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

Nothing but unsettled geomagnetic conditions so far as propagation improves as the night progresses

– Posted in: 630 Meter Daily Reports, 630 Meters

The band was pretty good overnight but many stations reported that propagation and conditions were off their highs experienced earlier this week.  This is logical given the current active state of the geomagnetic field and numerous weather systems around North America that are generating snow and other sources of precipitation static.  Openings on a number of long-haul paths were numerous, nevertheless, and domestic propagation improved as the night progressed.  A few static crashes were observed this morning which may have originated in the Yucatan.

Geomagnetic conditions remained at unsettled levels for a number of reporting periods but at the time G1 storm conditions have not been observed.  The Bz is pointing to the North and solar wind velocities have been variable again, peaking near 700 km/s during this session and averaging 600 km/s.  DST values continue to behave erratically.







Michel, FR5ZX provided a number of reports to EA5DOM during this session.  Those report details can be viewed here.


EA5DOM, as reported by FR5ZX


The trans-Atlantic path between North America and Europe was favorable as WD2XSH/17, WE2XGR, and N1BUG all provided reports to EA5DOM and G8HUH.  VE2PEP provided reports to EA5DOM and VE9GJ, a new addition to 630-meters, reported DC0DX, EA5DOM, F1AFJ, and G8HUH.  John, WA3ETD / WG2XKA, was decoded by G0LUJ and G8HUH while providing reports to EA5DOM.  Report details for these stations can be viewed here.  John provided the following comments about the session and his trans-Atlantic reports:

“Conditions were off a bit here compared to the last week, with higher noise levels.  Consequently XKA was not hearing the PNW regulars.  However, EA5DOM was spotted once right at -30, and G0LUJ spotted XKA multiple times with a single report from G8HUH…TU all.”

Spiros, SV8CS, reported that the radio club on Faroe Island decoded his WSPR signal:

2016-12-08 18:12 SV8CS 0.475650 -22 0 KM07js 0.1 OY6FRA IP62oa 3290 334 

Its nice to see these guys on the air.  Another DXCC entity never hurts!

Neil, W0YSE/7 / WG2XSV, reports that due to winter weather, his system shut down due to high SWR around three AM local time but he reported these successes from earlier in the evening:

“WG2XSV Hearing 9:

Heard by 25:

I also decoded 2 JT9’s from Toby, VE7CNF.”

Rick, W7RNB / WI2XJQ,  reports a snowy night with a down receive session but his match stayed pretty stable, only needing to touch up a bit to find 50 ohms.  On the upside, Rick reports that the new IMAC is running WSJTx very well.  Rick provided reported for eight unique stations and was decoded by 27 unique stations.  His unique report details can be viewed here.

Larry, W7IUV / WH2XGP, received reports from 47 unique stations during this session including WE2XPQ, WH2XCR, and ZF1EJ.

Trans-Pacific report details from stations located on the North American mainland have been aggregated here.

Activity in Australia has been down recently which may be partly seasonal and partly due to poor weather conditions.   Roger, VK4YB, indicates that the storm system that brought down his antennas contained 310,000 strikes in his area alone, but storms from this session resulted in more than 1,000,000 lightning strikes.  Not many stations were QRV in northern and eastern Australia during this session.  In fact, John, VK2XGJ, provided this screen capture showing no VK stations reported at his station early in the evening:


Most VK’s are seeking refuge from the bad weather!

Ken, K5DNL / WG2XXM, reported that he received reports from 65 unique stations, including VK2XGJ and WE2XPQ.

Ward, K7PO / WH2XXP, received reports from 58 unique stations, including VK2XGJ and ZL2BCG.

Daytime activity at my station was interesting, with CW level reports a few hours after sunrise at WB0VAK and other stations in the northern US.  K5XL provided consistent WSPR reports through the day with a few reports by KU4XR through the afternoon.  Those report details from KU4XR can be viewed here. The post-sunrise report detail can be viewed here.  Reports improved as the evening progressed and I can only imagine that the band was stabilizing after several periods of unsettled conditions.  I had plans of operating both CW and JT9 during the evening session but as they say, “best laid plans…”  Overnight WSPR resulted in many very good domestic CW level reports.  Unfortunately this morning the variometer drive motor was frozen due to condensation in the housing so I did not transition to CW at 1120z as normal.  Fortunately the match was still good on WSPR so I could just continued my activity there.  I expect the motor will be thawed by noon.  My WSPR transmission reports for this session can be viewed here and my WSPR reception reports for this session can be viewed here.


WG2XIQ 24-hour WSPR activity


113 MF WSPR stations were observed at  0103z on the WSPRnet activity page.  VE9GJ provided a number of reports for what is believed to be the first time.  Welcome aboard!

Eden, ZF1EJ, provided reports for VE3EFF, VE7CNF, WD2XSH/15, WG2XIQ, WG2XKA, WG2XXM, WH2XGP, WH2XXP, and WI2XBV.  Report details for these stations can be viewed here.


ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, was only receiving through this session and reports very cold temperatures in KL7.  He successfully decoded WH2XCR and stations in the western US including WG2XXM in Oklahoma.


WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR,QRT’ed early for a morning sked on 160-meters but before doing so, he successfully reported JA1PKG and ZL2BCG.  Reports numbers were down from North America but still very good and the path to Japan yielded reports from JA1NQI-2 and JH3XCU and VK2XGJ and ZL2BCG in Oceania.  He also added that QRN was very high as storms persist in his area and likely will do so for a few more days.  Merv’s DX report details can be viewed here.


WH2XCR 24-hour WSPR activity

Merv and I have been discussing the recent polar openings and it seems that this path for him on 160-meters is actually over Central and South America on more of a skew path.  Stations in Europe are essentially listening to the South to hear his signal so it stands to reason that the same behavior is probably observed on 630-meters.  There is still so much we don’t understand about propagation but its very useful to be able to compare these openings to bands that have some relationship to 630-meters.  I am sure we stand to learn a lot more in the coming years.
