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

Geomagnetic conditions begin to recover as high to moderate QRN create problems for some stations; More JT9 activity in British Columbia; Generally depressed trans-Pacific paths but numerous reports for WE2XPQ and WH2XCR

The details for March 24, 2016 can be viewed here.

Storms were widespread  in central and parts of the southwestern US into the Midwest, increasing the noise floor significantly for a number of stations.  Fortunately many of those storms diminished before morning.

11-hour North American lightning summary


Geomagnetic conditions recovered significantly over the previous session, generally returning to quiet levels for most of the session.  The Bz is pointing slightly to the North although solar wind velocities continue to average near 575 km/s.  DST values have improved significantly, returning to near the center line.




JT9 activity continues in British Columbia as Brian,VA7BBG, was looking for a QSO.   He is located quite far North compared to many of the other VE7 stations and based on the ON4KST chat transcript it does not appear that a QSO was completed.  Also present were VA7MM, VE7VV and VE7SL.  John, VE7BDQ, was also present but indicates that he was not setup to operate JT9.

Trans-Atlantic openings continue to be depressed but European stations were heard in North America and WD2XSH/17 received a number of reports from European stations.  Report details can be viewed here.

Paul, N1BUG, reported moderate QRN during the evening that decreased by sunrise.  He reported nine WSPR stations including G8HUH, WH2XCR, and WH2XGP.

Dave, N4DB, reported that he decoded ZF1EJ all night long plus many decodes of WH2XGP,  WH2XXP, and WD2XSH/15.  He lamented never catching DX stations, however.

Rick, W7RNB / WI2XJQ, reported that propagation seemed OK from Seattle but activity was down.  Many of us were QRT for storms.  Rick provided reports for eight WSPR stations and was reported by 27 unique stations including ZF1EJ.  Rick’s unique report details can be viewed here.

Mike, WA3TTS, reported that the “Path to XCR opened well later in the AM hours….”  When asked about his regional QRN, he indicated that, “the QRN was up early and must have abated past 0700…I recall the racing strip QRM line around .635 not very visible early on. By 0400 it was back into light yellow level on the waterfall…brief look around 0900 was strong yellow, and background noise S2~3.”  He provided these statistics and additional comments for the session:

Trans-Pacific openings were depressed, resulting in limited reports but many paths were open briefly.  Report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, indicates that QRN was down but propagation was also down and coupled with two power outages, it was a recipe for disaster.  He received reports from VE7SL and VE7BDQ and provided reports for WH2XXP and WH2XGP.  At the moment it seems that the chain of reports from VE6XH has ended and the comparison experiment is on hold until the path opens again.  Roger indicates that the peaks seemed to occur after sunrise at VE6XH.  The statistics for the session follow:  160m 2 spots, best -20 dB S/N, 630m nil.

Phil, VK3ELV, received late reports from JH3XCU in the previous session.

Ward, K7PO / WH2XXP, received reports from 59 unique stations including VK4YB and JA1NQI.

Larry, W7IUV / WH2XGP, provided reports for 48 WSPR stations and was decoded by nine unique stations including JA1NQI, VK4YB and VK2XGJ.  As W7IUV, Larry provided reports for nine WSPR stations.

Joe, DF2JP, reports that the antenna is up at a reduced height.  Its a tough job to lift a top heavy antenna vertically from a compromised position below the raise point.  He included these comments:

I have the MF antenna up. But I had to fit at 15m height, for more I need at least 2 helper at the ropes. This is for next week.  To the resonance, I now only had to add 16μH to the 100μH of the toploding coil, resulting in an antenna capacity of 965pF !!  Test with the U3 solo yield about 4 -5 dB at the stations <100km in daylight compared to yesterday’s results.  Let’s see what’s going on tonight.

DF2JP MF antenna elevated to 15-meters.


Ron, NI7J / WH2XND, provided a link for this company located in the US that supplies fiberglass telescoping poles similar to those used by Joe, DF2JP in the image above.  This company also has nice prices on vacuum variable capacitors and vacuum relays, far cheaper than what I have spent in the past with Gigavac.  Ron also reported that all openings to his East were cut off during this session, with only five stations reported in the West.

Eden, ZF1EJ, provided reports for seven WSPR stations.  He received reports from 25 unique stations including two-way reports with WH2XCR.

Laurence, KL7L / WE2XPQ, took advantage of propagation that really rebound during this session.  He received reports from JA1NQI, JH3XCU, and VK3GJZ, who indicated in a message to Laurence that he was using an “RFSpace NetSDR+  with SDR-Console and WSPR-X software.”  Zim’s antenna is a random wire attached to an ATU of some flavor and he was receiving from his rural QTH near Traralgon, Victoria.  Laurence also shared two-way reports with VK4YB and WH2XCR.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, received many JA and VK reports during this session from stations like JA1NQI, JA1PKG, JA3TVF, JE1JDL, JH3XCU, TNUKJPM  and VK2XGJ.  Merv also shared two-way reports with VK3ELV, VK4YB, ZF1EJ and WE2XPQ.  He also provided late reports for VK5FQ and there was a late JA opening just after sunrise to JH3XCU and JA1NQI.  Coverage in North America was good with reports from N1BUG in Maine,  and others to the South.  A number of stations were down for bad weather or technical issues, resulting in a number of holes in the South.   Merv indicates that he had a late start and there were a number of active storms to the North of the island.  Its been a real weather roller coaster in Hawaii, ranging from winter weather to summer conditions.   Merv’s report details can be viewed here.
