I still can't hear SO-50. I've checked out the receiving radio and it works
just fine. Has anyone ever had a problem with the UHF portion of an Arrow
antenna going bad? Loose connector?

I am on the Space Track website and cannot find any Keps for either PSAT or
BricSat. Where are you guys getting the Keps?
I have used all these designations.
PSAT (NO 84) = 90720 = ULTRASat 1 = 40654 = 2015-025D
BRICSat (NO 83) = 90729 = ULTRASat 10 = 40655 = 2015-025E
I find them but the Keps are blank.
I've been using Space Track for all my Sat Keps and this is the first time I
have had problems.

I took a direct hit. It disintegrated my 2m/70cm vertical. It was 20 foot
long. Now it is in 5 pieces in various length and the neighbor's lawn has
many piece of the radome. The tower is grounded with three grounding rods
that are connected to the service entry point on the garage. That saved 6
different radio from any damage. It took out a power supply that wasn't even
connected to the antenna that took the hit. I have polyphaser lighting
protection on all antennas. It has been up for 20 years and this is the
first major damage.

Number one on the list is a good tower ground bonded to the single point
service entrance ground at the house.
MIL-HDBK-419 addresses this very well.
When this is followed, you will have very minimum problems, unless, you take
a direct strike.
This can be minimized with static dissipators.
When was the last time you saw a FAA communications tower that took a hit
with any damaged equipment??

How about testing with your base radio, local repeater, another hand held,

Hi Steve!
Could you describe your antenna setup? Are you using the Arrow
Antennas 10W diplexer with your antenna? Have you tried running
coax directly from the 70cm feedpoint on the antenna to your radio,
and just try listening to SO-50? Have you put another diplexer
between your radio and the 70cm feedpoint? What type and length
of coax are you using?
Paul N8HM had previously asked if you could explain your setup a
little better. I didn't see a response to that post. If you are using the
Arrow Antennas diplexer, it is possible that something has gone
wrong with it. That happened to me with my Arrow Yagi several years
ago, where I ended up replacing the small diplexer with another one
(I think it was a Diamond diplexer, but others from Comet, Yaesu,
MFJ, and other brands could also be used). The Arrow diplexer is
not very sturdy, and some unintentional rough handling could cause
what you are describing - if you're using that with your antenna.
73!

Sounds like you have done your homework.
I wish more would do the same.
I did lightning damage mitigation in a previous job.
I had some professionals tell me I did not know what I was doing.
After the third direct hit to a commercial tower and the replacement
of all strobes the tower took no more damage causing hits.
Sometime later my boss directed me to return to the site and report
on my findings.
All of the recommendation, that I was told by the professionals that
I did not know what I was talking about, were implemented.
These included an aero spike, additional grounding and bonding of
grounds to existing tower and structure.
If you were to add static dissipators to your tower, you might be
able to dissipate the energy before it reached strike potential.

When you make your connection to your driven ground at the base of your
tower, make all your ground wires are as straight and as short as possible.
Lightning considers any 90 degree bends in the grounding wire (made to make
the installation look neat) as a high impedance in the path to ground.
Lightning may find a another way with less impedance that you do not want it
to follow. In my 37 years with a utility company, I have found that the
straighter and shorter the ground wire the better. I have seen a lot of very
expensive equipment thrown into the trash can because of ground wires with
lots of bends or because they were unnecessarily long.

The latest AMSAT Bulletin Vol. 38 No. 3 was great.
Quite a number of interesting articles. I found the CNCTRK article by
KI4SBL particularly interesting. The modular, metal construction seems like
a really good idea. Bob is very good on returning emails so let him know if
you have any questions about his interesting system.
In addition to CNCTRK there are a number of other portable rotors that have
been around for a while (satnnogs, WRAPS and
http://www.mobypicture.com/user/MeltdownCore/view/18165109 to name a few).
Has anyone built and used any of these relatively new lightweight portable
rotors. If you have any first hand experience with one or know of any
others please let me know direct and/or on the board.
tnx & 73 W9KE Tom Doyle

Message-ID: <6f46076fd3ddb062d3391f1c306ad20c@xxxx.xxxxx.xxx>
Content-Type: text/plain; charset=UTF-8
We need more Tracking Satgates in the eastern USA:
During the last pass Solidly over Eastern USA and dozens of packets and
many users, only two packets made it to the APRS-IS. So there seems to be
a paucity of Oscar class SatGates at the moment.. Of course tracking and
gain antennas are not needed for SatGates for the ISS, but are essential
for PSAT.
So if anyone in the USA has rotors and wants to exercise them and put a
little wear and tear on them for the next week or so, please feel free to
come on line.
We are trying to get PSAT properly set up for its attitude control and for
it to know where it is, and we need more data for a while.
We are getting solid data horizon to horizon over Europe, but very little
over the USA.
I completely understand the usual need not to keep rotors running for
routine. That is why we want to develop the Omni Satgates. But until we
get enough of them on line, we welcome more conventional tracking SatGates
for a while.
Thanks
Bob, Wb4APR

There was a NO-84 / ISS double hop opportunity this evening between
00:55-01:05utc.
I was able to send packets both directions, but did not see a double
hop. Both spacecraft were in view of each other as well as an i-Gate.
There is always next time.

Id only try via ISS first (it has 10 times more power).
Also, do not use generic ARISS,ARISS double hop, since if they both hear
it (likely) then they will both TX at the same time and not hear the other
one.
So use RS0ISS,PSAT.
BUT, I have a strong suspicion that PSAT does not digi via PSAT! (ARGH!)
Apparently the TinyTrack-4 of which PSAT is built, has a separate command
MYDIGI and it defaults to OFF!
We may have missed that in programming it. The few times I tried "VIA
PSAT" I was unsuccessful, but then I have so many other commands to send,
that I have not dwelled on it.
If anyone can confirm that they can digi via the PSAT call itself, let us
know.
If it does not work, then try VIA RS0ISS,APRSAT and it should recognize
the APRSAT alias.
Bob
