Hi all,
Please this is just a technical matter :-)
Here this afternoon with Yubileiny AOS at 1430 UTC and
AO-51 with AOS at 1441 UTC in Copenhagen, the downlink
spectrum of Yubileiny was strong when listening to
the AO-51 frequency.
Hello Ib.
Oh dear, no frequency co-ordination!
A week or so ago I looked at the transmission from Yubileiny and it was
almost constant amplitude over a 4800Hz bandwidth slowly reducing beyond
that.
If you allow for the practical width of our IF filters and the fact doppler
can shift the frequencies by +/- 10kHz, at 435MHz, then Yubileiny and AO-51
will encounter each other from time to time.
Thankfully the orbits are very different so it's a minor (but avoidable)
inconvenience.
Thanks
David

Hi folks,
The next model of an amateur radio satellite is just around the corner.
Thanks to the great folks from the TU Delft (Delfi-C3 team) and their timely
information, a new cardboard model in the scale 1:1 is almost done. I am
still playing with the antennas and writing the instructions. You can see
the almost completed prototype at:
http://www.wincube.ca/Delfi.html
The model will be available as pdf files for you to print (and cut and glue)
in the next few weeks from the Delfi-C3 website. Will let you know. So get
your glue ready and during those rainy nights build a great model for the
club station or your radio shack.
Hope you look it.
73, Stefan VE4NSA

Hi!
Now that I've been back in Phoenix for a couple of days, I can
scribble a little about my Saturday activities. From a hamfest
in central Arizona in the morning to more satellite operating at
two other locations in the state, it was a fun day.
Saturday morning at the Prescott (AZ) Hamfest (grid DM34sn):
http://maps.google.com/maps?f=q&hl=en&geocode=&q=34+34.429+n+112+29.790+w&ie=U
TF8&ll=34.007135,-112.129211&spn=1.835081,2.570801&t=h&z=9
I had an AMSAT table at the 2nd annual Prescott Hamfest, presented
by the Yavapai Amateur Radio Club and the Verde Valley Amateur Radio
Association (two central Arizona radio clubs). This hamfest was in
an area with a few basketball courts surrounded by buildings and a
small hill. My table was at the entrance to the hamfest area, so
anyone walking into the hamfest area saw it. The hamfest was
officially going to run from 8am to 2pm local time (1500-2100 UTC),
but people were milling around the area just before the official
opening time and by 2030 UTC all of the sellers had left or were
packing up. A small event, but a nice way to avoid the heat in
the desert back home in Phoenix.
I worked stations on the two morning AO-51 passes (1439 and 1619
UTC) using the normal 145.920/435.300 MHz transponder. The first
station in the log on the 1439 UTC pass was another hamfest -
Richard N2SPI at the Rochester (New York) hamfest. Thanks for
the contact, to start out my day! I was able to make 11 more
contacts with stations across the USA and Mexico. On the later
pass at 1619 UTC, the low elevation (maximum elevation of 14
degrees) and local surroundings (school gymnasium and hills) made
this one tough. I only made 2 QSOs near the middle of the pass.
Along with the AO-51 passes, I did attempt the VO-52 pass at 1754-
1807 UTC - a western pass, with maximum elevation of 70 degrees. I
could hear myself, but unfortunately made no QSOs. I think my AOR
AR8200Mk2B receiver has sharp SSB filtering, and not enough options
for tuning steps without using extremely small steps to help tune the
downlink signals. My FT-817ND is more than enough to be heard by that
satellite. I'm still working on this, and may try another receiver or
possibly another FT-817 as a portable all-mode full-duplex satellite
station.
Once the hamfest's raffle prizes were awarded after 2015 UTC, I
went to get lunch and drive north toward the DM34/DM35 grid
boundary for several passes.
Saturday afternoon on the DM34/DM35 grid boundary (specifically,
grids DM34tx and DM35ta):
http://www.geocities.com/va7ewk/ao51/20080419-DM34tx_DM35ta_GPS_readout.jpg
http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+0.00+n+112+23.132+w&jsv=10
7&ie=UTF8&ll=34.288992,-112.412109&spn=3.830102,7.734375&t=h&z=7
This spot, off a state highway, is about 15 miles/24km south of
the I-40 freeway just inside the Prescott National Forest and about
35 miles/56km north of the hamfest site. I was at the same location
on 19 April after another event in Prescott, so I knew what to
expect in terms of working the satellites. I was able to work 2
AO-27 and 2 SO-50 passes from here, one pass for each satellite in
each direction, before I drove to Kingman for the evening AO-51
passes.
The first passes to the east (AO-27 at 2128-2135 UTC, SO-50 at 2136-
2148 UTC) had the typical activity from all over the USA and Mexico.
I heard - and worked - Allen N5AFV on Enchanted Rock in Texas (grid
EM00), along with 8 others (2 Mexican and 6 US stations) on AO-27.
For the SO-50 pass, I worked N5AFV again, along with 4 other US
stations and 1 Mexican station.
After updating my logbook with all the contacts I had made to this
point, I stuck around this location for the western passes - AO-27
at 2308-2315 UTC, SO-50 at 2315-2329 UTC. In keeping with what
appeared to be the trend for the day, I only worked 3 stations on
each of those passes. When SO-50 went out of range, I quickly
secured my gear and made the 110-mile/177km drive to Kingman so I
could find a spot on the DM25/DM35 boundary in time for the evening
AO-51 passes.
Saturday evening in Kingman, Arizona, near the I-40 freeway and
old route 66 on the DM25/DM35 grid boundary (specifically, grids
DM25xf and DM35af):
http://www.geocities.com/va7ewk/ao51/20080531-DM25xf_DM35af_GPS_readout.jpg
http://maps.google.com/maps?f=q&hl=en&geocode=&q=35+13.437+n+114+0.00+w&ie=UTF
8&ll=34.520136,-113.186646&spn=3.647604,5.141602&t=h&z=8&iwloc=addr
This location is on the east end of Kingman, north of the I-40
freeway and at the west end of the longest remaining stretch of
the old US route 66 that once went from Chicago to Los Angeles.
There are lots of mountains around Kingman, and this location was
in the area where they would bother me the least for satellite
passes while on the DM25/DM35 boundary.
I found an empty lot east of Route 66 near railroad tracks, where
I parked and took a picture of my GPS receiver's display on the
rear bumper of my truck before setting up my equipment. I waited
for the first AO-51 pass at 0149-0204 UTC, an eastern pass with
maximum elevation of 45 degrees. A very nice pass. I planned to
use the second AO-51 transponder (145.880/435.150 MHz) up here,
and that worked well for this pass.
During that 15-minute pass, I worked 11 stations - 8 in the USA,
3 in Mexico. I was told there was more activity on the normal
145.920/435.300 MHz transponder while I stayed on the second
transponder, but the activity was steady and I had no need to
move over to the normal transponder.
When AO-51 returned for the 0329-0342 UTC pass, a lower pass to
the west (maximum elevation of 19 degrees), I talked to myself for
several minutes on the second transponder. When it was becoming
apparent nobody else was going to show up, I moved over to the
normal transponder and made 3 contacts during the remaining time.
I logged contacts with two California stations and Gerry VE4GTB in
Winnipeg - the last contact, and only Canadian contact, this day.
Hearing Gerry call me was a huge surprise, as I did not realize the
footprint went that far east on that late pass. After the pass, I
packed up my gear, stopped for a quick dinner, and made the 3.5-
hour drive back home to finish this busy day.
I made a total of 49 contacts from these 3 locations - 14 from the
hamfest, 21 from the DM34/DM35 grid boundary, and 14 more from the
DM25/DM35 grid boundary. DM25 is the 12th different Arizona grid I
have operated from since March. If anyone who worked me from these
locations wants to receive a QSL card, please e-mail me with the QSO
details. I'll drop a card in the mail if you're in the log.
Including the drive from Phoenix to Prescott on Friday evening and
looking around Prescott and Kingman, I drove a total of 530.6 miles
(853.7km). Thanks to Terry KB7TRE with the Yavapai Amateur Radio
Club for inviting me to the hamfest, Ray W1OTH (a YARC and AMSAT
member) for helping me at the table during the hamfest, and to all
stations making contacts with WD9EWK during the day and evening.
73!

I think the ARRL one is only for USA callsigns as it uses the FCC

Hmmm... Actually, I did some digging and everything related to QRZ.com

Perhaps the outage is just some kind of cosmic coinky-dink?

Hello All,
Just listened to RS-30 pass over VK. Only heard CW telemetry on 435.315,

Hi Art,
DO-64 / Delfi-C3 is currently in science mode, transmitting telemetry on
145.930MHz BPSK AX.25. The satellite will remain in this mode for two more
months, before she will be switched to transponder mode. We have briefly
tested the transponder already though, so we know it works hi :)
Have fun on field day!
73 on behalf of the Delfi-C3 team,

Hi Stephan,
Model looks great. Are there similar models for other satellites?

Dear All,
I'm Hiroki Ashida at Tokyo Institute of Technology (JQ1YCZ). I'd like
to inform you about our satellite's operation.
We started a long-run (continuous 24hours) of the APD sensor at 11:30,
Jun 3 (UTC) and it will be turned off on 11:30, Jun 4(UTC). During the
APD is turned on, the APD status packet can be heard everywhere in the
world.
FM packets are transmitted on 437.475MHz and packet formats are
available in the following web-page.
http://lss.mes.titech.ac.jp/ssp/cute1.7/fm_mode_apd_e.html
4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A-D0-30-77-B8-03-16-99
For exapmle, according to an above APD status packet we can obtain
informations as;
4A-51-31-59-54-43-3E-4A-51-31-59-43-5A-3A : Header(JQ1YTC>JQ1YCZ)
D0 : APD Packet ID (Fixed)
30 : Status Code
APD Status : Operational
HV Status : Set Value = Output Value
Temp Correction : Active
Data Mode : Counter Valid
Detector : APD A
APD Gain : Gain 30
Threshold : 219mV
77 : Temperature
0x77 = 119 -> (119/255)*91.712-48.569 = -5.7 [degC]
B8 : High Voltage
0xB8 = 184 -> (184/255)*396.5 = 286 [V]
03-16-99 : Counter
0x1699 = 5785 -> 5785 * 2^3 = 46280
Latest TLE from NORAD is;
Cute-1.7 + APD II
1 32785U 08021C 08154.79960534 .00000134 00000-0 24077-4 0 664
2 32785 097.9934 214.7536 0014695 178.3289 181.7972 14.81362228 5275
Though the observation data will be stored in FRAMs, we'd like to know a
real-time status of the APD during the observation. Your kind reports
will be highly appreciated!
Best Regards,
Hiroki Ashida
Cute-1.7 + APD II

Dave,
After looking at the AMSAT Co-ordinator list, N0VSE is near Denver and he
seems to be the closest. As the NJ and Eastern Co-ordinator, I am always
interested in what the other areas are doing to Fly the AMSAT flag. Looks
like you have an interesting project going on. I copied N0VSE with this note
and hopefully you can find out who might be closer to you and assist.
Good luck!
Dee, NB2F
NJ Co-ordinator.
