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

Trans-Atlantic paths completely cut off but trans-Pacific openings to Oceania rebound; KL7L/XE listening from the beach; Only one long haul JA report observed during the session

The details from April 1, 2016 can be viewed here.

It was much quieter during this session in Texas while points East indicated that noise levels remained high as storms continued off the coast of the mid-Atlantic region.  KC4SIT reported that his noise in North Carolina was S7-9 and stations in the Northeast indicated that evening noise was moderate.  A new system is approaching for the weekend and noise is sure to return:

Geomagnetic conditions were at unsettled to elevated-quiet levels for much of the session as the streak of days at storm levels is finally broken.  The Bz is pointing to the South and solar wind velocities are beginning to decrease but continue to average near 580 km/s.  DST values are improved but continue  at negative levels.




There were no trans-Atlantic reports for this session.

Paul, N1BUG / WI2XTC, reported moderate QRN that decreased to low levels by morning.  He decoded seven WSPR stations but indicates no transcontinental openings were observed.

Al, K2BLA / WI2XBV, reported “tolerable QRN” this morning, hearing nine WSPR stations and receiving reports from 34 unique stations.  He shared two-way reports with WH2XCR.

Rick, W7RNB / WI2XJQ, surmised that noise must have been high back East but notes that activity seemed to be pretty good.  He provided reports for fourteen WSPR stations and was decoded by 39 unique stations.  Rick’s unique report details can be viewed here.

Ron, NI7J / WH2XND, reported that he “…spotted 12, Larry spotted 14; I’m surprised of being able to spot these stations with mod K9AY with 137 transmitting 75 feet from K9AY!  The Kiwa 500 KHz Low Pass filter seems to be working.”

Ernie, KC4SIT / WI2XQU, reports, “Clear, cool sky. Noise a steady S-7. I spotted 11 unique stations.”

Neil, W0YSE/7 / WG2XSV, reminds us of the value of JT9 as a QSO mode on 630-meters and his receiver that is running daily to allow stations to check their signal at his Vancouver, WA QTH.  Neil explains and files his overnight WSPR report:

“Please let the 630m ops knnow that I always have WSJT-X working for JT9 on 630m at the same time I am doing WSPR. So anyone who wants to get a report on their JT9 signals can give out a burst of JT9 RF and I will send them a report the next day if I receive their signal. JT9 will probably be one of the main modes of quick QSOs when we get the band.

Here are the wspr results for last night at WG2XSV (running 2w EIRP):

Heard these 10 stations: VA7JX, VE7CA, VE7SL, WG2XIQ, WG2XXM, WH2XCR, WH2XGP, WH2XXP, WI2XBQ, WI2XJQ

Heard by these 27 with WI2XSV south of Chicago being my eastern DX this session:



Trans-Pacific openings were the big story for this session.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, submitted these statistics for JA DX reports from February 18, 2017 to March 31, 2017.  The peaks are interesting.  These statistics are also posted on the 472 kHz Japanese language site which can be found here.  He also submitted these daily statistics showing NA/VK -> total JA DX  and NA -> JA peak S/N for the session.

Roger, VK4YB, reported that, “QRN was low for most of the session. There was a very good TP opening from 11:00 to 11:20z. After that it tailed away rapidly. I spent 1 hour on the JA beam to no effect.  VE6XH stats: 160m 3 spots, best -21, 630m 4 spots, best -25.”  Roger received reports from VE6XH, VE7SL, W7IUV, and WH2XGP.  He provided reports for VE7CA, WG2XXM, WH2XGP, and WH2XXP.

Steve, VE7SL, reported a great night running just 20-watts TPO.  He received reports from thirty unique stations and provided reports for seventeen WSPR stations, including VK4YB.

Mark, VE7CA, provided reports for thirteen WSPR stations and was reported by 33 unique stations including VK4YB.

Ken, K5DNL / WG2XXM, reported that he decoded nine WSPR stations and was decoded by 73 unique stations including VK4YB and ZL2AFP.  Ken added that he also decoded VE7SL’s 100 mW ERP signal.

Ward, K7PO / WH2XXP, received reports from 73 unique stations including VK4YB, VK2XGJ, ZL2AFP, and TNUKJPM.

Larry, W7IUV / WH2XGP, provided reports for fourteen WSPR stations and was decoded by 58 unique stations including VK4YB and ZL2AFP.  As W7IUV, Larry provided reports for twelve WSPR stations, including VK4YB.

It was great to see lower noise levels during the evening in fact they were low enough that I felt comfortable airing out a bit of CW around 0200z.  Openings seemed to be very good, particularly domestic paths in spite of elevated noise levels in the East.  WSPR reports were quite good and Ernie, KC4SIT / WI2XQU, submitted this screen capture of my signal just prior to starting my CW activity:

My WSPR transmission reports were very good with a number of CW-level reports by morning and JT9-levels through the night and those report details can be viewed here.  My WSPR receive numbers were also improved after a number of high QRN days and those report details can be viewed here.  I had intended to operate CW again before sunrise this morning but overslept after a late night of writing.

Eden, ZF1EJ, provided reports for five WSPR stations and was decoded by 25 unique stations.

Laurence, KL7L / WE2XPQ, is listening from the Yucatan at the moment and experienced pretty good results.  He indicates that he is using a probe about three meters from an adobe wall on the wrong side of a three-story hotel.  He did pretty well all things considered:

Back in Alaska, WE2XPQ is back on autopilot which saw a return of two-way reports with VK4YB.  Geomagnetic conditions must be improving.  Report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, also did not have reports from Asia during this session but the path to Oceania was quite good as he provided reports for VK3HP and VK5FQ and shared two-way reports with VK4YB.  Merv received reports from VK2XGJ and ZL2AFP, including a late, sunrise report for the latter.  Merv we hearing well providing reports for stations in the Northeast like WD2XSH/17 abd ZF1EJ in the Caribbean.  He also shared two-way reports with WI2XBV.  DX report details can be viewed here.
