G4SWX copied the Canadian group VC1T for 4 hours, but was unable to complete a 2-way QSO. The Canadian's ERP was around 150kW from a beam 100 foot long. The mode was FSK441 and this was on July 6th 2014. A 2m 2-way terrestrial QSO will happen across the Atlantic sometime, maybe this summer?
My thanks again to Steve G1KQH for this news.

Ultimate 3 kit build
I thought my hands and eyes were good enough to make a start on this kit, which I have only just unpacked, having had it for months. I was waiting until I was less clumsy. When built, this will make a really useful WSPR beacon.
The packing is wrong as I had asked for a GPS module, which is missing, but there is a surplus relay board in the box. I was very careful unpacking the kit. and have left in packets those parts not yet needed. Some are anti-static.
Sadly, my eyes and hands are not really good enough: I started on the 10m LPF PCB and, frankly, this was a real struggle both for my eyes and hands. Tomorrow I shall test this with my generator and 50 ohm load.
Two people have very kindly offered their help building the kit. I fear I shall have to admit defeat and ask them to help me. This is a great pity as I was so hoping I'd be fit enough to build this. Sadly, this seems unlikely any time soon. My stroke is taking its toll on my abilities. WSPR is OK, but I am struggling with building still. Talking in tonight's contest will be hard.

6m WSPR and 70cm UKAC
So far today, 6m WSPR is running to form: most spots are from local and semi-locals, a smattering of Es (but nothing like the Es on 10m) and no "super-DX" to be seen here. If I QSY back down to 10m I am almost guaranteed S.American F2 propagation, but "sod's law" says I'll miss a stronking great big opening to the Caribbean on 6m. I am bound to do the wrong thing! For now , I plan to stay on 6m. We'll see.
This evening is the 70cm UK activity contest. I plan to operate for the first hour or so, as long as my voice holds - I am not good at SSB contests because of my stroke damaged voice - it is really hard work. About 10 QSOs is my very limit. At least I can WSPR on 6m at the same time as I use different rigs and antennas (both FT817s). WSPR saves my voice.

Another Pixie
Yet another variation on the Pixie arrived by email today from Sverre Holm in Norway who has LM386 mods to reduce BCI, provide mute and add sidetone.
See http://la3za.blogspot.no/2003/04/using-pin-7-of-lm386-to-reduce-bci-and.html .
This looks a very useful mod to this simplest of circuits. Sverre also added a much wider tuning range that helps to get contacts. Low power does not seem to be the main handicap.

6m WSPR
After a very brief spell on 10m WSPR before 0808z, I QSYed back to 6m WSPR very early today. 10m was very busy with Es coming through from right across Europe.
On 6m, in the early morning, a couple of Germans were spotting my 1W ERP WSPR signal, but since then just locals and semi-locals.

10m tomorrow?
Tomorrow morning, I think I am going to take a look on 10m WSPR rather than 6m. I may go on to 6m lunchtime onwards. 6m (apart from some Es, GDX and locals) seems pretty quiet. Later in the day there is still a chance of some super-DX across the Atlantic, but I'm not holding my breath!
Polyakov Pixie
Peter DL3PB has sent details of his version of the Pixie transceiver. He claims no broadcast breakthrough by using this configuration and lots of QSOs.

6m - past the best?
I am beginning to think that 6m is now past its best both for Es opportunities and, of course, for F2 propagation. Almost zero Es on 6m in the last few days, mainly locals and a little GDX. I may give it a few more days before QSYing back down to 10m where both Es and F2 DX are more plentiful.
10m conditions should be good for N-S F2. Sunspot count is 256 (high) and 20-30MHz propagation is forecast to be "normal".
If anything, solar activity has staged a bit of a comeback lately, but this may be just a blip.
UPDATE 1545z: As if to persuade me to stay on 6m, CN8LI (2113km) was spotted at 1450z.
UPDATE 1810z: No more Es here since CN8LI at 1450z. One blog reader tells me that I should try JT65 as there is more activity. JT9-1 worked well for me on MF with international 2-way QSOs with very low mW ERP. I think JT65 is more commonly used on 6m?

6m - quiet overnight, now some GDX
6m remained quiet here overnight with just local reports but at 0728z I was spotted by G8JNJ/A (184km) weakly. This is the first GDX spot of the day. Later, at 0834z, M0EMM (192km) was decoding me at -20dB with what seems to be aircraft Doppler (-3Hz)
No WSPR spots of others yet but reasonable signals about 1 minute long seen (MS or aircraft?). Maybe JT65 would be better with a 1 minute decode period? Some of these shorter bursts are actually at strengths JT65 would have no trouble with. JT65 is usually a few dB worse than WSPR but is a proper 2-way comms mode, whereas WSPR is really a beacon mode.
Yesterday my WSPR software crashed so I reset the clock and restarted the software this morning to be sure all was OK.
My TX periodicity is now much lower (around 10% TX) so I am listening far more than transmitting. No stations copied though for very many hours!
UPDATE 1051z: M0EMM (192km) copied at -27dB S/N at 0940z. This is my first WSPR spot since yesterday. No Es here (yet) today. M0EMM is the station I have been seeing for hours (judging be frequency) but with TX periods less than 2 mins (MS pings?).
UPDATE 1235z: M0EMM spotted again here at 1224z. Still no 6m Es here today.
