A few trans-Atlantic openings, many trans-Pacific openings and an absolutely miserable session of receiving from the south central US

– Posted in: 630 Meter Daily Reports, 630 Meters

This session can be summed up with two bullet points: 1) Propagation was pretty good, resulting in early reports, late reports, trans-Atlantic and trans-Pacific openings,  and 2) it was an absolutely awful night for trying to receive anything during the evening, overnight, and morning from here in the central US.  A particularly lightning-active storm system rolled across Oklahoma overnight and across portions of North Texas this morning.  While I never received any rain, noise was easily 30-over S9.  The only way the situation could have been worse would have been if I were under one of these storms.  I made the decision to sleep in, which was the right decision.   It didn’t matter what direction you were listening while using a directional receive antenna because there was probably a noisy storm in that direction.  The good news is bullet point 1:  Propagation was good if you were away from these storms and many active stations are, in fact, far enough way.

Geomagnetic conditions were generally quiet during this session but have begun to turn more active ahead of a forecast geomagnetic storm that should begin within the next 24-hours and potentially last 48-hours.  Hopefully this will bring with it a spark necessary for more great propagation while minimizing the elements that seem to negatively impact propagation.  It can happen because we have seen it recently.  The Bz was generally very near unity or pointing slightly to the North for much of the session but has since turned to the South.  Solar wind velocities were generally averaging near 300 km/s for much of the session but are currently averaging 360 km/s.  DST values were nominal, taking a characteristic dip in the last few hours:







WD2XSH/17 returned to receive duties during this session, providing reports for PA3ABK/2 and G8HUH for the first time in many months:

There may have been a number of trans-Atlantic reports “left on the table” due to pop-up thunderstorms in and around New England overnight.  John, WA3ETD / WG2XKA, reported that he had to cut his session short overnight due to storms that were not in the forecast.

The trans-Pacific path appears to have been nominal, although Larry, W7IUV / WH2XGP, reports that he had an amp failure due to a shorted power supply prior to the start of the evening portion of the session.  He is working to repair the damage and will hopefully be back to transmitting shortly, although he was successful providing reception reports overnight.  He is an important part of the team in that region, helping to identify openings, particularly on the paths to Asia and Oceania.

Ward, K7PO / WH2XXP, reports that he was decoded by 50 unique stations during the session, including a number of operators in VK:

Roger, VK4YB, categorized this session as a “code-5” and not really anything to get excited about.  He indicates that noise was low, however, but not many stations were being received on the long-haul path.  As a result he and Steve, VE7SL, opted to not try for another QSO during this session.  Roger was received once by WH2XGP.  He offered the following statistics:

Phil, VK3ELV, received a number of reports from JH3XCU late in the session yesterday after the reporting period closed.  Those reports are detailed below:

Neil, W0YSE/7  / WG2XSV, reports a big night on the path to KL7 that extended into the morning:



Rick, W7RNB / WI2XJQ, was “receive-only” during this session and provided the following statistics:

There were no reports from the trans-African path.  It was nice to have EK6RSC listening from Armenia during this session.  I do hope QRO stations in Europe will provide big signals for him to receive soon.

Eden, ZF1EJ, was limited to receiving stations in the southern US on both receivers during this session:

ZF1EJ/1 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, used this session for testing.  He began early with a transmitting test to verify his repairs to the Marconi-T that was damaged by wind while he was away in Europe.  He replaced the single top wire with three 25-meter wires following by a single 50-meter wire attached to the end of the triplet.  It seems he had a good night of being heard and confidence is high that once the noise drops a bit here he will be heard in Texas.  Laurence indicates that this repair has gathered him an additional 2-dB on ground wave and stands to improve as the trees lose their leaves.  The second test was to test decoders, specifically for KL7L and KL7L/2.  WE2XPQ was designated as WSPR 2.1 and the W1VD/AMRAD probe; KL7L was designated as the “ACESHIGH” probe and WSPR 2.12;  KL7L/2 was designated as “ACESHIGH” and WSJTx 1.7.0.  Both of the “ACESHIGH” probes were feeding the same R75 receiver.

Merv, K9FD/KH6 / WH2XCR, didn’t experience a repeat on the path to JA but had a solid night into VK, Alaska, and western portions of North America.  He also decoded three station with the fallen receive antenna:
