Current Operating Frequency and Mode

WSPR2 474.2 kHz + 1590 Hz, 15% duty cycle

Quiet geomagnetic conditions give way to many trans-Atlantic reports; Domestic openings were ‘OK’; High activity levels continue

– Posted in: 630 Meter Daily Reports, 630 Meters

Quiet geomagnetic conditions and generally quiet terrestrial weather (excluding precipitation static!) resulted in reasonably good domestic conditions that ultimately meant very good trans-Atlantic conditions.  Trans-Pacific openings continue to hang on later than has ever been observed, at least in the modern era.

12-hour North American lightning summary

 

Geomagnetic conditions are extremely quiet with a northerly Bz and solar wind velocity that has finally returned to low level, averaging 370 km/s.  DST values are nominal for the second consecutive day and hopes exist that a strong positive push might allow high latitude openings to Europe to return once again.

Trans-Atlantic openings were the session highlight,  with VE9GJ providing reports to F1AFJ.  WH2XZO was decoded by G0LUJ-1 and WG2XXM was decoded by F1AFJ, F1AFJ/1, F59706, F6GEX, G0LUJ-1, and G3XKR.  The big winner, once again, was WD2XSH/17, who provided reports to G8HUH and received reports from DL-SWL, DL0HT, F1AFJ, F1AFJ/1, F59706, F6CNI, F6GEX, G0LUJ-1, G3XKR, G8HUH, G8LCO, PA0RDT, and TF3HZ.  Trans-Atlantic report details for this session can be viewed here.

Roelof, PA0RDT, reported on the RSGB-LF reflector: “Last night WD2XSH/17 produced 31 decodes on 630 meter; SNR ranging from -22 to -27. No other USA stations were found!”

Ken, K5DNL / WG2XXM, reported that he was decoded by 66 unique stations, including LA2XPA, G0LUJ-1, F6GEX, F59706, F1AFJ/1, and F1AFJ.

Doug, K4LY / WH2XZO, reported “G0LUJ-1’s decode was first TA since reducing power 2 dB to 66W TPO and about 1.3 W ERP. Spotted by 43 and spotted 10.”

Rick, W7RNB / WI2XJQ, received reports from 31 unique stations and provided reports to 10 WSPR stations including a single bogus report.  Rick was received by ZF1EJ and indicates it was a pretty good night in spite of the very cold weather conditions.  Rick’s unique report details can be viewed here.

Neil, W0YSE/7 / WG2XSV, provided the following WSPR statistics for his station:

“Hearing 9: VA7MM, VE7BDQ, VE7CNF, WE2XPQ, WG2XIQ, WG2XXM, WH2XGP, WH2XXP, WI2XJQ

Heard by 22:
KA0JWC, N3IZN/RX, N6RY, NO1D, SWL/K9, SWLW7, VA7MM, VE6EGN, VE7AB, VE7BDQ, VE7CNF, VE7EHP, VE7KPB, W0AY, W7IUV, WA3TTS, WA6MPG, WG2XIQ, WH2XAR, WH2XGP, WI2XJQ, WW6D”

Ron, WA4JNX, reported:

“Who was that tuning up around 477 khz? Strongest 630m sig ever heard here. MS ndb was almost as strong as local BH (and that’s saying something),also logged some Canadian and OK ones. Band seems to be in good shape tonight.”

I’m not certain who Ron may have been hearing on 477.  Perhaps a WSPR image?

Trans-Pacific reports details for this session (excluding KL7 and KH6) have been aggregated here.

Roger, VK4YB, received reports from JA1NQI-2, JA3TVF, JE1JDL, and W7IUV.  He provided reports for WH2XGP and WH2XXP.

Ward, K7PO / WH2XXP, received reports from 65 unique stations, including VK2XGJ and VK4YB.

Larry, W7IUV / WH2XGP, received reports from 51 unique stations, including VK4YB and ZF1EJ.  He provided reports for 15 WSPR stations as WH2XGP.  The western receive antenna configuration designated as W7IUV provided reports to 12 WSPR stations including VK4YB.  Larry indicates that he does not believe band conditions are any better and weather is very cold with constant high winds resulting in transmit power being down 10-15% due to antenna orientation changes in the wind.  Receive noise due to wind and snow are also intermittently present but common for this time of year.

I got a late start, firing up WSPR at 0400z and running late this morning, not starting morning CW until 1200z.  My impression of overnight band conditions suggests that openings to the Midwest were strong earlier in the evening, with many of those paths becoming less robust as the night progressed.  QRN was low this morning but distant lightning crashes could be detected, presumably from South and Central America.  My WSPR reception report details can be viewed here and my WSPR transmission report details can be viewed here.

Laurence, KL7L / WE2XPQ, experienced a much better session, transmitting and receiving again after a few days of “receive-only” and a power outage in the previous session that impacted his activity until after 1300z.  Laurence reports a significant amount of wind damage with the main probe, which is currently on the ground.  He is using the backup at this time and indicates that the damage may have occurred a day or more ago.
