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

Active solar and geomagnetic conditions during this session as storm levels finally achieved; WG2XPJ -> G8HUH; Trans-Pacific openings continue but maybe not quite as good as previous session

The details for April 19, 2016 can be viewed here.

There were a number of storm systems located in and around North America that increased QRN levels overnight but during my evening CW activity I never felt like it was a major problem, certainly not midsummer levels that we have observed recently.  Early evening propagation seemed down but some flaring occurred yesterday, increasing D-layer absorption significantly.  Longer days mean slower decreases of the D-layer in the evening.  By Summer it will be about three-hours after full darkness before the band really “gets going”, often after bedtime for many stations.

Storms were also player this morning in Oceania as VK4YB tried to determine whether this session was good enough for a CW QSO attempt with VE7SL.  Steve noted that North American storms were complicating his listening in British Columbia.

Geomagnetic conditions finally reached storms levels but I admit that I’m not sure if it was the result of the forecast geoeffective coronal hole or something else.  The Bz pushed strongly to the South during the day but has since turned around to the North.  Solar wind velocities are up but remain in the low category, averaging near 385 km/s.  DST values took a major dip along with the spike in Kp.  C-class flaring occurred during the day along with a CME that was not earth directed but D-layer absorption was significantly enhanced and magnetometer readings spiked in the afternoon.




Joe, DF2JP, indicates that he operated a bit of CW last night and was reported by DK7FC’s grabber some 250 km away.  Joe is also experimenting with RF switching arrangements for MF and LF this summer.

WG2XPJ continues to experience success on the trans-Atlantic path, although openings are very meager. Report details can be viewed here.


Al, K2BLA / WI2XBV, reported that he was QRV for only one hour this morning.  During that time frame he decoded four WSPR stations and he was decoded by 23 unique stations including WH2XCR.  Al indicates that he experienced moderate noise and notes that signals were generally down.

Phil, VE3CIQ, reported that he decoded seven WSPR stations and was decoded by twenty unique stations.  Phil adds that it is “…getting tougher to get past 1,000 kms.”

Rick, W7RNB / WI2XJQ, reported that this session was not as good as the last and he indicates that storms may have played a role in performance during this session.  Rick provided reports for nine WSPR stations and he was decoded by nineteen unique stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded thirteen WSPR stations including three stations that were in excess of 3000 km.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, reported that “QRN moderate rising through the evening and drying up the receive spots. Propagation similar to yesterday but down a little.”  He received reports from VE6XH, W7IUV, WD2XSH/20, WH2XGO, WE2XPQ, and WH2XCR.  Roger provided reports for  WH2XCR, WH2XXP and WD2XSH/20.

Ken, K5DNL / WG2XXM, reported that he decoded eight WSPR stations and he was decoded by 56 unique stations including ZL2AFP.

Rudy, N6LF / WD2XSH/20, provided reports for nine WSPR stations and he was reported by 42 unique stations including ZL2BCG.  He shared two-way reports with VK4YB.

Ward, K7PO / WH2XXP, received reports from 56 unique stations including VK4YB, VK2XGJ, ZL2BCG, and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations including VK4YB and he received reports from 37 unique stations.  Larry indicates that his SWR protection engaged overnight resulting in his system operating in a receive-only capacity for much of the overnight and morning.  As W7IUV, Larry provided reports for ten WSPR stations.  Larry indicates that he is using a different terminated loop in a different location for the Summer.  This antenna is oriented to 270 degree compared to the previous antenna which was oriented at 245 degrees.

I started the session in the late afternoon operating CW and ultimately decided to check field strength on a few more radials a few miles away.  After returning from the field strength check I intended to continue with CW through the early evening but a few chores were going to be a bit more intensive than I had expected and either getting to the radio to respond to a call or continuing to listen with the wireless headphones was going to be a challenge so I transitioned to WSPR for a bit.  The band was slow to open at quality levels but part of that was probably high noise levels from storms in the central US.  At 0200z I transitioned to CW for about 40 minutes before QRTing for the night.  I had intended on a bit of CW this morning but I did not get into the ham shack early enough.  I suspect the same operating pattern will occur tonight.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


Asiatic Russian 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for five WSPR stations and was reported by 22 unique stations.  The path to WH2XCR continues to be missing.

Laurence, KL7L / WE2XPQ, reported a Kp spike to 6 for a brief period and it seems to have resulted in an enhancement, allowing reception reports of VK4YB.  Laurence also shared two-way reports with WH2XCR.  DX report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, shared two-way reports with VK4YB and WE2XPQ and received reports from 7L1RLL4, TNUKJPM, VK2XGJ, ZL2AFP, and ZL2BCG.  Merv provided reports for WI2XBV in Florida as the eastern most station he heard.  Like other trans-Pacific paths, paths to and from KH6 seemed a bit off.  Unlike previous sessions, there were no late reports.  Merv’s DX report details can be viewed here.
