Mac,

I used these frequencies from the @????????? Twitter home page:
Uplink 437.500 MHz, 141.3 Hz CTCSS
Downlink 145.900 MHz

I had no trouble getting into PO-101 on three passes during Field Day.  I
was able to talk to myself for all three passes for the entire pass.

Of course, I was in Copper Center, Alaska and nobody else within range was
heard.

My point is that these frequencies worked, so the AMSAT website and their
Twitter home page are most likely correct.  My station was a standard Arrow,
IC-9700, with manual tuning.

 To add a bit of personal experience - calibrating the uplink forced both
stations "walk" the band during the QSO.? Eventually, realized that
adjusting the downlink instead was a better choice, and has been smooth
sailing since.?

Technically speaking, the calibration of the downlink takes care of
abnormalities in the entire chain and that lets the program (SatPC32 etc.)
ensure that the uplink is spot-on any time you pan the downlink, during the
pass.?

(Disclaimer - while there are a different schools of thought, the above is
solely based on personal observations, failures and successes. Individual
mileage may vary.)??

 Hi,

The manual is your friend.? The secret sauce is to adjust your uplink on
the CAT menu until you can hear yourself, then save the uplink calibration.
Trying to tune the radio knob caused both the uplink and downlink to change
and is not how you calibrate things, but is exactly the behavior you want
(manually tuning to find someone to call, and being spot on with your
downlink too.? I do feel sorry for the folks, hundreds (thousands?),
vainly sending dots/dashes during Field Day attempting to find themselves.
The secret sauce is to do that before Field Day.? With the exception of
AO-7 which was unusually far off, all the other dozen+ satellites were
within a couple hundred hertz or less of the calibration values I use at
home on my 9100 (in a fairly stable thermal environment).

Good luck, but rest assured that SatPC32 works great controlling Doppler.

That's what I was using.?? Like I said, I was probably just
out-gunned by more powerful stations.

Hi,

I think the problem started from this "official" site[1] where the
frequency is listed as 437.700 MHz.

According to the twiiter account of Diwata-2 satellite[2] this is an old
site and needs update.

The right frequency is the one coordinated by IARU[3] and also listed in
the description of the twitter account of Diwata-2[4] and it is indeed
437.500 MHz.

73,
fredy

Rick, there is a new option in Hamlib specifically for the G5400B +
FoxDelta combo (about a month old). Might want to try that as it solved all

There is a first for everything. So today for the first time in my 10
years as an amateur radio operator I experienced that my KR-400 rotator
(partially) stopped working. It has not been in use for 10 years, only
the last 8 months and the motor was cleaned and greased before the
install. Before I start dismantling everything I would like to see if
any of you have any good advice.

The problem --- it will turn right, not left.

What I measured --- between terminals 5 and 6 (right turn) I measured 31
Volts, which is normal. Between 4 and 6 (left turn) only 21 Volts. Rotor
not connected to the controlling box when measuring.

My thoughts --- must be in the controlling box. However, there is simply
nothing there in the circuit that I think could act up. From the
transformer one terminal carrying 29 Volts goes to two switches. The
other terminal is neutral. There is the light bulb between the two
terminals and a 70 uF/50V capacitor between the two switches.

I could be entirely wrong, so spill any info and/or tips that you can
give me, here. Cheers,

Hans

Only 4 short days till  #JosephOrBustRove

While DN15 is my MAIN Goal I will be in DN05 as well for 1 or 2 passes.

I will be operating as W3ZM/7 while on this trip, and it will be logged
that way.

But when we play that forward to launch time, the satellite is about 10
minutes ahead of the launch. So take it with a grain of salt.

Our best guess is as follows.  This is delta-time from launch (planned at
0330z) (USNA is our ground station here in Annapolis, MD on the USA East

Sorry for the late reply.  I've been a bit buried in other tasks.

I don't think I have seen this issue before.  I have seen the issue were we
keep requesting a file, even though it is fully downloaded, because
FalconSat-3 changes the timestamps when it updates files.  But I have not
seen this issue.  So I have logged it here:
https://github.com/ac2cz/Falcon/issues/43

I'll check the code and see if I introduced an issue with some changes I
did to fix another bug.

Can you send me the file that you have difficulty uploading?  Or attach it
to the github issue?
