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

Current Operating Frequency and Mode

OFF AIR; QRT Thursday night but back Friday morning by 1100z

Very strong night for domestic activity and reports in North America; Good trans-Atlantic openings, including high latitude path to LA2XPA but DX openings not as good as previous session; JA openings for WH2XCR and WE2XPQ; WI2XRM and WI2XRE granted this morning

– Posted in: 630 Meter Daily Reports, 630 Meters

The summary from January 25, 2016 can be viewed here.

Aside for a few evening thunderstorms in parts of the Midwest which were never heard here in Texas, it was a very quiet night with massive WSPR signals.  Typically when big signals are observed like this, mixing and overload occurs and a large number of phantom reports are generated.  This was one of those nights.  Domestic openings were strong from coast to coast and even low power signals had a chance to be heard on the opposite coast.  DX paths were present but down from the previous session and it may have had something to do with missing operators and QRN in key receiving areas.

12-hour North American lightning summary


Geomagnetic conditions were quiet but perhaps a bit more elevated through portions of this session.  The Bz is currently pointing to the North and solar wind velocities are up just slightly but remaining in the low category with averages near 340 km/s.  DST values continue to average near where they were in the previous session with a few excursions on both sides of unity.  The trend continues to be positive.




Trans-Atlantic openings were less wide spread than in the previous session but high latitude paths to Europe were present again suggesting auroral conditions were minimal.  The following list details stations and who they were heard by across the Atlantic:


G8HUH –> WD2XSG/17




Report details for these stations can be viewed here.

Steve, G3XKR, submitted the following comments about his current stations configuration for G3XKR and G3XKR/7:

“Some words of explanation about the 630m WSPR reporting from G3XKR/7….it’s a parallel stream comparing WSPR 2.12_r3617 (very stable) on a XP machine with WSPRX v0.8 rev3058 on a Win7 machine. Apart from a 630m bandpass filter in the XP stream the receive paths are identical. I’m swapping that over today and will continue the comparison for a couple more days.”

Ken, K5DNL / WG2XXM, reports that he decoded sixteen WSPR stations and was decoded by 67 unique stations  including G8HUH, G3XKR, G3XKR/7, LA2XPA, WE2XPQ, and WH2XCR.

Rick, W7RNB / WI2XJQ, reported much improved band conditions overnight, with coverage in the East, Southeast and South.  Rick provided reports for thirteen WSPR stations and was decoded by 34 unique stations.  Rick’s unique report details can be viewed here.

Neil, W0YSE/0 / WG2XSV, had a nice night of transcontinental openings and a record night overall for his station:

“I believe this is the best TXing session I have EVER had on 630m (at this QTH) being heard by 30 unique stations. There were 2 spots from Eden/ZF1EJ, and 6 from VE4XC. Here are the top 9 by distance….”

Mike, WA3TTS, also reported that this session may have been different compared to the previous session and offered these comments and statistics:

“Not a repeat of the prior evening, but a transcontinental path to the NW still present.  My search by distance results briefly sum up the propagation overnight conditions.”

Ernie, KC4SIT / WI2XQU, submitted comments and statistics for this session and his upcoming plans to be on the air overnight.  Ernie did some local daytime testing at very low power and was received by David, N1DAY:

“Clear skies and moderate temperatures returned to the Flat Rock QTH. First, our station building news. David finished the assembly of the variometer he wanted to try and we connected it to the inverted L antenna used for 160 meters. We made two, low power transmissions yesterday afternoon, one on JT9 and the other on WSPR. Both transmissions were clearly seen and decoded at a pre-arranged listening station. Talking with John KB5NJD/WG2XIQ afterwards, we added 3 equipment for signal improvement, the RigExpert had to be ordered. So we are very close to going online. There are images of the variometer below along with images of the signal.

As far as 630 meter reception here last night, conditions seemed to return to the “Flat Rock” normal of 12 unique stations decoded but I can say now that I was decoded by 1….”

John, VE7BDQ, reports that he was transmitting OPERA8 beacon on 477kHz dial USB (478.500 carrier) every 16min until about 1600z.  He indicates that he has received reports from KU4XR in Tennessee.

Andy, KU4XR, commented on his overnight OPERA listening activity with VE7BDQ on LOWFER:

“WOW !! 630 meters was very good overnight ! Many thanks to John VE7BDQ for working with OPERA OP-8 overnight. I totaled 16 decodes from his station, with 1 deep search decode.. This is the most receptions I have gotten from John on 630 meters to date. 73 to all, and hope to try this again with possibly more stations on the band.. “

Al, K2BLA / WI2XBV, reports a new noise source that has shown up in the middle of the WSPR passband.  He is able to null the signal with his receive loop but in the process he finds that he is also nulling desired stations.

Mark, WA9ETW / WI2XHJ, provided a mid to late evening session report at 0326z as thunderstorms approached his QTH:

“Pretty good start w/11 unique decodes so far, but may have to secure stn if T-storms well to the SW continue tracking this way. (All snow ATM.)”

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

Roger, VK4YB, reports that, “The line of storms across the centre of VK has barely moved in 24 hours and is forecast to remain for several more days. This is restricting reception to VK stations only.” Roger successfully moved a signal out of VK, however, receiving reports from VE6XH and W7IUV.  He was also reported by WE2XPQ and shared two-way reports with WH2XCR.

Phil, VK3ELV, received reports from JH3XCU.

Two new grants were issued this morning, one for Mike, AB1AW / WI2XRE, and  another for James, W4BCX / WI2XRM.  I’ve not had contact with either stations to this point that I recall so I don’t have any information on whether they are ready for air now or what they might be using.  Either way, welcome aboard!

Receiving during this session was great with the only complaint at my station being that so many big signals probably impacted the ultimate signal-to-noise reports for weaker stations.  There were a large number of stations in my receive list overnight with relatively good reports and my reception totals improved on the previous session which was already very good.  My transmissions yielded many CW level reports from coast-to-coast and WH2XCR even began approaching CW levels during one period.  The timing of these openings seems so random that a really strong night will be necessary to complete a CW QSO.  JT9 levels were achieved on this path through the evening.  I had planned on running CW at 0130z but didn’t make it into the shack until later than I expected so I just let WSPR run for the duration.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

WG2XIQ 24-hour WSPR activity


Activity was high during the session with 111 MF WSPR stations observed at 2347z and 116 stations observed at 0200z on the WSPRnet activity page.  It was a good night and there were a lot of stations  on the band.  I suspect that there were numerous new stations but admit that there have been so many that its been a challenge to keep up.  If you are new, welcome aboard and if you have been participating in activities on 630-meters for a while, thank you!

Eden, ZF1EJ, continues to grow his coverage as reports expand into the West.  Eden decoded WSPR signals from seventeen stations and was decoded by 27 unique stations.  He also shared two-way reports with WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, reported that his 472 WSPR activity was likely going to be impacted due to his Opera activity on 137 kHz but his overnight reports look pretty good with more reports from JA1NQI and JH3XCU,  reception reports for VK4YB and two-way reports at WH2XCR.  While most of Laurence’s reports were concentrated along the West coast, he also decoded WG2XXM in Oklahoma.  JA, VK, and KH6 report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, also had a session that looked almost identical to the previous session, with reports from JA at JA3TVF anf JA1NQI as well as unlikely two-way reports from VK4YB who is experiencing extreme noise during this session.  Merv also shared two-way reports with WE2XPQ, WH2XZO and ZF1EJ and was hearing well, decoding WD2XSH/17.  Late reports were recorded at VK2XGJ on the approach to sunrise in KH6.  Merv’s JA, VK, KL7, and ZF1 report details can be viewed here.

WH2XCR 24-hour WSPR activity
