Ron WH2XND (NI7J) Phoenix Az has been running tests down on high 60's and mid 70kHzs' and last night reverted back to WSPR2 (!) on 75.550kHz (carrier) - or 74kHz WSPR USB dial if you like, and made the trip tp W7IUV, K7PO, VE7BDQ  and this station (4059Kms) on the Pacific side, and is presently reaching SWL/K9 in EN61 @ 2350Kms during daytime. 

Hes on +24hr for the moment and I have no doubt he will make the trip over waters as we get into the Autumn. Its still light outside here at night so delighted to receive him in Alaska.  I think hes using a reasonable Marconi and a few hundred.

well done Ron -
