Här kommer lite samlade nyheter om SO-67 från div. källor:
För info, från AMSAT-OZ listan.
Någon i SM som hört den?

[Amsat-oz-bb] Sumbandilasat test 17 november
Sumbandilasat, SO-67 hørt og
kørt for første gang.
Her den 7. november kl. 0817 til 0826 UTC havde de
sat den til at være aktiv over Europa.
Selve passagen var med AOS kl.
0815 og LOS 0826 UTC her hos mig. Det var mod øst med maksimum elevation på
46 grader, så den kom tæt på.
Deres egen vejledning for SO-67
er:
The CTCSS tone for the transponder is 233.6 Hz.
Uplink:
145.875MHz
Downlink: 435.345MHz
Additional recommendations:
Use
only narrow FM
Switch off compression
Speak softly (mic gain
down)
Satellite characteristics:
All antennas are linear vertically
polarized (1/4 wavelength)
Sat Tx power = 5W
Sat Rx sensitivity =
-116.5dBm for 12dB SINAD
Max antenna gain = 4dBi
Note that the
satellite is currently in a controlled sun tracking mode with antennas Nadir
pointing.
Det skal ubetinget tages alvorligt. Jeg brugte FMN på uplinken
og havde oven i købet skruet ned for mikrofonforstærkningen. En del
stationer kørte med normal (gammel) standard frekvens-deviation. Det
bevirker, at downlinken i bedste fald er forvrænget – i værste fald at den
falder helt ud.
Hvis du ikke har FMN (Narrow) på din radio, så skal du skrue
meget ned for mikrofonforstærk-ningen og lade være med at råbe.
Jeg
havde CTCSS tonen på under hele passagen.
Den kom heldigvis fra nord, så
der var tid til at prøve den uden alt for
meget QRM i starten Det blev til
to godkendte QSO’er med henholdsvis G3VZV, Graham, og IZ1ERR, Piero samt en
ikke fuldført med ES8SW, Heldur. Det syntes jeg var nok. Der var mange på, så
de skulle også have en chance.
Indtil videre er den kun i gang, når de
sætter den til det. Det har ikke
været så ofte, så man skal holde øje med
amsat-bb og/eller kikke på:
Oplysningerne kommer ofte med
kort varsel.

To All RADIO AMATEURS
BID: $ANS-312.04
South African amateur radio operators testing on the Sumbandila
SO-67 satellite have reported receiving very strong downlink
signals. Occasionally the satellite beacon was not copied but
the parrot repeater and transponder were operational. The SO-67
operations team posted these hints for operation:
The CTCSS tone for the transponder is 233.6 Hz.
Uplink: 145.875MHz
Downlink: 435.345MHz
Additional recommendations:
Use only narrow FM
Switch off compression

Hejsa,
De har planlagt en masse aktivitet over det meste af Jorden.
Jeg har kun medtaget det, der er af interesse for os:
It will be a busy weekend on SO-67 as we intend to schedule the FM V/U
cross-band repeater on Sumbandila as listed below (all times in UTC;
all activations 15 minutes duration). We appreciate all feedback,
which you’re welcome to post on AMSAT-BB, or alternatively on the
Sumbandila Google Group (http://groups.google.com/group/sumbandila).
For progress made during commissioning of the satellite, please see

Apologies again for the late notification, but we’re still in the
commissioning phase and can therefore not guarantee the SA-AMSAT
payload service far ahead in time.
