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

Trans-Atlantic path dries up but trans-Pacific path produces big results including first time reports for WH2XXP at JA1NQI-2; ZP4KFX listening during session; Noisy conditions in parts of North America

– Posted in: 630 Meter Daily Reports, 630 Meters

For those of us in the central and eastern areas of North America, this was a very noisy session.  Storms across the central plains and Midwest made listening impossible for stations that were East of the Rockies.  As with previous sessions, when one group of storms diminished another one intensified so this morning was not much of an improvement.  Fortunately propagation was good.

Geomagnetic conditions were very quiet with a North-pointing Bz and solar wind velocities averaging 300 km/s.







Its interesting that often when the trans-Atlantic path is active, the trans-Pacific path seems to diminished while reduced performance on the trans-Atlantic path results in an improved trans-Pacific path.  I’m speaking off-the-cuff with that observation but it seems to occur more often than not as I develop these reports each day.  It was certainly the case during this session.

Ward, K7PO / WH2XXP, had his best night ever, with reports from 48 unique stations including seven VK stations and first-time reports from JA1NQI-2 and VK2COW.  John, VK2XGJ, reported first decodes very early at 0814z:

Larry, W7IUV / WH2XGP, also reported a record night, with 12 WSPR stations decoded, including VK4YB.  He was decoded by 43 unique stations, six of which were VK’s in addition to ZF1EF.  Larry reports that he was listening with the omni receive antenna and only decoded WG2XKA on the transcontinental path.  He adds that the path to the East seemed down  compared to the previous session:

Steve, VE7SL, shared two-way WSPR reports with VK4YB during this session.  After yesterday’s excitement, both stations assessed that conditions were similar to yesterday before sunrise so they opted to remain on WSPR rather then trying for a repeat their historic QSO.  Steve notes that unlike yesterday, numerous sunrise enhancements were observed.  He adds, “It was a vy good E-W hr. Hrd 12 and hrd by 36 with several new calls reporting.”

John, VE7BDQ, operated both WSPR and JT9 during this session.  He decoded VK4YB as well:

Roger, VK4YB, reports the following statistics: “Spots 21*WH2XGP (-16) 44*WH2XXP (-12) 9*VE7SL (-24) 37*WH2XCR (-13) Decoded by WH2XGP VE7BDQ VE7SL WE2XPQ KL7L WH2XCR.”

Joe, NU6O / WI2XBQ, was trying to make it to VK4YB today at .5-watts ERP.  Roger reports a few faint traces of signal but no decodes resulted.  Joe, an avid AM BC band DXer, reported that “612Khz 4QR coming in +25, so there is hope… ”  He also indicated later that “JA AM BC stations were loud last night. 594, 747, 774 could hear program. I see there was a JA spot of XXP.”

Neil, W0YSE/7 / WG2XSV, reports almost no noise at all and very good signals from WE2XPQ.  He provided these comments and statistics:


Neil also provided a screen capture excerpt from evening JT9 activity:




Mike, WA3TTS, also reported high QRN levels but still managed to hear stations on the high latitude transcontinental path while listening in the opposite direction:

“John:  I used my NE EWE antenna overnight to minimize QRN from the midwest, although it did not help much until late.  Surprised to see 22 VE7SL decodes, best at -10:

2016-09-16 10:34  VE7SL  0.475633  -10  0  CN88iu  5  WA3TTS  EN90xn  3489  89

Also 36 decodes from WH2XGP, best at -11:

2016-09-16 09:32  WH2XGP  0.475688  -11  0  DN07dg  5  WA3TTS  EN90xn  3227  89

Too much QRN last night for any T/A chance…

Rick, W7RNB / WI2XJQ, submitted the following report from his receive-only session:


Regional and continental WSPR breakdowns follow:


North American 24-hour WSPR activity



South American 24-hour WSPR activity



European 24-hour WSPR activity



Japanese 24-hour WSPR activity



Australian 24-hour WSPR activity


There were no reports from the trans-Atlantic or trans-African path during this session.

Eden, ZF1EJ, operated two receive stations once again and the variations are interesting:

ZF1EJ/1 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, had another good session and apparently made some progress of repairing the damage from the previous night’s moose attack.  He reported VK3ELV very late and included a picture, shown below, of the sky during this same time frame.  One never knows:

Laurence reports that this is what the sky looked like while VK3ELV was being received in Alaska


Merv, K9FD/KH6 / WH2XCR, started early with -29 dB S/N reports from VK2XGJ at an amazing 0748z.  He was heard in the East by VE3CIQ and WG2XJM, in addition to a very robust collections of stations in VK including first time reports from VK2COW.  The West coast of North America and Alaska were also well represented.  Merv did a nice job decoding four stations using the 80-meter dipole that remains on the ground until a scheduled antenna party in November.  I’m a little surprised that JA1NQI-2 did not hear Merv during this session:

Jim, W5EST, present a very timely discussion, entitled, “POSSIBLE FUTURE 630M LONG PATHS”:

“With an historic first 630m JT9 QSO by VE7SL-VK4YB now documented, John WG2XIQ on yesterday’s reflector asked, ‘So now that this has been achieved, what’s next?’

The answer will be nothing less than the very deeds of the 630m community going forward!

Bringing QSO digimodes like JT9 and Opera into general and frequent 630m use on the various continents constitutes the very finest way to congratulate these two persistent and accomplished long path 630m operators.  And may they and others exercise the 630m transoceanic paths with increasingly confident reliability and deftly operated 630m radio receivers, transmitters, and antennas.

Today, in the ham spirit of possibility and opportunity, let’s  imagine some 630m long paths of the future.  E-mails and reflector posts from readers are the stimulation for today’s post, and thanks for them even if various ideas and mistakes are mine.  What would be some comparable 630m long paths?

I. Approximately same great circle distance except with:

  — entire great circle displaced in longitude   or

  –entire great circle flipped to opposite heading wrt north (Heading 2 = 360 degrees – Heading 1) or

  –entire great circle flipped as to hemisphere (Latitude 2 = – Latitude 1)

(Probably comparability is relative to magnetic poles rather than geographic N/S poles.)

II. In addition, the number of the ground reflections on comparable long paths would be similar and the number of salt water reflections on such long paths would be similar.

What’s the bottom line, taking considerations I and II into account?  What would be comparable 630m long paths compared to VE7/W7/W6 – VK/ZL that might even remotely become available? Across what other interesting paths may 630m QSOs come sooner or later?

Subject to country-permitted ham operation, consider these non-exhaustive path possibilities:

       northW6- CE/LU (Concepcion, Santiago/Buenos Aires, Bahia Blanca)


       W1/W4 – PY Brazil (Sao Paolo, Rio de Janeiro, Belo Horizonte)

       W1/VE1/VE2 – ZS (Capetown, Durban, Johannesburg) (all salt water)

       Europe-ZS/FR5 (Reunion Island)

       UK/EU – PY (Rio de Janeiro, Belo Horizonte)




       VK4/ZL – HK, HC, OA (Colombia, Ecuador, Peru)

       UA0-ZS (Novosibirsk, Krasnoyarsk, Ust-Ilimsk, etc) (mostly land)


       VU-VK6  (S. India, Hyderabad, Bangalore to Perth)

       A6-VK6  (UAE, Dubai-Perth)

       VK/ZL-BY (Shanghai, Beijing, many others)

Seasonal windows for some of these paths would be dictated partly by 630m propagation, extreme latitude the path may reach, and hemispheric seasons, and partly by overlapping dry/drier seasons. 630m propagation to, in and between the equatorial zones and other regions by 630m hams and experimenters is yet to be probed.

Whether you’re W/VE or DX, encourage your DX ham friends to experiment with 630m.  Testing 630m WSPR DX reception is the best way for anyone to start!”
