I think Patrick raises an important point here. The FM sats are a very
good entry point into satellite operation.
I got into satellites as a result of seeing just how easy it was to make
contacts on AO-51 with a radio shack HTX-242 and an FT-817 that I
already owned. Since I have been bitten by the satellite bug, I've gone
out an bought an FT-847 and pre-amps, and I will hopefully be putting up
a better antenna array soon to help with linear satellites.
If it hadn't been for AO-51 and its "Easy Sat" reputation, (helped along
by K7AGE's videos on YouTube), I probably would have never gotten
started and kept on thinking satellite operation was "too hard".

I'm looking to add an amp on VHF with an Icom 910 to do some weak signal
work on the VHF bands. In addition, it may help my 23cm uplink on
satellites. Since the 910 doesn't have an amp relay like most HF rigs, does
anyone have suggestions on the best way to wire. It appears that I have to
use the PTT/Ground in the microphone. Any suggestions or experience with
this? Can e-mail me off board too at almetco (at) Comcast (dot) net.

The manual is poorly written with regards to this feature, but Pin 3 on the
ACC jack grounds on TX. I break out all the pins to a terminal strip, then
use this to key my KJ6KO L amplifier.

Hello
With all the good/bad comments about the K5D satellite efforts I believe these
and future efforts should be encouraged.? As I remember AO-40 (sobsob) was on
several dxpeditions.? I believe there was a shipable "kit" of sorts for those
efforts.? Not only should we use FM sats but our? other LEO birds for these
endeavors.? The more exposure we get, the more exposure we get.? This equates
many good things for our niche of amateur radio.

You use the phonetics that work. If your call gets busted the same way on a
regular basis it is time to change things up. My call is kk0sd. When I say
kilo kilo zero sierra delta, the station always comes back k0sd when I say
kilowatt kilowatt zero sierra delta they get it right every time.

The NATO/ITU phonetics aren't perfect. The "DXer's" phonetics (mostly
place names) are a reasonable alternative, but only the two sets
should be used. When I'm working 'phone, when I've got it together, I
try to repeat back using the other set. And I hate Kilowatt, too- I
always hear that as "KW".

I am often guilty of not using the correct phonetics, but I do have a
reason. 95% of the time, if the other station has marginal reception,
they come back as VE5, not VA5. I think it's just the other ops' brain
filling in the blanks with what they expect to hear, so I will correct
as "Victor America 5" and it usually seems to solve that problem. I do
try to stick with the ITU phonetics 99% of the time though.

Having been on a few DX-peditions, I can't imagine the sense of failure
that
would go with running a DX-Net on a satellite, However, I nearly missed the
following great idea from Bruce.
Actually we can do split on AO-51. If anyone felt a DX-depition was
worth
the effort and resources, we just tell the DX to use one uplink channel and
the people replying to use the other. It would maximise QSO rate and even a
handheld with low audio would be Q5 without any interfering signals.

Very interesting Bob..... I had just sent this to a friend of mine to
look at before sending to the bb. It is basically the same thing.
However, taking checkins is too time consuming, this is a much easier plan.
When dx stations are working HF and they are operating split, they can
very easily move up and down the band to find a station that is in the
clear. Also, no one has a problem hearing them (except for the
occasional guy that forgets to hit split). However, when on the
satellite, you do not have the luxury of split operations on FM.

NA1SS, Mike in the ISS tried in vain to contact K5D earlier today. I
heard K5D quite clearly on ISS working a few stations; but it appears
they shut down the operation right at the time Mike was calling them.
This is only a guess in my part, that someone there must have looked
at the footprint and determined that no one else would be on the air
from stateside.
There were some stations down south calling them, and I asked them to
please wait since Mike was calling them; which they kindly did, but it
looks like Mike lost a great opportunity to work them. I can only
hope he was able to work them when I was no longer in the footprint,
but I doubt he was able to.

On the actual amateur satellite fleet AO-51 is the most controversial
satellite since the first day he was on the air. Some says it was the
poorest choice ever made by AMSAT-NA some other says it was a newbie sat but
both and many agree it is the "madness sat" making each and
every user mad at times.
There is the commander in chief who want to drill the troups
There is the humanist who pray to have some humanity
There is teacher who wants more teaching
There is the king of the grids who want this new one at any cost
There is the long rag chewer and his body always there on each and every full
pass
There is king of the QRP with his micro micro watt micro HT and his hair pin
duckie yelling in the middle of a brass section band
There is the QRP master who is still dreaming awake of an ideal and perfect
QRP world
There is the guiness certificate QSO number record chaser looking for his next
10000 plus one QSO just stepping over the QRP boring noise.
There is the former moon bouncer using his setup on the birds
There is the frustrating ones who blow wistle knock on some pass
There is the ultimate problems solvers who never succeed in solving anything.
And all of them on a SINGLE CHANNEL
There is me listening silently remembering that i was so lucky to operate on
a HEO called AO-40
There is all the others who believe that we will al ended up back to HF pretty
soon.

Thank you to those that replied !
>From the feedback I understand that;
- my TS2000X should be in FM mode, connected to the TNC via ACC2
(was indeed the case, thanks for confirming)
- my external TNC, the PK-96, should be able to decode GMSK 9k6
(indeed I can decode AO51's downlink)
So...: I will need to team up with someone else in my footprint
to see how the Cute digipeater (downlink) can be activated. At
this point I have not even heared it, so it can be my ERP
(antenna or RF pwr) or the way my PK-96 is generating GMSK 9k6
signals (vs. how Cute expects them).
Thanks so far, I'll certainly share it if I have more success !

Mike NA1SS just worked K5D at 1543z this morning. Mike came on about half-way
through the pass and began calling K5D on schedule, but K5D was not then on.
Mike was kind enough to come back and give out a few QSOs to myself and others
who were bold enough (rude enough?) to call him while he was waiting for K5D.
Gary at K5D finally came on and worked Mike just as I was losing the bird.
As others have noted, there really is some problem with the audio on the HT
that K5D is using, but he is copyable.
