Dear all.
Could you help me please.
do we need TNC with ic910h for reciveing digital signals for example in
ax.25 format from satellites?
Thanks for your help and attention.
Best Regards.
Nayer Mahdinejad.

I have question about ic 910 h.maybe my question is simple,parden me. But
the reason is that I am university student and it is my project to design
amateur satellite ground station and select best hardwares.
Can we use both the main and sub band of ic 910h for receiving signal?
If someone add the ux-910 to ic-910 for 1200MHz band,how it used for 3
bands? vhf, uhf and l-band?
Thanks for your help and attention.

JARL command team announced
Eclipse of FO-29 is 11/01 0% 11/10 5% 11/20 14% 11/30 17%. It goes up
gradually. The temperature of the satellite falls with an increase of
eclipse. It is considered as one of the reason that the temperature of
FO-29's equipment is too high to accept the command. FO-29's equipment
is designed to work for wide temperature range. However because of time
degradation, it is to be considered that some component may have lower
performance. JARL command team sends the command to FO-29 on the every
weekend continuously. We are thinking that FO-29 will accept command
when the temperature of equipment cools down to certain level.

I am having a problem getting the subtone entered into the SatPC32 program for
HO-67 on my FT-847. Going to the sqf file, I have entered the sequence as I
have for the other satellites, making sure the name is spelled correctly, etc.
This is what I have entered:
SUMBANDILA(SO-67),233.6,$3F,1
Dont know why it wont transfer over to the CAT system, as had no problem with
the others... any ideas?? Right now I have to enter it into the radio
manually.

OSCAR-11 REPORT 31 October 2010
This report covers the period from 30 September to 31 October
2010. During this time the satellite has been heard from 09 to
19 October and from 30 October. At the time of writing it is
transmitting and is expected to continue until 09 November.
Excellent signals have been reported from stations located
around the world, and good copy obtained from decoded telemetry
frames.
The satellite is now transmitting during eclipses, although
signals are weaker at those times. This indicates that there is
still some capacity remaining in the battery.
The on-board clock is now very stable. It gained only ten
seconds in 33 days. This is comparable with its accuracy when the
satellite was fully operational, when it gained approximately one
minute per year. However, there is still an accumulated loss of
309 days, which has occurred during eclipses of the last few
years.
Operation during eclipses and stability of the on-board clock
suggest that some part of the system may have recently failed
'open circuit' thus reducing the overall power drain of the
system, and allowing more power to be available during eclipses.
There was an unexplained current drain observed when analogue
telemetry was last transmitted. This fault might have cleared.
The Beacon frequencies are -
VHF 145.826 MHz. AFSK FM ASCII Telemetry
UHF 435.025 MHz. OFF
S-band 2401.5 MHz. OFF
Reception reports have been received from Jeff N3QO, Rod CX2ABP
and Ian KI4HLV/6Y5 (G4JMM) . Many thanks for those and to
everyone who posted reports on the satellite status website. This
is a very convenient and easy to use facility, which shows the
current status of all the amateur satellites. Strongly
recommended for future reports! Reports around the expected times
of switch-on and switch-off are of special interest. The URL is
http://oscar.dcarr.org/index.php
OSCAR-11 transmits on 145.826 MHz., set receiver to NBFM. The
satellite has a characteristic sound, rather like raspy slow
morse code, sending "di di dah dah dah dah dah dah dah" sent over
a period of five seconds. If you are receiving a very weak
signal, switch the receiver to CW or SSB. You should hear several
sidebands around the carrier frequency and should be able to hear
the characteristic 'morse code like' sound on at least one
sideband.
Please note that you need a clean noise-free signal to decode
the signals, and your receiver must be set to NBFM mode, for a
decoder to work.
If you need to know what OSCAR-11 sounds like, there is an audio
clip on my website www.g3cwv.co.uk/ which may be useful for
identification and as a test signal for decoding.
The current status of the satellite, is that all the analogue
telemetry channels, 0 to 59 are zero, ie they have failed. The
status channels 60 to 67 are still working. The real time clock
is showing a large accumulated error, but is now incrementing
accurately to within a few seconds per month. The day of the
month has a bit stuck at 'one' so the day of the month may show
an error of +40 days for some dates. The time display has
switched into 12 hour mode. Unfortunately, there is no AM/PM
indicator, since the time display format was designed for 24 hour
mode.
The spacecraft computer and active attitude control system have
switched OFF, ie. the satellite' attitude is controlled only by
the passive gravity boom gradient, and the satellite is free to
spin at any speed.
The watchdog timer operates on a 20 day cycle. The ON/OFF times
have tended to be very consistent. The average of many
observations have shown this to be 20.7 days, ie. 10.3 day s ON
followed by 10.4 days OFF.
Listeners to OSCAR-11 may be interested in visiting my website.
If you need to know what OSCAR-11 should sound like, there is a
short audio clip for you to hear. The last telemetry received
from the satellite is available for download. The website
contains an archive of news & telemetry data which is updated
from time to time. It also contains details about using a
soundcard or hardware demodulators for data capture. There is
software for capturing data, and decoding ASCII telemetry. The
URL is www.g3cwv.co.uk .
If you place this bulletin on a terrestrial packet network,
please use the bulletin identifier $BID:U2RPT150.CWV, to prevent
duplication.
