The K3S must be working alright on 475kHz!

Having done the K3S upgrades for 475kHz see here it was time for DX.  I was duly rewarded with my First transatlantic WSPR decodes of the year using the K3S and the PA0RDT whip in the loft:-

Strange conditions on 10m WSPR Saturday 26 April

While doing some other tasks on Saturday I let my Ultimate 3 transmitter run for the whole day from 1200z at 1W output with the help of an external PA. The results were very strange. Nothing, then lots of Oceania with a few Americans at the start:-

10m WSPR for an afternoon

As I had not tried to Use the Alexloop on 10m I thought today would be a good opportunity. I left the anan-10 running at 0.5W output while working on other projects and was impressed by the results:-

A night on LF

Having repaired the wind damage to my WA1ZMS loop I thought I would take a listen around 500kHz

Using the loop to the Anan-10 with W5WC mrx software and wspr from K1JT I could see some local signals on wspr and the multimode signals (cw and psk) from WD2XSH/7 in LA. I quickly decoded the local signals as  WG2XXM (a new state for me OK!)  and WG2XIQ.

I then decided to hook up the anan headphone output to the Nexus 7 and see if Droidpsk could decode the PSK signal (while still decoding WSPR on the PC)



WD2XSH/7 is the signal in the green box. WG2XIQ is the signal at the 5 marker, WG2XXM is the signal slightly hf of WG2XIQ. You can see they are timed WSPR signals (but not decode them on android!)

I left it running for a while and started to see two more signals, WD2XSH/12 in CO (DM79) at 1092km and the best (WSPR) dx WG2XJM in EN91 at 1746km

I then had a listen on cw and heard WD2XSH/31 in VA again at 1651km   Signals faded out at 1236z, WD2XSH/12 in CO was the last signal seen

Not bad for an 8 turn loop!

Ubuntu on the Beaglebone Black (1)

After spending the afternoon over in Fort Worth doing a presentation on the 1.3GHz UK Activity Contest to NTMS, this evening was spent installing Ubuntu on the BBB

Initially I tried the procedure using a prebuilt image  at http://www.armhf.com/index.php/boards/beaglebone-black/ and eventually, after solving some issues due to priveleges I got a USDHC card produced. Unfortunately, after powering up the BBB with the reset button near the uSDHC pressed as instructed and waiting, it produced lots of flashing blue lights but no video output. Time to try something else.

Next I searched for any other prebuilt images and came across http://elinux.org/BeagleBoardUbuntu#Raring_13.04_armhf (a later version of Ubuntu) I followed the instructions on my ubuntu laptop which did not need any corrections and built an uSDHC card

Booting the BBB with the reset button pressed it was reassuring to see a penguin appearing on the screen and a demand for login and password

Flushed with success, I decided to try and install WSPR. I used the process of the previous WSPR http://g4fre.blogspot.com/2013/01/wspr-on-rpilapdock-under-raspian.html blog. However all commands had to be typed in letter by letter, as, not having a desktop or browser I couldnt go to this blog and cut and paste!) It built way faster than it ever did on the RPI.

Launching WSPR it complained as usual about having no display to export to, so the next step is to install a desktop, find a sound card (and a browser!)

40m WSPR on Valentines night


I thought for a change I would run the FT817 on wspr overnight on 40m and see where it could be seen. Im pressive results,  especially DU1MGA for a new country on this mode

WSPR on the MK808 under Picuntu...Not Recommended

Time to try WSPR on the MK808 under Picuntu. Using the same method as previously used it installed without issue. I plugged in the IMIC and let it run on 20m

First thing I noted was that the waterfall display was flickering and alternating between two completely different displays. The second thing I noticed was that the "sound card calibration values" at the bottom left of the screen were not at their normal 1.00 ish but were at around 0.5. Not surprisingly I got no decodes. I tried adjusting a whole load of settings but still no decodes. I tried the IMIC under Ubuntu and it worked fine. Time to move on to other projects.

The other issue with Picuntu is its screen resolution. It ONLY supports 1080P mode so if you have an HDMI display with any other resolution it looks terrible, text looks particularily badly defocussed. Especially bad was.the display when I hooked the MK808 up to the Lapdocks HDMI input.

Until things improve, (I hear RC3.0 is on the way) WSPR on the MK808 is  not recommended!

WSPR on the RPI/Lapdock under Raspian Revisited


Having got the Lapdock working I decided to install the latest debian package and reinstall WSPR

2012-12-16-wheezy-raspbian so that was downloaded and installed. At installation time I took the opportunity to overclock the board at 1GHz and in the same menu allow the memory space to fill ALL the memory card (if you dont,  you only have 2GB to use, even on a 16GB card!


sudo apt-get update

sudo apt-get install build-essential subversion python2.7-dev python-numpy python-imaging-tk python-pmw libportaudio2 portaudio19-dev libsamplerate0-dev gfortran cl-fftw3 python-dev libhamlib-utils
svn co http://svn.berlios.de/svnroot/repos/wsjt/branches/wspr -r2840

(trying to load the current revision ie omitting "-r2840" software wouldnt build)
cd wspr
./configure --with-portaudio-include-dir=/usr/include --with-portaudio-lib-dir=/usr/lib/arm-linux-gnueabihf

At this point the Makefile that configure created needs to be edited so the RPI uses the hardware floating point processor

vi Makefile (edit wouldnt work on my machine on this file)
make sure line 5 reads:-
FFLAGS = -g -O2 -fno-range-check -ffixed-line-length-none -Wall -Wno-character-truncation -Wno-conversion -Wtabs -fPIC -mfloat-abi=hard

make sure line 9 reads:-
CFLAGS = -Wall -O0 -g -Wall -O0 -g -mfloat-abi=hard



sudo make install 

to launch wspr

./wspr

Again i used the imic as the audio input/output

EU 477kHz WSPR on a non optimum antenna

I had a brief  listen on new years day on the new 477kHz band and heard M0BMU, G0MRF, on cw  but last night I decided to see what else i could find

I hooked up my Anan10 to Powersdr, set the dial to 474.2kHz USB and launched the WSPR programme and let it run. The antenna was my indoor DX-EE 40/20/50/10m dipole

The first couple of decodes took me by surprise:-

2013-01-03 22:14  DF2JP  0.475628  -27  0  JO31jg  0.5  G4FRE  IO82uc  633  282
2013-01-03 22:14  PA3FNY  0.475636  -27  0  JO22nc  0.2  G4FRE  IO82uc  506  273

Leaving it running for another hour the following new stations were identified:-

2013-01-03 23:24  G4HJW  0.475700  -22  0  JO02de  0.5  G4FRE  IO82uc  177  268

PA0A was still there this morning:-

 2013-01-04 09:28  PA0A  0.475700  -25  0  JO33de  2  G4FRE  IO82uc  591  262

Time to think about a real antenna for reception.

HPSDR on 70MHz WSPR again

Overnight I remembered that it is possible to control the HPSDR under Cat control. It can emulate the TS-2000. So I went into HPSDR setup and changed Cat control to 4800-N-2 on COM17  and enabled it:-


In the WSPR program under station parameters PTT method was changed to CAT, enable cat was ticked and Kenwood TS-2000 4800-8-N-2, no handshake chosen:-


Remember N8VB VCOM previously set up a virtual com cable between com7 and com17
Now the HPSDR is controlled without DTR etc. WSJT can also control the frequency.
Efforts were rewarded. My signals were heard in Holland:-

HPSDR on 70MHz WSPR

Tonight I decided it was time to work out how to interface the HPSDR to the K1JT WSPR programme and try it on 70MHz. My Penelope board has a -20dB coupler on the output giving 0dBm which is fine for driving my DEMI L70-28 transverter http://downeastmicrowave.com/PDF/VHF-UHFXVERT_pd.pdf (serial number 1!) to 35W maximum. The normal 0.5W output of the Penny board should be terminated in 50 ohms to protect the output stage

I use the W5WC dual RX version of POWERSDR as this allows me two 96kHz chunks of the band to be seen at the same time. Usually one is on the beacons and one is on the calling channel
First I installed my paid for copy of Virtual audio cable which will allow the audio to be connected between the 2 programmes. It was configured to support VAC1 and VAC2.
Next a copy of N8VB's VCOM programme was installed with 2 pairs of cables, COM6>COM16 and COM 7>COM17
In the HPSDR Setup, CAT control TAB the port is set to COM 16, RTS and enabled:-  


Next the VAC setup in HPSDR. VAC1 is setup as VAC2 as the input and VAC1 as the output:-

Next the WSPR programme needed setting. Audio IN is set to VAC1 and audio OUT is set to VAC2. Note these settings are the REVERSE of the HPSDR ones


Drive level to the transverter was set to produce 5W output. The 10MHz reference for the HPSDR was produced by a Thunderbolt GPS unit,  which also, with the help of KE5FX "Lady Heather" Monitoring programme http://www.ke5fx.com/heather/readme.htm was used to set the computer clock every 15 minutes. The 70/28MHz transverter Local Oscillator is not yet GPS locked; an upcoming project based on the G4HUP DFS design

The system was allowed to run whilst packing the Christmas Candy

Looking at the WSPRNET spot database http://wsprnet.org/drupal/wsprnet/spots it was pleasing to see the signal had been seen:-

 2012-12-22 22:16  G4FRE  70.092565  -15  0  IO82uc  5  M0NKA  IO92  95  63 
 2012-12-22 22:16  G4FRE  70.092534  -22  -1  IO82uc  5  PA0TBR  JO22pi  517  84


The PA0BTR spot was the ODX for the days spots on 4m; not bad for my Indoor Halo!

Digital modes at Thanksgiving

Being Thanksgiving today time for some radio. I dusted off my ARDMEPT trannsmitter which is capable of multiband WSPR and QRSS running 250mW. Having the HF6V multiband Vertical switching antennas between bands was not an issue
I loaded the code for QRSS on 30m  30m WSPR and 10m WSPR. The results were interesting:-

10m WSPR
One station in England (G4HZW), two in Australia (VK7BO, VK2ZMT),  the rest in North America

30m WSPR
One station in Venezuela, the rest in North America

 Due to issues with grabbers hosted on QSL.net I used the new grabber in New mexico at http://qrss.nmsu.edu/SPOTD-30M.html

30m WSPR received in New Mexico
