High latitude transcontinental path much improved, VK3ELV <--> WH2XCR –> JH3XCU/1 returns, very quiet conditions and very strong signals

– Posted in: 630 Meter Daily Reports, 630 Meters

This session is characterized with significant improvements in the higher latitude transcontinental path.  John, WA3ETD / WG2XKA, indicates that the stations in the Pacific Northwest were heard at his station in Vermont but the path was not reciprocal.  Doug, K4LY / WH2XZO, reports that the spot ratio for WH2XGP and WH2XXP increased from 1:50 two nights ago to 19:92.  It seems the quieter geomagnetic conditions are helping paths that are closer to the auroral zone.

The Kyoto DST continues to trend upward.  These improvements may have injected enough turbulence into the ionosphere to restore the path to JH3XCU/1 from WH2XCR.  It seems stability is not necessarily the only answer to that path.

WSPR dominated the session, with 72 MF WSPR stations observed on the WSPRnet activity page during the North American evening. Two new stations were observed: VE6JR and WM4P.

The noise floor was extremely low through the session.  Even WSPR signals on compromised or still-recovering paths were audible in many cases.  Here is a screen capture from this morning showing the waterfall and all of the stations that were observed during the previous hour:

In the Caribbean, Eden, ZF1EJ, is joined once again by Roger, ZF1RC.  Both stations were hearing very well, including Eden’s reports of WH2XCR.

Laurence, KL7L / WE2XPQ, had a better session, being heard along the west coast of North America and in Hawaii.  Laurence reports visual aurora through the session.

Propagation in the Pacific was huge, where Merv, K9FD/KH6 / WH2XCR, was reported again in Japan and all along with east coast of the US.  Merv also had a reciprocal path to VK3ELV, a path that has been single-direction for some time.

Other anecdotes, statistics and comments from the session follow:

Larry, W7IUV / WH2XGP, reports that he was decoded by 38 unique stations while hearing ten from Washington state.

Neil, W0YSE/7 / WG2XSV, indicates decodes from 18 unique reporting stations.

Ken, K5DNL / WG2XXM, reports decoding 10 unique stations.

Doug, K4LY / WH2XZO, indicates that he was decoded by 38 unique stations including VE7BDQ, which was only the 2nd time to ever occur.  Doug decoded eight stations through the session.  Doug QRTed prior to sunrise due to heavy rain in his area.

Andy, KU4XR, reported the following on the 600-meter research group email reflector:

There was no CQ session this morning on 474.5 kHz CW and I suspect there will not be one tomorrow morning either.  I hope to operate CW during the evening on Friday if the schedule works out.
