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

Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

More big noise in North America but some long haul paths improve as domestic openings were mixed

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.

This session was characterized by another large storm system ranging from Mexico through the Great Lakes region into Canada which was reported to create noise problems into New England and probably other areas not yet reported.  Propagation was also down and WI2XBQ, located in northern California, indicates that his reports were down by as much as 10 dB compared to last night which was a session that I considered to be very poor.  The trans-Pacific path from North America remains poor but perhaps slightly better than the previous session as VK4YB was reported in the Pacific Northwest.  The path from VK to JA was also improved over the previous session.

11-hour North American lightning summary


Geomagnetic conditions are active due to a geoeffective coronal hole.  The Kp is reported at generally elevated-quiet levels at the moment although a few indicators that comprise the Kp that located at higher latitudes indicate that the K-index has reached storm levels.  The Bz is currently pointing to the South although quite a bit of variability has been observed overnight.  Solar wind velocities are down, averaging near 485 km/s.  DST values have decreased to the center line and even lower, into negative territory.



John, WA3ETD / WG2XKA, was QRV and provided the following comments and statistics:

“Very heavy QRN throughout the session.  All activity here was confined to the east and near Midwest.  XKA heard five and was heard by 19, with the best DX being VE6XH in Alberta.”

Ernie, KC4SIT / WI2XQU, reported a good night from North Carolina and submitted these comments and statistics:

“WI2XQU reports antenna improvements, both send and receive. The transmit antenna, 3 ele inverted L cut for 160m was raised from approximately 60 feet to 80 feet by David Day N1DAY. David also reconnected the listening antenna, also an inverted L and also extended the horizontal length. The antennas use the same ground system and are side by side, offering a parasitic effect.

Thunderstorms were easily heard last night but I still spotted 8 unique stations and had 19 unique stations spot me.  Overall, it was a good night for me.”

Neil, W0YSE/7 / WG2XSV, reported a tough session from the Pacific Northwest and he provided these comments and statistics:


Dave, N4DB, reported that it was a “reasonably quiet” night in Virginia.  He decoded seven WSPR stations including ZF1EJ who was his best DX at a distance of 2024 km.

Al, WD4AHB, reported that “In keeping with the “May Madness” theme, today it looks like I’m down to the Final Four. I hope not!  I have reverted to using my PA0RDT-Mini-Whip©, but I think conditions were working against me.”

Trans-Pacific openings were slightly better.  Report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, reported, “low QRN to start the session but building up later. Storms forecast for the next few days so receiving is going to be a challenge. A return of some TA spots and VE6XH scored a double two after his double blank yesterday. Larry, Laurence, and some JAs joined in. Thanks everyone.” Roger’s complete receive report list includes JA1NQI, JA1NQI-2, JA3TVF, VE6XH, W7IUV, WE2XPQ, and WH2XCR.

Larry, W7IUV / WH2XGP, indicated poor conditions in Washington state.  He provided reports for three WSPR stations and he received reports from 21 unique stations.  As W7IUV, Larry provided reports for six WSPR stations including VK4YB.

My activity was minimal during this session due to anticipated overnight storms but I did operate CW starting about one hour and twenty minutes prior to local sunset as I was performing ground wave testing with a station to the South.  Results were good in spite of current geomagnetic conditions and noise levels were relatively low but increased significantly at sunset when I QRT’ed and secured the stations for the night.  I expect to be QRV overnight tonight but will likely miss the next several nights due to overnight storm potential.

Eden, ZF1EJ, provided reports for three WSPR stations and he received reports from fourteen unique stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, provided a report for VK4YB and shared two-way reports with WH2XCR.  The bulk of Laurences reports were located along the West coast of North America and into northern Alberta, Canada.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for ZF1EJ and shared two-way reports with VK4YB and WE2XPQ.  He received reports from VK2XGJ.  QRN and QRT stations likely contributed to overall reduced reports. Merv’s DX report details can be viewed here.
