Thanks Stefan - yep it was worth the effort and I think im going to, for a giggle, use the two dipole legs and connect up as a ground isolated, current choked counterpoise just to see the net effects, compared with the ground mat/radial system or perhaps a combination of both. The aerials are nested in the forest so we have a lot on unwanted coupling to the flora - things will improve on leaf drop and colder temps

Looking forward to seeing you or perhaps seeing me over the pole later in the season. Loads of solar type attenuation up here at the moment and the path is still far too "lit"

Cheers

Hi Laurence,

Nice experiment. A few OMs tried a full size dipole for MF now, me too. TX wise it is not as bad as expected by some theoretical focused OMs, despite the little height above ground. For /p, it is a real alternative, better than a 10m vertical i think. But there are better systems, as you say.
Good luck in KH6. This may be interesting for the VK / ZL OMs!!

73, Stefan

WE2XPQ Palmer Alaska is on CW info  loop 475kHz thru today for continued ground wave profiling - will be on WSPR2 tonight. 200W TPO - and a few Watts ERP.  Mix Pol.
 
We tested a full size squashed (over 5 acres) resonant dipole at 30ft for 475kHz (some 500ft each leg)  last night but it didnt manage to get a signal out of State - Z was 100ohms given its 'folded state' but was matched at feedpoint ok - I dont intend to keep this up as its Dx performance on rx was "ok" but typically (but not all the times) worse than the K9AY and L400bs. It took me nearly 4 days total time to errect as I was interested to at least try it out against the calcs and books -  Ill probably use of the the legs and readjest heights into some form of long wire/beverage.
 
Conditions are still pretty dire with no station >3000Kms decoded last night. Hope the Coronal holes, CME, elevated College K, Protons all go on holiday soon. Nothing coming over the North or South poles at the moment.
 
Talking of holidays -
 
Early heads up I hope to be QRV some nighttimes on  MF rx from KH6 20th Sept for about ten days - unsure if it will come together but liable to be a mobile set up on the wrong side of the islands for USA - unlikely real time uploads this time around. Asus Netbook/SDRIQ/L400 variant
