Guys, hope in an help.
I have mounted the 38k4 Baud into my Kenwood TS-2000X.It has been mounted
from the technical that make the 38k4 baud board.
When I saw the radio after the modifications I have noticed that, he has
used for the RX and TX connections the ACC2 Connector.
Now I have two ACC cables that I have to keep plugging and unplugging. I
mean when I have to do Terrestrial data communications
like RTTY BPSK Packet etc. I have to use the old ACC2 cable, When I have to
use the 38k4 I have to use the new one.
Anybody can suggest me a way to avoid to plug and unplug the cables when
necessary?
Any help will be really appreciated.

Years ago when I modded my FT-847 to RX 38k4 baud from the pacsats I left
everything connected and used a simple multi pole switch to go back and
forth. I had everything wired to the same ACC jack. I still have my Symek
38k4/9k6 TNC3S, but no receiver to go with it if anyone is interested :-)

I'm using a G5400B for portable operation and controlling things with
SatPC32. The rotor interface is an older FoxDelta serial port version which
is using the EasyComm protocol. My question concerns the software in
SatPC32, specifically the carriage return/line feed specification. Should
either of these be checked in the rotor control aspect of SatPC32?

I'm not following the thread, but are you using the THD74 in SSB receive

Yes, and I find the TH-D74A works very well as a receiver for the linear
satellites. The Elecraft KX3 has greater sensitivity if the preamp is
enabled, but at the expense of deafening background noise. In contrast, the
TH-D74A has very little background noise in SSB mode, so copy is much more
"comfortable."?
The tuning knob is much easier to control than that of the TH-F6A, with much
less frequent inadvertent turning of the concentric audio volume knob while
tuning. Even when I do accidentally turn the audio volume knob while tuning,
audio level is unaffected when using the Bluetooth earpiece, which I find
works very well for SSB, not so well for FM.?
This is a link to a description and photo of my pedestrian-portable radio
setup:?https://forums.qrz.com/index.php?threads/kenwood-th-d74a-for-satellite-
work.540096/page-11#post-4746587
I also hope to use the TH-D74A much more frequently for packet work once ISS
and BIRDS-2 are operational.?

Information and its organization is a relevant issue nowadays where so many
webs, whatsapp groups, twitter, etc., supply us with interesting news.
I think AMSAT needs a meeting-point on his web where whatever ham can spot
its portable/event activation, so will not need to subscribe to several
webs, forums, whatsapp groups and twitter.
We only need to visit the web of AMSAT each moornig to see the folllowing
rare grids or events activations during the day.
I hope to see it some day.

Hey all,
Nearly one year ago I installed two cross-yagis on a Hummel Teletower
with a YAESU G5400B rotator system. I have made a lot of thoughts on how
to "wind" the coaxial feed lines around both: the azimuth and also the
elevation axis. With elevation I am very fine, but maybe this is just a
matter of time as it seems to be with azimuth!
Some days ago I found some flipping faint/strong signals on my SatNOGS
station (https://network.satnogs.org/stations/37/) in the 2m band. First
I thought this could be some kind of frontend-overloading with the RF
amplifier, but it turned out: this is not!
Today I ran some tests while driving the antenna with my YAESU FT-847 at
minimum output power (around 1.5W). I could see that with elevation
rotation everything is fine from 0? to 180? el. Then I tried to turn the
azimuth and - guess what? - SWR "jumps" at around 270? from 1.1 to >4!
That truely indicates a broken cable.
As I installed that wires, I made a short connection of flexible coax
cable (HIGHFLEXX 7) from the phasing line box, down the mast and made a
connection to ECOFLEX 15 running into the shack. The flexible lines are
"wrapped" around the azimuth pipe with a radius of around 30cm. I am not
sure, but it could be broken just on top of the N-connector... Do I need
to somehow support that short piece of wrapped line?
Any hints on how to mount the cables to prevent this are really appreciated!
Kind regards,
Patrick, DL4PD

Yes...,
But I was thinking on something more visual, such as a calendar with a bar
diagram covering all days of the activation. Something similar to the
calendar of the Outlook. Each activaron a bar.
And clearly seeing the call sign and grid. Even we could filter by FM SAT,
SSB SATs or both.
With a nice tool and a simple sight with colours more people will use it and
it will be really a meeting-point for all of us.
And even each person could configure its own filters, perhaps only
activations with couverture USA-EU.
Imagination takes lead!

Can someone please send me details as to where or how I can find data on
receiving/decoding the 9k2 /19k6 data from the XW satellites.
I can receive them perfectly, but what software do I need to decode the
data and importantly what settings should I use in the software . Si far I
have tried HS_sound modem without any sucess.
