OK Laurence,

Well, on the EU TA path it looks quite good, Jay is getting good results at that time. There was some snow here, about 5 cm, which melts now. So its all wet and thus the losses a bit higher, maybe 1 dB max.

About MF. I'm getting first impressions what is possible on 630m in distances > 5000 km. It looks not easy at all to make that distance above a land path. E.g. UA0SNV got me in QRSS-10 on LF but MF looks to be much harder. OK my LF signal is stronger than my MF signal though, anyway the difference is higher.
Would you think there may be a chance to see traces in QRSS-10 or DFCW-15 on 630m in AK?

73, Stefan

 Beacon away Stefan -:-)  Im looking at HF conditions over the Pole,  QRSS snapper at  http://kl7uk.com/Alaska.html  and I can normally very roughly scale these for LF/MF - ie "when its not good on any HF band to Eu its likely that MF or LF will be worse syndrome" - this only holds for here....
 
At the moment Im seeing only weak signals with some spreading at 10MHz with that lovelyfast doppler sound which again isnt a good sign - and thats with a K=1 at mid lat.
 
I didnt see any Aurora last night as I was fixing up my 8 inch Meade telescope but had difficulty in looking at anything as the water vapor from my eye condensed and froze onto the viewfinder. Takes me back a few years when we were still using Sextants for Polar travel -  
 
The nice thing is the gear is not all moved into the office and I can sit in comfort and not freezing my Annulus off.

Hi Laurence,

I wish you good luck. The best chance may be to appear at DF6NM's µHz spectrogram. I don't expect you to see you in my 22 mhz spectrogram so i will have an eye on Markus' results and will be on air for myselfe this night again, BACON to the west, in DFCW-90 on 136.172 kHz, as usual ;-) Or do you want me to watch out for you as well?

73, Stefan/DK7FC

WE2XPQ will be conducting a continuous carrier test overnight on 137.7800 kHz from around 0100Z till around 1600Z Tonight (thats in a few hours time).
 
Conditions over the Polar regions are getting better but less than fair at the moment but worth investigating. A no show is still a result :-)
 
Transmitter will be the GPS/10MHz disciplined HP3336B via 4046 squarer and 4426 driver to the Decca 5501 Amp at around 600W into a Fir tree 140m loop - ERP is likely to be less than 0.5W in the main lobe 040/220deg T
 
The loop will be modified this coming week if the weather breaks but its been blowing 40Kts gust and -25C so still nippy on the face and fingers to do long term outside work. We are also in a "Red Flag" warning area so have to be careful with sparks and flames..
