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

More big trans-Atlantic openings including first time crossing for WI2XBV; TI3/W7RI and XE2EJ providing reports and hearing well; Trans-Pacific openings favored North America –> JA path over path to Oceania

The details from February 27, 2016 can be viewed here.

It always works out when the really big openings occur and DST is elevated that there are storms here that keep me and others off the air.  But its good to see other stations finding success and the big DX reports are good for what we do.  I’m sure it was noisy for many listening in the South and Midwest as big storms ramped up in northeast Texas and southeastern Oklahoma across to Mississippi.  The lightning map was otherwise clear in North America.

Geomagnetic conditions were quiet but perhaps slightly more active than the  previous session.  The Bz is pointing slightly to the South but solar wind velocities are currently very low, averaging 350 km/s.  DST values moved into positive territory with both indicators at relatively stable levels and persisting near the center line.




Dave, AA1A / WD2XSH/17, reported that WG2XSB was QRV on 471 kHz with aural CW.  Ken, SWL/EN61, located in Indiana also reported seeing XSB’s signals in Argo at 0151z.

Trans-Atlantic WSPR openings were very good with Al, K2BLA / WI2XBV, reported for the first time across the Atlantic by EA8/LA3JJ.  Reception reports for European stations also returned with a number of stations being reported here in North America.  Report details can be viewed here.







F6GEX –> WD2XSH/17

PA0O –> WD2XSH/17



The parenthesis enclosing G0MRF’s listing above for WD2XSH/17 denotes a rather interesting report provided by David via email that involved a bit of detective work.  He explains:

“I received WD2XSH/17 last night via the remote WSPR receiver which appears as SWUKSDR on the WSPR map.


What was interesting is that the WD2XSH/17 callsign was not decoded by the software, but a quick check on the distance and QRA locator soon revealed who it was.  Without the call the spot was not uploaded to WSPRnet, but it was nice to see the USA locator in amongst the Europeans.  I’ll contact the owner and let him know the problem.”

Al, K2BLA / WI2XBV, had a great session for DX and he provided these comments and statistics:

“A banner nite for me. hrd by 39 including XE2EJ, TI3/W7RI and EA8/LA3JJ. Hrd 11 including XCR. if I include ZF1EJ and the VE’s that hrd me with the W’s I was hrd by 5 DXCC entities. Maybe some day I can QSO DXCC entities….yup maybe some day….”

Doug, K4LY / WH2XZO, also had a big DX night:

“630M- the DX band!   Six countries are in last night’s log: TI, EA8, XE, ZF, VE, and K.  Never expected anything like that!  The totals were 55 who decoded XZO and 14 unique decodes.”

Paul, N1BUG, reported, “The session started off looking very good but went down hill from the start with decreasing transatlantic propagation and increasing QRN.  LA8AV single decode just after sunset, first decode of the session for new station, country and my highest latitude path to date. Several G8HUH decodes early.  Transcon was good with WH2XGP peaking -6, WI2XJQ, WD2XSH/20. Five WH2XCR decodes with best -22. Heard 16 stations this session.”

Phil, VE3CIQ, reported a very quiet night, decoding nine WSPR stations and receiving reports from 34 unique stations.

Rick, W7RNB / WI2XJQ, reported a very good night in spite of snow fall which likely increased precipitation static during the session.  Rick received reports from 36 unique stations including “all four corner of the US plus Baha and ZF1EJ”.  He provided reports to seven WSPR stations, including WD2XSH/17 in what was a very active, WSPR passband in the Pacific Northwest.  Rick’s unique report details can be viewed here.

Neil, W0YSE/7 / WG2XSV, reported a strong session of transcontinental reports.  He submitted these comments and statistics:

“A pretty decent session for me with a lot of easterners hearing me. KK6YTS (NV) is a new one I believe.

33 Unique spotters (by distance):

No copy of XIL’s QRSS12 on 2200m, but got decodes of XND and BDQ on LF.”

Trans-Pacific opening favored the path to Asia from North America as lightning-rich storms dotted Australia and surrounding areas. Report details, excluding KL7 and KH6, can be viewed here.

Roger, VK4YB, had no reports for other stations during this session suggesting either high QRN from storms in his region or an upload problem.  He received reports from VE6XH for the only Australia to North America crossing for the session. UPDATE: Roger indicates that he has Internet problems.  He sent the following note and his receive data can be viewed here.

“My internet has failed at home. I am sending this from my work computer.  My RX log for last night is attached.  The only DX received were  WH2XXP and WH2XCR.  I deleted the VK stations in the log.

630m/160m test result with VE6XH:      160m 7 spots, best -17,  630m  3 spots, best -27.

I was operating blind of course…. so frustrating!  Last time I lost internet it took them 2 weeks to fix it.  I bet that happens this time also AND the band will open big time.  Which is good news for everyone else!
If I see big signals coming in, I will change to JT9 on 474.2 + 1380, just below the WSPR band. I will not be able to co-ordinate a QSO on the ON4KST net.  I can only hope someone will see a JT9 transmission and investigate.”

Ward, K7PO / WH2XXP, received reports from 78 WSPR stations including VK4YB (see above), VK2XGJ, ZL2AFP, JA1NQI, JA3TVF, JR1IZM, and the previously reported EA8/LA3JJ.

Larry, W7IUV / WH2XGP, provided reports for sixteen WSPR stations and received reports from 64 unique stations including JA1NQI.  As W7IUV, Larry provided reports for ten WSPR stations.  Larry indicates that his reports from TI3/W7RI represent a new DXCC entity for him on 630-meters, bringing his 630-meter DXCC receive report total to eleven while amazingly using a 44-foot tall vertical.

Rudy, N6LF / WD2XSH/20, received reports from JA1NQI and JR1IZM.

An application for a 630-meter Part-5 grant has been filed by Jason, W6IEE, for PSK, FSK, and CW between 465 and 478 kHz.  There are currently four applications in the bullpen awaiting action.  Two of those have been associated with call signs and forwarded to NTIA for approval.

Clemens, DL4RAJ, sent a nice note detailing his receive antenna system which has produced very big results in many sessions this season.  This note was precipitated as a result of a recent discussion and speculation about his receive capabilities by stations  that had received reports from Clemens.  His description and overhead view of the antenna follows:

“I just wanted to let you know that my antenna is no Beverage but a horizontal fullsize halfwave dipole at very low height, shaped as horizontal V (90 degrees) with the apex pointing to north fed by about 45m balanced open wire feeder.  See attachment and for a closer look at the site with google earth see also  http://k7fry.com/grid/?qth=JN68KJ79WJ .  The open wire balanced feeder is drawn in yellow,the dipole antenna in red. It has 2x155m, but the height agl is very low,i.e. 7-8m at the feeding point and ca. 15-20m at the ends.  EZNEC predicts a nearly omni-directional pattern in all elevation angles, slightly favouring even NE-SW see screenshots (Y-Axis is N, X-Axis is E in the 3D-Plot).  But it’s 45m meters away from my the houses which minimizes noise.  After comparison with the other best hearing WSPR DL stations,which are DH5RAE and DL0ABR I’ve come to the conclusion that it might be the quiet location AND the topography of the terrain which makes the difference.

Below the antenna the ground is sloping into NW direction and later it passes into a valley. DH5RAE and DL0ABR have also full size dipoles 40m off the house, at much more height agl than me ,i.e. 13-40m and in a wood. They do spot TA WSPR stations quite good,but I seem  to have always an edge. RX is mostly a Perseus,and at times an old Telefunken receiver or my IC-7800 on the same antenna for comparison (“DL4RAJ/2”).

Recently I’ve re-erected my K9AY in the garden which is still by far too noisy (man made noise from my house) to compete with the dipole. I’ll try to insert several common mode chokes into the coax and the DC feeding line and shall see if this reduces noise sufficiently.”

I was able to operate for a little over an hour before being forced to QRT by pop-up storms during the evening.  While the risk continued through the night there were no additional storms.  The same conditions exists today but I am hoping that the storm chances are revised to such low levels that I can operate overnight without fear of a pop-up storm.

Band activity was very high, with 130 MF WSPR stations observed on the WSPRnet activity page at 0200z.  This total does not include other band activity unassociated with WSPR.

ZF1EJ 24-hour WSPR activity


Scott, TI3/W7RI, returned for this session, providing first time reports for WH2XGP, WH2XXP, WH2XZO and WI2XBV.

TI3/W7RI 24-hour WSPR activity


Fernando, XE2EJ, provided reports for eleven WSPR stations around North America including WE2XPQ and WH2XCR.

XE2EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, took advantage of great openings to Japan with reports from 7L1RLL4, JA1NQI, JA3TVF, JA8SCD5, JE1JDL, JH3XCU, and JR1IZM.  The path to VK was open, as Laurence provided reports for VK4YB but could not reciprocate due to storms in Australia.  Laurence shared two-way reports with WH2XCR and had nice coverage of the western region of North America and received first time reports from XE2EJ on the Baja peninsula.  Laurence’s DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, received numerous reports from N1BUG in Maine as well as WA3TTS, K4RCG, WH2XZO, and WI2XBV on the East coast of the US plus KB0BRY in the North Central US.  He also shared two-way reports with ZF1EJ.  Pacific paths were also good with reports from  7L1RLL4, JA1NQI, JE1JDL, JH3XCU, and JR1IZM in Japan and VK2XGJ and ZL2AFP in Oceania.  Merv also provided reports from Roger, VK4YB, who was limited but storms in the region.  Coverage of the western region of North America was very solid as well, including reports from XE2EJ.  Merv’s DX report details can be viewed hereUPDATE:  Merv also received reports from VK4YB who has Internet problems.  See Roger’s entry above in the trans-Pacific section.
