Venera 7 soft landed, sort of, chute failed and it fell over, on Venus. The
Russians never sent a spacecraft to Mercury, that I can find a reference to.
The US Mariner 10 did a flyby in 1974 but as far as I can tell Messenger
will be the first to land, or crash, on Mercury.

Hello all; our F6KBR radio-club is almost ready to be active very soon via
satellites with Yaesu FT847 rig but
we have a big problem: no power output on SAT position. Everything else is
OK, any mode...
We tried full Reset (menu #39) but still same problem.
Thanks for any help.

I bought my '847 second-hand and it was in pretty rough shape when I
got it. I had problems with how the output power was displayed, but,
after fiddling with it for several weeks, I sent it away and had it
re-aligned.
It seemed to have solved the problem.

Are these chit-chatters taking up time? Or possibly someone who does not

No. These people hear the downlink. This was a pileup situation for a
rare grid. Everyone was just too impatient to let the QSO complete
before calling. I was clearly called by the DX, and when I attempted
to give my report, I was crushed by another station calling. Most of
it did get through, in pieces.
Could have used some more juice to make 100% sure that QSO was complete!
There are a few of us who will just have to wait and see if we did get
in the log.

Listened to any HF pileups recently? The same thing constantly happens

Maybe we should have considered making Fox-1 dual frequency, so the DX
could work split and you would hear the full exchange from his end? :-)

Next one! Though that wasn't the issue here. No one was stepping on
him, just those trying to respond.
I really didn't mean to start the FM satellite debate here as there
are obviously pros and cons and it's good to have both FM and linear
transponders available for voice communications. I believe that 80% of
the problems on SO-50 are caused by people who cannot hear (and Fox
should do a great job reducing that problem). This pass tonight
brought out some of that other 20% and I just felt like venting :)

I like it that way . Its like contesting . Takes practice and skill to
be able to retain call signs and be able to run with the pile up . That
actually lost of fun . Its almost like been on the other side of
DXpedition .

Subject: [amsat-bb] What preamp to use for SO-50 and Arrow II antenna?

Since a lot of people are talking about SO-50 right now, let me ask a
question:
I did try to work SO-50 once when all I had ever worked before was
SO-35, UO-14 and AO-27 and I was horrified by how hard it was to hear
and track.
I found a thread on qrz.com where they said it's very helpful to use a
preamp for SO-50 since it's so low power, even with the short runs of
coax required for an Arrow II satellite antenna. I know almost nothing
about preamps. What's the deal? Do they need power to work
(active/passive?). What do you recommend?

I use a High Sierra Microwave LNAA432 preamp powered by a 11.1v LiPo
battery pack (AAs or AAAs work fine too). I can work SO-50 down to the
horizon with the Arrow Antenna if I have a clear shot. I lost at about
a degree on the pass earlier. It's usually S1-2 below a couple of
degrees, S7 above 10 degrees, and my FT-817 shows S+ above 30 degrees
or so.
You have to be careful not to transmit into a receive only preamp like
this. I use two FT-817s, one for receive and one for transmit, so this
is not a problem for me, but if you use a single radio, you would need
to be sure that the preamp is between the 70cm antenna connection and
the diplexer so you don't fry it.
