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

Trans-Atlantic openings struggle although WD2XSH/17 receives a few 100 mW reports; Trans-Pacific openings begin early with much improved path to Oceania; Mystery signal on 477 reported in Europe; DF2JP kite antenna planned for tonight

The details for March 6, 2016 can be viewed here.

This session was characterized by continued quiet band conditions with propagation that seemed to favor domestic openings for most stations.  The path to Europe was down again on first look but trans-Pacific openings to Oceania have returned in a big way, possibly marking the season shift which favors these paths as Summer in the southern hemisphere begins to wane.  JA paths from North America seem less prolific than recent sessions.  Lightning QRN was not present although KA9CFD in Illinois reported local noise problems during the evening.

The geomagnetic field continues to experience periods of unsettled conditions.  As a general trend conditions seem to be improving as solar wind velocities are now below 600 km/s, averaging 580 km/s for several reporting periods.  The Bz is pointing to the South, however, so this event may not be over.  DST values continues to suggest disturbed band conditions.




Trans-Atlantic openings continue to be depressed although there may be some hope as WD2XSH/17 indicates that he was operating at 100 mW ERP overnight.  He managed a few reports from Europe.  Report details can be viewed here.


Doug, K4LY / WH2XZO, reported good activity and openings on transcontinental paths to KH6 and VE7.  Doug indicates that trans-Atlantic openings were very poor, however.  He provided reports for fifteen WSPR stations and was decoded by 52 unique stations.

Paul, N1BUG, reported that he decoded thirteen WSPR stations including two weak transcontinental reports for WH2XGP on a session that was quiet.

Al, K2BLA / WI2XBV, reported a good night, decoding thirteen WSPR stations and receiving reports from 35 unique stations.  Al indicates that he shared two-way reports with WH2XCR, best report in KH6 at -15 dB S/N.  He also indicates that  he was hearing WD2XSH/17 well at his reported 100 mW ERP.

Ken, SWL/EN61, located in Indiana, reported “good propagation toward the west. 30 decodes of wh2xcr. 6 decodes of ve7bdq … best at -11db.”

Larry, W0OGH, reported that he decoded thirteen WSPR stations (593 session captures!) between 0136Z and 1344z.  He provided the following statistics:

WH2XXP    0136Z    +7        DM33
WG2XXM    0136Z    -2        EM15
WG2XIQ    0136Z    -12       EM12

Neil, W0YSE/7 / WG2XSV, reported a tough night in the Pacific Northwest with these statistics and comments:

“A very poor reception night here in Vancouver, WA this session. I was RX only with two receivers and two antennas and heard only the following:

WG2XSV using the 40′ TLV (Top Loaded Vertical)

W0YSE, using the PA0RDT mini-whip (or Eprobe) at 24 ft

I was hoping to see some JT9 activity so, on a whim, I decided to share my XSV screen using ”Join.Me”. I saw that there were some lurkers checking out my screen, but there was no JT9 activity for them to see

I am hoping also to see some VK’s as we approach equinox. The band seems quiet this morning, although there has been a lot of noise in the evenings this past week or so.”


Mike, WA3TTS, provided a brief report after discovering this morning that he had left a 300 kHz low pass filter in line overnight.  He was hearing well quite late in the session:

Trans-Pacific openings to Oceania have been depressed recently but seem to have rebound in a big way during this session.  The path to JA was also good for some.  Report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, reported zero QRN plus a bonus at his sunset (0818z) with decodes of WG2XXM, WH2XGP, WH2XXP, and WH2XCR in the same transmit cycle, shown below.  Roger added, “Finally the lift in conditions that I have been anticipating as the equinox approaches. The QRN has gone for the time being. Huge number of TP spots recorded in both directions.  630m/160m tests with VE6XH continue, 160m 4 spots, best -21, 630m 9 spots, best -24.”  Roger received reports from VE6JY, VE6XH, VE7BDQ, VE7SL, W7IUV, and JE1JDL.  He provided reports for VE7BDQ, WH2XGP, WH2XXP, and WG2XXM.

“Quadfecta” sunset reports at VK4YB


John, VK2XGJ, indicates that he decoded WH2XXP just after local sunset at 0840z.  John added that he was “Running the old WJ 8718a using the ISB just to be different.”

Ken, K5DNL / WG2XXM, reported that he decoded fourteen WSPR stations and was decoded by 66 unique stations including VK4YB and WE2XPQ.

Larry, W7IUV / WH2XGP, provided reports for thirteen WSPR stations and was decoded by 54 unique stations including JA1NQI, VK2XGJ, VK4YB, and ZL2AFP.  As W7IUV, Larry provided reports for nine WSPR stations.

Ward, K7PO / WH2XXP, received reports from 75 unique stations including  JA1NQI, JA3TVF, JH3XCU, JR1IZM, JE1JDL, VK2XGJ, VK4YB and ZL2AFP.

John, VE7BDQ, provided reports for 41 WSPR stations and was decoded by eleven unique stations including two-way reports with VK4YB.

Ken, SWL/EN61, located in Indiana, reports that he was able to find a null on the “racing stripe” that is observed in WSJTx waterfalls around the world near 475.635 kHz.  Apparently from his location in northwest Indiana while using the 7-inch loop stick antenna the signal was on a line to the Northeast  and down to Louisiana.  In the past, Eric, NO3M / WG2XJM, has found that the signal peaks to his West from western Pennsylvania and a quick check around the azimuth here this morning at 1000z produced no null, suggesting that the signal is re-radiating in my local area.  If any one on the West coast could shoot a bearing back to the East, perhaps a crossing point could be found.  Its an interesting feature that will probably remain a mystery for a long time to come.

Martin, G8JNJ, reported a mystery signal on 477 kHz that looks like JT9 as far as modulation is concerned but the frequency excursions suggests something else or perhaps someone has serious problems with frequency stability.  Martin indicates that the signal was strong at his QTH.  My guess is that someone was playing around with JT9 or they have a serious problem with their transmitter.

Joe, DF2JP, reports that his wind is perfect today for his kite antenna and he hopes to be QRV by 1730z which is his sunset.

Bruce, K1FZ, posted this link on the Topband reflector which might suggest that propagation may improve (or the opportunity exists) at the end of a “Solar storm”.

I thought the evening session was strong with low noise but QSB was active and many signals seemed to vary significantly over the span of a two-minute WSPR cycle.  This behavior is a feature that makes these nights fun – you cast your net and drag something in.  Domestic band conditions were strong and signals around North America were quite serviceable.  This behavior is typical for unsettled band conditions as we have been  experiencing.  Around 0230z I called CQ on JT9 for a few minutes but evening band conditions were just too disturbed. and I was not even receiving reports on WG2XSV’s receiver that had been setup for JT9 overnight.

This morning I was awake early so I called CQ for a bit on 474.5 kHz CW at 1030z.  Nearby WSPR signals were very strong, in fact, one signal in particular may have an unhappy match and their PA may have been reacting.  It could have simply been overwhelmingly strong signals and re-radiation as I had a number of harmonics reported on my signal at times overnight recently.  No additional QSO’s were reported from my CW activity this morning.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

Eden, ZF1EJ, returned to air after being in a “receive-only” condition this weekend due to his station’s participation in the ARRL DX phone contest.  He seems to have returned in a transmit-only capacity, suggesting that a cable may not have been plugged in or something like that.  He was reported by 34 unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, seems to be doing pretty well in spite of elevated attenuation and absorption.  He provided reports for VK4YB and shared two-way reports with WH2XCR.  Reports extended as far South and East as WG2XXM.  DX report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, had a nice session with several early JA reports followed by a number of late reports near sunrise, including reports from 7L1RLL4, JA1PKG, JA1NQI, JE1JDL and JH3XCU.  Oceania was also well represented with reports from VK2XGJ, ZL2AFP, and two-way reports with VK4YB.  Eastern two-way reports were achieved with WI2XBV and WH2XZO and there were a number of reception reports from the region.  DX report details can be viewed here.
