Sending Christmas Greetings to the ISS

There was much media coverage in the UK of the "Santa pass" (Telegraph, Daily Mail) The International Space Station passed over the UK in the late afternoon and early evening on Christmas Eve and around 17:20GMT promised an especially bright display in the dark skies. So imaginatively we were asked to observe and imagine that the bright moving point of light was actually Santa off delivering his presents.

As luck would have much of the UK had a crystal clear sky and I even managed to get my 80 plus year old Mother-in-law out in the garden to watch the spectacle. She was impressed and it was great to overhear lots of excited children coming out in the nearby homes to watch Santa as he flew overhead.

Back in October 2013 after becoming a newly licensed radio amateur I managed to send APRS packets to the International Space Station which were digipeated and received back on earth by other operators. Back then I used a lowly Baofeng UV5R handheld and I decided to repeat the exercise this time using the FT857D (this time running around 20W) to talk to Santa!

The computer I used back then has been decommissioned so on the laptop I installed the UISS program from ON6MU which makes easy work of APRS to the ISS and instead of the cumbersome AGWPE I used the excellent soundcard modem from UZ7HO.

I attempted to send a message on the pass at 15:43 but failed completely, discovering I'd got my soundcard incorrectly set up. I corrected this and left the autobeacon mode running in UISS during the Santa pass and checking back much later could clearly see I'd sent and had a message repeated back from the ISS.


Checking the ariss website (www.ariss.net) I could see the repeated message had been received by another station and my position was showing up on the map (M0NRD)

I have successfully done it again today on Christmas Day! As the raw packets below confirm.

M0NRD>CQ,RS0ISS*,qAR,DM2RM:73' Happy Christmas from Andrew IO93OB
M0NRD>CQ,RS0ISS*,qAR,MB7USS:=5304.08N/00048.47W-73' Happy Christmas from Andrew
M0NRD>CQ,RS0ISS*,qAR,HG8GL-6:73' Happy Christmas from Andrew IO93OB


It was a nice achievement and another nice Christmas present was achieved early this morning while running WSPR on 40m, managing to get received in New Zealand


Anyway enjoy the rest of the festive season and I wish you all the best in 2015

APRS Maps

I’ve had a little play about whilst avoiding the household viewing of ‘Strictly come dancing’ aka ‘celebrity showing off’ with the APRS maps you can embed through APRS.fi

I’ve added a little map to the site here

Just a bit of fun but I do like APRS. Great for the fells.

Trouble is it seems to default to Helsinki regardless of the lat / long you put in the script

Baby Steps in the Second Century of Radio

Everyone is talking about where the hobby is going in this “Second Century” of amateur radio and big ideas are falling like rain. Here’s something fairly simple that I’d like to see come to fruition. It should go without saying that these are fictional press releases…

#PRESS RELEASE
January 3, 2015

Chinese electronics manufacturer WunDuko announed today the immediate availability of a new VHF/UHF handheld transceiver for the amateur radio market. The device supports a thousand memory channels with alphanumeric display. The advanced communications device includes low-power Bluetooth communication permitting it to be programmed and upgraded via Bluetooth from a smartphone or personal computer. The handheld is expected to retail for $159 US.

#PRESS RELEASE
January 4, 2015

Internet Labs today announced the availability of a suite of Android applications intended to work with the new dual-band amateur handheld from WunDuko. The software enables Bluetooth communications between a smartphone and the transceiver. One of the apps included provides easy access to the full menu of options in the handheld, including the ability to program the memory channels, via the phone interface.

One of the other apps provided in the suite enables GPS data from a capable smartphone to be transmitted periodically via the handeld transceiver while position data from the radio appears on the phone via Google Maps. A company spokeman said, “it’s the perfect mobile APRS solution. There’s no klutzy hardware interface required between the devices and no reason at all to carry multiple GPS receivers.”

He also noted that the GPS in the smartphone works regardless of having a cellular connection. “Pairing the smartphone that you carry everywhere you go with the new handheld transceiver is the kind of sensible innovation we’ve been waiting on from the Japanese manufacturers for years”.

The Android app suite is available now in the Google Play Store for $9.99 US. Look for it to also be available on iOS in the coming months.

HFI gates QRT

I have taken down my HFAPRS gates. The reason is they all use my MFJ magnetic loop antenna. At this time of the year it needs constant retuning due to temperature variations in the loft. So it is not practical to use it when I can not be in the shack to tweak the turning .

Tracking wildlife

I watching a wildlife programme on TV the other day which had a feature about urban foxes. The naturalists  had fitted radio collars to some of the foxes and were able to track them over a wide area.One fox went off on a trek that lasted a couple of weeks and covered a distance of several kilometres.

In another programme radios have been attached to larger birds such as geese and ospreys to track their migration paths.
I wonder what frequency is used? One of the maturalists in the urban fox project seemed to be trying to DF a fox using what looked auspiciouslylike a 3 element 2m Yagi. I’ve seen similar antennas used o locate larger animals in Africa.

I would love to know what technology they use. My Kenwood TH-D7E APRS radio – despite being too big to use as a tracker for anythimg much smaller than an elephant –  can run for only a few hours with the GPS enbled and the power set to a sufficient level to enable tracking over a reasonable distance.using a less than optimal transmitting ntenna.
