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

Noisy session in North America as band ‘goes long’ yielding another night with quite a few trans-Atlantic reports; Trans-Pacific openings continue for WH2XXP; Antenna problems at VK4YB

– Posted in: 630 Meter Daily Reports, 630 Meters

Last year’s report for January 21, 2016 can be viewed here.

Judging from domestic reports, it was a noisy night in a lot of places around North America but more importantly it seems that the band was ripe to “go long” with another strong night for trans-Atlantic reports and particularly in the Northeast.  A few storms in the southeastern US really made a lot of noise and WI2XBV in Florida reported 20 dB over S9 static crashes during the evening.   Its hard to do good radio under such conditions but we push ahead.

12-hour North American lightning summary


Geomagnetic conditions have really bounced around during this session, ranging from quiet to elevated-quiet on a relatively consistent and periodic basis.  No additional unsettled levels have been observed and this coronal hole never achieved storm levels.  The Bz has also been variable, ranging from -2 nT to +3 or 4 nT on peaks.  Solar wind velocities decreased below 500 km/s but period above 500 km/s have been observed through the night.  DST values have been relatively consistent but have continued at negative levels.




Trans-Atlantic openings were numerous once again although I suspect noise impacted the number of reports of Europeans during this session.  Report numbers for both F5WK and G8HUH in North America were down compared to previous sessions.  The following details show stations and they were “heard by”:



G8HUH –> WD2XSH/17






Signal-to-noise report details  for each of these stations can be viewed here.

Ken, K5DNL / WG2XXM, reports that he decoded seven WSPR stations and  was heard by 72 unique stations including the previously mentioned G3XKR plus WE2XPQ and WH2XCR.

Doug, K4LY / WH2XZO, reported that in South Carolina it was a  “very noisy last night.”  Doug decoded  thirteen WSPR stations and was decoded by 43 unique stations.  Doug also noted that this past month has really not felt like typical Winter band conditions.  I could not agree more!

Rick, W7RNB / WI2XJQ, reports that the Midwest yielded a number of reports overnight but signals hit a brick wall towards the South.  Rick provided reports for nine WSPR stations and was decoded by 23 unique stations including KG7GVF, who was a new stations during this session.  Rick’s unique report details can be viewed here.

John, VE7BDQ, reported that he was transmitting only three times an hour and in the five hours prior to 0950z.  His WSPR signals were decoded by 26 unique stations with WH2XCR in KH6 as his best DX.   During this same time frame, he decoded eight WSPR stations with WH2XCR as his best DX.  John indicates that he was QRV until 1600z.

Ernie, KC4SIT / WI2XQU, reported that after the previous session where he decoded WH2XCR for the first time, this session yielded reports for fourteen WSPR stations.  Also as previously reported, Ernie’s Part-5 grant for 630-meters was issued during the previous session and hopefully he will be transmitting soon.

Ken, N8CGY,  reported that he decoded eleven unique WSPR stations overnight and the strongest signal was from WG2XKA at 05:22z.  John’s signal was reported at -7 dB S/N.  Ken also decoded VE7BDQ in CN89 at 07:00z for his most distant stations to date at 1808 km.  The signal report was -27 dB S/N.

Mark, WA9ETW / WI2XHJ, reported just before 0200z that a good night might be just ahead as he provided eleven WSPR decodes in his first hour of activity in spite of high QRN levels.

There was an interesting and cautionary tale reported by Rik, ON7YD.  He was monitoring JT9 and received the following decode:

“2040 -22  0.2 1385 @ 5B4ALJ DK2CH 73”

Did a JT9 QSO actually take place between 5B4 and DK2 and Rik only decoded a small part of the QSO?  He asked the questions on the RSGB-LF reflector and Gary, G4WGT, reported that he observed the same decode and had verified that both stations were real.  After everyone took a breath and considered all of the features of this decode including the fact that no claims for this very impressive QSO had been made on any of the 630-meter reflectors it seems that what likely happened was that DK2CH completed a JT9 QSO with 5B4ALJ on another band and when he began JT9 activity on 630-meters he had not cleared the report buffer from his activity on the other band.  That may need to be addressed in the code, perhaps clearing the report fields when the band changes and re-syncing the transmission cycle to the CQ position.  The take home message here is the old cliche, “if it looks too good to be true, it probably is.”  I’m happy to know that, at least for the moment and until DK2CH claims the QSO was real, a likely explanation has been reached.

Trans-Pacific reported details for this session, excluding KL7 and KH6, are aggregated here.

Roger, VK4YB, reported that, “QRN slightly better tonight, but propagation is down a little. JA beam went high SWR about an hour ago. It’s raining and dark but found the wire is broken at the top of the vertical section. That’s the worst possible place. I will have to start all over again.”  Thats unfortunate news about the antenna wire at the transition to the horizontal section.  Hopefully cooler and calmer weather will prevail soon so that he can fix the problem.  Those junction points can be very tenuous.

Phil, VK3ELV, received reports from JE1JDL and JH3XCU, with a few of JH3XCU’s report coming from the previous session.

Ward, K7PO / WH2XXP, received reports from 74 unique stations including VK4YB and VK2XGJ.

W0AIR was once again providing first reports of my signal during this session.  With the QRN I opted out of calling CQ on CW or JT9.  Receiving conditions were down from recent sessions and my numbers were down accordingly.  Transmission reports were down in many cases as well but with reports from G3XKR and WE2XPQ here at my station its difficult to complain much.  Calling the band long is probably only partially accurate but under the QRN conditions is probably the best one can hope for.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity


There were 113 MF WSPR stations reported on the WSPRnet activity page at 0200z.  W7HGC and the previously reported KG7GVF were new stations during this session.  Welcome aboard!

Eden, ZF1EJ, provided reports to eleven WSPR stations and was decoded by 24 unique stations including WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, had a good session, operating two-receivers with WE2XPQ  using WSPRx software and WE2XPQ/1 using WSPR 2.12 as he retests previous base line measurements for both decoders.  Laurence was transmitting in sync with his 137 kHz activity at 33% transmit cycle.  He received reports from JH1INM and received signals from VK4YB.  Laurence also decoded WG2XXM and WG2XIQ and shared two-way reports with WH2XCR.  His KH6, JA and VK report details can be viewed here.

WE2XPQ 24-hour WSPR activity


WE2XPQ/1 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, had a good night of reports from 7L1RLL4, JE1JDL, and JH1INM.  He shared two-way reports with VK4YB and WE2XPQ and was also decoded by VK2XGJ and WE2XPQ/1.  North American mainland reports were not as robust as recently observed, likely due to high noise levels.  Merv decoded signals from WI2XBV and ZF1EJ but it was just too noisy during this session to reciprocate those reports.  Its very rare for me to not hear Merv yet this was one of those session.  Report details for Merv’s JA, VK and KL7 reports can be viewed here.
