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

A few periods of unsettled geomagnetic conditions during the evening; Trans-Atlantic reports move South along coast and into Caribbean; Trans-Pacific openings improve; DF2JP short antenna experiment

QRN was relatively low in Texas in spite of big storms in Mexico during the evening and overnight period.  A few additional storms off of the southeastern coast of US and northeast Texas appeared by morning.  At best these storms provided the odd lightning crash but it was my impression that communications were not largely disrupted.  Seasonal noise levels are increasing and I doubt we will not have another truly quiet night before late next Fall.

Geomagnetic conditions continue to experience periods of unsettled conditions as the Bz continues to point to the South and solar wind velocities are averaging near 515 km/s.  DST levels are highly variable again after yesterday’s session suggested relatively high stability was returning.  In short, the DST values continue to suggest that disturbed conditions dominate.




Trans-Atlantic reports spread South along the East coast of North America and into the Caribbean for the first time in over a week.  Report details can be viewed here.




Paul, N1BUG, reported receiver problems during the session and indicates that his data should not be considered complete.  He provided reports for thirteen WSPR stations including “a single weak report” for WH2XGP.

Al, K2BLA / WI2XBV, reported a quiet night in Florida, providing reports for twelve WSPR stations and receiving reports from 31 unique stations including two-way reports with WH2XCR.

Neil, W0YSE/7 / WG2XSV, reported good transcontinental openings overnight as well as a bit of JT9 with these comments and statistics:

Rick, W7RNB / WI2XJQ, reported ” Back to good conditions, covering the East fairly well, and ZF1EJ. Both Alaska and Hawaii round out the coverage. ”  He provided reports for nine WSPR stations and was decoded by 29 unique stations.  Rick’s unique report details can be viewed here.

Doug, K4LY / WH2XZO, reported that quiet conditions returned to North Carolina.  He submitted these statistics and comments:

“On a quiet night here, the 16 unique decodes tied 2nd most ever.  Used bidirectional loop until 3 AM and WNW favoring delta afterward hoping to hear beyond Hawaii.  The 37 spots of XZO was mediocre and little changed from the previous night. The cold fronts forecast for the next week may keep the QRN away.”

Ken, SWL/K9, located in Indiana reported a JT9 CQ reception from VE7BDQ:



Mike, WA3TTS, reported that propagation improved over the previous session with several dozen decodes of WH2XZO plus other  stations overnight.  Mike, provided these comments and statistics:

Trans-Pacific openings seemed to have improved further from recent previous sessions.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, posted links to two tables showing US -> JA DX totals and US -> JA peak S/N for the session.

Roger, VK4YB, experienced a return of JA reports during this session.  He adds, “QRN started lowish but rapidly rose to bad. Transmission reports were quite good but no reports were received from stations South of Larry, W7IUV.  Laurence, WE2XPQ, did not hear me until I switched to the JA beam. The path must be a little skewed. 630m/160m comparisons with VE6XH. 160m 6 spots, best -14, 630m 15 spots, best -22.”  Roger received reports from CF7MM, VE6JY, VE6XH, W7IUV, JA1NQI, and JH3XCU.  He provided reports for WG2XXM, WH2XXP, and WH2XGP.

John, VK2XGJ, reported that he had has high noise and no early reports and possibly no DX reports at all for the second consecutive session.  As a result he is switching back to the Kenwood R5000 receiver.

Ken, K5DNL / WG2XXM, reported that he decoded fifteen WSPR stations and was decoded by 55 unique stations including VK4YB and ZL2AFP.

Larry, W7IUV / WH2XGP, provided reports for sixteen WSPR stations and was reported by 45 unique stations including VK4YB.  As W7IUV, Larry provided reports for nine WSPR stations.

Ward, K7PO / WH2XXP, received reports from 63 unique stations including VK4YB, ZL2AFP, and JA1NQI.

Joe, DF2JP, reported that as he waits for favorable wind conditions for his kite antenna experiments to continue he is testing a short, 12-meter tall vertical that uses a 58-meter top loading wire.  Joe indicates that the antenna capacity is 340 pF, requiring 330 uH of inductance to resonate the system at 475.6 kHz.  He adds that using just 90 mW, which equates to less than 1 mW ERP, he reached 32 unique stations with LA8AV at a distance of 960 km.  Joe will likely have more data tomorrow.  QRP experiments with simple antennas can be fun at these frequencies.  And surprising.  A few pictures of his system follow:

I got a late start on this session, making first transmissions at 0102z.  Reports were relatively good but with disturbed conditions it was obvious that I would likely be best served by running WSPR only and monitoring the situation for possible openings and QSO opportunities depending on who was on the air.  Propagation improved overnight but noise was higher by morning.  Unique stations received were high but my decode totals for the pool of transmitting stations seemed a bit down.  WSPR transmission report details can be viewed here.  Reception report details can be viewed here.

W1AW was quite loud again last night but there was little 160-meter band activity when I was listening aside of a few JT65 stations.  I suspect activity increased as sunrise in Europe approached.  This morning JH1HDT had a building signal on 1824.5 with few callers.  I would have called but time was short.  It is good to see the activity and the opening.

Eden, ZF1EJ, received a report from G8HUH during this session after more than a week of no openings to Europe.  He provided reports for 15 WSPR stations and was decoded by 33 unique stations including two-way reports with WH2XCR.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, received reports from JA1NQI this morning and reported VK4YB.  He also shared two-way reports with WH2XCR and coverage in the western portions of North America was pretty typical  I know geomagnetic conditions are poor right now at Laurence’s latitude but its nice to see the JA and VK openings.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, reported strong QRN as storms remain in his forecast.  He added that he had just started WSPR at sunset (0436z) when ZF1EJ was received.  He was surprised to see  Eden in Hawaii so early, especially with the high QRN level.  Merv also provided reports for VK3ELV and shared two-way reports with VK4YB and ZF1EJ.  He received reports from 7L1RLL4, JA1NQI, JH3XCU, ZL2AFP and ZL2BCG.  Eastern coverage seems to exceed West coast reports during this session with WI2XBV in Florida shared two-way reports with Merv.  WH2XZO and WA3TTS also provided reports for Merv.    Consistency to and from KH6 is amazing.  DX report details can be viewed here.
