In a perfect world, everyone would be using full doppler control via
computer. As we can see from this discussion, it's not a perfect world.
During the time that I had the equipment to operate the linear birds I
found hooking up in a QSO with another station who was using full
doppler tuning by computer also was quite an enjoyable experience. Even
"reading the mail" while two other gents were in contact on full doppler
was fun. Not so if I came upon a station who was using manual tuning
while I was trying to let my computer do the work. I had to chase him
all over the passband and often lost stations completely that way. I
didn't fare much better with manual tuning. I guess I never really
learned it like some of the "old hands" have.
When I can finally afford the V/U unit for my new Flex and get back on
linear birds it would be my hope that everyone who was in a base station
setup would be using full doppler control via computer. It baffles me
why anyone wouldn't, it makes life so much easier.
I do understand why portable stations like Tim would not be using full
doppler and I have no problem with that. I guess I just need to learn
how to manually tune in that situation.

so this is my lack of sat operating experience talking here, but just
looking at the math it seems that it would be difficult for two stations
with different velocity vectors to the satellite to communicate without at
least one of them adjusting both TX and RX. I need to try this for myself I
guess.

The rate of change of Doppler shift is at a maximum at this point,
which means you're moving the VFO knob fastest. It's like when you
hear a passing car, the change of pitch happens as the car is passing you.
Yes, the amount of Doppler shift might be zero then the satellite is
tangential, but the rate of change (in Hz/second) is maximum.

I agree, Full Dopller Tuning is the best way to go, if you have the
gear. I'm looking forward to giving it a go, when I get my satellite
antennas up. The radio and CAT interface are in position.

I have had quite a bit of success with manual tuning on the SSB
birds. It does require a lot of attention, especially on V/U and
U/V. On mode A, it's fairly straightforward, though adjusting the
uplink on a radio that doesn't allow tuning on transmit is
tricky! One has to break their over into short segments of a few
seconds long and make the uplink adjustment in steps. :)
On V/U, I was using an FT-847 at a hamfest, which was easier,
provided I focused on keeping up with the Doppler. :D

In my past, it was simply because I didn't have the right
radio(s). Now I have an FT-736R, and the first accessory I bought
for it was a CAT cable! :) I can even dedicate a computer to the job.

One problem with the Yaesu 736R is that when the rig is under computer
control you can't grab the tuning knob and hunt around the passband for
someone to talk to. "Tuning" directed by computer is agonizingly slow and
tedious, taking about a second per change, so that's out. And since the
rig's frequency cannot be read by the computer, you can't hunt manually and
then lock things in on the computer. (I suppose I could re-write my CAT
client to allow me to visually read the frequency off the display and type
it in, but that would be tedious too...)
So, for me, SSB is full manual. FM is full computer. (and CW is wishful
thinking) Sometimes I'll use the computer to get my manual tuning started,
picking mid-passband to get the VFOs close. Then I disable the computer,
send a few dits to verify, flip to REV to lock the VFOs, and go manual from
there. If you run full manual often enough, it becomes second nature. I
used to be able to find myself on RS-10 in just a few seconds, anywhere in
the passband. But that was a REAL "EasySat".

That does make things a pain. It's a pity that the radio can't talk
back to the computer, which would have been a nice addition.

Well, I had no problems flying the RS birds manually, and I have done

The one TRUE method is do whatever it takes to make the QSO!
In reality I almost always wind up tuning both up and down links. I make
sure most of the adjusting is on the higher frequency.
I can't say I have ever slid into another QSO, but even if I do, it is just
an opportunity to speak with more friends I haven't met yet! I am usually
very hard pressed to find more than one or two QSOs in the passband anyway.
As I mentioned before I have found computer tuning to work just fine on the
FM birds (no slop involved), but always find myself fighting against the
computer aided linear tuning. I tune the station in perfectly and then the
computer moves me off frequency. I tune the station in again and the
computer moves me off frequency again. I turn the computer tuning off and
make the QSO.
I would be game for some pointers as I would like to at least claim I have
made this work once.

Folks I've been patiently silent reading this d?j? vu annual discussion and
I'm getting a brain crap.
- comments that tuning the highest frequency is the "One True Method"
Yikes! Why is that? So you can leap frog down the pass band and eventually
stomp all over a QSO where folks are tuning both TX and RX to maintain a
single constant frequency at the satellite?
I've read the " Doppler tends to move more quickly near mid-pass than the
computer and software routinely seem able to keep up". Mid pass is when the
sat is moving most tangentially to you at which point Doppler shift is nil.
I've read statements from many taking pride in their lack of use of current
technology.
I've read that working tight SSB sats is easier than the wide band FM where
the satellite is very forgiving of your sloppy tuning.
I've read advise to someone using an FT 736r that your shouldn't tune the RX
and ignore the use of the NOR/REV feature, again so you can eventually stomp
on other QSO's as you slide down the pass band.
Have I just been transported into a Bizarro World?

The true pity is that the rig IS physically capable of talking to the
computer, but the only thing it knows how to say is what the status of the
Squelch is (open/closed), and what the S-meter is reading. It should be a
trivial matter of software to report other things, but apparently the only
use the CAT designers considered was remote (computer-driven) scanning and
monitoring.

Message-ID: <20100601195824.S8TOU.597402.imail@xxxxxxxxxxx>
Content-Type: text/plain; charset=utf-8
Hello all, I'm new to the boards here and was browsing through and saw a
post a few weeks ago about using an Alt az Telescope mount as an antenna
rotor.
I didn't see a response so I'll add my .0661 Malaysan Ringgits based on my
experience as an Amateur Astronomer.
First I have to presume that the OP already has the mount in question as a
purpose made rotor could be had for a lot less money.
First I'd think wind load on a typical antenna wouldn't be that much, but I
would mount the antenna with it's center of gravity as close as possible to
the elevation axis. Since a telescope would be mounted with its CG ON the
Elevation axis, you'd want to keep the Antennas CG as close as possible to
minimize and torque loads on the gears. I'd also use a sturdy dovetail
mount, though that being said it looks like the mount in question is more
than capable of handling the weight.
Also make sure that the antenna will clear all aprt of the mount though it's
entire range travel.
As for tracking, I'm not sure if it will track fast enough. I couldn't find
any specs in that regard. I know the Meade Autostar can accept Keplarian
elements and track sats. Quite frankly it looks like a pain to upload them
and I've never tried it, though I've been tempted.
Since I've gotten interested in working the birds (Still have yet to make a
QSO, Building an antenna and amassing the needed equipment), I've been
looking at my Orion EQ1 German mount as a possible rotor. It's a basic
Mount and I've figured if I mount the antenna with the beam paralell to the
Dec shaft, alI have to do is set the lattitude comlimentary to the Max
elevation (90 Deg - Max El) and point the RA shaft opposite the Max
Elevation Azimuth, it will track the path of the sat. It won't track using
the Clock drive, but I should be able to keep up using the slow motion
controls. That being said, substututing a faster motor shouldn't be too
difficult for a later project.
Hope this helps.
Now if someone could show me how to reply to thread on the archives......

In the event that anyone at Camsat sees this mail ...
It would have been nice with a SITREP - (situation report) - about the

here are a *LOT* of people 'wondering' ...
I summise it has something to do with the President of China visiting the
ground station and
Alan Kung being in the entourage ... but still, a SITREP would have been nice.
On behalf of the myriad of satellite operators in Europe I would apprecate
some word on

Thanks for your reply.
I'm using the TLE for object 36575 for tracking Negai*", too.

Myself here in the US, I have just been listening for it on each pass, like
yesterday, when I worked 3 passes on SSB/CW. Could be they are leaving it
on all the time, and only on a weekly basis, change the modes... my guess..
If that is the case, no need for a schedule, which for me, is preferred.

In the event that anyone at Camsat sees this mail ...
It would have been nice with a SITREP - (situation report) - about the
weekly schedule for HO-68.
here are a *LOT* of people 'wondering' ...
I summise it has something to do with the President of China visiting the
ground station and
Alan Kung being in the entourage ... but still, a SITREP would have been nice.
On behalf of the myriad of satellite operators in Europe I would apprecate
some word on
the current status of HO-68 ... at your convenience.
Thank you.
