Current Operating Frequency and Mode

Probably QRT tonight and in the morning due to storms in the area

Storms in Oceania result in a lightning strike at VK4YB turning a fun morning somber; Nice evening CW signals from WA2XRM on 479.9 kHz

The UTC amateur registration database is hereEven if you don’t think you will use these bands, REGISTER!  Doing so prevents UTC from future PLC coordination in these bands near your QTH.  While amateur interference to PLC systems is a myth and PLC systems are migrating away from RF, there is no reason to give them a reason to do something weird in the future.

It was a noisy night on 630-meters all over the East with evening storms in the Southeast and along the Gulf coast, a few small storms in the Midwest, and a strong cluster of storms in Minnesota, Wisconsin, and parts of Ontario that continue to be a real problem this morning.  A few evening storms containing lightning were also present but were not a problem by morning.  Isolated storms were also reported to be very strong in Queensland, Australia this morning and VK4YB reported a lightning strike at his station that destroyed his main station PC and possibly other stations components.  It was late and Roger decided to stand down for the night and evaluate the true extent of damage in full sun in the morning.  He and family appear to be physically OK.  I can’t imagine him getting a good night’s sleep.  I certainly wouldn’t.

Geomagnetic conditions were generally quiet through this session. The Bz is pointing slightly to the South this morning but has been variable at different times through the session.  Solar wind velocities have returned to low levels, averaging near 350 km/s.  Australian DST values surged to positive levels while the Kyoto value continues to hug the center line just inside of negative levels.




Paul, W0RW / WA2XRM, was QRV on 479.9 kHz with a CW beacon starting at 0300z from Colorado Springs.  I was fortunate to catch his early start, around 0245z, and made a short recording, shown below (note that there is a bit of pre-roll in this recording that I did not edit out so it takes a few seconds for the signal to show up).  Paul was light but nice copy and would have been a very manageable QSO.  Paul is restricted to 480 kHz with excursions within his margin of frequency error specified in his grant so in the past when we have make CW contacts, we have done so as a split QSO.  Paul indicates that he will offer an attractive opening night QSL for stations completing a QSO with him on the evening of October 15, seen below.  He added that he would not be QRV tonight due to anticipated storms.

Joe, VO1NA, reported that he was QRV on 477.7 kHz CW overnight with 80-watts to the antenna through dawn.  The path to Europe has been open with consistent reports by PA0RDT but band conditions remain very noisy.

Mal, G3KEV, reported a good session at his stations with many reports at distances greater than 2000 km, including eight WSPR decodes from EB8ARZ at a distance of 3149km some of which were at levels consistent with JT9 QSO’s (Thanks to David, G0MRF, for checking the values and reporting on RSGB-LF reflector).

Doug, K4LY / WH2XZO, reported that “The numbers were a little better, 10 and 36, but I think it was mostly activity level was up as neither Hawaii or anything from the northwest is in the log.”

Joe, WA9CGZ / WI2XSV, reported that his WSPR signal was decoded by 33 unique stations which was a new record for Joe.  He added that none of those reports were over  1600 km, however.

Neil, W0YSE/7 / WG2XSV, indicated during the evening that he was listening for JT9 and WSPR with his two-receive, two-antenna system configuration overnight.  He added this morning that he was reported by WE2XPQ in Alaska.

John, WA3ETD / WG2XKA, indicates that he provided reports for eleven WSPR stations and he received reports from 31 unique stations.  His best DX was WB6RQN and WH2XXP.  John added that “…The far west and PNW were totally locked out here.  Noise was moderate during this session.”

Ken, K5DNL / WG2XXM, reported that he decoded eleven WSPR stations and he received reports from sixty unique stations including nine Canadian stations.  He shared two-way reports with WH2XCR and ZF1EJ.

Mike, WA3TTS, reported that he decoded twelve WSPR stations overnight, including  “14 xxp spots best -18 0354 and 30 ZF1EJ spots best -16 0348. Got noisy late.”

Dave, N4DB, reported that he decoded ten WSPR stations through high noise from storms in Minnesota.

Hideo, JH3XCU, submitted this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, reported at 1119z on the ON4KST chat that he was the victim of a lightning strike.  The full extend of damage will be determined in the morning.  Prior to the strike, Roger issued a “Code 2” due to high noise from the storms in his area.  He received WSPR reports from W7IUV and he shared two-way reports with WH2XCR.

Ward, K7PO / WH2XXP, received reports from 57 unique stations including ZL2AFP.  Ward indicates that he was operating a 11.5-watt TPO for about 5W ERP (or 8.2W EIRP!) after recent station changes to get closer to Part-97 power levels.  I suspect he can go much lower and still make the trans-Pacific path on quiet nights.  He made it this night and it was NOT quiet down under.

Larry, W7IUV / WH2XGP, provided reports for ten WSPR stations and he received reports from 41 unique stations.  As W7IUV, Larry provided reports for ten WSPR stations including VK4YB.  Larry indicated that overall band conditions seemed down.

This was a pretty enjoyable session of CW for me that began for at 0009z calling CQ on 474.5 kHz.  At 0200z I had a nice chat with Steve, KF5RY, who has been operating from time to time as WG2XIQ/1, taking advantage of a special feature of my grant.  This also gave me some time to complete seasonal evaluation of the K9AY loop, which has a tendency to change in performance due to changes in ground conditions.  Its dry here at the moment but the termination resistance remains where it needs to be and I could make Steve completely disappear when listening West.  The loop also does a nice job with storm noise, which was relatively high for the eastern half of North America.  I QRT’ed at 0226z for the night and was fortunate to find Paul, W0RW / WA2XRM, beaconing on 479.9 kHz (recording posted earlier).  I started listening with the K9AY loop and then switched to the transmit vertical.  Its a pretty big difference but Paul had  plenty of signals for a relatively comfortable QSO.  Fortunately there wasn’t a lot of QSB, which would have been a game changer.   I resumed activity this morning at 1009z, listening to the West due to continued noise to the North and East.  The mystery signal that I mentioned recently came up on approach to sunrise and was generally originating from the West this morning.

I will be appearing on Tom Medlin’s W5KUB webcast on Tuesday evening, September 26 at 0100z.  The Internet TV show will be simulcast on WBCQ 5130 kHz and my section will last about 20-minutes where I will discuss the UTC notification procedures and topics associated with getting operators new to 630-meters on the air.   I last appeared on Tom’s show in the Spring after the release of the Report and Order.

Eden, ZF1EJ, provided reports for five WSPR stations including WH2XCR.  He received reports from thirty unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, indicates that he is performing baseline testing of his system as he makes repairs.  KL7L was designated as an E-probe while WE2XPQ was designated as the Marconi vertical.  Laurence provided reports for six WSPR stations as WE2XPQ, including VK4YB and WH2XCR.  As KL7L, he provided reports for three WSPR stations including WH2XCR.   He indicates that repair work is ongoing to the Marconi transmit antenna and indicates that things are a mess at the moment.  Today’s evaluations suggest that the “…Aces High L400b probe still has it a couple of dBs on most occasions, though Amrad clone and Marconi were typically within a few dBs with a single turn 10ft active loop down about 5dB.”  DX report details can be viewed here.
