The sun is slowly retreating Southwards but we are still in Nautical twiglight at best here in Alaska. Nil returns from 137KHz except JA @ around 5000Kms on QRSS which we havent lost thru the summer

On 600m  DX still coming thru with WSPR2 rx from stations from 1W ERPish Lower 48 states at over  land path >4000Kms but getting a diode affect with XPQ only getting out to around 2700Kms even with my larger ERP  _

 I guess if you plot the sun/iono/shadowing and my launch angle on the tx side compared with incoming signals it kind of makes sense as not being reciprocal, perhaps... - I got very used to this in the High Arctic on some Polar expeditions, sort of wants me to pull down this tx loop, but with about -11dBish "gain" I cant expect the world but Im going to resist the temptation

The sun is at best only a couple of hundred miles to my South, so some interesting geometry. 

I saw over 20 active 600m rx/tx stations last night on WSPR2 between both large ponds

Have a nice day
