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

High QRN in North America seems to be impacting just about everyone in some way; Geomagnetic conditions were headed in the right direction but storm levels returned during the evening; A few trans-Atlantic and trans-Pacific openings observed but band continues to be poor for long haul paths; THE ONLY THING TO MATTER FROM ALL OF THIS IS THAT THE FCC ISSUED THE R & O FOR 137 kHz and 472 kHz TODAY!

– Posted in: 630 Meter Daily Reports, 630 Meters

So, the important stuff first:  here is a link to the FCC R&O for 472 and 137 kHz…. IT LOOKS LIKE ITS GOING TO HAPPEN!

The details for March 30, 2016 can be viewed here.

Big storms continue in the Midwest, South and Gulf coast regions of the US overnight and a few storms created noise in Northern California this morning.  The band sounded like the typical mid-Summer roar here in Texas and while S/N number suggest that JT9 QSO’s might have been possible, I’m not sure the exercise would have been worthwhile or fun.  In Queensland, VK4YB reported that the eye of the cyclone  moved over his QTH during the afternoon and the path to North America was open a bit.  Domestic openings seemed to be much improved over what many indicated from the previous session.

Geomagnetic conditions were unsettled for much of the day and there were some hopes of recovery but storm levels returned in the late evening.  The Bz has been variable as the roller coaster ride continues but is currently pointing to the North.  Solar wind velocities are currently averaging 625 km/s, in the high category and DST values continue to suggest disturbed band conditions, particularly after the evening Kp spike.

 

 

 

There were a couple of trans-Atlantic  openings for WD2XSH/17 which was an improvement over the previous session.  Report details can be viewed here.

Al, K2BLA / WI2XBV, reported that his QRN was worse this morning than last night, which was also bad, with S-meter readings up to 20 dB over S9.  He was able to report a better night of statistics receiving reports from 22 unique stations including WH2XCR and he provided reports for seven WSPR stations.

Paul, N1BUG / WI2XTC, reported constant, moderate QRN through the session.  He decoded ten WSPR stations but no trans-Atlantic or transcontinental stations.

Ken, K5DNL / WG2XXM, reported that he decoded five WSPR stations in high QRN and was decoded by 56 unique stations including eleven Canadian stations.

Doug, K4LY / WH2XZO, reported, “Similar noisy conditions with high latitude attenuation last three nights.  My 10 unique decoded and 30 who decoded XZO are typical for the period. More thunderstorms next 36 hours.”

Rick, W7RNB / WI2XJQ, reported that the band was slightly improved at his station in Seattle.  He provided reports for nine WSPR stations and was reported by 24 unique stations.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, reported a tough night for listening near Pittsburgh.  He indicated no reports for WH2XCR and -23 dB S/N for the best report of WH2XGP who had been at single digit S/N levels just a few days ago.  Mike provided these additional statistics:

Roger, VK4YB, reported that after the eye of the cyclone arrived at his QTH, “…The wind stopped and it was brighter. Not a breath of wind. Not a leaf moved. It was eerie. Then the rain and wind started again.”  He reports that his antennas are find and he provided reports for WH2XGP, WH2XCR, and WH2XXP.  He appears to have been “receive-only” through the session.

John, VK2XGJ, reported surprise at seeing decodes for WH2XCR, WH2XXP and WH2XGP.  John’s noise has been high from the storms to his North as well so the appearance of received stations is a welcome sight.

Ward, K7PO / WH2XXP, received reports from 56 unique stations including VK4YB, VK2XGJ and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations and was decoded by forty unique stations including VK4YB, VK2XGJ, and ZL2AFP.  As W7IUV, Larry provided reports for nine WSPR stations.

It was good to be back on the air after a few harrowing weather days.  There is more to come this weekend unless the forecast changes.   It was noisy during the evening and overnight but domestic openings were relatively  good.  Both WSPR transmit and receive numbers were down but not unexpected given the current geomagnetic and terrestrial weather conditions.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

Eden, ZF1EJ, provided reports for seven WSPR stations and was decoded by eleven WSPR stations.  He shared two-way reports with WH2XCR.

Laurence, KL7L / WE2XPQ, reported heavy snow in Alaska and was only receiving during this session.  Given the poor conditions, its nice to see some signals making it that far North.

Merv, K9FD/KH6 / WH2XCR, shared two-way reports with ZF1EJ and received reports from WE2XPQ, VK4YB, VK2XGJ, and ZL2AFP.  New England remains elusive to Merv as the geomagnetic conditions and high QRN continue but a few decodes from VE4 and VE6 were completed.  Merv’s DX report details can be viewed here.

Jim, W5EST, presents, “SKY WAVE AND GROUND WAVE DIFFER IN MICROFREQUENCY: NIGHT TWO”:

“Today’s three illustrations successively show 600 KHz BCB carrier at sundown and evening, then night, and finally late night and sunrise March 28.  Storms cleared and results paralleled the previous night.  In particular, the third illustration shows another instance of a sunrise enhancement claw or spur out 100 milliHertz in frequency departure from the main carrier line.

Discussion parallels an earlier detailed blog about this experiment. http://njdtechnologies.net/032817/   In another blog post, let’s talk about the sunrise 3D propagation geometry that I think is probably responsible for MF sunrise enhancements. TU and GL!”
