Kevin, ? ?(et al)
Your write-up & explanation sounds very fair and proper as far as I'm
concerned. Its philosophy, in general, is
the same that I use. If I put out my Call and someone responds with my Call
and their Call, I'll repeat their Call
and usually my Grid Square. They will respond with some kind of
acknowledgement - QSL, Thanks, Roger, 73,
Good Luck, 10-4, etc. Then, someone else will jump in with their Call or
I'll announce mine and the sequence
will repeat itself. If I'm in a rare Grid and/or there's a pileup, I would
probably say QRZ or go back to a partial
Call that I heard to speed things up. This is all very similar to HF
Contesting while running a pileup.
On the Linear Satellites, it is pretty straightforward. I go a fair amount
away from the middle of the passband and
put out my Call. It is usually obvious when you hear a response since I'm
the only one there that a Station would
be calling. We have a normal exchange and carry on. However, on the FM
Satellites, it gets pretty chaotic at times
since Stations often transmit on top of each other for reasons I won't go
into here. In this case I need to hear my
Call and their Call to ensure they are really calling ME, otherwise I become
someone transmitting on top of some
other Station. Once I'm sure they are calling me, I'll respond with their
Call and my info. I'll roger that QSO quickly
and WAIT to see if I get another call. Then, I'll wait a little more to see
if other QSOs are going to take place and
I'll put my Call out again if nothing transpires. I always avoid
monopolizing an entire Pass. Sometimes, if I'm in a very
rare Grid, there will be a non-stop stream of callers that I'll have to deal
with. Unfortunately, with a single-channel bird,
that's just the way it is since there may not be another operation there for
quite a long time.
Trying to make a Log in real time on a Grid Expedition is nearly impossible
with only two hands and two feet. In my
case, I'm doing everything manual in every respect. Wait for AOS and hear
the Satellite and properly point the antenna
and adjust the polarization and hear myself on the downlink and put out a
call. Then, respond to the callers and tune the
receiver and constantly maximize the downlink signal by adjusting the
antenna azimuth, height and polarity. Continue
doing all of this until LOS. In the South, you also have to deal with Sun
and heat and sweat come down into your eyes
and your glasses sliding down your nose. In the North, you must deal with
the wind blowing over your tripod and little
black flies and mosquitoes biting you or crawling into your ears and nose.
Everywhere, there is always the chance that
Police or Security Guards or curious onlookers or property owners will try
to talk to you DURING a Pass or will park
their vehicle directly in front of your antenna!!
So, to avoid losing any QSOs during any/all of the confusion and
happenstances of the above, I use a small digital
recorder to make an audio record of each Pass. Later, I transcribe the
contacts into a spiral notebook as a permanent
record of my Grid Expeditions. If there is a question of whether a contact
was actually made, the info is maintained on
paper or I can re-listen to the captured audio. A recognizable reply from a
Station-in-question's Call is good enough
for me and I'll always give the benefit of the doubt in favor of a QSL.
Faking a contact is only cheating one's self out
of the real satisfaction of making a valid QSO with a needed Station. ?Amen.

Subject: [amsat-bb] QSO Protocol
As far as valid QSOs for ARRL awards are concerned (DXCC/VUCC/WAS), they
simply state a 'contact' must be made. But no where do they ever define what
a contact consists of. They leave this definition up to the award applicant
and the stations that he/she contacts. When asked, I have always explained a
contact as, "I called you and you knew it was me, you answered and I knew it
was you..." In short, as long as we both understand that we 'contacted' each
other, then it's a contact.
My point is, there is no specified rule that says a grid square or any other
piece of information is exchanged. There is actually no rule that says the
CALLSIGN must be EXCHANGED. A contact exists when the two parties involved
in the communication agree that the contact happened... whether they
exchange a 'QSL' on air, via e-mail, LotW or by USPS mail, if both parties
agree that it took place... then it took place. The requirement for any
more, is to saddle the participants with a burden to overcome the
non-natural hindrances that can occur with high volume traffic over man made
devices... i.e. satellites. If EME or meteor scatter operators want to place
certain burdens upon themselves to ensure that their imaginations, tricks of
the senses, or natural phenomena did not insert a bit of faux communication
that did not actually take place, that is their perogative. BUT, why should
one penalize a station and say that a contact did not take place simply
because some guy with 50 w
atts and crap for a receiver decided to say, "Halllo! One, two, three,
haaaalo!" over top of Jeeves while he was uttering his grid square. Further,
since satellite passes are a time limited resource, why should we take away
precious airtime from others by forcing a repeat of a piece of information
that we likely already know, and at the very least can easily look up
online, etc.
Simply put... if I'm in a rare grid square working lots of stations on a
frenzied pass and I hear a voice I recognize saying his/her callsign while
obviously calling me, but someone keys on top of him in the middle of saying
his callsign, is it really necessary for me to say, "Who is the Hotel Mike?"
when I KNOW who it is? OR worse, stop to take the time to ask, 'What's your
grid again, Paul?' - Paul knew it was me, I knew it was Paul, I'm simply
going to say, "In the log, Paul," and call the next station.
Common sense and basic trust in personal integrity goes a long way towards
making life simpler and more enjoyable.... QSL?? 73!? N4UFO, EM95, over.

Looking for a program called SatEvo by Alan Pickup which is used to predict
decay rates.
All my Google/Bing searches come up with links to:
www.wingar.demon.co.uk/satevo
or some variation, which is a dead link.
Any current source? I have seen relatively recent postings of output from
the program.

I recently purchased an Advanced Receiver Research 2M pre-amp to use when
operating on the LEO SSB satellites. I purchased the SP144VDG (24 db gain,
<1 NF). They don't offer the lower gain, higher noise figure 2M pre-amps
anymore.
I tried setting it up this weekend and when the pre-amp is on and I'm
transmitting on the 70cm band, I'm getting a lot of audio distortion. When
I tried this during a pass, my audio on 2M was barely readable because it
was so distorted, but with the pre-amp off, I sounded fine.
I'm currently using a 2m/70cm Arrow antenna mounted on a portable Yaesu
G5500 Az/El setup. When I spoke with ARR, they suggested it was a
desensitizing situation and it may be due to the 2M and 70CM antennas being
so close to one another.
Can anyone help or suggest some things I could try to eliminate this
situation? Separate antennas? Some kind of filter before the pre-amp?
The pre-amp sounds great when turned on, but right now it can't be used
when I'm transmitting at the same time on 70cm, which doesn't help.
Thanks,
Dave N2TEB

It sounds like the active devices in your 2m LNA is getting crushed by
the output of the 70cm transmitter.
You could try "A Simple Desense Filter for Mode-J Satellites" in
reverse: you want to put the preamp and radio on the 2m side and leave
the 70cm side unconnected.

HFSAT Duplexer design welcome,
If anyone wants to take a shot at designing an HF Duplexer so that the
single 29 MHz dipole can also be shared with the 21 MHz uplink, here is the
schematic (maybe): http://aprs.org/hfsat/HF-duplexer-a.png
It is my guess at how to build a trap and pass band on each side of the
duplexer. But then I am not an RF designer at that level.
The overall web page for HFSAT is: http://aprs.org/hfsat.html

Hi Zach - I checked out that article and to my surprise I had a Comet
CF-416 duplexer sitting in my box of radio parts down in the basement. I
did a quick test of the setup down in my basement and was able to easily
reproduce the desensitization scenario. Then I changed the wiring and ran
from the antenna to the duplexer to the pre-amp to the radio. No more
desensitization!
I will fully test this out the next time I set up my portable satellite
station - hopefully this upcoming weekend.
Thanks to all of those that replied to me - I have other ideas I can
experiment with as well based on your emails, but I'll start with this one
and see if it works for me.
73, Dave

All,
As a result of further cross-tagging, the TLE set for Pratham is now
published under object 41783, 2016-059A.
AlSat 1N is still object 41789, 2016-059G.
73,
