Propagation and QRN improves in North America; Several early reports and transcontinental openings observed; VI4SEA receiving JT9 and CW reports; Daylight savings time ends during the next session in the US

– Posted in: 630 Meter Daily Reports, 630 Meters

Propagation turned around for this session just as QRN decreased for much of North America through the evening and overnight.  A few stations were reporting pre-sunset signals on longer paths while others reported transcontinental openings.  This morning a small weather disturbance in my area brought light rain and a few rumbles of thunder but very little QRN was observed as a result:

Geomagnetic conditions are very different from the previous session.  Persistent periods of quiet have been observed through the session and the Bz has been pointing to the North for much of the night.  Solar wind velocities are low, averaging near 360 km/s.  DST values also suggest improved band conditions:

John, WA3ETD / WG2XKA, reports early openings to the Caribbean plus transcontinental decodes.  He provided these comments:

“A somewhat better, but very average session here.  A week of scattered showers and wind improved ground conditions at the expense of soaking nearby foliage.  The east was well represented, and several PNW stations reappeared.  VE7SL reported and was heard for the evenings best DX.  Considering the date, hopefully late fall conditions will improve.”

Mike, WA3TTS, reported WH2XGP early on the transcontinental path in addition to a number of other stations in the West.  Mike submitted the following comments and highlights:

My NW EWE antenna was the low noise alternative again last night.  Still noisy to the NE and SE here so no attempts at T/As…

I noticed my feedline loop resistance was varying last evening by a few ohms and had to apply DC sealing current 3 or 4 times for it to settle down. Must be time to clean and oil all the ground and F-connector conductor surfaces….seems like it only takes an ohm or so of feedline loop resistance for the low level intermod to creep into the rx antenna and feedline system (especially with a handfull of 10KW to 50KW AMBC stations nearby) …..then I start seeing an increase in false decodes under strong WSPR2 signal handling situations.    73 Mike wa3tts”

 

Ward, K7PO / WH2XXP, was reported by VI4SEA, VK2XGJ, and ZL2BCG during this session.  Those trans-Pacific reports can be viewed here.

Ron, NI7J / WH2XND was reported by VI4SEA:

wh2xnd-110516

WH2XND, as reported by VI4SEA

 

Larry, W7IUV / WH2XGP, reports that he decoded WE2XPQ on  2200-meters but not 630-meters.  Similarly Larry reports that 160-meters was pretty dead.  He adds that 630-meters was better than he has observed in several days.  He decoded fifteen WSPR stations using the omni receive antenna and he was decoded by 45 unique stations.  He also shared two-way reports with VI4SEA and received a report from ZL2BCG.  Those trans-Pacific reports can be viewed here.

Doug, K4LY / WH2XZO, saw a return of high latitude openings and provided these comments and statistics:

“With the week long disturbed conditions ending, the VE7./South Carolina path returned .  However, the more southern latitude path, Hawaii/South Carolina  of the past week disappeared!  What might explain that?  The 10 unique stations decoded and the 32 who decoded XZO is the most in a week.”

We have had a number of low latitude auroral warnings posted in the ON4KST chat over the past week which may explain why the southerly path to the West has been less robust over the past week.

Rick, W7RNB / WI2XJQ, reports that he decoded eight WSPR stations and was decoded by 25 unique stations.  He offered these comments:

“It seems things have improved a bit since last session. More stations reporting and even a new one for me KC7I in Hawaii, on vacation. I was glad to see some of the mid-west stations returning too.  I’m just a bit surprised that the spots don’t seem to be reciprical . Maybe that will return soon”

There seems to be a lot of the “diode effect” recently and it may be more complicated than just noise impacting S/N.  Rick’s unique reports can be viewed here.

Mal, G3KEV, reported MF Hellschreiber activity in Europe on the RSGB-LF reflector with received signals from IW4DXW.  No screen capture was provided.

VI4SEA received WSPR reports from VA7BBG, VE6JY, VE7BDQ, and VE7SL in addition to other reports detailed within this report.  Those four station’s report details can be viewed here.

VI4SEA also received several reports on the VK/ZL 600m Yahoo group.  Ron, VK3AFW, reported:

“Better tonight.  CW 539…JT9, -7, -8, missed some decodes due to fiddling here.  WSPR2 initial tx seemed off frequency.  Decoded at -4, 4.”

Andrew, VK5CV, reports that he has decoded VI4SEA on JT9 for the previous two sessions but work obligations have prevented him for making a QSO.  He adds:

“Stronger earlier but about -25 that time.  I am transmitting in the odd mins.  See that you are back on WSPR now.”

 

Steph, VK5FQ, captured the CQ of VI4SEA in addition to VK5CV calling him:

I skipped the evening CW session due to a headache and perceived poor conditions due to the previous session.  Propagation was probably ok and noise was low.  This morning pop-up storms forced me to cancel the morning session.  Right now my plan is to be QRV for CW at sunset tonight but that is subject to change and tomorrow morning marks the end of daylight savings time so, weather permitting, I will be QRV but after 1100z rather than 1000z.  It may take a few days to adjust the start times of my CW activity in order to be active around sunrise and sunset.

WSPR activity produced early results at WG2XKA and Larry, W7IUV / WH2XGP, reported that I was being decoded one-half hour prior to local sunset.  At 0326z, VA7BBG reported my signal in North British Columbia at -27 dB S/N.  He adds that coastal thunderstorms were complicating listening.  My WSPR transmission reports can be found here and my WSPR reception reports can be found here.

Laurence, KL7L / WE2XPQ, experienced improvements as the geomagnetic conditions stabilized but he reports that he is not hearing European HF stations on the polar path yet which is often a prerequisite for quality openings to develop.  He received late reports from VE7SL in British Columbia, who was in full sun.  Additionally, he was able to decode VI4SEA as well as two-way reports with WH2XCR.  Those reports can be viewed here.

Merv, K9FD/KH6 / WH2XCR, continues to receive numerous reports from the eastern portions of the US and as sunrise approaches, western stations appear to be hearing Merv well.  Both the JA and VK paths appear to be less robust than the previous session although lightning-rich storms systems are active between Hawaii and both destinations this morning.  Reports from VK2XGJ came only shortly before sunrise in KH6.  Merv’s JA and VK reports can be viewed here.
