The sound card is set for "2 channel 16-bit, 48000 Hz (DVD Quality)." I
am not aware that AGWPE lets you set a sample rate for that application.
I have a vague recollection of changing the sound card sample rate from
44100 Hz to 48000 Hz in order accommodate my Alinco DJ-X11T, but I don't
recall any sample rate change affecting AGWPE performance on this laptop.

It's merely on the short list of things that I check when these sort
of symptoms show up. Next would be changing the output/input sound
level settings. Low/lower early in the chain.
I use direwolf. It gives a signal strength report with a received
signal. Software manual has optimal window. Also can do bit flipping
to recover unrecoverable packets. (corrupted data retrieved by
compting the checksum).
Can you record the RF on an SDR and make multiple tries decoding?
Neatest thing is that RF becomes digital. Store record forward reverse
fold spindle and mutilate.

Hi folks,
I own the Yaesu G-5400 rotators ( Azimuth and Elevation ) and the Yaesu
G-5500 complete with the Control Boxes.
As I have problems with both the G-5500 Azimuth and Elevation Rotors and as
I still have both the G-5400 ones, I would like to know if I can use both
the G-5400B rotators with the G-5500 Control Box or I need by force the
original ones?
I saw that the difference between the two Control Box is the Azimuth
Display, that the G-5400B one has on the left and on the right side of the
display: 180 S, while the G-5500 one has on the left side of the display: 0
N and on the right side of the display 90 E.
Please anybody can help me to avoid any damage?
Any help will be really appreciated.
Thanks in advance

Asked myself the same question a few days ago.
Shouldn't damage the rotator if you use the control box as a drive
unit, rather than as an indicator (will be wrong, as the g-5400 is a
360 adnd g5500 is 450). Use a K3NG arduino rotator connected to the
aux plug on back as a controller. Can use relays or transistors to key
the aux control lines.
Do note that K3NG's code needs to be cofigured correctly: I.E. total
rotation and center.

Enzo,
Unfortunately the rotators used in the G-5400 are not quite the same as the
G-5500.
They both use a phase shift capacitor for full torque, and also a method of
protecting the motor in case it hangs. In the G-5400, the azimuth rotator
has the capacitor in the control box, and uses thermal limit switches. The
elevation rotator has the capacitor located in the rotator housing, and uses
mechanical limit switches. In the G-5500, both units have the capacitor in
the rotator, and mechanical limit switches. For completeness, the original
Kenpros, which Yaesu acquired, had the capacitors for both in the control
boxes. There are reasons why mounting the capacitor remotes is better, but
it is much messier to replace, and more likely to fail due to the
temperature extremes.
73s,
Alan

Not very difficult to do. Got it at the motor shop locally. Dude

Three wires: One for motor left winding another for motor right

Yes, I can, but I'm not complaining about performance. The point of the
TH-D72A vs. IC-02AT test was to see if evidence existed to support the
notion that there might be some anomaly with the new ISS APRS system
that might explain why some operators (Scott, K4KDR and others
apparently) are unable to decode packets now when they could previously,
either on 70 cm or 2 m. If my comparison test had come up, say, 13 to 2
packets decoded in favor of the TH-D72A, that would lend credence to the
notion that such an anomaly might exist but is masked by the better
performance of purpose-built (i.e. designed for packet/APRS) equipment
like Kenwood and Yaesu transceivers.
When you have a measure of experience with something like ISS APRS
reception, it's easy to brush off reports like Scott's and just chalk
them up to operator ignorance, operator incompetence, simply forgetting
a step or two in a setup process, etc. But Scott is asking for some
help (a sanity check), and I was just trying to perform a few
independent tests. There are plenty of other operators who could do the
same thing.
So now the question would seem to turn to things like:
What do Scott's station and the others have in common (if anything)?
Are they all SDR type stations?
If they are SDR stations, are typical SDR stumbling blocks handled
properly (offset, center spike at 0 Hz offset, etc.)
Are the station components and transmission lines well shielded?
Have local interference sources come into existence on or near 145.825
MHz since the ISS was previously on that frequency?

See the below announcement of our DXPedition to St. Barts in October. I
plan to operate several satellites this time and to concentrate on
evening passes when they are available. Equipment will be (as it was on
Montserrat in 2015) an IC910H and Arrow. I'll again announce the passes
I'll operate here on amsat-bb in advance with updates during the
expedition. Callsign will be FJ/N0KV. Satellite QSOs will be uploaded
to LOTW either during or immediately after the trip and paper QSLs will
be available from N0KV; please provide an SASE.
Jim, WD0E
AI5P, N0KV, W0ZA and WD0E plan to operate from Pointe Milou, St. Barthelemy
Island (IOTA NA-146/Grid Square FK87) from October 17 - 26. Operation
will be on
80-10 meters (SSB/CW/RTTY) with satellite operation by WD0E. Conditions may
largely limit most activity to 20 meters and down. Operating 160 meters
is being
considered; however, no antenna option is yet finalized.
Satellite operation will take place on several satellites. A satellite
and pass
schedule will be announced on the AMSAT-bb in advance.
Equipment includes three Elecraft K3's and two 500 watt Elecraft amps.
Antennas
include a SteppIR crank IR vertical for 80-10 meters, a folding hexbeam by
Folding Antennas (Germany) on 20-10 meters, LPDA's on 20 and 17 meters and
verticals on 30 and 40 meters.
Operation will be as continuous as conditions warrant. The Colorado
operators have
decided to use FJ/N0KV as their callsign while AI5P will be active as
FJ/AI5P.
FJ/N0KV logs will be updated to LOTW while Rick's logs (FJ/AI5P) will
not since
he continues to be an analog guy with an actual key and pen/paper log.
Paper QSLs will be available from both N0KV and AI5P direct and via the
buro. US addressees send SASE; addressees outside the US should send SAE
plus $2 for return postage.
Use of Club Log is not anticipated.
Further information will be published as the trip approaches.

I have been informed by the captain that Gale warnings with waves to 15 feet
have caused them to delay our trip as the safety of us and the vessel would
be in serious risk. I will be working with them to reschedule in the
morning. I'm truly disappointed that weather has forced us to delay but the
seas are unforgiving and all of us need to make it back home. As soon as a
new date is set I will notify everyone. I hope to have the new date figured
