All,
As a result of lower solar activity in the past week, the decay rate of
BY70-1 has decreased. The satellite may now be expected to re-enter
around February 16 to 19.
The apogee of the satellite has now decreased to 313 km and the perigee
has decreased to 191 km.

Just recently the big blue circle showing the satellites footprint will not
move for several minutes.the program still controls the radio for doppler
shift and rotors are controlled perfectly.Just the footprint hangs
up.OPTIONS show the map should update every 10 seconds.
It has always worked perfectly until late.
What's my problem ?thanks to all who reply !Jeff WB8RJY

February is when the XYL and I do the snowbird thing from Ohio
and stay with our Daughter's Family in SE Texas. Not willing to
give up Ham Radio during that time, I bring my SAT gear with me
and activate nearby Grids.
Yesterday, I checked out my equipment/antenna from the driveway
and worked 7 stations from EM20vg, including UT1FG on FO29.
Today, I went to EL39 and worked 18 stations on SO50 & FO29.
This location makes it easy to activate several nearby Grids since it
is almost in the corner. EL39, EL29 and EM30 are all a short drive.
I have a good spot mapped-out for EM30/31 line, too.
The activations would all be during daylight hours and probably just
on FO29 & SO50. I get very nervous doing things at night that people
don't understand!
If you want to schedule something between now and 3/4, let me know.

I have prepared my 2-m yagis. Now ready to set them up to use on the birds.
I'm thinking setting one horizontally and the other vertically, spaced
about 1 ft apart on a boom. Now, how to measure the coax and connect them
for circular polarization?
FYI, when all set up, I'll put the project details on my Dropbox with a link.
Request ideas, guidance, advice, comments, please.

Hi Sean,
I'm getting a lot of requests for various Grids down herewhile snowbirding -
HIHI. ?My plan is to mesh the passinfo with the Family skeds and publish a

I wonder if someone can help me figure this out or think through this. I
have Mode J doppler shift worked out-you start high in frequency, and the
frequency lowers as the satellite moves towards you, and then away from
you. For example, if I transmit in the exact center of the FO29
passband-145.950-the received signal from FO29 starts out above the center
of the receive passband, around 435.859 or so at the beginning of the
pass. When the satellite is overhead it is at the center of the
passband-435.850, and then moves lower in frequency as the satellite moves
away from me. This is assuming I keep the uplink frequency at 145.950 the
entire time.
Is it my imagination or is the situation reversed on Mode B. It seems that
if I transmit on the center frequency of the uplink passband, the downlink
signal is below the center at the beginning of a pass, and then moves up
and ends up above the center of the downlink passband at the end of the
pass-assuming I keep the transmit frequency the same. Is that correct? Why
would Mode B behave differently than Mode J?
You can see I still have some things to learn about the satellites.

You are correct in your observation.
The difference is that by tuning the higher of the two frequencies,
you are canceling out much more of the Doppler shift since Doppler
affects the higher frequency more. If you fix your transmit frequency
on a Mode B satellite, you'll likely drift over other QSOs in
progress.
See this article for a more detailed explanation: http://www.amsat.org/?p=1489

Interesting question,
It is a useful explanation on link provided by Paul,
http://www.amsat.org/?p=1489
Perhaps another approach is try to keep the QSO on the same frequency
correcting both stations transmit and receive frequencies accounting
dynamically for Doppler.
Transceivers with CAT, or two rigs with CAT allow to implement this.
I do this with a vintage FT-736, and QSO is just as a normal HF QSO,
no tuning, hands free during all the pass, providing both stations use
the same approach.
There are very nice programs as SATPC32, Orbitron and others that allow do
this.
I use http://lu7abf.com.ar/pass.htm (the .exe part) along with wispDDE Driver.
Using this, I see how transmit and receive Dopplers moves as the
satellite passes, thus even not having CAT Control, one can manually
correct Uplink/Downlink, allowing easily hear own return.
To contact a station heard, Downlink frequency could be changed,
application will show what Uplink to use.
Wishing nice and rewarding contacts thru the birds.
