I am trying to get SatPC32 v12.8 to automatically tune my FT847. When
the program first comes up, the radio is initialized as indicated by the
"CAT" display and when I click on a satellite, the radio tunes to the
correct satellite. That's where it stops; it no longer changes the
frequency of the radio. If I turn off and turn back on CAT control, it
will update once and will then quit again. I have the same problem with
my FT-857.
I have read the help and .SQF files, but I cannot seem to find the right
combination. I have changed the baud rate of the radio and the program
to 4800, 9600, and 57.6k and made the corresponding changes with the CAT
delay value as recommended by the manual. I have not yet tried
uninstalling and re-installing the app.
I am running Vista 32bit and using a USB-to-serial converter which works
with everything else. The same converter works with the HRD 5.0
Satellite Tracker. Problem is, I cannot get HRD to accept sub-audible
tones so I can work AO-51. I don't know if it's a limitation of the
program or cockpit error.
Any suggestions, known issues, or anyone else having the same problem(s)?
Thanks,
Joel, W4JBB

hi i can help, i have reason to believe the SatPC32 does not like some usb
converters, i "had" some with the FT-857d and things like you described
happed to me also
changed to a straight usb cable for the radio and the problem went away
(FT-817nd also)
auto tune worked,
?
your second problem?no need for tones for AO-51, SO-50 yes (typo??)
i just set the tone in the TX radio and not the software and works good with
both programs
at least for me,i use satpc32 just my preference.
hope that helps

Hi Loren,
I have an old ICOM R-7000 "Communications Receiver". It covers 25mhz to 2
ghz with a small gap from 999mhz to 1.025 ghz. The old "cell" band is *not*
excluded, not that you can hear anything there anymore. It covers all modes
- narrow, medium, and wide-band FM, AM, and SSB/CW.
I use the rig mostly as my S-band IF receiver, and for in-shack coverage of
scanner stuff (police/fire/etc.) outside the ham bands (my other non-HT
radios are ham-bands only). As an IF receiver it does work pretty well, and
it does have a 10.7mhz IF output in the back. Be careful, there is a 9v DC
bias on the connector (used for powering external equipment). It's also got
ICOM's computer control (CI-V) interface, for computer-driven Doppler
tracking and such. Drift has not been a problem at all, and I haven't had
any trouble with birdies, at least nowhere of any interest that I can
remember.
But, as a general coverage receiver or scanner, it's 20-year age clearly
shows. First of all, it's a bit deaf by modern standards. The local NWS
weather channel is an S6 or S7, being fed by a very large TV antenna, with
Preamp, in the attic. It's full scale on my HT with its rubber duck antenna
in the shack. My S-band equipment (Drake 2880, and all that) barely gets
above S1 or S2. You get the idea. The "scanner" is also pretty limited
(i.e. slow), and it has no concept of trunking or any of that sort of stuff.
The front panel controls are also a bit of a puzzle, in that one of the
most important controls is on the BACK: You choose from wide or narrow FM
on the front, but your choices are 6/15 khz or 15/150 khz, and the group is
chosen by a tiny slide switch on the back of the unit. I have no
significant use for 15 khz, and you can't pick 6/150 as a combination.
USB/LSB is also a back panel switch, but nothing much is ever LSB above 25
mhz so that's not a big deal.
It does have a significant role in my shack, and I wouldn't trade it for
anything except maybe the R7100. Prices now are quite reasonable, if you
can find one.
Good luck in your hunt,
Greg KO6TH

Hi Joel,
the program updates the radio frequencies only when the change of the
Doppler shift of the higher of both frequencies (with AO-51 mode V/U the
downlink) exceeds the "interval". The interval for FM sats is 600 Hz by
default (menu "CAT"). Decrease it to - say - 50. Then watch the change of
the Doppler shift of the downlink in the SatPC32 frequency window. When
the Doppler shift of the downlink changed by 50 Hz or more the program
should update both radio frequencies. See also sect. D 4 (menu "CAT") in
the manual.
73s, Erich, DK1TB

Simple, visit www.kiwisat.org and learn of the extreme difficulties ITAR
imposes on our project.
We may use soft words but the effect has been devastating, setting our
efforts back by years. Search the archives to see that AMSAT-NA has ordered
its USA members to cease co-operating with us!
And before anyone reacts, we are having meaningful discussions with
AMSAT-NA, and the solutions are to hand, provided one of our generous
members wins the Lottery!
Terry.

Hi Joel, I had to play with the baud rates to get it tracking. Still
have a couple issues but it does fine.
Try lowering the rates on the com port and match it with that in the
program and see what you get.

Nothing like getting a reply from the author. :) Thanks, Erich, that
worked. I set the CAT interval to 50 and all is well.

me to pack my bags and go West to DM90, so this afternoon on the 2351z pass
I will try and be in DM90 for those that need it. I am here 2 days, and plan
on working all 3 FM birds one time or another.

There has been a lot of discussion about using PDAs and the like to do
satellite orbit prediction. Indeed, I've thought about writing my
own satellite prediction stuff for the iphone, but haven't bothered
yet, mostly because i find that having another electronic device that
I am staring at while I am pointing an antenna with one hand and
playing with the HT in the other isn't at all helpful. Here's how I
work a pass:
1. Early in the day (hours ahead of time) I run a prediction for the
satellite of interest. Minimally, you need to know the time of the
AOS and LOS, the maximum altitude of pass, and azimuth at which these
events occur.
2. Make sure you know where north is. From your home QTH, it
probably is easy, but I carry a compass for mobile operation just in
case.
3. You need to know what time it is. Accuracy to 30 seconds is
probably reasonable for hand held operation, where you might not work
down to the horizons anyway.
4. At AOS, aim your antenna near the horizon at the AOS azimuth.
Don't bother sweeping left and right all that much if you are pretty
sure of your directions: the sat will come up on target. For 70cm
downlinks, start 10khz high for the LEO sats we currently have up.
5. Work the pass. If you know the azimuth and altitude and time for
the max elevation, you can with a glance at your watch "interpolate"
the satellite pass pretty reasonably. It may help to have a couple of
other times/locations along the path, but isn't strictly necessary,
particularly if you have full duplex, since you'll be able to hear how
you are doing in working the pass.
Honestly, having an interactive display wouldn't be all that useful
during the pass. For one thing, I don't have another hand to hold
it. Additionally, it's not like the satellite is going to do
anything unexpected: it will be coming up exactly as expected, and
setting exactly as expected.
One thing I am working at is a script to create Google Calendar events
that are automatically synched to my iphone. That way, I can get the
details of each pass automatically a day in advance. Just having
that static data on my phone (which I am seldom without) suffices for
95 percent of all my operating needs.
I should thank WB4APR and K7AGE for their satellite operation tips.
Bob points out that satellite orbits are regular, and hence can be
easily predicted ahead of time, and a simple printout will show you
within a minute or so when the pass will occur...
http://www.aprs.org/sset.html
Randy, K7AGE used a printout of the pass taped to his HT in one of his
videos, which I did when I started, but later I realized that if I
just "rehearsed" the pass in my head and had a watch, it wasn't
necessary.

Mark,
Thank you for this post. I hope you don't mind if I add a couple thoughts:
1 - Brunton (and, I suspect, others) makes a baseplate compass (the kind
used for orienteering) that includes an elevation scale on one end of the
base plate. Brunton used to make one that was intended for those mounting
satellite dishes, and that scale went up to 60 degrees elevation. Their
current model only goes to 30 degrees, but it still proves useful in
visualizing an upcoming pass.
2 - Nothing beats observing visible passes of the International Space
Station as practice for satellite passes. Because it orbits lower than our
amateur satellite, passes unfold a few minutes more quickly than, say, a
pass of AO-51. Even so, I found that several years of watching visible
passes really paid off when it came to visualizing a pass.
3 - Use easily indetifiable landmarks to help guide you through a pass. AOS,
for example, occurs in a line with that mailbox off there to my left.
Mid-pass will be almost directly above the chimney of that home over there.
And LOS will occur in a line with that street light.
73 to all,
Tim - N3TL
