Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

Weird combination of storm QRN and the return of persistent geomagnetic storm levels resulted in a slightly better session than the previous night for some; Big JA openings for WH2XXP; Trans-Pacific paths from Oceania greatly diminished; K9JWV/WI2XJG SK

The details for March 31, 2016 can be viewed here.

Lightning activity was widespread across the eastern third of the US during the evening, localizing to the Southeast and Gulf regions by morning.  The next storm system to move across the southern US was becoming organized in the four-corners area of the Southwest.  It was noisy here in Texas but not quite as bad as it had been in recent sessions.  I’m sure stations under these storms would argue that it was a raw situation, however.  Winter weather continues for some in the Northeast, likely contributing to elevated precipitation static.  In spite of all of the noise, propagation was actually pretty good, at least domestically, for stations that could fight the noise.  A few long-haul openings developed overnight but just as geomagnetic conditions begsn to show signs of improvement, the bottom fell out again.

Geomagnetic conditions ranged from unsettled to storms levels again, culminating with four consecutive periods at storm levels.  The Bz has been quite variable, currently pointing to the South.  Solar wind velocities continue at very high levels, averaging above 700 km/s for extended periods.  DST values have returned to strongly negative levels after several attempts of recovery were observed.  The band continues at strongly disturbed levels but for the moment it may be helping slightly more than hindering, at least at lower latitudes.

 

 

 

Joe, VO1NA, reported that he would be operating QRSS10 on 477.7 kHz through the evening and overnight.  Roelof, PA0RDT, reported poor propagation but he managed to see Joe’s signal:

There were a few trans-Atlantic openings overnight.  Report details can be viewed here.

EA5DOM -> N1BUG, WG2XKA

WG2XXM -> DJ0ABR, F4GFZ

Dave, N4DB, reported improved band conditions in Virginia, decoding twelve WSPR stations before disconnecting this morning as thunderstorms moved into his area.

Paul, N1BUG / WI2XTC, reported high evening QRN that decreased to moderate levels by morning.  He decoded eleven WSPR stations including EA5DOM.

Al, K2BLA / WI2XBV, reported that he had an evening “wandering noise” that was gone by morning.  Al provided reports for seven WSPR stations and was decoded by 31 unique stations but he indicates that he had no reports exceeding 4000 km.

Ron, NI7J / WH2XND, reported that he decoded nine WSPR stations while listening to the Northwest on his modified K9AY loop.

Ernie, KC4SIT / WI2XQU, provided reports for five WSPR stations before storms drove him off air.

There was a bit of JT9 activity in the Pacific Northwest and British Columbia but poor geomagnetic conditions resulted in limited results.  Brian, VA7BBG, reported that he was not hearing stations to his South as a result of the poor conditions.  Neil, W0YSE/7 / WG2XSV, received reports from Rod, VE7VV, at -25 dB S/N at 0517z.

Neil, W0YSE/7 / WG2XSV, experienced improvements and some distant static crashes that have been increasing in frequency over the past few weeks.  He provided these comments and statistics:

Mike, WA3TTS, was very close to an active, lightning-rich storm system but reports some success during the evening and overnight period:

Trans-Pacific openings exploded between Asia and North America after a few rough days.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing NA/VK -> total JA DX  and NA -> JA peak S/N for the session.

Roger, VK4YB, reported that, “TP path is barely there. One single spot from VE7BDQ. Almost no T storms in VK but some noisy ones off of Vanuatu. The big four managed to get through before they sparked up.  VE6XH stats worst so far: 160m 1 spot of -28, 630m nil.”  Roger provided reports for WH2XCR, WG2XXM, WH2XXP, and WH2XGP.

Ken, K5DNL / WG2XXM, reported that he decoded ten WSPR stations and was decoded by 63 unique stations including VK4YB, ZL2AFP, and the previously reported DJ0ABR and F4GFZ.  Ken indicated that he received reports from eight DXCC entities during the session.

Ward, K7PO / WH2XXP, received reported from 66 unique stations including VK4YB, VK2XGJ, ZL2AFP, 7L1RLL4, JA1NQI/1, JA1PKG, JA3TVF, JE1JDL, and JH3XCU.

Larry, W7IUV / WH2XGP, provided reports for nine WSPR stations and was decoded by 48 unique stations including VK4YB.  As W7IUV, Larry provided reports for seven WSPR stations.

Joe, NU6O / WI2XBQ, inquired about where experimental stations might relocate once MF and LF bands open under Part-97 rules.  Rumor has it that the ARRL’s WD2XSH operators will relocate below 472 kHz and operate from 465 kHz – 471 kHz or thereabouts.  Before anyone files a modification to their grant,  that frequency range should be verified.

It was reported in several venues last night that Jim, K9JWV / WI2XJG became a silent key.  Jim had been ill for some time but was always full of enthusiasm for radio and the low bands.

This session was much improved in spite of the elevated noise and active geomagnetic conditions.  I opted to continue running WSPR through the night in lieu of a CW session due to the noise levels.  My WSPR transmission reports returned to normal and can be viewed here although my receive numbers were down and reception report details can be viewed here.  There are terrestrial storms in the forecast and they could be big so weekend activity will be very fluid.

Eden, ZF1EJ, provided reports for nine WSPR stations and was decoded by twenty unique stations.  He shared two-way reports with WH2XCR.  Coverage along the eastern seaboard was quite good in spite of high noise levels in that region.

Laurence, KL7L / WE2XPQ, reported that his receiver was off line overnight and he will need to spend some time troubleshooting.  Weather is poor in Alaska at the moment.  He was heard by WH2XCR but that was about it.

WE2XPQ 24-hour WSPR activity

Merv, K9FD/KH6 / WH2XCR, seems largely unaffected by the current geomagnetic conditions which are often typical for stations at his latitude.  He received reports from 7L1RLL4, JA1PKG, JA3TVF, JE1JDL, VK2XGJ and ZL2AFP.  He also received reports from WE2XPQ and VK3ELV and he shared two-way reports with VK4YB and ZF1EJ.  Coverage in the eastern US was limited due to noise but other areas were relatively typical.  DX report details can be viewed here.
