Hi Amsat's
For a homebrew polarity switch I suggest to read my article:
"Switching Four Polarizations on a 70 cm Crossed Yagi"
Part-1 in AMSAT Journal March/April 2007
Part-2 in AMSAT Journal May/June 2007
The above switching circuit allove to switch 4 polarizations V-H-RHCP and
LHCP on a crossed yagi having the elements spaced 1/4 wavelenght over the
boom and dimension of the feeding and delay lines can be scaled for 144 MHz
or any other band.
If someone is interested on it I can send a zipped pdf file of both the
above articles.

Hi Damon, WA4HFN
The pramplifier "seems" to kill the birdy because the preamplifier gain is
very high and so the birdy is belove the noise introduced by the
preamplifier itself.
I guess that without any signal on the band your S meter reading is well
above S-9 only because of the preamplifier noise that is apparently killing
the birdy.
If you reduce the gain of your preamplifier to get an S-meter reading of say
S-1 or S-2 without any signal on the band then the birdy will appear again.

Hi, Pat --
A great way to answer these questions more quickly is to use the
resource at http://oscar.dcarr.org There you will find real-time
reporting of the availability and mode of various satellites,
including AO-51. It includes info from around the world, so you can
often get an update 15 minutes before your pass begins. If we all
occasionally indicate our observations, especially when states change,
we can keep each other instantly up to date.

To improve the birdie issue on the TS-2000, be sure to keep your
antennas well away from the radio. I found the birdie less serious
recently, now that my antennas are 100' away.

Hi!
I will give a quick satellite demonstration to some local hams here in
Mexicali (DM22go) during the next AO27 pass at 2122 UTC this afternoon.
Please give XE2/WD9EWK a call if you are on that pass.
Thanks in advance, and 73!

Not sure this is the same explanation as Domenico gave, but, if the
birdie is internal to the radio, running an external preamp operates
the radio at a signal (plus noise) level above the level of the birdie.
The noise rises due to the exta gain but the noise floor actually can
be lower due to the increase in sensitivity (lower noise
figure). Does this make sense? In other words, the radio may go
from operating at -122 dBm to operating at -110 dBm (if preceded by
22-dB gain) and the receiver system (Rx+preamp) operate at -132 dBm
(not necessarily what your system will do). The birdie is not
amplified but the signal+noise is. This usually does not help with
birdies external to the radio.

That may be because the source of the birdie is near the radio and
not necessarily coming from the radio (e.g. nearby computers).
The FT-847 is famous for its internal birdies, but they are either
gone or diminished when I connect my eme antenna with tower-top
preamp. Some do not disappear so are probably being radiated from
the neighborhood.
A good test is to terminate the radio with a dummy load and see what
birdies remain (most likely are internally produced in the
radio). Then connect the antenna with preamp and see how many go
away or are greatly reduced. And see how many new ones show up! a
preamp can generate birdies from intermodulation products or
self-oscillation. So saying, RF is a messy business. ;-)
When I point the 2m eme array at 70-mi distant Anchorage the noise
floor rises (slightly). It drops if I swing in azimuth or raise
above 10-degrees elevation. In character the noise is not exactly
white noise but has a faint line-noise sound. Cities have a lot of lines. ;-)
73, Ed
PS: I am going to be interested to observe how many birdies my
Elecraft K3+DEMI 144/28 xvtr combo produce compared with the FT-847
on 144 (144-144.030 is unusable due to birdies)

We are completely reloaded and operational, in about 24 hours.
145.92/435.3 repeater is running with 67 Hz tone required to activate,
and will stay on for 2 minutes at a time. Output is 740 mw and subject
to change. We may have to adjust some other settings over the next day
or two. Please use the webpage at http://oscar.dcarr.org/ to post
reports. For some reason very few US stations use this. Please do as it
is impossible for us to listen to every pass.

Hi!
Thanks for the QSOs during the last AO27 pass. It was nice to hear much of
North America on the pass. Even Larry XE2/KI6YAA from another part
of this city.
I do not know if I will work any of the upcoming AO51 passes,
since I need to make my drive home sometime this afternoon or
evening. Apparently there has been
a lot of rain in my home
city Phoenix.
Thanks to everyone who made QSOs with XE2/WD9EWK over the past
couple of days. 73!

UK Space Agency to launch CubeSat
The UK Space Agency has announced a one-year pilot programme
to design and launch a CubeSat and is running a competition for
ideas for payloads.
This miniature, cube-shaped satellite will allow the UK to test
new space technologies and carry out new space research 'cheaply'
and quickly.
The pilot programme, named UKube 1, will use a spacecraft platform
that is currently under development by the company Clyde Space
Ltd and will involve a competition amongst companies and academic
groups to come up with the most innovative ideas for payloads.
The winning payloads will be launched on the satellite in mid 2011.
Companies and academics who are interested in designing a payload
can contact the UK Space Agency for more information.
There is another CubeSat under construction in the UK called
FUNcube.
It is being built by AMSAT-UK and the hardware will be shown at
the AMSAT-UK International Space Colloquium in Guildford
July 31 - Aug 1.

+ Clint, K6LCS and Gordon West, WB6NOA will be giving a public AMSAT
demonstration and presentation from the award-winning amateur radio
booth at the Orange County Fairgrounds on August 5, 2010 at 5:45PM PDT.
+ The Scouting SpaceJam-4 Weekend will be on August 6-8, 2010 at the
Chanute Air Museum in Rantoul IL (between Chicago and Champaign, IL).
Amateur radio features include an APRS balloon launch transmitting on
144.39 MHz every minute under the call sign, W9YJ-11 and an ARISS
contact with the scouts. The ISS-direct-to WB9SA contact is sched-
uled for a 36 degree elevation pass on Sat 2010-08-07 15:07:14 UTC.
More information about SpaceJam-4 can be found at:

+ Stu, WA2BSS reminds interested amateur satellite operators that the
the dates for the next two Hudson Valley Satcom nets are Aug. 5 & 19.
The 2 M repeater used is:146.970 MHz (2M Pl. 100) Time: 8PM EDT, or
2400 UTC. The EchoLink node is N2EYH-L. More info: www.hvsatcom.org.
+ Bruce, VE9QRP is asking for input from amateur satellite operators.
He is designing a microcontroller system for doppler tuning portable
radios. He is looking for information regarding which HTs or mobile
radios are CAT-controllable. He is testing this concept with an TH-D7A
and reports it works well. Bruce's e-mail is ve9qrp_at_gmail.com.
His web page is at: http://ve9qrp.blogspot.com. He demonstrates his
project in a video at: http://www.youtube.com/user/VE9QRP.

To All RADIO AMATEURS
BID: $ANS-213.04
In association with Tom Webb, WA9AFM/5, President, Oklahoma City Autopatch
Association, the North Texas Balloon Project would like to dedicate their
Launch No. 18 to the memory of fellow ham, John Mark "Rob" Robbins.
Just two weeks ago, John Robbins, NO5X, became a Silent Key. John was a
founding member of the Near Space Exploration Group in the OKC/Tulsa area.
We conducted several balloon launches from OKC until John's health
prevented his participation and leadership. It was John's goal to
do a record setting
flight for an amateur radio balloon. He came very close, but never
succeeded.
The John Mark Robbins Memorial Flight will be launched by the North
Texas Balloon Project (NTEXBP) at about 8:30 am CDT on August 7, 2010
from the municipal airport in Hillsboro, Texas, just south of Fort Worth
and Dallas. The public is invited to come out to the Hillsboro
Municipal Airport, located at Exit 3 on Interstate Highway 35W,
to watch the launch. The back up launch date is August 14, 2010.
Three payload packages containing sensors and amateur radios will be
carried to nearly 100,000 feet in about 90 minutes by a helium balloon
and return via parachute in about 50 minutes. Mobile recovery teams
will use position reports from the onboard GPS and APRS transmitter on
144.390 MHz and radio direction finding techniques to recover the payloads.
A cross band repeater will be activated soon after launch. Uplink is 4
45.800 MHz and downlink is 147.560 MHz. At the peak altitude ham radio
operators from Texas, New Mexico, Oklahoma, Arkansas, Louisiana, and
Kansas can contact each other using the cross band repeater.
The third payload of the flight is a ten meter beacon operating on a
frequency of 28.274 MHz. The antenna is a home brew loop and the
transmitter will be running approximately 1 watt. This beacon may be
heard world wide if the band is open. Please report reception and we
will happily QSL the event. Email webmaster@xxxxxx.xxx or kdvickers@xxx.xxx
Pre-launch activities will begin about 7:00 am CDT with the HF Launch
Net on 7260 +/- 5 KHz, LSB beginning around 8:00 am CDT. Follow us on
HF radio or on Twitter@xxxxxx .
Saturday's launch will show on APRS as W5SJZ-11.

According to NASA's Web site, more than 500,000 pieces of "space junk" are
tracked as they orbit the Earth. Although most of the orbital debris is
relatively small, some 20,000 pieces are larger than a softball, which NASA
keeps track of because scientists say it poses a serious threat, especially
to the International Space Station.
