Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

Another average night dominated by shorter openings that were slow to develop in North America; 475 kHz mystery carrier continues; Trans-Atlantic openings continue to be missing while trans-Pacific openings are depressed

The details for April 27, 2016 can be viewed here.

Storms persist from the South into the upper Midwest and Canada increasing noise levels significantly as the system continues to progress to the East.  Band openings seemed slow to develop and really never showed a spark.  Openings improved a bit as the night progressed which is consistent with seasonal band behavior.

11-hour North American lightning summary


Geomagnetic conditions have been consistent at elevated-quiet levels through the session.  The Bz has turned around to the North and Solarham reports that the coronal hole previously plaguing band conditions is no longer geoeffective.  Solar wind velocities are down from the previous session, averaging near 450 km/s.  DST values are about the same as yesterday, showing lots of variability at negative levels.




Neil, W0YSE/7 / WG2XSV, reported good transcontinental openings from the Pacific Northwest and provided these statistics and comments:


Dave, N4DB, reported “Not so good here in Virginia, bad QRN this morning only 6 heard with ZF1EJ in as usual and of course XXP. But missing are the regulars who were not on.  Steady carrier on 475 is the strongest signal on 630M.  Slow CW bcn in this morning really hard for me to cpy slow CW in the noise I have it at 476.05.  Hearing perhaps WU4 and a B and a NA — any suggestions so I can try to confirm?  It went silent at 10:17.”

Trans-Pacific conditions were depressed and largely limited to single decodes.  Report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that “QRN was moderately high and propagation took a dive. Only one decode of Ward WH2XXP and one of Ken, WG2XXM all evening. Tx was not much better with just a few decodes mainly from..Larry, WH2XGP, and one a piece from N6RY and WI2XBQ.”  Roger also indicated that Terry, N6RY, sent him a note reporting that Roger was decoded for the first time at his station and more than doubles his previous distance record.  Roger added that it was odd given that the propagation seemed so poor.  He received reports for N6RY, W7IUV, WH2XCR, and WI2XBQ.  He provided reports for WH2XXP, WG2XXM, and WH2XCR.

Ken, K5DNL / WG2XXM, reported that he decoded five WSPR stations and he was decoded by 42 unique stations including VK4YB.

Ward, K7PO / WH2XXP, received reports for 45 unique stations including VK4YB, VK2XGJ, and ZL2AFP.  During the evening Ward indicates that propagation was poor with ZF1EJ as his best DX by 0430z.

Larry, W7IUV / WH2XGP, provided reports for six WSPR stations and he was reported by 28 unique stations.  As W7IUV, Larry provided reports for nine WSPR stations including VK4YB.  Larry indicates that his SWR protection circuit engaged again after recent repairs so he will be investigating.

Joe, NU6O / WI2XBQ, reported  mostly short skip at his station during the evening in northern California.  He added this morning that he was “Heard by 22, only 3 2500 km+. A little W-E prop returned with a spot by WG2XJM, 3647 km. Heard 8, with 5 2500 km+, including VK4YB”

The band was very slow to open but that is not abnormal as the days get longer.  My WSPR receive numbers were better but still comparatively poor and those report details can be viewed here.  My WSPR transmit numbers were normal but looking at the roll off time (the time where the previous 1000-spots begins), it suggests that I had a few less reports than the previous session.  Those report details can be viewed here.  With the high noise level this is probably the new normal for a while.  There might be a CW sked tonight, weather and noise permitting.

WG2XIQ 24-hour WSPR activity


The unmodulated carrier on 475 kHz was back last night and I posted the following comments on the 600-meter research group reflector:

“For the last two nights there has been a strong carrier reported on 475 by stations across the South and East.  The signal is due East of me here in Dallas on several antennas and K4RCG in Virginia was reporting it on a roughly NE / SW line.  The SW line would put it in LA / MS region… I originally wondered if it was XSH/7 working on the
PA and/ or antenna as the signal levels were consistent with what I recall his being on PSK and CW when he was last QRV.  Someone indicated that his assigned frequency was active higher in the band, however.

N4DB, also in Virginia, noted that he was hearing a weak CW signal that was somewhat obscured by the carrier.  I’m wondering if someone is trying to put an NDB transmitter on the air…  Tuning off of the carrier did not reveal a CW signal here, however.

Anyone else hear this signal?  Please have a listen tonight… High QRN in that direction didn’t seem to impact it much here..”

Eden, ZF1EJ, provided reports for three WSPR stations and was reported by thirteen unique stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, indicated at 0705z that there was not much propagation.  Most of Laurence’s reports were limited to the Northwest and southern British Columbia but he did share two-way reports with WH2XCR.  Those details are included in Merv’s report details.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, received reports from VK2XGJ and ZL2AFP and shared two-way reports with VK4YB and WE2XPQ.  He provided reports for VK5FQ and ZF1EJ.  It was another challenging night of hearing Merv’s signal outside of the western portions of North America, where coverage was robust.  DX report details can be viewed here.
