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

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Slight improvement for trans-Atlantic openings as noisy storm system moves into the southeastern US; Domestic openings reasonably good; Trans-Pacific openings to North America at least as good as the previous session; Geomagnetic conditions improve through the session

While storms persist in the South and East, lightning QRN appears to have been less of a player than the previous session for many stations.  That doesn’t mean it was quiet for everyone but as far as lightning strikes are concerned, there were fewer during this session than the previous and several stations that had been QRT in the previous session returned to air.  Driving rains were reported in New England so precipitation static may have been a player there.

12-hour North American lightning summary


Propagation was pretty good, particularly on domestic paths.  Long haul openings on both coasts were better or at least as good as the previous session on first glance.

Geomagnetic conditions improved through much of the session, decreasing from elevated-quiet to quiet by morning in North America and reaching the lowest levels in several days.  The Bz is currently pointing to the North and while solar wind velocities decreased below 500 km/s for a portion of the session, velocities have recently increased above 500 km/s again.  DST values have been variable although the trend seems to be toward positive levels.




Trans-Atlantic openings returned during this session, including European signals reaching North America, which has been absent for several days.  Report details can be viewed here.


WG2XJP -> F1AFJ, F59706, G3XKR, PA0RDT

Paul, N1BUG, indicated low QRN at his station in Maine.  He decoded twelve WSPR stations including EA5DOM.

Doug, K4LY / WH2XZO, experienced a rainy night but managed to stay on the air without antenna adjustments:

“The 13 decoded and 37 who decoded XZO last night, though mediocre, followed the worst conditions since summer the night before.  Last night’s rain didn’t change the SWR a whole lot.  Earlier last fall I used a 1/4′ coil made of flexible copper pipe for base inductance which was probably very efficient (high Q).  I used a second small tapped Bud coil to tweak the SWR which seemed to change every time there was a breeze or spit of rain.

In late fall, I replaced the copper tube coil with a Bud coil and have now gone several months since buying the Monitor Sensors 630M transverter, which has SWR protective circuiitry, without having to make any change to the loading coils.  The two old Bud coils, no variometer, just sit there near ground level, and I haven’t had to tweak the setting even in rain, wind, and snow.  It stays below 1.5: 1 and is  1.1: 1 when dry.”


Al, K2BLA / WI2XBV, reported high QRN from lightning this morning resulting in less than an hour of operating time at his station in Florida.  He received 88 decodes from 33 unique stations, and decoded nine WSPR stations including stations in British Columbia, Alberta, and Hawaii.

Ken, K5DNL / WG2XXM, reported that he provided reports for thirteen WSPR stations and was reported by 56 unique stations including two-way reports with WH2XCR.

John, VE3EAR, reported good results as he decoded ZF1EJ for a second consecutive night:

“Two nights in a row I’ve decoded ZF1EJ on WSPR-2 mode, so it wasn’t just a fluke yesterday! This is a small snip from my log, there were actually multiple decodes throughout the night:

0336  -27  -0.9    0.475664    0   WH2XXP       DM33    47
0336  -31  -0.9    0.475705    0   ZF1EJ            EK99     33
0336  -18  -1.1    0.475795    0   WG2XIQ        EM12     37″

Rick, W7RNB / WI2XJQ, reported a strange session with reports only as far East as K8PZ but he did make it to ZF1EJ to the Southeast, a path that intersected a noisy storm system.  Rick provided reports for six WSPR stations and was decoded by 26 unique stations.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, provided a few transcontinental reports.  He provided the following statistics:

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

Roger, VK4YB, reported, “Static increased throughout the session. Seemingly good traces from WG2XXM failed, annoyingly, to decode, when I was expecting a S/N of -28 or thereabouts.  Propagation to the North East was good and outgoing spots were plentiful. Until now the JA path has not opened.  630m/160m comparisons with VE6XH continue. 160m 4 spots, best -16, 630m 3 spots, best -26.”  Roger received reports from CF7MM, VE6XH, VE7BDQ, and W7IUV.  He provided reports for WH2XXP and WH2XGP.

Phil, VE3ELV, received reports from JH3XCU.

Larry, W7IUV / WH2XGP, provided reports for thirteen WSPR stations  and received reports from 46 unique stations including VK4YB.  As W7IUV, Larry provided reports for eight WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from sixty unique stations including VK4YB and JA1NQI.

I thought this was a fine session.  QRN was not very bad here in spite of gulf storms and signals were strong.  The lengthening days complicated early evening reports as Spring propagation patterns seem to be taking hold.  Daylight savings time begins this weekend so it will begin getting dark even later.  I’m already ready for Fall and Winter again.  I only operated WSPR during this session as I was spending some time listening on 160m during the evening and briefly this morning.  W1AW was quite loud during the evening and a few JA’s were detected this morning.  The only relevant QSO was with HR5/F2JD who was strong but heavily impaired by QSB.  My 630-meter WSPR transmission report details can be viewed here and my reception report details can be viewed here.

Laurence, KL7L / WE2XPQ, reported that he was QRT overnight due to a wind storm but he did manage a bit of pre-dawn activity, allowing reception reports for VK4YB and two-way reports with WH2XCR.  Report details for these stations can be viewed here.

Merv, K9FD/KH6 / WH2XCR, experienced another typical, successful session with reports from 7L1RLL4, JA1NQI, JE1JDL, JH3XCU,  and two-way reports with VK4YB, WE2XPQ, and ZF1EJ.  Merv also provided reports for VK3ELV.  Coverage in the East resulted in reports from WA3TTS, WH2XZO, and WG2XJM.   Additionally, WI2XBV in Florida was reported by Merv.  Coverage in the central and western portions of North America was typical.  DX report details can be viewed here.
