I was wondering if anyone has tried to record a .WAV file of this bird &
decode it later on. I've seen some archived posts where MixW was used, but
it wasn't clear what the individual did to set up the software. I've tried
tinkering around myself with MixW - I played the file back & ran a cable
from the speaker out to the line in on my computer, but I don't think I had
the 9K6 protocol set properly in the program (basic changing of the
parameters didn't work either).
I guess I'm looking to "cheat" from you guys since I can't get any decodes.
Is what I'm trying to do even possible?
For a little info on my station setup:
audio is captured from the DATA port for 9K6 & higher speeds
auto track for antennas & doppler
Audio recording in 8khz mono (could there be a problem here???)
...I receive GO-32 quite well with an S-5 or better on some passes, so
receiving the signal is not an issue. Even if it's just sending telemetry
right now, it would be fun to play with the high-speed data. Is there
another program I could use for decoding the data? Any help is appreciated!

I asked sometime ago in the group, but sometimes things change and stuff comes along so I thought I'd ask again and see if any one had a mini-computer like a PdP-11 with tapes drives and the large external disk drives in the floor boxes.
As I mentioned before, just trying to find a unit to show students the older technologies as well as how to program with Cobol/Fortran.
Using PCs is the best way to do a lot of stuff, but a mini-mainframe is the visually appealing idea.
Just thought I'd ask in case things changed out there!

WB5RMG (showing his lack of understanding) said :
> Reckon is there any harm in also doing LOTW ?
Thanks to BB-responses and several email replies (and some good'ol RTFM)
I now recognize that LOTW is not 'just another QSL/log toolbox'...
A simple definition for LOTW : a contact database to make it easier for
the ARRL to confirm 2-way contacts by those requesting ARRL awards.
I'm sure that there are other benefits that I may learn of as I go
down that path; but not being an award collector, the biggest benefit I
see now with LOTW is to add my few contacts that others may be waiting
for confirmation - for their award... Seems simple enough, and I will
probably start that process before long.
Thanks again for the guidance ... HNY /;^)

89 degrees elevation pass over Europe
Nothing heared this time. I did not get over the L band uplink.
Close to max elevation while TXing I heared squelch open/close
but that was all.
Thanks a lot for joining me during these nighttime experiments David !!!

Thanks to the control station turning AO-16 back on. Heard the sequence
and then the bird was really kicking butt on its signal. I lowered my
power to 5 watts and was still banging in and this with some very "bad"
verticals that I have difficulty with on the other birds. Heard to
satellite quit during the pass and then obviously, control station came
back and turned it on again. Other then some "junk" only a couple of
stations were on.
I had a choice of AO-16 or SO-50. No brainer, stuck with AO-16.
Good work fellows,
73, Reid, W4UPD
please find a status update of the Delfi-C3 / DO-64 satellite below.
1. On behalf of the Delfi-C3 / DO-64 team we would like to wish you
all a very happy 2009!
2. Delfi-C3 is currently operational in basic mode, transmitting housekeeping
telemetry at 1200Bd BPSK AX.25 on 145.870MHz. Basic mode is the "safest"
mode the spacecraft can be in, since it transmits continuously and
furthermore commanding is easiest when in this mode. The craft has
been in this mode for a while so that we can analyze a possible issue
with the linear transponder :(. As some of you may have noticed, the
transponder has been hard to access during its last weeks of
operation, contrary to the first weeks where it performed fine. We
have performed a number of tests in order to assess this issue, up
till now it seems like the issue is in the receiver frontend. Over the
coming weeks, we will continue to investigate this issue, so whenever
the satellite is over Europe and in range of our groundstation, it may
be switched to transponder mode. In this mode, a CW beacon is
transmitted at 145.870MHz. When you hear the satellite in this mode,
please DO NOT transmit to the satellite until further notice. This
will allow us to further characterize the issue and work out a
solution, if possible.
3. All other subsystems continue to perform fine on orbit.
4. In the meantime, telemetry can still be received using the RASCAL
software package, and forwarded to our server. We have again received
a lot of frames already from various hams worldwide, thank you all for
your efforts! Note that the primary server at 184.108.40.206 is not
operational, but the backup server is and will continue to be
5. During our free time at Christmas, we have implemented a number of
improvements / bug fixes in RASCAL, the most noticeable one being an
improved tuning range of the demodulator, allowing the input audio
carrier to be between 900 and 2300Hz, instead of 1400-1800Hz. This
makes tuning much easier.
These fixes have been implemented in RASCAL version 1.1.0, which is
available for download as of now from the website at:
on this page, in the "upgrading RASCAL" paragraph, you can also find
instructions on how to upgrade to this newer version without losing your
original settings and telemetry repository.
