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

Here comes the storm! G2/G1 and unsettled conditions return, bringing high absorption at mid and high latitudes; Southerly paths dominate the session; JR1IZM new station QRV in Japan

– Posted in: 630 Meter Daily Reports, 630 Meters

The evening session appeared to start strong with solid reports on East and West paths but those appeared to deteriorate as geomagnetic storm conditions took hold, with improvements on paths moving toward the equator.  Noise conditions were relatively low as the lightning map was generally clear in North America.  I observed a buzz on the band in the early evening that I suspect may be the result of the onset of active geomagnetic conditions but I have no real data to support that feeling aside from the timing.  Precipitation static was present in the northeast, as VE3CIQ and WG2XKA report sticky snow and higher noise levels.  Storms in northwestern Mexico were audible this morning but not really presenting a problem during my morning CW session.

High noise conditions continue to be reported by VK4YB in Queensland, Australia this morning.  He provided this time-lapse image of the storm from the previous session – keep your head down Roger!:

Geomagnetic activity reached G2 storm levels, with the Bz pointing to the South and solar wind velocities ranging from moderate to high levels through the session, currently averaging 620 km/s.  DST values continue to show significant decreases and both indicators presented below illustrate the traditional increase before dropping off, perhaps less pronounced than normal but more visible than observed in recent geomagnetic events.  G1 and unsettled conditions are expected through the next session.







Trans-Atlantic openings were more difficult to find during this session as high latitude paths encountered higher absorption.  WD2XSH/17 received reports from DH5RAE, F59706, G8HUH, and PA0RDT.  Report details for this trans-Atlantic activity can be viewed here.

Neil, W0YSE/7 / WG2XSV, reports that my station was his eastern-most DX for this session, with no addition reports East of Montana.  Foggy conditions in the Vancouver area reminded Neil of the ionic fog often encountered during these types of geomagnetic storms. Nevertheless he decoded seven WSPR stations, including WH2XCR and WE2XPQ and he was decoded by fifteen unique stations, including a new station, KI6STW, near San Jose.

Doug, K4LY / WH2XZO, continues to test differences between the Wellbook amplified loop (K4LY) and the Delta (WH2XZO).  Early domestic reports suggest that the Delta was 7 dB better, although further testing is necessary.  Doug indicated that he may change the direction of the antenna today to make additional comparisons.  He added this morning, “With high latitude attenuation and some QRN we were back to early fall levels of numbers, 32 and 11, and SNRs on some paths. but others remained good.”

Trans-Pacific report details for this session (excluding KL7 and KH6) are aggregated here.

Roger, VK4YB, indicates that the recent extreme lightning QRN was more of the same during this session.  He reports that by midnight there was a few periods that were quiet enough to allow a few decodes.  Roger received reports from JA1NQI-2, JA3TVF, VE7CA and W7IUV and provided reports to WH2XXP and WH2XGP.

Ward, K7PO / WH2XXP, received reports from 59 unique stations including a nice opening to JA with reports from 7L1RLL4, JA1NQI-2, JR1IZM in addition to reports from VK4YB and VK2XGJ.

Larry, W7IUV / WH2XGP, received reports from 41 unique stations including VK4YB with good coverage of eastern stations. He received eleven unique stations using the eastern BOG.  Using the western receive antenna and receiver that is designated as W7IUV, Larry reported nine WSPR stations, including VK4YB.

Joe, NU6O / WI2XBQ, reports that he was decoded by 21 unique stations with his best DX being ZF1EJ at a distance of 4707 km. Joe indicates that trans-Pacific openings for his station were only one way, decoding VK4YB sixteen times between 09:06z – 14:20z, representing a very long opening.  Joe adds that even using QRO did not help during this session. (NOTE:  Joe’s report details are not found in the WSPR database due to an ongoing problem with how his location data is either presented or processed.  These reports come directly from his WSPR console.)

Daytime WSPR did not yield much after the 1400z hour, with final reports from KU4XR in Tennessee.  Evening reports began about one hour prior to local sunset and just prior to onset of the current geomagnetic storm conditions.  It was an “OK” night for domestic conditions but a nagging buzz would have complicated any evening CW.  The buzz was gone this morning during my CW session.  Many CW levels reports were registered on one-hop paths but significant QSB was present on longer and northern paths.  East-West paths deteriorated as the session progressed.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.


WG2XIQ 24-hour WSPR activity


104 MF WSPR stations were observed at 0230z on the WSPRnet activity page.  KE5YKP near Houston, Texas and KI6STW near San Jose, California were observed for the first time.  Welcome aboard!

Eden, ZF1EJ, provided reports for VE3CIQ, VE3EFF, WD2XSH/15, WD2XSH/17, WG2XIQ, WG2XKA, WG2XXM, WH2XCR, WH2XGP, WH2XXP, WH2XZO, WI2XBQ, and WI2XBV.  Report details for these stations can be viewed here.  Eden also listened with his new transmit antenna and provided reports for WD2XSH/15, WD2XSH/17, WG2XIQ, WG2XKA, WG2XXM, WH2XCR, WH2XGP, WH2XXP, WH2XZO, and WI2XBV.  Report details for those stations can be viewed here.

Laurence, KL7L / WE2XPQ, reported VK4YB on a North/South path  which is probably tough under the current high latitude absorption conditions.  Laurence’s report detail for VK4YB and WH2XCR (two-way) can be viewed here.

Merv, K9FD/KH6 / WH2XCR, experienced good results with stations in the eastern US and Caribbean in spite of the East / West paths being somewhat compromised due to the current geomagnetic conditions.    Similarly he received reports from JA1NQI-2 and JR1IZM to the West.  The path to Oceania resulted in reports from VK2XGJ and two-way reports with VK4YB in spite of the very high noise level in eastern coastal Australia.  Merv’s DX report details for this session can be viewed here.
