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

Unsettled conditions went too far and absorption increased but not before another decent night of trans-Atlantic reports were registered; WI2XQU granted this morning

– Posted in: 630 Meter Daily Reports, 630 Meters

We may not have reached storm levels but it was enough to create problems on the band overnight and this morning for many.  The evening session began with trans-Atlantic openings although the high latitude openings recently observed were absent.  Trans-Pacific openings were missing as well and even domestic reports in Oceania were struggling.  In North America domestic conditions were normal at lower latitudes but it was obvious that higher latitudes were in for a tough night.  WI2XBV indicated record reports from Florida, however.

There were two main sources of QRN during this session, one in South Central US and the other off the coast of the mid-Atlantic region.  Reports in the East suggested that the Atlantic storm system created a number of problems and Paul, N1BUG, reported almost constant noise during the early evening.  I found the southern storms to not contribute much to my local noise level although a number of individual lightning crashes were observed during my evening operating.

Geomagnetic conditions reached persistent unsettled levels overnight and the bump was just enough to wreak havoc.  The Bz is pointing to the South and solar wind velocities are currently averaging near 600 km/s.  DST values have turned negative for persistent periods.




Trans-Pacific reports were the session highlight and those reports seemed to come earlier in the evening.  F5WK continues to experience good results, receiving reports from WA3TTS, K4RCG, W9MDO, AE2EA, WD2XSH/17 and WG2XPJ.  WG2XKA received reports from DL4RAJ.  WD2XSH/17 received reports from DH5RAE, DL4RAJ, F1AFJ, G0LUJ, G3XKR, and G8HUH.  WG2XPJ received reports from DH5RAE, DL4RAJ, F1AFJ, G3XKR, and G8HUH.  Report details for these stations can be viewed here.

Al, K2BLA / WI2XBV, reported a record night at his station, hearing ten WSPR stations and receiving reports from 35 unique stations.  Al indicates that from his location in Florida, most stations are a long way away from him.  This illustrates how mid and lower latitudes were less impacted in spite of active geomagnetic conditions.

Doug, K4LY / WH2XZO, located slightly further North, reported QRN and more high latitude absorption leaving most of his reports at shorter distances and in southern regions during this and recent sessions. Doug provided reports for ten WSPR stations and  was decoded by 43 unique stations.

Rick, W7RNB / WI2XJQ, reported that propagation shifted back to the upper Northeast with no reports from the Caribbean or southeastern US during this session.  I’m a little surprised by this behavior as most recently North and South openings have dominated during geomagnetically active periods.  That’s an interesting observation and Im glad to have the report.  The high latitude transcontinental path lives!  Rick provided reports to five WSPR stations and was reported by 23 unique stations.  Rick’s unique report details can be viewed here.

Ken, N8CGY, reported that he decoded nine WSPR stations including WH2XXP as his best DX at a distance of 1675 km and best report at -19 dB S/N.  Ken indicates that he decoded Ward for most of the night. Ken’s strongest received station was WG2XKA reported at -11 dB S/N at 0730z and a distance of 601 km.

Jay, KA9CFD, reported best that his “…best  dx overnight was ZF1EJ. A bit disappointing with no decodes from AK,HI and nothing across the atlantic.”

Roger, VK4YB, reported a tough night for propagation and QRN in Australia during this session.  At 1205z he indicated that a  “…large area of storms in South Australia plus some local ones causing heavy QRN.  Ward’s [WH2XXP] signal is only rarely visible and no decodes at this time. Only John, VK2XGJ is providing decodes of my signal.”

Mark, WA9ETW / WI2XHJ, reported that he decoded ten WSPR stations during the session with “no DX surprises.”

Mike, WA3TTS, reported “…Some early T/As with F5WK, then below average conditions to the NW….”

I started WSPR at 1830z after rain vacated the area and I got settled.  My first reports were from W0AIR located in Colorado late in the 2000z hour.  Reports into the Midwest were good prior the local sunset and the band seemed very good through the early evening.  Noise was not a real issue and near CW-level reports from WG2XKA were registered in the mid-evening.  I opted to call CQ on 474.5 kHz CW starting at 0100z and heard a signal that was just out of reach that I felt like was calling me.  I received no reports from a calling station using alternative reporting methods so I am inclined to believe that I am hearing WSPR harmonic carriers in combination with digital receive artifacts in the KX3.  I have now decided to return to using the Yaseu FT1000 Mark V for CW receive as its output is more consistent to what I am used to listening to.  I like that signals tend to stand out on the KX3 but I have experienced a number of these seemingly false signals that I have not observed on the other rig.  Reports overnight were normal although limited to North America.  Received signals here were typical for recent sessions but down from what I would call normal for this time of year.  My WSPR transmission report details can be viewed here and my WSPR reception report details can be viewed here.

Luis, EA5DOM, reported that he has translated the MF/LF propagation article by Alan, G3NYK, that so many of us refer to into Spanish and this version can be accessed here.

Ernie, KC4SIT / WI2XQU, received his grant this morning for 630-meters.  Expect to hear him on the air shortly.

110 MF WSPR stations were observed on the WSPRnet activity page at 2337z.  Activity remained high through the evening.  W1BFA was observed as a possible new reporting station from Maine.  Welcome aboard!

Eden, ZF1EJ, experienced good coverage around North America but the DX magic has ended for the moment as active geomagnetic conditions have set-in.  Eden received reports from 25 unique stations and provided reports for ten WSPR stations.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, began his WSPR2 activity at local dusk, operating at 33% transmit cycle.  I admit that I did not have high expectations for Laurence this session but amazingly decodes were reported by JA1NQI with several coming late in the session.  Laurence also received a few reports from the West coast but his receiving was meager which is very understandable under the high absorption conditions.  Laurence’s JA report details can be viewed here.

Merv, K9FD/KH6 / WH2XCR, was QRT again during this session.  I believe he has guests on the island and may be QRT until their departure.
