Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

Many reporting pockets of noise but band continues to be serviceable on a number of modes; Beginning to see a few stations from VK not seen in months on KH6 path

– Posted in: 630 Meter Daily Reports, 630 Meters

This session was similar to the previous.  The band will support communications to a number of destinations and stations located further away from storm systems will find the most success.  This session yielded three relatively large M-class flares yesterday in North America.  Whether the accompanying absorption that the increased X-ray flux brought had any impact later in the session is up for debate (D-layer would be diminishing but E-layer would continue to be in play) but I do note another later start to reports from my stations although it it conceivable that storm noise at receiving stations in the East was the primary culprit.  I do want to report very late, post-sunrise reports of my signal  by NO1D in Arizona.  These reports have been on going for a few days.

Geomagnetic conditions were stable and quiet.  The Bz was at or near unity, averaging neither North or South over the entire session and solar wind velocities are at low levels, below 400 km/s:

Ken, K5DNL / WG2XXM, reports that he decoded three WSPR stations and was decoded by eighteen unique stations including 31 reports from WH2XCR, best at -9 dB S/N.

Phil, VE3CIQ, reports that he decoded VE3EFF, WG2XIQ, WG2XXM, and WH2XNG using WSPR and was decoded by VE2PEP, W8RUT/E and WI2XFI. Phil noted a steady static level at +10 dB in the evening.

Neil, W0YSE/7 / WG2XSV, had a better night with more spotters and a good path to KH6:

WG2XSV 072416

There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths.  UA0SNV was present but no reports have been filed for Vasily’s station at this time.

Merv, K9FD/KH6 / WH2XCR, experienced the normal compliment of VK stations and added VK5ABN who has not been observed since last Winter in KH6.   Yesterday VK3HP was reporting so it seems that we are beginning to see activity from a few more stations in Australia.  Merv reported that his hurricane warning was down graded to a tropical storm but conditions are very fluid and could easily change again.  How this activity impacts his propagation continues to be a mystery but observations over the years suggest that terrestrial weather may figure into propagation in KH6.  More data is needed.
