Ouch, just checked the price list for the KU LNC
MKU LNC 23 TM ATV Converter mounted into water resistant case, in 2320 ...
2450 MHz, 1404 ? 1534 MHz IF 216,00 ?
That is before shipping. If I don't buy litter for the cat in the ham shack
this zone will soon become uninhabitable. That is before shipping from over
there.
Does anyone have options that are more reasonable for a LNC? I would really
like to do this project but was a stretch to get just the PCI tuner card.
If anyone has another option you may e-mail me off list. Not too technical
please, I have not used a soldering iron except to do wood burning for wood
crafts as a teenager. Will a US made universal work? In the end tho I would
like to produce a quality product.

During the first year, or so, with AO-7, I used horizontal polarization with
the 2-meter and 70-cm antennas elevated about 30-degrees. ?The 10-meter
antenna was a 2-element yagi horizontally mounted. ?Only the azimuth was
varied. ?Later I added an az-el rotor for the 2-meter and 70-cm antennas.
?However, the 30-degree elevation worked very well.

hello Ed...I have found that with AO-7 over the years...it depends... of
what I am not sure..be it satellite orientation, local issues, or simply
"propagation gods". There are times when switching between L & R on either
up or down link will improve reception. My current installation is currently
not wired for switching and defaults to RHCP for up and down. I do not
appear to have any issues with AO-7, I do plan to connect up the switching
simply because, it's there.
From: "edroth2006" <edroth2006@xxxxxxxxx.xxx>
Can someone tell me what type and polarization the antennas are that are
currently in use on the AO-7 satellite?
I've done many searches and cannot find this information anywhere I have
looked.

I am not sure if this grids are active or not since I have not have the
chance to work them yet, but I be portable and active on SO-50 only from
7/10/2013 till 7/15/2013. I be active on as many passes I can. If anyone
need this grids can contact me via email my information is good in QRZ.com.

I dug out some old books including OSCAR: The Ham Radio Satellites by Dave
Ingram, K4TWJ, and OSCAR Amateur Radio Satellites by Stratis Caramanolis,
and the AMSAT Journal from December 1974. All three agree that in the
Northern Hemisphere, AO-7 polarizations are as follows:
Mode B uplink and downlink RHCP
Mode A uplink LHCP
Mode A downlink linear
435.1 beacon LHCP
The turnstile is shared on both 2m and 70cm.
I hope this clears things up some.

Well, it was fun (and sometimes equally frustrating) while it lasted but
it didn't last long enough.
Had a good overhead pass of FO-29 tonight, but once that thing gets down
below 40 degrees pointing toward the U.S. the noise gets to be a real
PITA. I had on my best ears and some DSP but still couldn't get enough
out of the buzzing and whistling to make a complete contact with but two
stations. I hate that!
Special thanks to Hector CO6CBF who was always on to let me test my
doppler and get a signal report before the bird was AOS over the U.S.
So it goes. I guess it will be a year before I get down here again, so
I have some time and experience to put to use to see how I can make it
better.
Thanks to all who called, you made my days, just sorry I couldn't make
all of yours.

We have an urgent need for Ham Packet Ops on mountain tops in New
Hampshire, Mount Greylock, MA, Sams Point, NY, Clingmans Dome in the Smokie
Mountains and Roan Mountain NC.
This is a 4 hour event making our annual attempt at the Golden Packet, an
APRS packet message from Maine to Georgia along the Appalachian Mountain
Chain on Saturday 20 July.
All you need is an APRS radio that can digipeat (D72, D700, D710) and a
power source and antenna. (and Know how to operate it!) All of these sites
are ?drive up? except Sam?s point in New York. The attempt is from noon
to 4 PM. Remember, Tim, KA1YBS has to begin in the dark to climb a full
MILE straight up to get to the top of Mt Katahdin in Main and then get back
down before sunset. Hence, the 4 hour window.
This is our 4th annual attempt and last year we were successful except for
only one broken link in NH. Will you be available to help make history?
The Golden Packet was proposed back in the early 80?s. It has never been
claimed since the rise of the Internet that has eclipsed all DX packet
attempts. We will do this every year even beyond success. It is a good
test of emergency long distance packet techniques.
If you can activate one of the above 5 sites, please see detail links on
this page for each site and learn all you can:
http://aprs.org/at-golden-packet.html
Think of this as Packet Radio FIELD DAY! These 14 sites have been well
surveyed and we know the links will work, if everyone can get in place and
KNOW how to operate their radio.
Other secondary sites are also invited on Stone Mountain, GA, Lookout
Mountain TN, and Huntsville Mountain

FITSAT-1 was still transmitting over Texas (EL29) this morning. I first
heard the signal at 1209UTC (7/3/2013) . Signal was strong and stable.
I am using an IC-910 with M2 436CP30 antenna and Icom AG35 preamp.
Antenna is on a Yaesu Az/El rotator.

FITSAT-1 was heard over Texas (EL29) at 1344UTC (7/3/2013) Signal
strength was changing considerably and it seemed the time between CW
bursts was changing. Perhaps the signal strength changing simply caused
me to miss part of the transmission. Maybe the satellite is tumbling.
I updated my Keps but I have a feeling the numbers are changing and I
actually did not have my beam pointed perfectly. I am sure I looked
like a one-armed paper hanger while tuning everything on this pass. I
also forgot to turn on my recorder (or I simply ran out of hands) for
this pass. My next opportunity to hear FITSAT will be later today.

Yes, but it is all about risk. Generallly, 90% of all packet radio/TNC's
on the air are misconfigured in someway or another. It has been this way
for the last 40 years of packet..., and although they "work" some suffer
as much as 20 dB or more loss of weak signal performance (but no one
notices because it "works"). Most are just plug-n-play till it "works"
with no attention to levels, deviation, clipping, compression, skew,
balance, bandwidth, pre-and de-emphasis, etc.
When trying to do a one-time long-chain national test, the risk of a
single station not meeting 100% optimum settings and causing the whole
test to fail is just too high. The kenwoods may not be the perfect of any
of the above settings, but they are factory consistent and beyond the
owners abilty to screw up. And they are very sensitive to each other,
able to decode each other's packets down to only 3 bars (about -116 dBm)
where as some TNC's and Trackers must have 60 dB over S9 full scale dead
full quieting signals before they are decoded. Yet their owners claim
"the work"...

And said another way, These radios all use a flat passband and most all
TNC/Radio combos use pre and de-emphasis. I'm not saying one is better
than the other, but we must have consistency. Many Many dB of weak signal
performance is lost when one tries to talk to the other.
