellite down up to - 2.5 degrees belove the horizon
for me and for the station in contact with me.
The keplerian elements were the same for me and for
the stations in contact with me using both the same
tracking program InstantTrack.
We supposed that in particular situations of temperature
and humidity a duct is created over the surface of the see
permitting the contact belove the horizon
We can't investigate more deeply into the above
phenomenon because AO40 died.
I do not remember the call letter of many stations in
USA in contact with me under such circumstances
but if someone from the Est coast read this letter and
remember,........please replay.

Hi John, K8YSE
I notice that the Dutch Transponder suffers of non linearity and
distorsion probably due to the fact that the AGC of it has not
been designed like the indian transponder but apparently only
using a diode based limiter so that when a strong signal comes
in the distorsion occurs for all stations operating in the passband.
In a separate email I will send to you a mp3 file for a QSO made
between me and IW6OVD using the indian Transponder few
days before it failed and I am sure you will notice the difference
in linearity and quality of modulation with the actual Dutch
Transponder.
It should be very interesting to get some technical explanations
about from William PE1RAH but after the recovery of VO-52
I have not seen any comment from him on AMSA-BB
I have not investigated about the frequency stability of the Dutch
Transponder but I will do.
