Current Operating Frequency and Mode

OFF AIR - but back tonight after dark for more CW

Relatively good domestic session with improved activity; A few more trans-Pacific openings and reasonable path between VK and JA

The details for May 14, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.

There were three primary weather related noise sources during this session:  one located in the north central region of the US, eastern Mexico, and off the gulf coast, into the mid-Atlantic region.  Activity in the Northeast and mid-Atlantic region northward was low so I can only imagine that noise levels were very high.  Domestic propagation was good once again, bringing out a few more operators that have recently been in dry dock due to local weather conditions.

11-hour North American lightning summary

 

Geomagnetic conditions remain quiet but at elevated levels ahead of a forecast geoeffective coronal hole.  The Bz has been pointing to the North, in many cases quite strongly, and protons have been elevated through a number of periods overnight but are have returned to normal levels this morning.  Solar wind velocities are averaging near 345 km/s and DST values are showing signs of a peak which may be the peak often observed before a dramatic decrease occurs.  We should know by tomorrow’s report whether the coronal hole is in position or DST is flirting with us.

 

 

 

Al, K2BLA / WI2XBV, reported big QRN this morning due to storms on either side of Florida.  He decoded six WSPR stations and was decoded by fifteen unique stations.  Al submitted these comments, indicating that his transmitting is coming to an end for the Summer months:

“My ‘seasonal’ radials are up and draped over my pasture fences ready to be wound on large reels. Transmitting is over until the radials are put back down in the Fall. I may still receive on my loop or my vertical without much in the way of impedance matching but my summer work schedule is rather hectic, starting tomorrow.”

Rick, W7RNB / WI2XJQ, provided reports for seven WSPR stations and he received reports from 21 unique stations.  Rick’s unique report details can be viewed here.

Ernie, KC4SIT / WI2XQU, indicates that he received reports from twenty unique stations, all of which were at or East of Texas and Oklahoma.  He provided the following statistics:

Neil, W0YSE/7 / WG2XSV, reported increased activity in his region as he filed this report:

Dave, N4DB, reported that he decoded nine WSPR stations, none of which were over 3000 km distant, with low QRN.

Al, WD2AHB, reported, “No more troubles with malware muting my VAC so I had a uninterrupted session of receiving spots. I racked up 8 unique spots over the monitoring period of ~0130 to 1000 UTC. QRN from lightning was not much of a problem.”

Mike, WA3TTS, reported, “12 stations decoded overnight. I started with SE EWE antenna to pickup WH2XXC before sunset, then NE EWE until about 0200, then NW EWE antenna overnight…results overview by distance and best SNR…”

Mike closed, commenting that he “…ran a split LF/MF converter IF overnight also monitoring WH2XND on 2200m (69 spots best -17).  I was surprised not to hear ZF1EJ overnight, but I did not use the SE EWE antenna in this session with the QRN off the Atlantic coast. VE1HF has been active and so far no recent decodes here. Nice to see VE7BDQ make it into EN90.  Congrats to K8PZ on the 630m transverter win.”

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, indicated that he received , “3 spots from the lower 48, but a swag from Laurence, WE2XPQ. The Japan path was also open. Moderate QRN restricted receiving.”  Roger received reports from JA1NQI, JA3TVF, JR1IZM, W7IUV, WD2XSH/20, WE2XPQ, and WH2XCR.

Steph, VK5FQ, received reports from JA1NQI.

Ken, K5DNL / WG2XXM, indicates that he decoded seven WSPR stations and he was decoded by 46 unique stations including ZL2AFP, WH2XCR, ZF1EJ, and seven Canadian stations.

Larry, W7IUV / WH2XGP, indicates that his system remained on the air all night so perhaps his recent problems are solved.  He also added that “RX conditions relatively poor, just not hearing well on any band.  TX conditions somewhat better but still not great.  Been plagued with high noise levels here, so my normally good RX reports are suffering badly.”  Larry provided reports for eight WSPR stations and he received reports from thirty unique stations including ZL2AFP.  As W7UIV, Larry provided reports for nine WSPR stations including VK4YB.

David, N1DAY / WI2XUF, sent this note about his recent receive receive antenna work:

“One opportunity that 630M has given me that I really enjoy is making and testing of loop antennas for receiving signals.  Yesterday, I finished construction of a dimensionally scaled down receive loop antenna which is 4′ in diameter and contains 32 turns of wire connected to a 360pf variable capacitor with a feed loop that goes slightly less than the circumference of the loop.  I had 11 spots with the antenna last night and it seems that the antenna is performing as well as the bigger 6 foot diameter 16 turn antenna that I previously built.  Although more testing is needed, one thing I noticed with the smaller antenna last night is increased ability to tune various stations in and out.  Ernie – WI2XQU lives 8 miles northeast of my QTH, while Doug, – WH2XZO is 30 miles southeast of my location.

Needless to say, given their proximity, both have very strong signals at my QTH, and their relative geographic location gave a good opportunity to test the antenna because when it is aimed at either of their locations, the other one is in the antenna’s null zone.  When aimed at Ernie’s QTH, I could peak his signal at +20 dBm while dropping Doug to -14 dBm.  Turned the other way toward Doug’s qth, I could peak his signal at -2 dBm while attenuating Ernie’s signal to 0 dBm.  On more distant signals, I was able to tune in, or totally obliterate several signals that were hundreds of miles  to the North and West of my qth by rotating the antenna in and out of the null area.
So far, I am not certain if the loops are going to provide me any improved reception over my go-to listening antenna which is an inverted L that goes vertical 70 feet then horizontal 70 feet.  Reception on that antenna has been quite good but I will continue to experiment.  Attached is a picture of the 32 turn L’il Miss Marconi.  Maybe it is time to take an extended QRT because I am not sure if giving antennas names is too healthy  Hi Hi.”

This session began for me with a bit of CW at sunset and into darkness.  QRN levels were low enough and there were only slight lightning crashes very low in the noise floor.  There were no phantom calling stations during this session that I observed either.  WSPR activity subsequently began later and yielded reports from the first transmission into the upper Midwest and points East.  The band continued to sound like it was in good shape in spite of later openings in the West as sunset continues to arrive later in the Pacific Northwest.  My transmission report details can be viewed here and it was a good night of domestic openings as I continue near 3-watts ERP (5-watts EIRP) and 17% duty cycle.  My reception reports were also improved a bit and are on par with what I observed a year ago.  Those report details can be viewed here.
