WSPRing on 10m with W5OLF’s latest transmitter

I managed to find time to assemble my 10m WSPR transmitter yesterday and put it on the air this evening. This is the 3rd version of such transmitters from Jay and it is significantly different than previous versions. For starters, it transmits 100% of the time and changes frequency semi-randomly from one 2-minute TX cycle…

472kHz WSPR

All day I have been on 472kHz WSPR and on 10m WSPR since mid-morning. Since mid-afternoon G8LCO (58km) has spotted my 5mW ERP several time. Last night at 0220z I was spotted by F1AFJ (607km). I think this is the second furthermost report of my 5mW ERP with the earth-electrode "antenna".  At some point I really must work out how many unique 472kHz WSPR spots I have had at this QTH. My best DX is over 1000km when I was spotted in Norway.

Last USA spot today of my 500mW on 10m?

At the current time, 1910z,  WA0APC (7012km) was the last to spot my 500mW WSPR on 10m at 1650z. Since then, just Europeans spotting me. It is still just about possible that other USA stations might copy me, although it has been dark here now for 3 hours, so I'd be surprised.

The reports from Germany were very strong, so possibly this was winter Es?

UPDATE 2046z:  K9AN (6505km) was the last USA station to spot me on 10m today at 1828z. The last international spots of me on 10m were DK0UG (+1dB S/N) and DK0SC (-11dB S/N) at 1912z. Since then,  just local G4IKZ (18km) spotting my 500mW on 10m WSPR.

UPDATE 2230z: Went QRT on 10m WSPR.

Antarctica yet again and, of course, the USA

At 1216z I see that my 500mW 10m WSPR beacon was spotted in the Russian base in Antarctica again by RI1ANR (13676km) at -21dB S/N.

My first spot from the USA today was KE6BID (5295km) at 1220z.

UPDATE 1406z: RI1ANR has spotted me 8 times already today so far. From here, the Russian base is almost due south.

UPDATE 1506z:  Propagation on 10m to Antarctica seems to have closed (or RI1ANR is in bed!) as no further spots received in the last 1 hour. He is still shown as being active according to WSPRnet.

UPDATE 1536z:   Plenty of reports again of my little 500mW 10m WSPR beacon today so far.
Unique 10m WSPR spots today so far - 500mW
UPDATE 1656z:    AB4QS (7087km) is currently the best DX in North America. Clearly, the Russian Antarctic base is much further.

W5OLF website

W5OLF's tiny WSPR-AXE-CW
Jay, W5OLF, the creator of the "no PC needed" WSPR-AXE-CW beacons for WSPR on 30m, 20m or 10m has just started a new website.  He expects to start selling the new versions of his little beacons, either as kits or built and tested units, in late January. These stay on all the time (the PA can be turned iff) , but frequency is randomised over 100Hz within the WSPR window. Once set, the timing is fine for ages and ages - certainly days or even weeks.

Jay's email (replace the (at) with @ ) is: w5olf(at)comcast.net .

His new website is www.w5olf.com .

I am privileged to be a beta tester of his 10m version (500mW). As you will have read in earlier posts, this unit certainly works very well, mine having been copied all over the planet in just a few weeks. Just press a button to sync time on an even minute and watch all the reports come flooding in. I was blown away with mine. Tiny, but brilliant. If you like WSPR I can thoroughly recommend this little unit. It comes pre-programmed with callsign, locator and power level.

UPDATE 1448z: This little unit has been spotted in Antarctica (13676km) 8 times today already. My antenna is nothing special, just a low 3 band end-fed wire.

Direct conversion ICs - CMX994

Since my days in mobile radio (now nearly 7 years ago) things have moved on.   CML now sell a VHF/UHF direct conversion IC covering 50-940MHz. See http://www.cmlmicro.com/Products/CMX_994_RF_Direct_Conversion_Receiver/?gclid=COrc7qiJ0sICFdLItAodLxEAuA . I wonder if any enterprising radio amateurs have used these yet? I have a feeling the package (ideal for SMA but not for home use) may inhibit its use in amateur projects?

Sunspots and 10m today

Sunspot number is 168 (good) and 10m daytime propagation is expected to be "good". It should be a good day on 10m for F2 propagation  today. I have still to turn on my little 10m beacon - we are a bit late today!

10m - 500mW WSPR beacon spotted by ZS6A and 4L1QX

Best DX this afternoon with the 500mW WSPR beacon is ZS6A (9195km) at 1540z. My report was -22dB S/N, suggesting 100mW may have been enough. There are lot of USA stations spotting me but none from South America so far.

UPDATE 1735z:  Was spotted early this afternoon in Batumi, Georgia (on the Black Sea coast) by 4L1QX (3299km). No great distance, but my first spot from Georgia I think.

UPDATE 1742z:  The last transatlantic (USA/Canada) WSPR spot of my 500mW beacon was nearly an hour ago by KD6RF (7547km). This looks like being the last stateside spot today at 1656z. As he was an hour after the other last spot, this may not be the very latest. I shall have to wait and see.

UPDATE 1820z:  Still lots of USA spots coming through. The evening is young yet.

UPDATE 2220z:   As the band has now closed for DX, I have gone QRT on 10m WSPR. My PC (used for 472kHz WSPR with the FT817) decided to close WSPR4 around 1610z and I have just restarted it. I am now getting and giving WSPR spots on MF again.

Russian ARISS team members activated SSTV from the International Space Station

Today the Russian ARISS team members activated SSTV from the International Space Station, using the replacement Kenwood D710 transceiver located in the Russian Service Module, which has an output of around 5w which was more than enough for receiving stunning images from the station.

15:59z on the 18/12/2014 SSTV image from the ISS

Transmissions started at 14:00z but due to other commitments I missed that pass however picked up the next one at 16:00z using the ICOM IC-910, Wimo X-Quad (2m) with a G-5500 rotator at 16ft and MMSSTV for decoding – I was decoding stunning PD180 images at times the signal was S9+20db without preamps.

The next pass at 17:34z again produced nice images although with some fading however received two images the latter being received down to 1 degree elevation and the signal was still S3-5 with some fading till I completely lost it.

The final image of the day was received at 20:49z which concluded the the days worth of SSTV pictures from space, it was great to see something different from the ISS and I certainly enjoyed chasing each pass.

472kHz WSPR - daytime

Currently I am spotting PA0O (440km), PA3ABK/2 (306km) and G8VDQ (93km) and I am being spotted by G0LRD (25km) all on 472kHz WSPR in daylight using my earth-electrode antenna and 5mW ERP on TX.

Sunspots and 10m

Today's sunspot number is a respectable 154 and 10m propagation is expected to be "good". Already, my 500mW 10m WSPR-AXE-CW beacon (from Jay,W5OLF) is being spotted around Europe, but no further as yet. Best DX report this morning is UR/SWL56 at 2283km. I expect 10m to open to the USA and Canada very shortly.

From today here, the evenings start to get a little lighter again - the change is about a minute a day at first - although mornings get darker until early January. It remains to be seen if 10m stays open slightly longer in the early evenings.

I much prefer lighter evenings!

UPDATE 1232z:  The first USA spot of the day was at 1220z from WG2Z (5600km).

Robert N7XR/VQ9XR comenta:
Un pirata ha estado utilizando mi indicativo en 17mts/Rtty, mientras yo operaba en otra banda. Si no estás en el log probablemente te hayan engañado.

NOTA:
El log online en Clublog de Robert como VQ9XR se ha reducido a 138 contactos cuando tenía varios miles. Esperemos que se resuelva el problema para poder comprobar los contactos antes de enviar las Qsl y ver que no hemos sido engañados.

6m overnight - nothing at all!

Despite being spot on frequency and time last night, I spotted no-one and no-one spotted me on 6m WSPR, which was disappointing.

I have now QSYed to 472kHz where despite just 5mW ERP and using earth-electrodes as my "antenna" I am spotting others and being spotted myself.

I really should give up on 6m WSPR at this time of the year, as it is a dead loss.

Last 10m WSPR USA spot today

KE6BID (5295km) was the last USA station to spot my 500mW 10m beacon today at 1716z. It seems the band, which has been open every afternoon for months now to the USA, is closing earlier as the days get shorter. In the spring it will be a battle between falling sunspots and lengthening days. I suspect we'll still have decent 10m propagation for a year or so yet. By 2016 though, the best chances of USA stations will be by multi-hop Es in May, June and July. I could be very wrong.
