I told a friend of mine, Bob, KC7QR about AO-91 and he gave it a try.? He is
in Jerome, Idaho and he attempted to make a couple of contacts today,
Wednesday, Jan 3rd at approx 2109Z.? He said someone from Arizona tried to
contact him as well as another station in Illinois.? If those stations could
let me know, I will pass it along to Bob.? I am a member of the Magic Valley
Amateur Radio Club in Twin Falls, Idaho even though I am in Washington.? I
am trying to generate some activity in the Idaho area for some grid squares
and it looks like the seed I planted is growing.? Thanks for anyone who
responds.? 73'...Ed? WA7ETH? AMSAT 16226

Hi Dave,
When you say your doppler is too far ahead or behind, do you actually mean
your overall frequency, or do you mean your split distance?
If you mean your overall frequency then that's really odd, as SatPC32 has
always put me smack bang in the middle of the pass-band if using linears
(with the correct locator set on login). If this isn't the case you can
adjust it in the settings files, but it's generally calculated based on your
locator and the Keplerian data you can download (and should be updating
every time you open up the app). If, however, you mean your offset (ie
finding your own downlink) then this is always a bit variable for me, but
usually pretty close.
SatPC32 does, in my experience, remember your offsets when you adjust them
(in my case either with the + and - buttons, or the pot at the top right of
the rig), so that next time you hit that satellite it keeps the same
offsets. You may find your offset is slightly different on different passes,
or you may find it's exact every time, but that's part of the fun with
linears - finding yourself first!
Hope that helps.

John (XLX)

10 Laptop.
Message-ID: <18d1a0f7-438a-d223-f28d-049d97989e0d@xxxxxxxx.xx>

Hello all,
I want to use 2 FTDI USB-to-Serial converters (US232R and FT4232H) with
my? Laptop Acer Aspire with 64-bit Windows 10, Home edition. But the
installation? of the (latest) FTDI drivers fails. I tried automaic
installaion via the Windows Device Manager and manual installation by
running the .inf file. With both methodes? I get the same? Windows error
message, saying that Windows found drivers for the device, but an error
occured during installation, see screenshot. ? When I check the hardware
for problems Windows says that there are no drivers installed for the
US232R/ FT-4232H.
With a Toshiba Laptop and a Cativa desktop PC, both also with 64-bit
Windows 10 Home, the installation worked flawlessly and the adapter
generates the virtual COM ports
I googled for a solution but without success. There are more users who
report the same error message with other USB-devices. There was a
suggestion for Windows 7 to delete a file named InfCache.1. I can't test
that, however, because? Windows 10 doesn't provide that file, the
content has been moved to the registry.? The FTDI support suggested to
first uninstall the drivers, but the problem remains.
Has anyone else encountered the same problem and is there a solution?
Many thanks for any support
73s, Erich, DK1TB

Alan. I hope I'm missing something, but I tried to run this and I get the
same link to the 'error opening help in windows' error. I went through the
original messages and find no reference to 64 bit win10. All I have up here
is win10 64 bit systems, so I won't be able to try a win7 install until I
get back to Florida. My question is, does anyone have this working with 64
bit WIN10?

Chris,
There is a way to restore the functionality of old format help files.
http://wa8lmf.net/miscinfo/RestoreWinhelp32.exe
It adds old files, no longer supported, but does work up through WIN10, 32-
and 64-bit. Works fine with WiSP.

Ya know, you could MANUALLY tune. It does work. In fact I strongly

Indeed. I manually tune all the time. No interfaces to deal with and never a
problem finding my downlink. Very much worth a try.

Hey now, don't shoot the messenger! The vast majority of my AMSAT
demonstrations are done with groups of scouts of various ages, and the last
thing they need to see is me focussing more on the radio than making sure
they understand what's going on!
If I've got a piece of software that can correct for doppler shift for me,
and it can manage pointing my antennas in the right direction, then it
leaves my focus available for the actual operating, and the explanations to
the young people who could well be the next generation of amateur radio and
AMSAT enthusiasts ;) I think that's a far better use of my resources than
sitting there with my back to the people I'm supposed to be introducing to
the hobby, and focussing on turning dials and pushing rotator controller
buttons...

I'm glad you mentioned scouts, John.
I counsel for the radio merit badge for our local scouts, and Elmer our
local middle school's radio club. In the club last month, we completed tape
measure yagis. And, for this month's radio club meeting, I was planning on
having the kids working a couple of birds passing during the meeting time.
I figured that with 10 kids, we could have them in teams for tracking,
tuning, recording and operating under my supervision. I thought it would be
good for them to try to do everything manually once for two reasons. One is
to show that's it's doable on a minimum budget by a teenager. And, the other
is so they'll have an appreciation of everything our more automated rig will
do during our ARISS QSO in March.
From your comments, I'm rethinking that strategy a bit. Do you think that's
too much?
73!

Nobody asked me but I would just start with just listening and
gradually adding more components to the mix. Listen to AO-91 on at
least one pass because the downlink doesn't require much doppler
tuning if at all, then try SO-50 and learn doppler tuning, add audio
recording on another pass, add uplink capability towards the end.
