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

Great propagation and band conditions return!; VE7SL and ZF1EJ complete first JT9 QSO; VO1NA QRV 477.7 kHz CW; JA and VK openings continue for the western US and Pacific; WI2XQU prepares for first night of transmitting!

– Posted in: 630 Meter Daily Reports, 630 Meters

The summary from January 24, 2016 can be viewed here.

After one of the worst sessions in recent memory many stations were rewarded by incredible openings and quiet (or quieter) band conditions.  It was good timing because this Winter has been wasting away and before we know it Spring and Summer will be here.

12-hour North America lightning summary


Geomagnetic conditions and metrics have all returned to quiet levels.  The Bz is pointing to the North and solar wind velocities are low, averaging 310 km/s.  DST values have returned to near unity and exhibited stability through the session.  Lets hope for a big push into positive territory in the coming days.




Big congratulations go to Steve, VE7SL, and Eden, ZF1EJ, who completed a first-time JT9 QSO overnight between ZF1 and anywhere else in the world.  This was also Eden’s first two-way QSO on 630-meters.  Steve reported:

“…Hard to believe he is just at 32W output. We started at 0418Z and I received my report on his 4th xmsn and from that point, every xmsn both ways was a solid decode. We could have chatted away all night by the looks of it!  DXCC #3…97 to go :-))”

Steve provided the following screen capture showing some of the QSO details:

Eden commented:

“…From one of the worst nights, the night before, to one of the best nights last night. Heard 17 and heard by 36 including LA2XPA. VE7SL received all night and even after my local sunrise.Going to be exciting times once I can have 2 way contacts with you US guys.”


Neil, W0YSE/7 / WG2XSV, submitted a screen capture from his receiver in Vancouver, Washington as well as a map of the path from PSKreporter:

Trans-Atlantic openings were plentiful and the path to and from North America was very active.  Note the timings of some of the reports in the detail.  The groupings are interesting.  The following list details stations and who heard them:







WG2XXM –> DL4RAJ, F1AFJ, F59706, F6GEX



Trans-Atlantic report details can be viewed here.

Ken, K5DNL / WG2XXM, reported that he decoded seventeen WSPR stations and was decoded by 65 unique stations including the previously reported DL4RAJ, F6GEX, F1AFJ, and F59706.

Doug, K4LY / WH2XZO, had the good fortunate to be heard in Europe and provided the following session comments and observations:

“Still noisy for winter here with 13 unique decodes despite the QRN. .  Conditions were good with 42 unique stations decoding XZO from Hawaii, VE7, and Germany.  The USA decodes by DL4RAJ are interesting, all taking place in a 24 minute period!”


Phil, VE3CIQ, had a strong session including transcontinental openings to WH2XCR.   Phil submitted the following comments:

“Pretty good conditions , or did the noise just back off a bit.  Having to adjust the antenna before every session lately-  ZF1EJ- VE7SL congrats on JT9 contact. Eden,  I will be looking for you for an encore.”

Neil, W0YSE/7 / WG2XSV, reports:

“Was spotted by wa3tts 11 times this session with a best of -22. That *might* be a record…Heard by 26 with these being those over 2000 km distance.

It was fun to watch the chat page and my JT9 screen as the historic event between ZF1EJ and VE7SL unfolded. Only saw SL on my screen however.   I spotted only 10 uniques stations, but spotted WE2XPQ 76 times with a best of -11. That might also be a record for me….*Way to go* Laurence!!”


Mike, WA3TTS, reported good band conditions and submitted the following detailed statistics and comments:

“14 spot from ZF2EJ, early spots (0000~0100 hours) antenna was NE EWE, later spots NW EWE with ZF1EJ direction more or less in antenna pattern null zone…”


Mark, WA9ETW / WI2XHJ, reported good conditions in Wisconsin at 0500z, decoding thirteen WSPR stations, his best report being ZF1EJ and VE7SL.  WG2XXM was up to +11 dB S/N.  This morning Mark added that he decoded two more WSPR stations overnight, bringing his total to fifteen WSPR stations for the session which he indicates was not a record for his stations.  Mark added, “No really long-haul DX; ZF and PNW best. Good to hear about JT9 success.”

Rick, W7RNB / WI2XJQ, reported that the best propagation for his station during this session was in the Northeast and Southeast.  Rick provided WSPR reports to ten stations and was decoded by 38 unique stations.  Ricks report details can be viewed here.

Ken, SWL/EN61, located in Indiana reported a personal record of nineteen WSPR stations decoded overnight.

Ernie, KC4SIT / WI2XQU, reports that he is testing his system and will be on the air tonight.  Initial tests have been promising.  He submitted the following comments and statistics for last night:

“Again I have to say this, my best night of reception yet. Work continues on the station build here and will send photos soon. Last night, though clouds remained, the rain and noise were gone. I decoded 17 unique stations off the non-trap, inverted L. Here are my screenshots.  73 Ernie KC4SIT/WI2XQU”

Trans-Pacific report details for this session, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, reported that “High static restricted Rx spots but propagation was good. A spotlight of signal was wandering around the PNW. VE6XH at 12,592 km was the best DX.  I have not decoded WH2XCR yet, but achieved a 2 way with VE7BDQ. The path to John goes over KH6. How can that happen? I expect Merv will come in nearer our sunrise.  VE7SL, VA7JX, and W7IUV were also receiving, along with WE2XPQ and JA3TVF (on the NE beam!) Almost like old times.”   Those reports of Merv did come on approach to sunrise in KH6.   Roger received reports from  JA3TVF.

Phil, VK3ELV, received reports from JA3TVF.

Ward, K7PO / WH2XXP, received reports from 66 unique stations including JA3TVF and VK4YB on the trans-Pacific paths and the previously reported openings to DL4RAJ and LA2XPA.

Dave, AA1A / WD2XSH/17, reported that VO1NA was operating CW during the evening with a signal of RST 579 at 0048z.  Roloef, PA0RDT, reported on the RSGB-LF reflector that Joe was at CW QSO levels in SSB filter bandwidth using the E-probe for receive.  He provided the following screen capture and audio sample showing just how loud Joe’s signal was in Europe last night.   Geoff, G0LUJ, reported, “Received VO1NA on CW using CW Skimmer Server / Red Pitaya / Wellbrook ALA100LN – 24 Jan 2017 / 0347z on 477.7 kHz, +3dB.”  Luis, EA5DOM, reports that has narrowed his second grabber screen in hopes of  visually identifying Joe’s signal.  Luis’ grabber can be viewed here.


VO1NA CW on 477.7 kHz at PA0RDT


This session was a vast improvement over the previous at my station with a very quiet noise floor and strong signals.  I received a nice report from Bob, WA5JOT, located about two hours to the South in Bryan, Texas.  He was testing an indoor receive loop and an Anan 200D.  He submitted this audio of my WSPR CW ID:


I operated CW for a bit starting around 0115z on 474.5 kHz but completed no additional QSO’s although I felt like I heard a station that might have simply been a pulsing WSPR harmonic.  By 0200z I had returned to WSPR for the night and enjoyed strong signals and CW level reports.  My receive numbers were up significantly, almost by a margin of three-to-one over the previous few sessions.  It was nice to receive reports from F1AFJ and F6GEX as well as the return of two-way reports with WH2XCR, which have been absent for a few sessions.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

Eden, ZF1EJ, had a big night with the previously reported JT9 QSO with VE7SL as well as the report from LA2XPA, a path that has been absent for a few days.  Eden decoded seventeen WSPR stations and was decoded by 38 unique stations.  The two-way path to WH2XCR was also back after recent storms made for the worst session since Eden began operating on 630-meters.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, had good coverage of the West coast of North America and even provided reports for VK4YB.  Laurence received reports from JA1NQI on a path that has been relatively reliable over the previous few sessions.  Reports of Laurence continues until after sunrise at WH2XCR.   Laurence’s JA, VK, and KH6 report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, experienced a return of reports in the eastern US as QRN quietens down significantly.  Merv shared two-reports with ZF1EJ and WE2XPQ and provided reports to WD2XSH/17, WG2XPJ, and WH2XZO.  JA reports return with decodes from JH3XCU and openings to VK have been relatively consistent, providing reports to VK3ELV and VK4YB and receiving reports from VK2XGJ.  Merv also received late reports from VK4YB that began close to Merv’s sunrise.  It looks like situation normal in the Pacific.  Merv’s ZF1, JA, VK, and KL7 report details can viewed here.
