Not a short distance but almost completely over sea water and the common dark times are higher than for me.

 Im hoping this will be good enough for a long term overnight "go" when I finish the loop antennae, though this wont happen now till the first week in Oct. There is no path to Europe as such at the moment - well its really dodgy but the path to VK and ZL would be pretty good at the moment given past signal receptions from ZL6QH et al.
 
Given past openings to Europe during the deepest part of Winter (Dec and Jan) Pre dawn Eu say 0400Z was the best with Peter LDO/DF6NM/G3AQC/DK7FC but Stefan managed to get to Alaska at around 1600Z too. I cant recall receiving any ham signals on 137/500 before December - but SM6BHZ may have made it over the pole earlier on 500 on WSPR in Nov. Im getting built around so the s/n is getting marginally worse - but thankfully to the North is just a lake.

Laurence,
 
I'd be interested to see whether XPQ could be detected in a microHz spectrogram here, either on Chris' grabber in Bucharest
or mine in Nuernberg. Can you give your exact frequency, and could you transmit a stable uninterrupted carrier for a couple of hours? We've been seeing narrow traces from US East coast stations before, but I wonder how much effect transpolar Doppler could have.
 
Is DCF-39 really as strong as 25 dB in 100 Hz, ie. 45 dB/Hz, or would that be in 0.1 Hz? What are the best hours?
 
Best 73,
Markus (DF6NM)

Nice to see DCF39 appearing on QRSS this evening over the Pole. Ive not seen it since Spring here in Alaska. About 25dB noise in 100Hz (ish units). Not dark yet either,

Further testing on 137.7752 ish carrier only ongoing - still in shakedown mode but sweeps of individual 400w Modules show the same resonance and output parameters from 2005 :-)

A little bit of Nostalgia - WE2XPQ Wasilla Alaska is very intermittently testing on 137.7752 DFCW various speeds and the odd bit of QRSS - Power will be up to 2W ERP but is to be confirmed.
 
Periods of operations, modes and powers will vary as Im trying to remember all the ins and outs of why I installed 'X" relay to do a "Y" function as its been 7 years or so.
 
Transmitter for the moment is the Decca 5501, drivers are FT817 h/b transverter, Loop with around 100m circumference at 50ft or so and phase meter. The Birch trees bend a lot more than the OKie Cottonwoods so not sure how much detuning will happen as thing become more slack or as the trees become snow laden -
