ARLS006 73 on 73 Award Period Now Underway
Paul Stoetzer, N8HM, is sponsoring a new award for contacts made via
the UK Amateur Radio Educational Satellite FUNcube-1 (AO-73) to
promote activity on the satellite. It is called the 73 on 73 award.
The award period began on September 1.
More information on FUNCUBE may be found on the web at,
Requirements are simple: Work 73 different stations on AO-73 (SSB or
CW). There are no geographic restrictions on operating location, no
QSLs are required, and the award is free.
E-mail log extracts containing the call sign of each station worked
and the date/time (UTC) of each contact to, n8hm(a)arrl.net. Include
your mailing address.
The AO-73 inverting transponder uplink is 435.150-435.130 MHz (LSB).
The downlink is 145.950-145.970 MHz (USB). Use no more than 5 W to a
7 dBi gain antenna when accessing the AO-73 transponder.

JPL's Horizons Web Site will likely
have these objects in their data base
when launched. From there you can
get RA/Dec or generate AZ/EL for your
QTH. You can enter RA/Dec into NOVA
and it will track it like any other
celestial target. Not sure if other satellite
programs have this feature.

I have no idea why, but the majority of AMSAT guys seem to refuse to mention this website when people are trying to figure out tracking... http://www.n2yo.com/?s=7530|27607|24278|39417
Just put in your location and the link I gave you will bring up the four current workable satellites. It's all I've used the past few years... eventually I will get SATPC32 when I finally get my new antennas up and want to try automatic tracking.
Saw a fairly new ham posting on eHam needing help/advice about putting up an antenna in trees. I suggested he look you up, lives just 8-9 miles from you. NC4EF I think the call is.
Hope all is well... 73 for now,

"Control is the need of the fearful mind. Trust is the need of the courageous heart."
After wrapping up the W1AW/7 satellite activity from Arizona in the
last week, I compiled some statistics. First of all, thanks to all of
the stations that worked W1AW/7 in the past week. I was the only
satellite operator for W1AW/7 this time, and we didn't have VO-52
compared to the other W1AW/7 Arizona week in mid-March, but
things worked out well.
W1AW/7 logged 105 satellite QSOs in the past week. W1AW/7
worked 58 unique call signs in those 105 QSOs. Those stations
were located in 19 US states, 3 Canadian provinces (BC, ON, SK),
and 3 Mexican states (Chiapas, Colima, Puebla), in 4 DXCC entities
(W, VE, XE, CO). W1AW/7 logged QSOs with 47 different grids.
W1AW/7 made QSOs on the following satellites:
AO-7 - 5 QSOs
AO-73 - 19 QSOs
FO-29 - 35 QSOs
SO-50 - 46 QSOs
W1AW/7 only worked daytime SO-50 passes during the three-day
Labor Day holiday weekend (Saturday through Monday), and 2 AO-7
passes on Sunday. FO-29 and AO-73 were worked every evening,
at least one pass for each satellite, plus the daytime AO-73 passes
over the weekend (thanks AMSAT-UK and the FUNcube project!).
The SO-50 passes on Saturday and Monday afternoons were worked
from the DM33/DM43 grid boundary at a Phoenix city park (the park
I worked many satellite passes from, over several years), and the
other passes were worked from my back yard in DM43.
If you wish to receive a QSL card for working W1AW/7 in the past
week, please send your QSL request to ARRL. Over the next week
or two, the log will be uploaded to Logbook of the World, including
the grid locator(s) for each QSO.
Looking for a bit of help here. In reassembling my 9600 bps ground
station today for an upcoming launch I found two problems.
1) My IC910H goes into transmit on main band when I power it on, even
with nothing connected. It worked fine a month ago. Using the
4/5-power on factory reset clears the settings but it still transmits
when turned on. I'd appreciate any ideas of what else I can try, or -
can I send it to ICOM for repair.
2) A used KPC9612+ I bought from a local guy, which worked fine a few
days ago, now has a PTT problem. The PTT on pin 1 of the 15 pin 'high
speed' port 2 connector is inverted. It is ground when the TNC is idle
and goes off ground (not sure how far) when I send a packet. The PTT
light for port two works properly, red when PTTing, but the output pin
is inverted. I did note the backup battery appears dead because
settings like the PC interface baud rate don't survive a power cycle,
but I can't see how that should effect PTT polarity. As above, any
ideas about a setting the inverted that, or - where can I send this guy
for repair, would be appreciated.
These two could be related since the KPC and 910 were connected for a
month or so. Perhaps one failure caused the other. Just speculating.
Thanks in advance,
It was the first spacecraft to reach Saturn.
As I remember, the observations it made indicated more details in the
ring structure than could be observed by ground-based telescopes.
That was confirmed over a year later by Voyager 1.

I have two 5 foot fiberglass booms, and a 4 foot stainless steel insert for the booms. The insert alone weighs 20Lbs. Asking $125 (offers) plus shipping to your QTH. Pictures available upon request. Starting here before Ebay. Email direct.

Just a reminder that the award period for the 73 on 73 Award begins at
0000Z on September 1st, so begin keeping track of the unique callsigns that
you work on AO-73. When you reach 73 unique callsigns in your log, email me
at n8hm(a)arrl.net with a list of calls, date, and time worked (in UTC) and
your mailing address. I hope to have a website up soon with an example of
what the award will look like.
Some tips for working AO-73:
-Keep in mind the frequency drift on the transponder. The offset needed on
your transmit frequency is usually from +10 kHz to +16 kHz. This can vary
throughout the pass, requiring frequency adjustments if using computer
control. Many find manually tuning the uplink to maintain a constant
downlink to work better than computer control.
-I usually start a pass by trying to find myself come into the top
edge of the passband (145.970 MHz). To do this, I usually start
transmitting around 435.135 MHz and tuning up slowly until I can hear
myself enter the passband. Then I can move around the transponder
easily. Remember to tune your uplink to maintain an constant downlink
frequency (the opposite of FO-29).
-Keep power output down. The transponder has a very sensitive receiver
and a very active AGC circuit. Excessive uplink power will not make
your signal louder - it will only reduce that available for others on
the transponder. With a clear view of the horizon, 5 watts to an Arrow
or Elk is plenty for horizon to horizon coverage. Very slightly more
might be necessary if you are beaming through trees or other
obstructions, but try to keep power to 25-40 watts ERP.
Good luck! Who will claim the 73 on 73 Award #1?
