Mike,
The YouTube video wouldn't open so I can't be entirely sure of what your
issue is but it sounds like your RF gain is turned all the way down. This
would give full scale RX reading and allow almost nothing to be heard.

Hi Rick,
I'll see if I can offer any additional tips. I'm sure if you have questions
other guys will have some also.
> ... set up UISS with SoundModem to work with my Flex5000A.
There are some changes in UISS settings to work with Soundmodem (Figure 10
in the article) which you likely have made. I start Soundmodem first
followed by starting UISS. When UISS starts it shows a message that it
connected with Soundmodem:
Connected to Server 127.0.0.1
Port1 with SoundCard Ch: A;
On the UISS main screen I set these pulldowns (you can manually type in the
values if they aren't in the pulldown menu):
To as CQ
Via as ARISS
TX Text/Data as =4211.29N/08827.08W-Greetings (my lat/long, the "-" is the
code for the house symbol on the map, and Greetings is whichever text you
want to use for CQing. When I click the Text/Data F5 button it transmits.
On the Soundmodem settings I've selected AFSK AX.25 1200bd and I left that
little window set at 1700 which seems to be a default.
One note about the soundcard packet applications is they will only display
packets that are 100% correct with no checksum errors. I miss the feature on
hardware packet where you could PASSALL to the screen including the
incomplete packets. Some packets sound "good" but if it contains a checksum
error the software won't display the message.
I don't know if the Flex 5000 needs any additional interface settings. I've
observed what Alan mentioned that Soundmodem on receive is pretty tolerant
of levels. I'm seeing different sound levels on receive here between
different computers. I know my FT-857D is sensitive to transmit sound levels
and I need to use the Windows audio mixer slider to keep the FM deviation
within limits.
On another computer running an SDRPlay for receive I've observed that
VBcable always seems to run with higher levels but Soundmodem decodes OK.
> ... clues how to set up UISS for terrestrial APRS packet on
> 144.390 to enable me to test this setup by getting some feedback
> that shows things are working?
When I listen on 144.390 for testing all I see is the raw APRS data. I don't
transmit on 144.390 since I'm not active on APRS (cool maps though). The raw
APRS packets look like:
1:Fm W9RCG-2 To APU25N Via K9ESV-10*,WIDE2* <UI C Pid=F0 Len=61> [09:43:58R]
[+++]
=4307.10N/08807.20W#APRS&DIGI @ Menomonee Falls, WI {UIV32N}
I find it useful to see some test signals on 144.390. In the mishmash of
callsigns and routes you can tell who transmitted the packet by the
asterisk. The only path information you need for ISS packet is the UNPROTO
set to CQ VIA ARISS. I found that the settings to decode terrestrial packet
transfer directly to receiving packets from the ISS and PSAT even though the
content details differ between terrestrial and space.
The map on http://www.ariss.net/ only shows that stations that were received
by a satgate station. Sometimes half of my packets aren't gated via satgate
to the internet even though I received my own (and others) packets directly
at my station. This web page will still show you if you were satgat'ed
without you sending APRS information. You'll see your transmitted text
without position information. If you transmitted position information that
would be displayed on the map portion of the web page. (That map is zoomable
so you can get close-ups on your area.)
I guess it goes without saying, but I'll say it anyways, tracking the
Doppler shift on 437.550 is important on both the transmit and receive legs.
Packet on 145.825 will be easier once they get the chance to install the new
Ericsson radio.

I have seen the question arise as to why some satellite contacts uploaded
to LOTW show up as 2m, 70cm etc rather than satellite. I have one contact
with Venezuela that is like this. In It appears that I uploaded using
"prop_mode sat" like it should be. It also appears that the other station
must have uploaded it as a 2m contact. Thus it is credited as 2m's. Am I
thinking right here? Has anyone found this to be the reason for this type
error?

Message to US Educators
Amateur Radio on the International Space Station
Contact Opportunity
Call for Proposals
Proposal Window February 15 ? April 15, 2017
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew
member on board the ISS. ARISS anticipates that the contact would be held
between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits
will
determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of
participants and integrate the contact into a well-developed education
plan.
The deadline to submit a proposal is April 15, 2017. Proposal information
and documents can be found at www.arrl.org/hosting-an-ariss-contact.
The Opportunity
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.
An ARISS contact is a voice-only communication opportunity via Amateur
Radio between astronauts and cosmonauts aboard the space station and
classrooms and communities. ARISS contacts afford education audiences the
opportunity to learn firsthand from astronauts what it is like to live and
work in
space and to learn about space research conducted on the ISS. Students also
will have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight and
the complexity of scheduling activities aboard the ISS, organizations must
demonstrate flexibility to accommodate changes in dates and times of the
radio contact.
Amateur Radio organizations around the world, NASA, and space agencies in
Russia, Canada, Japan and Europe sponsor this educational opportunity by
providing the equipment and operational support to enable direct
communication between crew on the ISS and students around the world via
Amateur Radio.
In the US, the program is managed by AMSAT (Radio Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with
NASA and
CASIS (Center for the Advancement of Science in Space).
More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.

Hi Mike,
I don't believe there is anything wrong with your receive...? the 'static'
you hear IS the AO-85 downlink.? The transmitter is on and transmitting and
the signal strength is going up and down due to 'tumbling', ploarity
shifting, etc. The reason you hear static is that it's not like SO-50;
instead of squelching when there is no signal, AO-85 simply rebroadcasts
what it hears... which at the moment is 'nothing', SO it is passing the
white noise from it's UHF receiver straight to the 2m transmitter.
Eventually you heard a voice there at the end, so yes, you ARE hearing it.
If I read the TS-2000 manual correctly, your problem is that you have the PL
tone set on the receive band... not the transmit band. The 'T' should be
above the sub band display in other words. So since you are not transmitting
the proper PL tone of 67.0 Hz, you are not able to hear yourself come
through the transponder. See about fixing that and give it another try. And
from experience, I'll suggest to double check that even after you get the
'T' on the correct band, verify that it's 67.0 Hz.? =^)

Rick,
In your original post, you said " I have no decoding packets whatsoever either
from ARISS or terrestrial on 144.390." Since RX is in fact working, the most
likely transmission problem with the Flex is that compared with traditional
rigs, there is considerable latency, or delay, between the audio input and
transmission. The result is that the transmitter cuts off before the full
packet is sent. Fortunately there is a parameter, TXtail, which will keep the
transmitter keyed for a period after the audio is sent. Somewhere in
Soundmodem, probably the Modem tab, IIRC. Try setting it for 500 ms or so,
and see if that helps. It solved my problem. After you get it working, you
can cut that back a bit, if desired. How much is a complicated function of
sampling rates, buffer sizes, etc.
Another issue is deviation. Too much is much worse than too little. I find
that setting VAC at -14 gives me 3 KHz deviation.
73s,
Alan

Thank you Roy and Paul for your replies .
The plan is to move back into a motorhome. Weather this actually
eventuates or not depends upon finding a buyer for our house. No doubt
any buyer will not be interested in my current extensive station.
Anyway, I'm just exploring far simpler station options at the moment.

Actually the PL tone on AO-85 just turns the repeater on. Once it's on,
there's no tone required until it times out...that's why you hear the noise
on the uplink.

AO-85 and Fox-1B/Cliff/D will start the transmitter "hang timer" when
they detect the CTCSS. The tone must be again detected within 60
seconds in order to reset the hang timer else the downlink transmission
will stop. By having your tone on your uplink signal all the time, each
time someone keys it resets the hang timer.
