This evening I tried working amateur satellites again. There was a nice ISS pass at 18:19 UTC and this time it was very easy to aim the antenna since the ISS was still illuminated by the sun so it was a bright spot in the sky. But no astronaut responded to my CQ call, not even when I remarked "I can see you!".

I also looked up some more satellites that are one-way and this included the HO-68 amateur satellite. It transmits a CW (morse code) beacon and I tried to receive and decode it. Receiving works, but I can't decode morse by ear and fldigi tries but it doesn't look like valid HO-68 telemetry format as documented in the HO-68 page above.

Update 2014-10-22: I asked PA5ABW, a very experienced CW operator to listen to the recorded audio and he helped decode the transmission above into:
And noted the groups of three letters can also be 'shortened digits' and decode to:
BJ1SA XW XW 111 000 121 100 000 000 000 000 000 000 000 000 XW XW
which as a telemetry report decodes to:
 CH1 PA Output RF Switch status: 111 PA2 works (beacon only)
 CH2 Transponder working status: 000 Beacon only
 CH3 Transponder temperature:    121 = +21 degrees
 CH4 Beacon RF Output Power:     100 = 100 mW
 CH5 and further: 000

Google+Koos van den Hout : A fun week in information security:
- Affected accounts are published from the 'Hold Security' dataset
- A heavy patch tuesday (note IE in there)
- Oracle critical patches
- Poodle SSLv3 vulnerability
and I'm probably missing a few 'interesting' things.

Een creatieve leugen in de spam vandaag:
Je bent lid van deze mailing list omdat U ingelogd bent geweest bij Du Cap SoWifi.
Blijkbaar vraagt die wifi toegang om een e-mail adres en iemand heeft daar een adres van mij opgegeven, en krijg ik dus maar de rommel.

Interesting spam on a role-account at work from biorbyt. According to Biorbyt - Spam for science - BioSPAM they will spam addresses from scientific papers. According to their privacy policy they will not spam:
Biorbyt will not send you email that you have not agreed to receive.
but I have a hard time believing that when I get their mail on a role account related to security, absolutely not interested in
Leukemia markers optimized with FIX&PERM® flow cytometry reagent Introducing our new range of FIX&PERM® for flow cytometry and validated, CE certified leukemia markers which allows for mild, fast and simultaneous staining of both intracellular and cell surface markers.
Showing mainly that the business model of spam is that spamming 100.000 accounts for one sale is a perfectly viable business model when you're not encumbered by any ethics.

2014-10-10 (I made a recording of a pass of the SO-50 amateur satellite over Europe on 26 September 2014. I noticed...) 2 weeks ago
Google+Koos van den Hout : I made a recording of a pass of the SO-50 amateur satellite over Europe on 26 September 2014.
I noticed good operating procedures and a high number of completed QSO's. It almost sounded like some locator contest was going on.
When I compare this with the 'zoo' I heard in July, with CQ calls heard without any callsign... it is possible to have good operating procedures!
2014-10-09 (#) 2 weeks ago
Still in the archives: another SO-50 pass recorded at 26 September 2014. Again good operating procedures, maybe some sort of locator contest was going on, since I heard several exchanges with in one go callsigns and locators. Callsigns heard: SV2KGA, S54LD, CT2GOY, S52LD, 9A3ST, SQ8RK, IW3RGK. And yes my definition of 'heard' includes listening to the announcements in the recording over and over, I did not understand them all when it happened.

Ik kijk even rond in het centrum van Uithuizermeeden op google streetview en ineens valt me een antenne op die wel erg lijkt op een antenne voor VHF II (FM omroepband) gebruik op een tijdelijke mast. Alleen staat er volgens het antenneregister helemaal niets op die plek, alleen een zendamateur aan de overkant van de straat. Het was vast een tijdelijke opstelling die ondertussen weg is.

This is really old-school: I see messages in the newsmaster mail from a newgroup/rmgroup war. Haven't seen that in decades!
god@heaven.com asks for christian.binaries.sermons
to be created.

If this is acceptable, type:
  /usr/lib/news/bin/ctlinnd newgroup christian.binaries.sermons y god@heaven.com

And do not forget to update the corresponding description in your
/var/lib/news/newsgroups file.

The control message follows:


For your newsgroups file:
christian.binaries.sermons      Christian sermons

CHARTER: christian.binaries.sermons is a newsgroup for Christian

The newsgroup and hierarchy will not be strictly moderated per se. Spam
and heavy trolling is not permitted, however, and may be post-moderated
after the fact. The christian top-level hierarchy does not follow the
precise policies of the current free.* hierarchy. We do, however, share
a similar vision of a relatively free and open hierarchy allowing almost
anything created by virtually anyone, with few rules.

JUSTIFICATION: Christianity being one of the world's largest religions,
there are several Christian newsgroups in various hierarchies out there,
but no established central structure that combines a variety of topics,
and especially Christian binaries are fragmented in disjointed
hierarchies throughout the Usenet. This newsgroup under the free.*
mantle espouses the ideas of freedom, the liberty to create your own
group, and allow relatively free posting with the exception of spam and
heavy trolling. As Christian newsgroups are often trolled, this is a
necessary evil for the hierarchy to thrive. In this new age of
persecution and ostracization, the christian hierarchy is necessary to
unite Christians worldwide and give them a digital home.

There has been much discussion on the Usenet regarding the need for
separate Christian groups, especially topic -specified binaries groups,
which seem to be largely absent in terms of Christian media. The amount
of Christian material found in any typical web search on this subject
alone is sufficient justification for this group.
I'm not sure usenet binaries are the best way to reach christians today. The church I visit uses live-streaming with availability on a mobile 'app' and the archive is available via the church website.

2014-10-05 (I enjoy psk31 on 10 meters. The choice of band is simply because that is what size dipole I could fit...) 2 weeks ago
Google+Koos van den Hout : I enjoy psk31 on 10 meters. The choice of band is simply because that is what size dipole I could fit under the roof easily. The 10 meter band isn't always open so it is a bit of hit and miss but I have had nice openings allowing me to have contacts with Greece, Italy, USA, Slovenia, Romania and other countries. I have seen signals from Brazil and South Africa but never managed a full QSO.
In the previous weekend there was clearly an RTTY contest going on, but switching to that mode in fldigi and answering a few CQ TEST calls also worked for me. I uploaded the log: I'm not in it for the contesting but I do want the contesters to get their QSOs validated.

It seems the Garmin GPS 18 LVC for timekeeping in the ntp server on ritchie.idefix.net is having weird issues. It stops responding with the carrier high and sometimes restarts.
On such a 'hang' the carrier detect is high. Weird problem.

No contacts, but some other firsts in radio amateur satellites for me yesterday evening. Using the digimode interface for the Yaesu FT-857 radio I recorded a pass of SO-50 in FM mode and a pass of AO-73 (Funcube-1) in SSB mode. And I was able to understand at least one callsign in the AO-73 downlink, which is also a first for me!

SO-50 Saudisat 1c recording at JO22nc, 2014-09-25 20:30 UTC. Callsigns heard: S56SG, DF9GH, DL2EEL, DO5BK, IW3RGK.
Most of these callsigns I can only decode now with having the option of listening to the recording again and again.

AO-73 Funcube-1 recording at JO22nc, 2014-09-25 20:50 UTC. Only one callsign heard while tuning through the downlink band: DG1EA but I heard the call clearly enough to understand it right away. A first for me.

This week I seem to have a thing for completely missing or being unable to make use of good propagation conditions on the 10 meter band. I do use the WebSDR at Utwente to check the band. Yesterday I noticed some activity, including a Lebanese radio amateur who was very popular. Lebanon does not have a lot of active radio amateurs and other radio amateurs want to have contacts with as much countries as possible, including 'rare' ones.

I also heard some unlicensed transmitting music. With the 10 meter amateur band being in frequencies above the '27 MHz CB' band there is some 'export-only' equipment that can do both and unlicensed use of the 10 meter amateur band happens quite regularly.

Maybe I want to upgrade the HF antenna experiment to also work on the 20 meter amateur band. Working long distance (DX) is usually a lot easier on 20 meter, especially at night. There is a nice video about making contacts on 20 meter at night: The Fun Of Ham Radio DX - Making Friends Around The Globe - RadioHamGuy on Youtube.
