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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

A few more trans-Atlantic reports for WG2XPJ; Quiet geomagnetic conditions ahead of forecast coronal hole; Terrestrial storms in central US ‘thin the herd’; So-so trans-Pacific conditions are nothing like yesterday; WI2XUL granted to K9MRI

The details for April 17, 2016 can be viewed here.

VE7SL called my region “lightning alley” this morning and that is not far from the truth.  These south central storms impacted both coasts and areas in between, decreasing activity for a number of transmitting and receiving stations.  It’s not abnormal for the season but these transitions can be difficult as we try to settle-in to Spring and Summer band conditions.  Paul, N1BUG / WI2XTC, questions, “…why there seems to be a “wall” at somewhere around 2000 miles. Storms inside that wreak havoc here, outside it they seem to have no affect.”  I observed the opposite behavior in recent sessions where close-in storms had little impact while the more distance systems resulted in a wash-out.  Its just one of the intricacies of propagation at medium wave.

Geomagnetic conditions continue at quiet levels but a forecast coronal hole is expected to upset the balance. As typical, however, the impact is behind schedule.  The Bz is pointing slightly to the South and has been moving further to the South as the morning progressed.  Solar wind velocities continue at low levels, averaging 325 km/s.  DST values actually look pretty good but I suspect these measurements represent the calm before the storm.




WG2XPJ is once again the only stations to receive trans-Atlantic reports.  Report details can be viewed here.

WG2XPJ -> F59706, G8HUH

Paul, N1BUG / WI2XTC, reported moderate QRN allowing him to decode nine WSPR stations including WH2XGP.

Al, K2BLA / WI2XBV, reported that summertime QRN has reached Florida and appears like it is there to stay.  He decoded four WSPR stations with WH2XXP as his best DX for the session.  Al was decoded by eighteen unique stations with only three at or near a distance of 2000 km.

Neil, W0YSE/7 / WG2XSV, reported that he decoded nine WSPR stations and was decoded by 21 unique stations including KK6AYK, which was a new receive stations reporting Neil in this session and previous.

Rick, W7RNB / WI2XJQ, provided reports for nine WSPR stations and he received reports from 22 unique stations.  Rick’s unique report details can be viewed here.

Joe, K9MRI / WI2XUL, received his grant this morning.  The bullpen is currently empty so hopefully we will see some additional information on the next step for the R & O very soon.

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

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

Roger, VK4YB, indicates that “Noise was a little higher than yesterday, Another “Bactrian” with the first hump centred at 08:00z and the second at 11:40z. The 1st hump favours E to W, and the 2nd W to E.”  Roger provided reports for WH2XXP and WH2XCR.  He received reports from JA3TVF, N6SKM, VE7BDQ, W7IUV, WI2XBQ, WE2XPQ, and WH2XCR.

Ward, K7PO / WH2XXP, received reports from 53 unique stations including  VK4YB, VK2XGJ, ZL2BCG, and ZL2AFP.

Larry, W7IUV / WH2XGP, reported that his transmitter “tripped off” again overnight without any obvious explanation.  Even so, he provided reports for nine WSPR stations and he received reports from 34 unique stations including ZL2AFP.  As W7IUV, Larry provided reports for eleven WSPR stations including VK4YB.

I was “CW only” through this session, beginning with some activity earlier in the day and making a few seasonal measurements from around the area in the afternoon.  As expected relative field strength is down about 3 dB from Winter measurements as trees and shrubs have become green again.  I continued to call CQ through the evening as I was working on chores, listening on wireless headphone, and shutting down around 0200z.  Noise was rapidly increasing as the evening progressed and storms were a possibility overnight so I secured the station.  More storms are possible this afternoon and evening.  Its my intention to continue this operating pattern for the foreseeable future in order to establish “what is going on where” on the band ahead of the myriad of band plan recommendations expected to be put forth in the near future.  There have already been a few “nutty” recommendations made from the peanut gallery.

South 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, experienced a down session but many of his results were likely caused by the storms on the mainland impacting operator activity.  Eden provided reports for three WSPR stations and he was reported by seven WSPR stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, experienced a similar session to the previous with excellent coverage along the West coast of North America.  Laurence provided reports for VK4YB and shared two-way reports with WH2XCR.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, experienced the return of JA reports but it was a complete wash-out for the eastern two-thirds of North America.  Merv provided reports for ZF1EJ and shared two-way reports with VK4YB and WE2XPQ.  He received reports from VK2XGJ, ZL2AFP, ZL2BCG, 7L1RLL4, and JE1JDL.  DX report details can be viewed here.

WH2XCR 24-hour WSPR activity
