Moved over to 10 meters this afternoon. Feeding the 40 delta loop. Hopefully, I will not get arrested.
The U3 did not react well to 12V operation, silly me! Now I have repalced the PIC and the DDS and it works again and I run the unit through a 9-36V down to 5V isolated converter. No earthloop difficulties!
Will continue making improvements.
Moving down the power to around 65mW. Well, truth be told - < 70mW, but more than 50mW.
Trying some WSPR with 10mW tonight on 80m. TRX=FT817 Ant=80m square horizontal loop 7m agl.

I've dropped the power from 250 to 125 mW. Still operating off the 30 meter delta loop.
Back on WSPR this morning with WPSR-X. Running 250 mW in to the 30 meter delta loop. I like the interface on WPSR-X. Being a JT65A/JT9 operator, WSPR-X provides a very familiar interface.
WSPR-15 has spark my interest. Anyone using WSPR-15 on 160 meters? Or are there a few daring souls out there who will give it a go in HF?
We have had a heavy (record high about 70cm) snow this morning,
but condition on 6m was very good.
I've got 104spots from 14stations in VK.
Condition lasted incredible over 5hours.
Is this propagation only TEP?
I can't see the Es layer over Australian continent.
Heard VK1KF at 2146 UTC (02/09/2014)... Amazing! Don't hear many VK's at
this location! Pretty good mileage for 5 watts!
Will be visiting my daughter in Townsville, Queensland in June - looking
forward to the trip!
In the last days I was dropping my power from 200 mW (QRO) to 100 mW to 50 mW to 10 mW and to 1 mW. And my score km/Watt was continuously rising. When I wanted to shut down the station (my Ultimate3) from Hans Summers another OM said: "Why don't you turn down the power even lower?" I answered: "I could not code it in my report. The bottom line is 0 dB."
What the hack: I switched with my the step attenuator another 3 dBm and had now 26 dBm that's 0.5 mW.
It took a while, but then I got a report and it was over 912.000 km per Watt.
Not bad for a starter ;-)
Since the beginning of the winter I'm mostly focused on 160m. With the arrival of my TS590 I wanted to verify its ability on MF instead of my Drake.
That first night of this winter was a success with 47 rx dx spots for 5 unique NA calls:

Success was shared with 11 others EU stations: G3XKR, DL-SWL, DL4YHF, PI4THT, F4DTL, PA3ABK/2, PE1RKT, F4HBT, F4DZQ, G3XBM, EI0CF.
Thanks to all, 73
In CQ Magazine current issue, you can find an article I wrote about my WSPR DDS beacon.
It uses cheap parts (MSP430, AD9850 DDS, optional LCD) and does not require GPS with good accuracy "out of the box".
All materials, schematic and source code (GPL license) are provided freely.
This is the beacon I currently use on 80m.

I t took me a while to get the Ultimate 3 from Hans Summer going. It was of course my fault, for I didn't RTFM.
And I played around with a variable resistor and destroyed settings which Hans had already done. And it was an important setting the wave form coming from the DDS. But with my new scope it was easy to restore this setting and the TRX began to work. But there was another hurdle: It is so tiny and there are a lot of cables coming out of the rig.
Running new WSPR project based on STM32 Discovery board.
Initially it was an attempt to use this nice board and it's integrated ADC as fully self contained DDC-like SDR receiver of 60 khz WWVB signal using new phase modulation mode.
After successful completion it was a question of time how to convert it into standalone WSPR (and QRSS) beacon.

I had several decodes in the early hours today from N1NAZ. This was the best SNR:

I was using a 40m delta loop at about 10m high for the main horizontal(ish) section.
The goal of my 160m season is already reached. After the latest night, my 160m Challenge of reception include 29 unique callsigns of North American stations. I finished the previous season with a count of 27. So I hope now to "blow up" this score because the period is not over.
I have a great pleasure to publish this list with the power to show the qrp spirit of all the station i heard.
up to january 28- 2014- NA listing - Call (pwr): VA3MW(1w), W1FVB(0.5w), WB5WPA(5w), VE3SWS(5w), K4RCG(5w), K9PAW(1w), K9YWO(1w), KE7A(5w), KU4XR(5w), W8AC(5w), K5DNL(5w), W3PM(5w), N2NOM(5w), N0NCO(5w), W1CK(1w), N1NCO(5w), VA3XH(5w), VA3SK(2w), KC2STA(5w), WD4ELG(5w), W3TMB(5w), KA1SX(5w), W9HAK(5w), K3PGP(1w), W3ZUP(10w), N9XG(2w), W5CGC(10w), KD2MX(5w), N1NAZ(?).
Many thanks to all, 73 -Patrick
I am running tests between two antennas in the garden Friday morning on 10m (28.1246MHz), between 10:00 UTC and 12:00 UTC. Would appreciate some spots out there if anyone is game. Assuming 10m is workable that is.
My first VK spot using a 1metre dia magloop made from junkbox bits (heavy copper wire, no tubes) at no cost at all!

OMG, amazing what a bit of 'wet string' and 100mW can do:

Many thanks to VK2WD for the report - still can't believe it!
Since September 2013 start date of my new season on 160m WSPR I was happy to know that Leigh (VK2KRR) came back to the 160m. I was a little impatient to spot again Leigh . The last time was on 25/04/2012 .....
Well last night, as we say in French "J'ai remis le couvert" (I've done it again) :
2014-01-21 19:24 VK2KRR 1.838101 -25 0 20 QF34mr JN07th F59706 16864 306
It's really fun because we are really few(5 stations I think) in Europe to have yet decoded his signal.
I am grateful to Leigh for its regular presence as well Derek (VK6DZ) (not yet in my log).
See you again Leigh,..
