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

Lightning crashes and high noise across much of North America results in an average night at best; DF2JP kite antenna project is go tonight!

The details for February 20, 2016 can be viewed here.

QRN was very bad for a number of stations, some of us were QRT due to the storms at the source while others were only hearing a bit of lightning in the distance.  It was a mixed bag.  It is difficult to assess just how open the band really was but a number of stations were fortunate to hear and be heard by DX stations on a variety of paths.  A view of the lightning map for Oceania suggests that the typically very productive East coast of Australia may be more clear than its been in a few sessions.  Storms in the US central region continue to rage, however.  Neil, W0YSE/7 / WG2XSV, reported that it was a quiet night until around 0530z when the noise increased significantly.

Geomagnetic conditions were quiet with periods of elevated-quiet conditions during the session.  The Bz this morning has pushed significantly to the North although the solar wind velocity is averaging 525 km/s in the high range.  DST values continue to be highly variable in negative territory but the depth of negativity is less than observed recently.




Joe, DF2JP, reported yesterday that he was waiting for good wind conditions so that he could launch a quarter-wave wire vertical using a kite.  Joe indicated this morning that he would begin in the afternoon and let the antenna fly until sunset and evaluate it’s performance.  Maybe it will be windy enough that he can allow it to fly all night (???)  Stay tuned!  We are often not this fortunate to be able to see someone taking this level of initiative in a temporary antenna project.

There has been on-going WSPR-15 work with WD2XSH/15 and WG2XKA but details have been limited at this point.  John, WA3ETD / WG2XKA, reported that  his best reports (-38 dB S/N) were from KU4XR located in Tennessee at a distance of 1238km.   Watch for an analysis in the near future from W5EST.

Trans-Atlantic openings were mildly better than the previous session  with WD2XSH/17 being joined by WG2XPJ and G8HUH in receiving reports.  Report details can be viewed here.

Paul, N1BUG, reported that he completed his antenna repair and modification to allow him to use his best receive antenna on 630-meters but noise was extremely high, making a fair test impossible.  He provided reports for ten stations, however, including a few stations on transcontinental paths.  That’s a good sign.

Doug, K4LY / WH2XZO, indicates that this session was the worst in several days for him, with high QRN and coupled with “flat conditions”, he was limited to providing reports for eleven WSPR stations and receiving reports from 42  unique stations.  The path to KH6 was closed for Doug and he indicated only one VE7 report.

Rick, W7RNB / WI2XJQ, reported that conditions took a major slide backwards during this session.  He provided reports for eight WSPR stations and was decoded by eighteen unique stations.  Rick’s unique report details can be viewed here.

Larry, W0OGH, located in Arizona, reported high precipitation static and an otherwise unproductive night.  He had 224 total WSPR decodes and provided the following statistics for the session:

0200Z    WH2XXP    +1    DM33    120 decodes

0202Z    WH2XGP    -25    DN07    87 decodes

0822Z    WG2XSV    -22    CN85    6 decodes

0904Z    WI2XJQ    -23    CN87    10 decodes

1046Z    WI2XBV    -23    EL99    1 decode

Neil, W0YSE/7 / WG2XSV, reported that, “The QRN static crashes that started coming in last night around 0530z might have had some influence on my reception and transmitting to the east this session. Nothing seen nor heard beyond Utah, SK, or AZ this session.”

Roger, VK4YB, reported, “At last some relief from the QRN. WH2XGP, WH2XXP, WE2XPQ, WH2XCR all in-bound. Best DX out-bound was VE6JY at 12682 km, just ahead of VE6XH. Still no JA.  The low noise has permitted antenna tests to resume. The new loaded vertical has come out the clear winner on VK3ELV’s signal.  Bit of a surprise there but to be fair the beams are pointing away from Phil.”  Roger also received reports from W7IUV.

Phil, VK3ELV, received reports from JH3XCU.  He also had late reports from the previous session which are also included.

Ward, K7PO / WH2XXP, received reports from 58 WSPR stations including VK4YB.

Larry, W7IUV / WH2XGP, provided reports for eight WSPR stations.  He received reports from 47 WSPR stations including VK4YB.  As W7IUV, Larry provided reports for seven WSPR stations, including VK4YB.

I was QRT for the entire session, securing the station by 1700z on Sunday as I was away in the afternoon and the storm forecast was evolving.  I should be QRV again tonight in some capacity.  If noise is not too bad, I might operate a bit of CW but it will depend on noise.  If I can’t hear you calling me there is no need to do it.

Eden, ZF1EJ, returned to air after a few receive-only sessions due to the ARRL DX CW contest this weekend.  Eden provided reports to seven WSPR stations, including WH2XCR and was decoded by twenty unique stations.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, reported no real impact from the HAARP transmissions occurring during the session.  He  received late reports from JA1PKG and JR1IZM and transitioned to 100% TX cycle near sunrise to take advantage of the openings.  He also shared two-way reports with VK4YB and provided reports to WH2XCR who likely had no Internet connection during this most of the session  Merv provided Laurence two reports very late in the session.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity (Note:  late report from JR1IZM not listed)


Merv, K9FD/KH6 / WH2XCR, was nor submitting reports during this session and I suspect that it was an Internet outage at his stations.  He provided two reports to WE2XPQ very late in the session.  Merv received reports from 7L1RLL4, JH3XCU, JR1IZM, VK2XGJ, VK4YB and ZF1EJ.  DX report details for this session can be viewed here.
