Hello Adrian,
ompletely agree about the rovers and I had excluded manual tuning operators
like rovers in my question.? I have worked a few and do my best to keep up
manually.? However the main focus of my post was to understand the drift
when both stations were automated.?

Umesh,
One other thing to consider that I have not heard anybody mention so far,?
most rovers will be using either a fixed uplink or a fix downlink? depending
on the satellite and correct for the higher frequency manually per the "One
True Rule".? Many rovers pre-announce their frequencies. In SatPC you can go
to the Mode menu and set which frequency you want Doppler corrected the
uplink or the downlink only, instead of both.
As a roving operator there is often a challenge. I typically announce my
fixed frequency via Twitter or AMSAT BB and find myself chasing operators
who are running full doppler correction during TCA. Then I have to fiddle to
get back on frequency.?? Just something to think about to make life easier
for the rovers working the pile ups while minimizing the need to retune and
maintain a high response rate.
As was previously mentioned use the RIT too.

Good Morning All,
I'd like to understand something that seems to be happening with SSB birds.?
I realize that they are two kinds of operators - one that has a computer
controlled station and one that tunes manually, and I respect both types.?
The following observation is about two computer controlled stations working
via a SSB satellite -?
?
(a) My station is computer controlled (SatPC32 or HRD) and can hear myself
on the downlink throughout the pass.? I can also go up or down the pass band
and still hear myself without needing to retune the uplink.?? It is pretty
rock solid, almost like HF operation.?
?
(b) Sometimes I hear a station calling CQ and it remains on the same
frequency during successive CQs, so I'm guessing their station is also
computer controlled.? I can tune in and stay on their calling frequency.?
?
(c) However, when I can respond, it seems they have to tune their downlink a
bit to hear me well.? So when they come back to my response, they are a bit
off-frequency (about 300Hz) and sound like Mickey Mouse, until I retune the
downlink to hear them well again.? This keeps happening throughout the QSO.?
?
(d) This "drifting" happens only with some stations calling CQ and not
everyone.
?
Considering both stations are computer controlled at each end, I'm trying to
understand if I'm doing anything wrong/incorrect.? Learning to operate SSB
sats has been humbling as well as exciting, I'd appreciate any pointers for
this situation. Thanks in advance.?

Hi,
I completed the survey a couple of days back and in retrospect I had
one other comment to make about the survey itself.
In the section asking what bands or frequencies of operation I'd
used or was active on the last option was "not interested". I would
have liked to have had another option "interested but not equipped" or
something.
Lastly I wanted to say that I appreciate the opportunity to take the
survey and I am curious about whether the survey results will influence
the design team.

Before this goes on ebay, I have the following?
FT-736R with MD-1 Desk Mic, 1.2 and 220 modules, Keyer, CTCSS Tone board.
Internal supply still works and comes with AC power cord.
Only thing missing is the little door that covers the A/V jacks for the 1.2
module.
Excellent cosmetic shape and everything works perfectly! Recent "basic"
tune up. (Power, ALC, RX and Freq check)
No manuals. No original box.
$1100 + $75 shipping and insurance. (It will be boxed very well and sent
Fedex) Paypal preferred.
Local pickup if you want in Sacramento area.
Email me direct if you want photos.
I'm pretty sure there aren't any on here, but message to scammers/parts
swappers?..Every board, module and option plus serial numbers have been
logged, photographed and has hidden marks with IR ink so don't even think
about it!

Great job
Im going to contradict myself. Don?t use the RIT...(then maybe use the RIT)
Hopefully your RIT is off when you adjust your uplink in Satpc32 to line up
and match the pitch of your voice.
If I find that I have tuned to someone calling CQ or in QSO - when i call
them ??> if they move, yet I can understand, I will accept the pitch
difference and NOT touch the main tuning dial for that round of the QSO so
things stay constant for the other station
If we go another QSO round and things are still about the same amount of
frequency offset, I?ll just compensate slightly with my RIT.
If you?re within 300hz I?d say you?re doing well, and touching up with RIT
is well within reason.
Like drew suggests- carry on.
Thanks,
Mike

Good morning all,
One thing that I have noticed with trying to tune in a qso or even tune
myself so that I can even find myself on the downlink is not easy some
days. If I use the rit then sometimes I loose the other party on there or
they can not tune up to me very well. One thing that I have noticed
thinking about this if I turn the rit on and use that then turn the RIT off
and then try to tune the xmit freq I see that the XIT is also changed to
the same amount as the RIT control.
So having found this and trying to work with SatPC32 trying to tune using
the cat control section I am not having very good luck somedays getting
things tuned up. I don't try to do these at the same time, I work with one
or the other, just have not found a good happy medium yet for tuning in the
different ones.
Now I am thinking that I might want to reset all back to square one with
the radio again and see what happens with the RIT and XIT if they track
together or not if I do a full reset of the radio.
The rig is the TS2000X, it took sometime getting it to work with Satpc32
and now I know where I made the mistake on the basic setup so that I can
get things to a working point with the software for tracking again. Just
seeing that the RIT control and the XIT track together even thou they are
not on together that I know of when I try to work things.
This I only found this week. So any thoughts on this?
Thank you.
Jim

Hello Bob,
I too am interested in VHF/UHF amplifier suggestions, but for a FT-817ND
(with TCXO-9).
I am not sure about Mirage now that it is an MFJ brand. A lot of online
reviews pre-date that transition. I am somewhat interested in the RM Italy
products sold at DX Engineering.
On a related subject, I note the ARRL lab test of the FT-818 does not
recommend amplifier use, which is disappointing as I suppose that reflects
on the quality of it?s output signal.
I also hope there will be an IC-9700 in my future!

I forgot to mention that I have 65 feet of 9913F between my
antennas/rotator and the radio hence the need for the amplifier. I do
understand that if I was using an Arrow antenna (as I have in the past)
with my Icom Z1A, I'd have no problem working the satellites.
Still, no replies?

I want to use it with my antennas while I no-so-patiently wait for the
