RE: [amsat-bb] Yaesu 847 Doppler Control

["Chad Wasinger" <n0yk@xxxxxxxxxx>]

Brad,

First off, Glad to hear your getting on the satellites, you'll for sure like
it!

I'm not exactly sure how it does it, but I'm sure it takes in account your
location in relation to the satellites location at that time. The
DDE-interface is just a way for SuperControl to grab information from Nova
and be able to keep the Doppler accurate on the radio. I use this feature
mostly on the FM satellites, works very well, keeps it on the right
frequency the whole pass!!

So if you would like to do the Doppler control and use the SuperControl
program with the Yaesu 847, all you have to do is download the program which
you have a 30 day trial period and then do some configuring and your all
set! Also you need the null modem cable to allow the computer to communicate
with the radio. Since your already have Nova, then your all set after you
get the SuperControl, because you have to have both programs to make it
work.

If you need any more help with this, just let me know, I'm using and would
be glad to help out.


Good Luck,

Chad

I am new to the birds and am setting up a sat. station.  Should be up maybe
next weekend.

How does a program know how much to shift for Doppler changes?  Is it as
simple as knowing the birds orbit?

Your email confused a little.  Is DDE-interface a different program than
SuperControl?  I definitely want Doppler control.  I have already installed
Nova.

Hey John,

I personally like the SuperControl program by Peter Pfisterer
www.supercontrol.de. If offers a whole lot of other features besides Doppler
control.

Like:
Full duplex (two-way) crossband repeater with semi repeater-offset. The
FT-847 transceiver itself is only able to do one-way crossbanding.

Wave recording of qso's or other important signals. FT847-SuperControl(r)
has
the possibility to record signals either when the squelch has been opened or
on other selectable events. For this feature, a standard sound-card in the
computer is necessary. The recorded data will be saved automatically to a
special drawer and can be replayed at any time.

Spectrum scope of AF (Audio frequency).

ect..

And then the one I use all the time:

DDE-interface (Dynamic Data Exchange) to satellite-tracking programs
(NOVA(r),
Satscape(r) etc.) for Doppler-correction in satellite mode. The
Doppler-corrected frequency will be send to the transceiver, so no manual
tuning is needed anymore, when working satellites. RX- and TX-VFO will be
continuously updated with doppler-corrected data. Of course, possible
calculated transverter frequencies will be taken as source for the final
calculation of the doppler shift. So this part is 100% compatible with AO-40
or other super-high frequency satellites. Various possibilities to alter the
way to calculate the doppler shift itself are available in the settings.

Pretty easy to interface to a computer via a null modem cable which I made
on my own, using only 3 wires to make it work. I never had any luck with
Wisp, then I found this one and had a ton more features so I've used it ever
since.

Good Luck with it,
Chad
