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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Very quiet geomagnetic conditions and relatively quiet band by morning but trans-Pacific openings favor lower latitudes; Domestic openings were mostly nominal for Summer Solstice; K4SV assigned WI2XZB

The details for June 21, 2016 can be viewed here.

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.

Like the previous session, the evening was a bit noisier for many stations.  By morning the number of active storms decreased significantly and the noise floor dropped here by as much as three s-units but while the session was pretty good, I don’t think it was nearly as good as the previous session.

11-hour North American lightning summary


Geomagnetic conditions ranged from quiet to very quiet.  The Bz has been pointing solidly to the North but the most recent reporting period has turned to the South.  I suspect that this is an isolated report, however.  Solar wind velocities are at low levels, averaging near 330 km/s and DST values have recovered nicely, moving to the positive side of the centerline during the overnight period.




Ken, K5DNL / WG2XXM, reported that he decoded five WSPR stations and he was reported by 28 unique stations including WH2XCR, ZF1EJ/1 and six Canadian stations.

Neil, W0YSE/7 / WG2XSV, reported that this was “…Not a great session here. WG2XSV, Heard these 6 stations on my vertical: VE7BDQ, VE7VV, WG2XXM, WH2XGP, WH2XXP, WI2XJQ but Merv/XCR is missing…. Heard by these 10: KR6LA, N6RY, N6SKM, VE6XH, VE7BDQ, VE7VV, WH2XGP, WI2XJQ, WW6D + WH2XCR (my DX) I also decoded XND on 137 kHz several times with a best of -8 dB, using the Eprobe-mini whip.”

Larry, W7IUV / WH2XGP, reported “Very high QRN levels here early last night. Shut down most RX systems because I just couldn’t hear anything.  Loran station down the road effectively has shut me down below 300 kHz. So far little impact on 475.  Before Loran went dormant, they would occasionally give me problems on 160.  Hard to keep 2 megawatts out of all the electronic devices when the tower lights illuminate the inside of your house!”  Larry provided reports for seven WSPR stations and he received reports from 23 unique stations.

Rick, W7RNB / WI2XJQ, provided reports for eight WSPR stations and he received reports from fifteen unique stations.

Mike, WA3TTS, reported that he decoded ten WSPR stations including sixteen transcontinental reports for WH2XGP, best at -17 dB S/N.  Mike indicates Larry was his best DX for the session.

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

Roger, VK4YB, reported that “This solstice session started with early decodes of WH2XXP. Within an hour Ward’s signal had reached -17dB. Merv WH2XCR also reached -17 dB, but that was as good as it got.  The early promise was not fulfilled and the band went into a bit of a slump. Spots to or from North America (Pacific Northwest) never surfaced and the path to Japan was down marginally.”  Roger received reports from JA3TVF, JA1NQI/2, and JE1JDL.  He shared two-way reports with WH2XCR and he provided reports for WH2XXP.

Ward, K7PO / WH2XXP, received reports from 34 unique stations including VK3HP, VK4YB and VK2XGJ.

Dave, K4SV, whose application for a part-5 grant on 630-meters has been in limbo since just after the release of the R&O, has been assigned WI2XZB.  This is new territory for many of us as it was unclear how the FCC would respond, at least in the details, to applications following the R&O.  Hopefully Dave’s application passes through NTIA faster than it was reviewed by OET.

I once again waited for it to get dark before starting up.  It seemed only fitting for what should be the longest day of the year.  The band was noisier than the previous session but reports from across the Midwest and East began immediately following my first transmission.  Reports were down a bit from the previous session but were still very good for the Summer Solstice as many CW level and JT9 level reports were observed.  My transmission report details can be viewed here and my reception report details can be viewed here.

Eden, ZF1EJ, operated a single receive station designated as ZF1EJ/1.  Eden is experiencing high winds on Cayman so the tower which holds the transmit antenna for 630-meters has been cranked down.  Eden has also identified a feed line problem with his main receive antenna on a tower which will require considerable effort to repair but he will get it done.  He provided reports for three WSPR stations overnight while listening with the 160m inverted V.

Laurence, KL7L / WE2XPQ, provided reports for four WSPR stations and he received reports from five unique stations.  He shared two-way reports with WH2XCR.

Merv, K9FD/KH6 / WH2XCR, provided reports for VK5FQ.  He shared two-way reports with WE2XPQ, VK3HP, and VK4YB and he received reports from VK2XGJ.  Merv’s DX report details can be viewed here.
