Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Transcontinental openings observed during the session as geomagnetic conditions continue at quiet levels ahead of a new coronal hole; Path between Oceania and Japan strong; North American path to VK returns; W5EST presents: ”Today’s Blog Puzzle”

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

There is a rumor that has been circulated somewhere on the Internet that claims to allegedly know the UTC notification procedures.  These rumors are lies and seriously jeopardize this process! DO NOT CONTACT UTC TO NOTIFY THEM OF YOUR INTENT TO OPERATE on 472 or 137 AT THIS TIME!  Official procedures are forthcoming – please be patient.  If you find a website or social media post that is perpetuating this bad information, please let me know so action can be taken to rectify the problem.  We can still screw this up!

The primary source of noise for the session was from storms in the Midwest but evening storms were more wide spread than what was experienced by morning.  In practice, listening to the noise was not uncomfortable, which is refreshing for mid-June.  Propagation was slightly improved over the previous session and a number of transcontinental openings were reported.  Long haul reports returned for the trans-Pacific path between Oceania and North America.

11-hour North American lightning summary


Geomagnetic conditions are quiet and the Bz this morning has been stable, balancing along the center line.  Solar wind velocities are elevated and averaging near 450 km/s.  DST values continue to show stability at positive levels.  Solarham is reporting that a coronal hole is moving into position which has been the cause of the elevated solar wind stream velocity.  Its unclear just how strong this coronal will be at this time but Solarham is forecasting unsettled levels for the coming session.  G1 storm levels are not out of the question.




Larry, W7IUV / WH2XGP, provided reports for five WSPR stations and he received reports from twenty unique stations.  As W7IUV, Larry provided reports for five WSPR stations.

Rick, W7RNB / WI2XJQ, reported that he decoded four WSPR stations and he received reports from sixteen unique stations.

Mike, WA3TTS, reports, “stns decoded on 630m last night, ZF1EJ best dx, XZO and XNG other 2 stns rx on my SW EWE antenna.”

Neil, W0YSE/7 / WG2XSV, provided more data from his receive antenna comparison experiment:

“I was RX only again last night for antenna comparisons. Results were similar to last session except for less participation and less propagation. Here are those that were heard here in Vancouver, WA:

“WG2XSV” used the vertical
Hearing: WH2XCR (only 2x), WH2XGP, WH2XXP, WI2XJQ
(absent were WI2XBQ and VE7VV from the previous session)

“W0YSE” was on the attic loop again (12 ft by 5 ft rectangle)

The 4 turn (resonant) loop heard XXP about 5 to 8 dB weaker than the 40 ft top loaded vertical. I want to add another turn to the loop and see what happens. There was a big improvement when I went from 3 turns to 4 turns. Each turn adds about 34 ft wire. “

Hideo, JH3XCU, provided these tables detailing VK -> total JA DX and VK -> JA peak S/N for the session.

Roger, VK4YB, reported that “QRN was surprisingly high considering there was nothing close on Blitzortung. Domestic signals were subject to heavy QSB.  At one point my reports from VK stations was so poor I thought I had an antenna fault, but it was just condx.  The path to Hawaii improved a little but it was still weak. Ward, WH2XXP, got his signal through on several occasions and the best was -23dB.  The path to Japan was holding up well with Tadashi, JA1NQI/2 getting the most consistent signal.”  Roger received reports from 7L1RLL4, JA1NQI/2, JA1PKG, JA3TVF, and TNUKJPM.

Ward, K7PO / WH2XXP, received reports from 28 unique stations including VK4YB and VK2XGJ.

I started the session about 20 minutes before local sunset on CW, calling CQ on 474.5 kHz.  I transitioned to WSPR about an hour later at 0226z and noted  that propagation seemed very short with a quick report from W5EST at -22 dB S/N.  Propagation improved over night as noise decreased and darkness settled over all of North America and into the Pacific.  Reports from stations in New England and portions of the East coast were completely missing, however.  My transmission report details can be viewed here and my reception report details can be viewed here.  I did not operate CW this morning as I had in the previous session.
