Two years ago, I wrote a short paper outlining the use of the IC-9100 with
an external interface (see file section of the IC-9100 Yahoo group ?
_iss_ic9100.pdf) to dipgipeat via the International Space Station (ISS).
In the meantime, I was always wondering why digipeater operation with some
of the software modem programs was not possible with the USB connection
alone. Reading the excellent description by Hans DC1RJJ (see file section
of the IC-9100 Yahoo group ? _IC-9100_PTT-CW_via_USB_modification.pdf), it
became clear to me that Icom did not enable the RTS and DTR signals of the
two virtual COM ports (required by some programs) and PTT can only be
triggered via a CI-V command or external hardware. I wasn?t ready to
perform the hardware modification as described by Hans to enable these
functions within the IC-9100. However, he pointed to a software program
that will use the CI-V commands together with programs that normally don?t
have that function. This program is called ?Icom Keying? and was written by
Bill ND0B (see file section of the IC-9100 Yahoo group).
In order to get the IC-9100 to digipeat via the USB com ports and to use a
number of programs at the same time, I had to create some virtual serial
ports to allow the use of:
1. 1. SatPC32-ISS for Doppler control;
2. 2. Sound modem software by UZ7HO to RX and forward packets for UISS
as well as TX the packets from my location;
3. 3. Run the ICOM Keying program (CI-V command);
4. 4. UISS by ON6MU for ISS APRS.
Creating the virtual serial ports was done with a software by Eterlogic (
eterlogic.com) called VSPE (Virtual Serial Ports Emulator). I use the 64bit
version for my Windows 8.1 OS, however the 32bit works fine.
First, I created pair of virtual ports that are linked. Use port numbers
that are available on your computer. I used Com9 and Com10. This pair is
used by the Icom Keying program (Com9) and the SoundModem software by UZ7HO
(Com10, which tries to trigger PTT via RTS signal which is intercepted by
the Icom Keying program and translated in CI-V commands).
Now, the Icom keying program needs a real Com port (USB Com3 for the
IC-9100 in my system) to trigger the radio to go the TX (CI-V Command).
However, SatPC32-ISS also wants the same Com port for doppler control.
Consequently, I created a splitter with the VSPE for these two programs to
share the IC-9100 Com port 3. I linked a new virtual port (Com8) to my real
port Com3 and pointed both programs (SatPC32 & Icom Keying) to Com8 the
virtual Com port for sharing.
Starting everything up requires a little bit of a sequence:
1. 1. VSPE needs to be running
2. 2. Start the Icom Keying program
3. 3. Start SoundModem
4. 4. Start UISS
5. 5. Start SatPC32-ISS
This way, I am now able to do APRS digipeating without any additional
hardware just using the one and only USB cable between the IC-9100 and the
PC.
Let me know if you have questions,

Subject: [amsat-bb] 73 on 73 Award Reminder
Just a reminder that the award period for the 73 on 73 Award begins at
0000Z on September 1st, so begin keeping track of the unique callsigns that
you work on AO-73. When you reach 73 unique callsigns in your log, email me
at n8hm@xxxx.xxx with a list of calls, date, and time worked (in UTC) and
your mailing address. I hope to have a website up soon with an example of
what the award will look like.
Some tips for working AO-73:
-Keep in mind the frequency drift on the transponder. The offset needed on
your transmit frequency is usually from +10 kHz to +16 kHz. This can vary
throughout the pass, requiring frequency adjustments if using computer
control. Many find manually tuning the uplink to maintain a constant
downlink to work better than computer control.
-I usually start a pass by trying to find myself come into the top
edge of the passband (145.970 MHz). To do this, I usually start
transmitting around 435.135 MHz and tuning up slowly until I can hear
myself enter the passband. Then I can move around the transponder
easily. Remember to tune your uplink to maintain an constant downlink
frequency (the opposite of FO-29).
-Keep power output down. The transponder has a very sensitive receiver
and a very active AGC circuit. Excessive uplink power will not make
your signal louder - it will only reduce that available for others on
the transponder. With a clear view of the horizon, 5 watts to an Arrow
or Elk is plenty for horizon to horizon coverage. Very slightly more
might be necessary if you are beaming through trees or other
obstructions, but try to keep power to 25-40 watts ERP.
Good luck! Who will claim the 73 on 73 Award #1?

Hi Bob!
I think this will be a challenge for all of us, wherever we are
on the continent. With VO-52's recent demise, maybe more will
start to try working AO-73. Many (most?) have difficulties when
relying on software to run the radios, and end up trying manual
control to deal with the uplink. It's not hard, but different.
Now we need to get more stations working AO-73, so we have a
shot of working 73 different calls.
73!

Hi!
W1AW/7 will be on FO-29 for the western pass at 0200 UTC,
followed by AO-73 passes at 0400 and 0534 UTC. It looks like
Hawaii should be in the footprint for a few minutes, starting
around 0204 UTC, if anyone out there is interested in getting
on FO-29.
I plan on having W1AW/7 on the air Monday afternoon from the
DM33/DM43 grid boundary for the 1845 and 2027 UTC passes.
The earlier pass around 1705-1713 UTC has maximum elevation
of only 4 degrees, not really a workable pass from the Phoenix
area with the mountains around the city, so I will focus on the
two later passes. After these passes from the grid boundary,
W1AW/7 will be on FO-29 and AO-73 passes in the late afternoon
and early evening to wrap up the W1AW/7 satellite activity from
Arizona as part of the ARRL Centennial QSO Party.
As a reminder, QSL cards for all W1AW/x operations will be handled
by the ARRL. As ARRL receives logs from the W1AW/x operations,
those logs are uploaded to Logbook of the World - including the grid
locator(s) for each QSO. QSOs with W1AW/7 on the AO-73 passes
tonight and tomorrow night also count for N8HM's new 73 on 73 award,
if you are looking to get unique calls in your log.

My first AO-73 pass eligible for the 73on73 Award was exciting. It
reminded me of my "first time" (working sats, that is.)
It was my first time to work the bird with a single Yaesu FT-817 and an
Arrow antenna. No fancy computer, no fancy apps. Just steering the antenna
with one hand and a microphone in the other.

Paul and Clayton,
Not only was it nice to hear all the activity, everyone
was being careful with how much power was being used. I
never heard any FMing or other telltale signs that the
transponder was being overloaded. W1AW/7 was able to
log 3 stations during that pass - AA9LC, AC0RA, AA5PK.
For the night owls on the west coast, or anywhere else
in AO-73's footprint, W1AW/7 will be on the next pass
starting around 0534 UTC.
73!

Hi Perry -- Let be make a guess -- you were relying on the daily digest
of AMSAT-BB messages rather than having all the individual messages come
to you as they are entered. I used the daily digest for my convenience
and I had that service go away a few months ago.
It turns out that minor changes to the mailer were made a few months ago
and the daily digest delivery was an unplanned casualty. However, I
found a similar service is available on the web by going to
http://amsat.org/pipermail/amsat-bb/ where you will find a monthly
digest. What I do is to click on the date sort [ Thread ]

I was on a pass on Saturday and heard one QSO I moved down about 5k and
after finding myself started calling CQ. After 5 minutes or so I worked no
one. I was using SatPC32 and was about 10k away from where I was last time I
used the bird. Once d/l was found the s/w had no problem with the offset.
