Well, it's a Scottish satellite and I found this reference on Wikipedia:
"Midori is known in Scotland for being mentioned in the comedy Still
Game, in which the character "Big Innes" has violent reactions
whenever he drinks the liquor. {Series 3, Episode 4}"
http://en.wikipedia.org/wiki/Midori_(liqueur)
Perhaps there's a better explanation!

I heard lots of new calls on SO-50 today and I really wanted to give them a
shout back and say welcome.
Unfortunately, that's about all I heard was a bunch of folks throwing their
call sign out.
Is there some "transmit only" mode that I'm not aware of? ;-)
On a more serious note, try to hear the downlink first before transmitting.
It reduces QRM and greatly increases your chances of making a QSO!

Also heard over the past few days on SO-50:
-Whistling
-"1, 2, 3, 4, 5, 6, 7, 8, 9, 10"
-"CQ satellite"
-"November"
You are definitely correct about the primary cause - people need to
put some effort into optimizing their receive setup as SO-50 has a
weak downlink signal. I was on a 10 degree max eastern pass of SO-50
(mostly over the Atlantic Ocean) around 1400Z this morning and had a
nice 4 minute chat with KG4JPL. Signals were S9+20 on my meter at 10
degrees. I am using an Arrow II 146/437-10BP, two FT-817s, and a High
Sierra Microwave LNAA432 preamp.
Here are a few tips:
-If it's the middle of the day or the evening and the pass is covering
most of the United States, there is someone on. Definitely wait to
hear it before transmitting. Only the night owl passes are devoid of
activity.
-Be sure you can adjust polarity. I've seen SO-50 signals go from
inaudible to S9 with a simple twist of the Arrow/Elk.
-Use good quality coax (I use LMR-240UF at the moment) and the
shortest run you can use.
-Operate full-duplex. Baofengs are cheap and have adequate sensitivity
to receive SO-50, get one to use as your receive radio if you're
trying to use a dual band HT without full-duplex capability. You might
even mount the receive radio directly to your antenna if you are using
an Arrow to eliminate coax losses.
-Listen to what's going on. If there's a QSO in progress, wait until
it's complete. If a station calls someone else, don't call them unless
the station called is obviously not responding. If there's a rare grid
or other rarely heard entity on the air, let those who need the grid
work that station, don't try to make other QSOs. If you key up and
have clearly lost the battle with another station, unkey.
-Throwing out your callsign once in a pass is OK, but it's better to
call specific stations.
The good news for FM satellite fans: EO-80 and the Fox-1 series are
coming! They will be much easier to hear with nice, loud 2m downlinks!
EO-80 is even capable of putting out 2 watts
(http://www.amsat-f.org/site/spip.php?article82) which would make it a
whopping 20 dB louder than SO-50, though it probably won't (and
shouldn't) be set to 2 watts output very often.

Glenn,
You are probably right, though I do think there are a few subscribers
out there that could use a reminder.
Also, the BB archives do show up in web searches, so someone searching
for SO-50 might come across this thread and learn from it.

I have avoided reporting from the European side of working SO-50 for a
while, but this afternoon I heard multiple good QSO's and I could
understand at least one callsign (M0SAT). I tried answering that callsign
2 times but no luck.
It was as busy as could be expected on a Sunday afternoon, but to me it
sounded like everyone was acting fine and those who got across had nice and
short QSOs (callsigns, signal, location).
> On a more serious note, try to hear the downlink first before

QSO!
You could miss your answer, the SO-50 downlink shift seems to me at the
moment bigger than the input width of a normal FM amateur receiver. If I
let gpredict do all the tuning from the specified downlink frequency I hear
nothing. Tune around a bit and I find it and it's busy.
I just noted
http://www.pe0sat.vgnet.nl/satellite/amateur-radio-satellites/so-50/
suggests not correcting for doppler shift on the 2M uplink. Any opinions on
that?

I can offer a better explanation ;)
It's the daughter of Steve Greenland, the UKube-1 systems engineer. He got
to pick the default CW beacon and the AX.25 TO Address when ordering the
radio, and picked his daughters name.
Midori means green in Japanese If I understand it correctly, which makes it
a nice name in combination with her last name Greenland.

periodically, in the ARRL Audio News,?where I have a segment in each week, I
try to give some operating tips. especially, if you cannot hear the
satellite, do not transmit as you will not hear those coming back to you.
maybe it is time to run it again. will see if I air it next Thursday if it
helps heal the problem.

Content-Type: text/plain; charset="us-ascii"; format=flowed
Several years ago I started posting grid maps on my
website so that grid chasers and grid expeditioners
could get an idea of what was needed by active satellite
operators. However, some of these maps have not been
updated in quite a while. And there are many new grid
chasers that have not submitted their maps for posting.
If you have a map that is currently posted and has not
been updated recently please send me an updated map(s)
or just send me a text file of the grids you have confirmed,
one 4 character grid square per line And another text file
of grids you have worked but are not yet confirmed using
the same format of one grid per line. I will generate the
maps from these files and you can download and print the
resulting map that will be posted.
If you have never submitted a map, please consider doing so.
Knowing who has what is very helpful to potential grid
expeditioners and it is a nice way to keep track of what you
need and where that grid is located with respect to grids
you already have. It's a lot easier for someone in a grid
adjacent to one you need to go there compared to someone who
might live hundreds of miles away doing the same. If you
send me your grid lists as specified above, I will generate
the maps for you.
Here's a list maps on my website and the date they were updated:

Good evening,
I have been on a few evening passes of AO-73 lately and have found
little to no activity. With the loss of VO-52, AO-73 now carries our
easiest to hear linear transponder. I will be on the 03:30Z pass over
the United States that covers much of the United States if anyone
cares to join me. I will be calling CQ at around 145.965 MHz.
The transponder will shut off just after 03:37:15 when it enters sunlight.
73,

Worked W5PFG and heard one or two others tuning around trying to find
themselves. I think someone came back to me right as the satellite
went behind my building and probably seconds before the transponder
turned off. Maybe next time!

Doppler shift at 2 meters is only about 3 kHz, well within the satellite
receiver's passband. Doppler correction on the uplink really is not needed.
