Hi all,
We had a northerly pass of SO-50 earlier today and I was unable to switch
the timer on, get any response, or hear anyone else.
I used the 74.4 Hz sub tone to arm the timer but nothing. I have 100 Watts
available to steerable beams, so signal strength is not the issue.
Is this bird difficult to open?
Thanks
Peter

Have you used SO-50 before? It's not always easy to hear, even with large
beams. However, it hears excellently. Before the 74.4 command was made
public, I used to enable it automatically with a 2 watt HT and packet beacon
every 3 minutes, to an omni.

Hi Ken,
Hope this helps:
The output below certainly appears to be AX.25 in KISS format with the
extended
ASCII characters translated to perhaps something like Windows Arial font.
The a-grave (the "A" with the backwards accent) is hex C0, which is the
KISS frame delimiter
that appears at the start and end of each KISS packet. There are two of
them after "UTC"
indicating that the first frame is the date/time in UTC. There is
another one at the end
after "test".
The second frame contains extended ASCII characters similar to the way
callsigns appear
in AX.25. The hex values for these (from the second a-grave after UTC
through to just
before "This") appears to be
9E A6 86 6A 68 6C DB DC 8E A6 B0 6E 68 72 20 03 F0
[footnote 1] (assuming that all of the characters made it through the
mailing list
intact and correct, which I'm not sure they did)
From this byte sequence, "DB DC" is a KISS byte sequence for Frame
Escape (DB),
Transposed Frame End (DC) which means that the over-the-air byte was
actually a hex C0. [ footnote 2]
Substituting "C0" for "DB DC" This gives us the hex sequence
9E A6 86 6A 68 6C C0 8E A6 B0 6E 68 72 20 03 F0
If we assumed these bytes represented callsigns and right shift each
byte in the same way
that we would for AX.25 callsigns, then we get the byte sequence
4F 53 43 35 34 36 then "C0" then 47 53 58 37 34 39 then "10" then "03"
then "F0"
and translating just the "callsigns" back to ASCII we get
O S C 5 4 6 "C0" G S X 7 4 9 "10" "03" "F0"
and then treating this like an AX.25 frame we would end up with "C0" and
"10" as
SSID values "0" and "8" per the CRRSSID0 format. This gives us the
callsigns
OSC546 with SSID 0 as the destination callsign and GSX749-8 as the
transmitting
station. Not valid amateur radio callsigns, but...
"03" would be the AX.25 control byte corresponding to "Unnumbered Frame"
(U frame) [footnote 4]
and
"F0" is the protocol identifier byte (PID) indicating that there is no
layer 3 protocol
implemented. [footnote 5]
Depending on your TNC model, the output from a TNC in non-KISS mode would
look something like this:
2014-01-21 17:56:35.490 UTC
GSX749-8*>OSC546:<UI>:This is another Trailblazer Repeater test
Hope this helps.

footnotes:
[1] Hex dump from Ken's email, but this might not be correct if the
extended
ASCII characters were corrupted by the mailing list. In particular the
first
letter of each callsign might be some other value. Also, since I did all
of this by hand, there a chance I made mistakes. The actual hex dump of
the received packet would be much more conclusive.

Does the really nice Ten Tec powder coated enclosure being sold by AMSAT
have and opening for the USB port? I am finally getting around to building
the board and USB adapter that I have.

Hello everyone this is my first postage so please be gentle !
I am looking for the Kepler elements for LITSAT-1.
Have looked on Amsat UK website but can't seem to find anything.
Can anyone help please.

I don't think it has been deployed from the ISS yet, so there are not any.
Once deployed I'm sure they will be published.

Hi Andy,
I don't know when the deployment of LITSAT-1 and LituanicaSat-1 is planned
for but when it occurs the Keps will initially be similar to those of the
Space Station. So if you just use the ISS Keps that will be good enough.
