Content-Type: text/plain; charset="iso-8859-1"
I bought an Icom AG-35 preamp about a year ago. The fellow ham advertised it
as virtually brand new and it was/is. I planned to use it this summer with a
TS-2000 which doesn't supply 12v voltage to the coax to power a preamp as
other xcvrs do. I used a Mirage KP2 unit to inject power to the coax to
drive mast mounted the preamp. When I turn the power on there seems to be
little or no noticeable difference in background noise and worse than that I
cannot here any signals on FO-29 downlink, and I know the bird has been
active. Any suggestions? Is the preamp fried? I can't even get the weather
proof case off to trouble shoot, not that I'd know what to look for. Any
suggestions on repair?

Postponed ELaNa Launch From Vandenberg Scheduled for August 14
The August 2, 2012 Atlas V rocket launch with a combination of 11
satellites from Vandenberg Air Force Base in California for the US
Government and NASA ELaNa university cubesats was scrubbed due to a
range instrumentation problem. This launch is now scheduled to lift
off from Vandenberg on August 14.
The primary mission will launch a pair of US Navy Ocean Surveillance
Satellites (NOSS). These satellites carry equipment to track ships
and aircraft by triangulation of radio transmissions. The two NOSS
satellites have a combined weight of 6500 kg. They will separate
a few days after being placed into a 1100 km circular orbit at 63?
inclination.
This is the first Atlas V launch with modified helium tanks in the
Centaur upper stage. The change has created room in the aft skirt
to accommodate 8 P-POD dispensers for cubesats. This launch carries
11 cubesats, to be released into 470 x 770 km, 63? orbit about 3 hours
after launch and following maneuvers by the Centaur upper stage.
The ELaNa Cubesats aboard are:
+ CINEMA (Cubesat for Ion, Neutral, Electron, Magnetic fields)
o Downlinks for engineering telemetry and command are in the
2400-2450 MHz range; Science telemetry is in 2200-2300 MHz
range.
+ CSSWE (Colorado Student Space Weather Experiment)
o Downlink 437.345 MHz, 9k6 with AX25
+ CP5 (PolySat)
o Downlink 437.405 MHz at 1 watt, AFSK on LSB AX.25 over NRZI at
1200 baud, every 2 minutes, begins 3.5 hours after first turn-on.
+ CXBN (Cosmic X-Ray Background Nanosatellite)
o Downlink 437.525 MHz, GFSK, AX.25
The US Government Satellites aboard are:
+ Aeneas
o First cubesat to deploy 2.4 GHz Dish Antenna. WIFI transmitter
will transmit on 2425.0 MHz with 1 watt of output power.
o Downlink 437.600 MHz AX25 1200 bps beacon every 10 seconds and
spread spectrum two-way link elsewhere in the 70cm band.
+ ORSES (ORS Enabler Satellite)
+ Horus
+ Re
+ Aerocube 4A, 4B, 4C

ESA Announces New Educational Cubesat Initiative
AMSAT-UK has received notice that the European Space Agency's
Education Office is inviting the CubeSat community to send their
notifications of interest for a new initiative involving the dev-
elopment of educational picosatellites and the provision of de-
ployers and launch services. The call closes on 7 September 2012.
Following the successful launch of seven CubeSats on Vega?s maid-
en flight in early 2012, ESA has decided to pursue further educa-
tional CubeSat-related activities.
In order to gather valuable information that will help better de-
fine the terms of its initiative, ESA?s Education and Knowledge
Management Office needs to get an overview of the level of interest
both from educational CubeSat developers and from commercial suppli-
ers that are eligible to participate in the programme.
Call 1: Educational CubeSat development
---------------------------------------
This call for Notification of Interest is open to institutions from
ESA Member States and Cooperating States which intend to develop
CubeSats for educational purposes.
Teams interested in participating are invited to send their Notifica-
tion of Interest to cubesats@xxx.xxx
The email subject should be: ?CubeSat opportunity ? Name of the
proposed CubeSat project? and should be sent before 12:00 CEST
7 September 2012.

Welcome to Gale Crater - Mars Science Laboratory Curiosity Lands
With Curiosity now safely on the surface of the Red Planet after its
August 6 entry, descent and landing in Gale Crater, NASA's Mars Sci-
ence Laboratory began its planned primary one-Martian-year (98-week)
mission of discovery and exploration.
Re-live the entry, descent and landing at Jet Propulsion Labs:
http://www.youtube.com/watch?feature=player_embedded&v=giZY2JuuhZA
The Curiosity Mars Descent Imager (MARDI) captured the rover's descent
to the surface. The instrument shot 4 frame per second video from heat
shield separation to the arrival on the ground. The last few seconds
show the dust being kicked up as the flying skycrane approached the
surface:
http://www.youtube.com/watch?feature=player_embedded&v=UcGMDXy-Y1I
Watch the arrival on Mars in an exciting movie trailer format:
http://www.universetoday.com/96646/curiositys-awesome-landing-trailer/
This week the rover checked its health and determined its location,
orientation and tilt on the surface of Mars. All initial spacecraft
activities appear to have been completely nominal. The JPL control
team next commenced with firing all of Curiosity's pyrotechnic de-
vices for releasing post-landing deployments.
Spring-loaded deployments, such as removal of dust covers from the
Hazard-Avoidance cameras (Hazcams) occurred shortly after landing en-
abling Curiosity to acquire images with its front and rear Hazcams.
Additional post-landing checkout activity included testing of the
UHF telecommunications system and rover motor controller assembly.
Approximately five megabytes of data were successfully relayed back
to Earth from NASA's Mars Odyssey spacecraft during the first day.
Curiosity landed facing east-southeast within Gale Crater, with a
heading of 112.7 degrees (plus or minus five degrees), and a few
degrees of tilt.
The latest official mission information, photos, and video is always
posted at: http://www.jpl.nasa.gov/msl/ - and -

Pioneer of Radio Astronomy Sir Bernard Lovell Dies
The BBC reports pioneering astronomer and physicist Sir Bernard
Lovell has died aged 98. He was the founder of University of Man-
chester's Jodrell Bank Observatory. Jodrell Bank is dominated by
the iconic 76m (249ft) Lovell Radio Telescope, was completed in
1957. he telescope and his other contributions to radio astronomy
led to him being knighted in 1961. He continued to come in to work
at the Observatory until quite recently when ill health intervened.
The structure remains the third largest steerable telescope in the
world and plays a key role in global research on pulsating stars,
testing extreme physics theories including Einstein's general theory
of relativity.

Raytheon Building the New Space Fence Radar
The Air Force expects to deploy its $3.5 billion space fence sys-
tem by 2017 to improve its space debris tracking ten-fold. As many
as 200,000 pieces of orbital debris can be tracked with the S-band
radars.
Lockheed Martin competed with Raytheon for the contract mandating a
scalable, solid-state S-band radar with a wavelength frequency capa-
ble of detecting objects far smaller than the half-century-old Air
Force Surveillance System the new system will replace.
Lockheed Martin demonstrates their prototype space fence in a video:
http://www.youtube.com/watch?v=7SJdN90vT04&feature=player_embedded
Raytheon won the contract which they describe as multiphase acquisi-
tion program, leading to the delivery of up to three, globally posi-
tioned, S-band radars operating in the U.S. Space Surveillance Net-
work. Raytheon posted information on-line at:

There's an App For That - ID Visible Satellite Flyovers
WhatSat - Satellite Explorer helps you identify and learn about sat-
ellites that you see passing overhead in the night sky. It can also
be used as a satellite spotting aid. The satellite catalog includes
150 or so of the brightest orbiting objects as identified by NORAD.
For each satellite listed there is a description and an image (when
available).
The first mode of operation allows you display a list of currently
visible satellites if you see one passing overhead. The app shows you
a ground track of the satellite to give you some idea where and how
far away it actually is.
The second mode of operation gives you a list of what is visible
with a visibility indicator, azimuth, and elevation to help you find
satellites. This includes a map view of the ground tracks.
WhatSat requires cell service or WiFi to access the server that
does satellite flyby calculations.

enrolled in at least half time status shall be eligible for the stu-
dent rate for a maximum of 6 post-secondary years in this status.
Contact Martha at the AMSAT Office for additional student membership
information. And with that, please keep in mind like Earth, Mars has
four seasons because the planet tilts on its axis. The seasons vary
in length because of Mars' eccentric orbit around the sun. In the
northern hemisphere, spring is the longest season at seven months.
Summer and fall are both about six months long. Winter is only four
months long. On average, the temperature on Mars is about minus 80
degrees F (minus 60 degrees C). In winter, near the poles tempera-
tures can get down to minus 195 degrees F (minus 125 degrees C). A
summer day on Mars may get up to 70 degrees F (20 degrees C) near
the equator, but at night the temperature can plummet to about minus
100 degrees F (minus 73 C).

Hi Rick
Check the KP2RC unit output volt if it the same as the input supply volt !
This volt suppose to be same on both the input and output coax connectors
of the KP2RC control unit .
Check the RCA phone jack at KP2RC unit if there any bridge or metal? twist
any short in this jack will? drop the output volt to Zero .
Hope this wll help

First, make sure that nothing else that might block DC is in line between
the power inserter and the preamp. Then, have someone go up the ladder and
listen as you turn the power feed on and off. They should hear a distinct
click as the relays in the preamp engage. Tune to a distant repeater, and
you should see at least a 2 - 3 S-unit increase when the preamp is on.
How much current is the KP2 capable of supplying? If it can't pull in those
relays, the preamp will remain in bypass mode.

Rick,
I suggest you use a VOM or DMM to measure the current drawn on 12 volts
going to the power injector. If everything is connected correctly It will
draw 30-200 mA. Confirm that you have continuity in your coax. Some
lightning arrestors have a DC block built in. It is best to test it with a
short run of coax between the preamp and the power injector at the radio
while listening to a local repeater to see if the signal increases when you
apply power to it. If it operates then you can proceed to determine if there
are problems with the coax to the antenna, not carrying the 12 VDC.

Hi All,
Somebody please clarify---I may be wrong, but I thought the Icom preamps did
the following with Icom radios:
In receive, 12V is powered up the coax. Device is powered, preamp is ON.
In transmit, the 12 power feed is stopped. Device is not powered, and it's
bypassed during xmit.
If this is the case, it complicates greatly the use of Icom preamps on
non-Icom radios (means there isn't a typical RF-sensed bypass circuit, which
means it would be easy to blow in a non-Icom radio).
Am I remembering this wrong?

You are unfortunately correct and this was not clear in any manuals, at
least to me, when I began to use an icom preamp for 435 on my TS-2000.
Hence, a blown preamp! There is a guy I found on eBay that sells a switching
box that plugs into the external control port on a TS-2000 and gives you a
relay control RCA out cable for each of the VHF/UHF bands, even 1.2 if you
have it. You can control either amps or preamps. I may look into this, once
I figure out how to repair the preamp if it is even repairable, but I think
it is.
Thanks for all the input everyone. At the end of the day I wish I had my 847
as I feel it may be a more user friendly rig for sats at least for
controlling external preamps.

Hi Mark,
That is the way they're supposed to work. +12v receive - 0v on xmit.
It is fine with a Yaesu FT-736R using the built in preamp feed system -
power up the coax. Just have to watch out for any DC block.
It also would work with a Yeasu FT-847 if it had 1296.....
I had one for a while. I found I had to open it up and retune as it was set
for the low end of the 23cm band?!? My biggest problem was that it was only
good for about 15 watts. I had to use it after my DL2AM 80 watt amp....
Mike
