Roscosmos has announced the ISS will be reboosted 3.7 km tomorrow. Since

we should see almost 5 seconds of change. Usual caveats about tracking

It needs to be updated by the LoTW folks. My understanding is that all the
IT resources have been occupied with the cutover to the new ARRL web site.
It wouldn't hurt to drop a polite note to the LoTW folks. Squeaky wheel and
all. ;)

John,
I meant to mention a nice page discussing Doppler shift. It explains many
of the questions/comments/rants brought up about Doppler shifts and
corrections:
http://www.qsl.net/vk3jed/doppler.html
It gives a few graphic illustrations of how Doppler shift varies depending
on the pass, and why
Greg,
A good compromise, and I certainly understand the desire to remain in the
loop. It allows the other operator to take advantage of greater automation
or not, as suits them.

John,
MacDoppler, SATPC32, Ham Radio Deluxe, and other programs all support what
has been called the One True Rule. The usual name for the implementation is
Full Doppler Tuning. You are doing it right. When everyone does this, it
provides a very pleasant opportunity to talk instead of tune. It
Hi,
I came across the post below on a Usenet group. I am only a very occasional
ISS APRS user, but have noticed several of the regulars here when I do
operate. My impression is that it is either largely a non-problem, or
better solved through the APRS client. Can anyone suggest a good answer

SATPC32 will work perfectly on your OS and version. (Plus many others!)
Same as mine.

Guy,
Mode-L is not authorized for transmission FROM a spacecraft, only TO one.
So you only need TX capability. Of course the rigs you mentioned will give
you the needed TX capability. A cheaper way would be to find a used
transverter. Note that unless it was designed for satellite use, it will
Last year at Dayton, where it was not so much announced as broadly hinted
at, I asked and was told that it was planned to have all the satellite
functions of the D7, plus a thorough modernization for components and
features. It will be interesting to see whether they deliver on that.
After being b
One thing I would like to see tried, perhaps for one FD as a test, would be
to relax the restrictions on FM mode contacts where one or both of the
frequencies is above 70 cm. That would certainly encourage people to try
L/U or V/S. Based on last year's numbers, every L/U station could have
worked
Peter,
>From past studies, mode L/U is the place to be if you want to work someone
on AO-51 without an EME station. ;) While the V/U FM repeater was choked
on every pass, there were very few stations on L/U. In the four passes I
monitored last year, totaling 46 minutes, there were only 21 stati
Thanks for the reference.
It will be interesting to see when, and by how much, the orbit is adjusted
over the length of the mission.

Also hearing them. Be certain, if you can, to try different polarity. It
does make a difference.

Roger,
As Mark said, it is probably either a QTH or a KEPS issue. Most likely QTH,
since by default they look at the same keps. I keep ITrack around to break
the tie whenever there is a discrepancy with other programs. That tells me
where to look for the glitch. While not as detailed, the real
