Well, I have spent a good portion of the day trying to find preamps for my
M2 leopack. I read that at the very least putting one on the 70cm antenna
will help a lot with the receive. But, I just can not find any. Most of the
names I came across must have went out of business because their website are
no longer in existence. ?Any suggestions out their from you season operators
out there? The ones that I got last post I couldn't find.?Thanks

I have SSB Electronic preamps that I bought right from the USA distributor.
They're not cheap, but they work flawlessly.

Nayif-1 Launched
The Indian Space Agency ISRO successfully launched the amateur radio
satellite
Nayif-1 along with 103 other satellites, a record for a single launch.
The PSLV-
C37 lifted off from the Satish Dhawan Space Centre, Sriharikota, Andhra
Pradesh
at 03:58 UT on Wednesday, February 15, 2017.
Nayif-1 started transmitting about an hour after launch and radio
amateurs in
the west of the USA reported the first signals. The first frame of data
received
at the Data Warehouse was from Christy Hunter KB6LTY. Telemetry data was
also
received by WA6FWF, KA7FVV, WC7V, NC7V, K6FW, KE7QPV, WA9ONY, W5PFG,
KK6AYK.
Ken Eaton GW1FKY reports he received his first frames of data when the
satellite
came in range of the UK at 10:07 UT.
The satellite looks to be in perfect health and it was placed in
autonomous mode
before the end of the first day in orbit. Just like FUNcube-1, this mode
has the
spacecraft sending high power telemetry when in sunlight and with the
SSB/CW
transponder active when in eclipse. Already many contacts have been made
through
the transponder. As expected, the frequency stability of this spacecraft
is much
better than its predecessors.
A new post-launch set of TLE?s has been issued by the launch authority
and it
can be downloaded from http://amsat-nl.org/download/NAYIF_TLE.txt
Please note that these numbers are not based on JSpOC observations so we
do not
yet have a valid catalog number.
During the Launch and Early Operation phase (LEOP) of the mission, the
Nayif-1
command team have been headquartered at the American University of Sharjah
Ground station in the United Arab Emirates. They have been very grateful
for all
the telemetry received from around the world. It has proven to be immensely
useful to the team in checking that the spacecraft is functioning
correctly.
Our world-wide network has greatly impressed the many professionals that
have
been watching our activities. Already more than 100 ground stations are
submitting data to the Nayif Data Warehouse. Please continue uploading
the data
as this will further enhance our knowledge about the spacecraft and the
space
environment through which it is traveling at 7.6 km/s.
The Nayif-1 Data Warehouse has been updated and now includes the Whole
Orbit,
High Resolution graphs and the upload ranking. It also includes telemetry
details from the ADCS sub-system ? this is called the iMTQ and is
capable of
actively magnetorquing. Over the coming days, we will be further
tweaking the
warehouse, so bear with us if it is unavailable for short periods of time.
Background
Nayif-1 has been developed by the Mohammed bin Rashid Space Centre
(MBRSC) and
American University of Sharjah (AUS). The UAE?s first Nanosatellite was
developed by Emirati engineering students from AUS under the supervision
of a
team of engineers and specialists from MBRSC within the framework of a
partnership between the two entities, aiming to provide hands-on
experience to
engineering students on satellite manufacturing.
The spacecraft includes a U/V linear transponder and telemetry
transmitter. It
employs enhanced oscillator circuitry and includes an active attitude
determination and control system.
The operating frequencies for the spacecraft are:
Telemetry
145.940 MHz using 1k2 BPSK to the FUNcube standard.
SSB/CW Transponder
Uplink on 435.045 ? 435.015 MHz
Downlink on 145.960 ? 145.990 MHz

Satellite Operators on the Road
ZF, CAYMAN ISLANDS. Scott/KA9P and Ron/W9XS will be active as ZF2SC and
ZF2FB, respectively, from the Cayman Islands between February 22-28th.
Activity will be on 40/30/20/17/15 meters and the satellites. Operations
will typically be CW, with a KX1 or KX3, and Buddipole beams or verticals.
QSL via their home callsigns or LoTW.
6E, MEXICO. A group of Ham Radio operators from Southern Mexico will be
operating from some Mayan archaeological sites from the Mexican States
of Yucatan, Campeche, Tabasco, Chiapas and Quintana Roo, using the special
callsign 6E3MAYA between March 18-21st. Activity is to commemorate the
Spring Equinox which is so important for the Mayan culture. Activity will
be on 80-6 meters on CW, SSB, the satellites and the Digital modes. QSL
via XE3N.
C6, BAHAMAS (IOTA Op). Operators John/M0IDA, Rob/M0VFC and Steve/M1ACB
hope to be active as C6APY from Little Harbour Cay, Berry Islands (NA-054,
WW Locator FL15do). They will fly into the Bahamas on March 2nd, but it
will take them a couple of days to get to the island, so they hope to be
active around March 4th - but this is very much weather dependent, as is
the whole operation. They will fly back to the UK on March 12th, which
means they will need to de-rig on the 10th or 11th, again varying according
to the weather. Operation probably won't be 24/7 - they will do as much
operating as they can, but eating and sleeping is back on the boat, there's
only three of them, and they will probably want to go for the occasional
swim as well. They will be running up to three stations simultaneously,
all Elecraft K3s at 100W. They will be generator powered and have to carry
the full week's fuel with them on the boat, hence no amps. They are
expecting that most QSOs will be on 40-15 meters; they will monitor the
higher HF bands as well and may venture on to 10/12m if propagation favors
them; similarly they may throw up an 80m dipole, but don't expect to do
very much, if anything, there. There will definitely be CW (op M0VFC) and
SSB (ops M0IDA and M1ACB); they may also do some data if time permits.
They should be active on some satellite passes with hand-held antennas:
the FM birds will only cover parts of the USA, and not EU, so they will
attempt some FO-29 passes as well. They are not satellite experts though,
so be patient with them. QSL is via M0OXO's OQRS system. They will upload
the logs to ClubLog and LoTW regularly throughout the trip, assuming all
the kit plays nicely. Watch Twitter for any other updates:

Amateur Radio on the International Space Station Contact Opportunity
Call for Proposals
Proposal Window February 15 - April 15, 2017
The Amateur Radio on the International Space Station (ARISS) Program is
seeking
formal and informal education institutions and organizations,
individually or
working together, to host an Amateur Radio contact with a crew member on
board
the ISS. ARISS anticipates that the contact would be held between
January 1,
2018 and June 30, 2018. Crew scheduling and ISS orbits will determine
the exact
contact dates. To maximize these radio contact opportunities, ARISS is
looking
for organizations that will draw large numbers of participants and
integrate the
contact into a well-developed education plan.
The deadline to submit a proposal is April 15, 2017. Proposal
information and
documents can be found at www.arrl.org/hosting-an-ariss-contact.
The Opportunity
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts
through a
question-and-answer session.
An ARISS contact is a voice-only communication opportunity via Amateur
Radio
between astronauts and cosmonauts aboard the space station and
classrooms and
communities. ARISS contacts afford education audiences the opportunity
to learn
firsthand from astronauts what it is like to live and work in space and
to learn
about space research conducted on the ISS. Students also will have an
opportunity to learn about satellite communication, wireless technology,
and
radio science. Because of the nature of human spaceflight and the
complexity of
scheduling activities aboard the ISS, organizations must demonstrate
flexibility
to accommodate changes in dates and times of the radio contact.
Amateur Radio organizations around the world, NASA, and space agencies in
Russia, Canada, Japan and Europe sponsor this educational opportunity by
providing the equipment and operational support to enable direct
communication
between crew on the ISS and students around the world via Amateur Radio.
In the
US, the program is managed by AMSAT (Radio Amateur Satellite
Corporation) and
ARRL (American Radio Relay League) in partnership with NASA and CASIS
(Center
for the Advancement of Science in Space).
More Information
Interested parties can find more information about the program at
www.ariss.org
and www.arrl.org/ARISS.
For proposal information and more details such as expectations, proposal
guidelines and proposal form, and dates and times of Information
Sessions go to

mounting the antenna only about 10 feet off the ground, 50 foot will be
enough to go into the shack. I wanted to purchase RG8x but read that the
best way to go is with LMR400. What I dislike about it is that its much
wider and very stiff, and will make it difficult around bends. I also have
the Az/alt rotator which I will have to loop each antenna to have enough for
turns. Any other suggestions out there for an alternative to LMR-400?Thanks

Hi!
Now that the Yuma Hamfest has wrapped up, I will head home in the
morning. On my way home, I will stop on the DM22xq/DM32xq grid
boundary about 20 miles/32km east of Yuma AZ, along old US-80 and
north of the I-8 freeway. I am hoping to be out there for the
SO-50 pass just before 1500 UTC, but may not be on until the 1603
UTC FO-29 pass. I am planning to try working passes for 1 to 3
hours from there, before I resume my driving home. Hopefully the
rain that has been hitting southwestern Arizona for the past 24
hours will be done by the time I get on the road in the morning.
73!

Hi,
We are doing some work to integrate the registration on the FC warehouse
with the Nayif database, please bear with if you find that the FC warehouse
in unavailable for short periods. The Dashboards will back off until they
get the connection again and no data updates will be lost.

All,
Included as part of today's successful launch of the SpaceX Dragon vehicle
to ISS is an ARISS Ericsson 2 meter VHF radio. This radio will replace the
Ericsson radio that failed a few months ago. The VHF radio is used for
school group contacts and amateur packet radio in the Columbus module. Once
the Dragon vehicle is berthed to ISS, the Ericsson will be unstowed and, at
some point, installed in Columbus, replacing the UHF radio that is now
supporting APRS packet and some school contacts.
Our thanks to SpaceX on an outstanding and historic flight from Kennedy
Space Center's Launch Pad 39A, where many Space Shuttle missions and nearly
all the Apollo moon missions were launched. We also would like to thank our
ARISS benefactors-NASA and CASIS, the Center for the Advancement of Science
in Space. And, of course, our amateur radio long-time sponsors-our national
amateur radio organizations around the world, including the American Radio
Relay League (ARRL) in the US, and our international AMSAT organizations,
including AMSAT-NA.
Before closing, I want to let you know that ARISS is making great progress
on the development of the new interoperable radio system that we hope to use
to replace our aging radio infrastructure in the Columbus module and the
Service module. The hard (and expensive) part of this effort is just
beginning, with testing and human certification on the horizon. We thank
all that have donated to the cause thus far. We hope you continue to help
ARISS move forward through your support, including your volunteer time and
talent and, of course, financial contributions through the AMSAT web site
donate button.
73 es Ad Astra!

Hi All,
The post-launch TLEs for NAYIF-1 are starting to become out-of date.
We have produced a new set of unofficial TLEs that take into account
the new AOS / TCA / LOS timings.
Please however note that the post-launch TLEs do not contain the
correct constants to make this TLE reliable in the long run.
The only object that comes close in the recent TLEs from JSpOC is the
2017-008F object, but note that we are still missing a lot of objects.
They are working round the clock to map and catalog all remaining
objects, but 104 satellites presents a challenge.
We are in contact with JSpOC about this and are doing our best to help
them match up objects.
For now, the unofficial ones are:
NAYIF-corrected
1 17003U 17002A 17046.17714120 0.00000000 00000-0 00000-0 0 9994
2 17003 97.5521 107.5843 0004848 278.6481 296.8511 15.21991390 02
and
2017-008F-corrected
1 17004U 17008F 17050.08273148 .00155491 00000-0 65272-2 0 9998
2 17004 97.5078 111.7095 0000538 25.3680 334.7132 15.22769132 566
And we welcome any observations with regard to which one you used and
how much it was off.
I would think the 2017-008F variant will work better in the long run,
but we will have to see.

Weather is nice,
Time to put up antennas.
Now I know most like to go CP, But I'm on a limited budget. So it will
need to be a traditional linearly polarity yagi,
Of course I can mount them vertically or horizontally polarized.
And if it was just one band, is there ny preference to vert or horiz?
I don't see any, except from the man made noise issue when on low
elevations.
is there any best polarity?
I'm planning on a side by side 2 meter and 70 cm set up
2 meter vertically polarized on one end of a cros boom, and the same on
the other side but 70 cm.
This way I can get away with using a metal cross boom.
Thoughts?
