Hi Gus, As I mentioned "I thought to give the list a try before if go the script way" Do you have such a script? Make an input variable with the desired SATS read from input files and output to my own output file that I can use with my favorite tracking software. 73 Jan PE0SAT On 12-03-2013 23:22, Gus wrote: What exactly do you need to do?

[amsat-bb] ISS digital packets
Hello all I have recently been unsuccessful in sending digital packets to the ISS since the change in radios on the station. I use an Elk with my Yaesu VX8DR and the path I use is ARISS. I have recently tried adding a WIDE to that path to see if I could get gated, but have been largely unsuccessful except for one day, but haven't been able to get back on, even with a relatively high pass. Does anybody know if the path has changed since they are now using the Ericsson instead of the Kenwood, or if there are any significant changes I can make?. It could possibly be just the 5 watt HT can't do the job with the Ericsson. Any help appreciated. Thanks in advance. 73, Elizabeth WB3U ___ Sent via AMSAT-BB@amsat.org.

Subject: [amsat-bb] SatPC32 Update for Tone Control of Yaesu FT-857/897
Recently I bought a new Yaesu FT-897D to replace a FT-817ND to give me a
little more xmit power when operating portable, but still using
internal batteries. When I tried to use SO-50 I found that I couldn't get
thru the sat. Back home I traced the problem to the CTCSS tone not
being set in the FT-897D via SatPC32 "T1" & "T2". My FT-817 worked without
a problem.
I contacted Erich Eichmann who quickly sent me a modified version to test.
It worked! Erich will be putting a patch version on his website
shortly: www.dk1tb.de See the English page and then Download page. I
thank Erich for making the change & so quickly - much quicker than
me in sending this to the AMSAT BB!
Detailed Description - for those interested:
The set CTCSS tone frequency is apparently the only CAT command that is
different for the FT-857/897 from the FT-817. The 5-byte
command for the FT-817 contains the tone frequency in bytes #1 & 2, and the
command Opcode "0B" in byte five. Bytes #3 & 4 are only
place holders and are set to ASCII code zero by the SatPC32 program. For
the FT-857/897 bytes #3 & 4 are used to set the receive CTCSS
tone frequency. Apparently even if the receive tone is not being used,
bytes #3 & 4 must contain a valid tone frequency. It looked like with
ASCII code zero in bytes #3 & 4 that the radio would interpret the command
as invalid and never set the Tx tone. There is no clarification of
this in the user manual. Erich has now sent the Tx tone in both the Tx tone
bytes and the Rx tone bytes (byte 1 = byte 3, byte 2 = byte 4).
This appears to correct the problem of tone not being set.
Now in SatPC32, for SO-50, when "T0" is clicked to get "T1", the CTCSS tone
of 67.0 is set in the FT-897 (as seen in Menu Mode 083). When
"T1" is clicked to get "T2" to enable SO-50, the CTCSS tone of 74.4 is set
in the radio (as seen in Menu Mode 083). When "T2" is clicked to get
"T0" for tone OFF, the CTCSS tone encoder is turned off but the tone of 74.4
still remains in Menu Mode 083 even though it is not being used.
So now the CTCSS tone control function in SatPC32 works on the FT-897 (and
should on the FT-857) just like it worked on the FT-817.
The CAT commands on all three radios to turn ON CTCSS encoding is (4A xx xx
xx xx 0A) and to turn OFF is (8A xx xx xx xx 0A). The tone
ON/OFF function always has worked for all three radios. On the FT-897 I
could see "TEN" on the display when the CTCSS tone encoder was
ON either "T1" & "T2" in SatPC32), and then "TEN" would disappear from the
display when the tone encoder was OFF ("T0" in SatPC32).
For testing the transmitted CTCSS tone I found that the "Tone Search
Scanning" function (tone decoder) built into the Yaesu VX-6R HT,
the FT-817ND and the FT-897D, worked well and was just what I needed!
Thanks again to Erich for a great program, his program support & support of
AMSAT!

[amsat-bb] Re: Unix command line Kepler manager
Here is a bash script that might be of help:
8<
#!/bin/bash
CAT=/usr/bin/cat
RM=/usr/bin/rm
WGET=/usr/bin/wget
GREP=/usr/bin/grep
VERBOSE=1
# change these to suit your taste
OUTPUT=${HOME}/MySatellites.tle
MATCH=${HOME}/Sats_I_Like.txt
# delete existing output file
if [ -f ${OUTPUT} ]; then
[[ $%{VERBOSE} ]] && echo "Deleting ${OUTPUT}"
${RM} ${OUTPUT};
fi
# heredoc contains URLs of interest. Edit to suit yourself
[[ $%{VERBOSE} ]] && echo "Fetching elements from www.celestrack.com"
${CAT} << EOF | while read URL
http://www.celestrak.com/NORAD/elements/amateur.txt
http://www.celestrak.com/NORAD/elements/weather.txt
http://www.celestrak.com/NORAD/elements/visual.txt
EOF
do
[[ $%{VERBOSE} ]] && echo "-- ${URL}"
${WGET} -q ${URL} -O - | ${GREP} -A 2 -f ${MATCH} >> ${OUTPUT}
done
[[ $%{VERBOSE} ]] && echo "Done."
>8
This will fetch one or more element files from celestrack (you say which
URLs to use in the heredoc) and pick out satellites of interest to you
by name, combining the results into a single output file. You specify
the satellites you want in a match-file (name defined at the top of the
script) and similarly the name of the file where you want the results put.
Two cautions: 1) be careful with your matches. "AO-7" matches with
"AO-71" too. And 2) if a satellite appears in more than one input file,
it will appear more than once in the output. (Example, ISS (ZARYA)
appears in amateur.txt and visual.txt.)
You could change a few things -- select by satellite number & designator
rather than name, for instance, or read URLs from an external file. Or
have the heredoc also specify the name of the output file for each input
URL. But for anything much fancier than this (like sorting the output
by satellite name, skipping duplicates, anything but the simplest of
command-line arguments, etc) I'd go with a perl script.

Download the elements from celestrack with wget or Perl's
LWP::Simple. Use grep with the --files option to select satellites of

else do you need?
A modest Perl script would go a long way...

Hmmm. I don't know how or why, but all my VERBOSE shell variables seem to have acquired an unnecessary percent sign. The script will still run as-is, but please remove those unwanted %age symbols if you decide to try this script.
