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.

The MF Solutions transmit converter giveaway is over and WE HAVE A WINNER!  John, WA3ETD / WG2XKA, provides the results:

“The following 630m enthusiasts entered to win the TX converter.

K8PZ    Steve
K1UTI   Bob
KU4XR Andy
N6SKM  Steve
WD4AHB Al

My wife drew Steve, K8PZ from the cap.  The kit will be mailed Monday after determining the desired LO crystal.  THANKS to those that entered, and I’m sure we’ll see all you guys on the band!

Congratulations Steve  (K8PZ) !

This session was quite varied.  Some areas experienced great band openings on domestic paths while others struggled to hear more than a couple of stations.  I am certain that noise was the major player for operators in the Southeast and, in fact, many operators played a game of “cat and mouse” with storms through the evening and  overnight.  It was relatively quiet in the central US compared to the previous session.  Parts of the Northwest, southern Alberta, Canada and Big Sky country, however, continue to experience noise-generating storms.

Geomagnetic conditions continue at quiet levels.  The Bz is currently neutral and solar wind velocity has dropped below 300 km/s, averaging near 295 km/s.  DST levels continue at positive values and are currently cycling upward.  Solarham reports that the next coronal hole to be geoeffective will be in place after May 15.

 

 

 

Al, K2BLA / WI2XBV, reported moderate noise this morning where he operated for only one hour at half his normal power levels.  Al decoded six WSPR stations and he was decoded by 21 unique stations including VE6 and VE7.

Ken, K5DNL / WG2XXM, provided reports for eight WSPR stations and he was reported by 43 unique stations including WE2XPQ, WH2XCR, ZF1EJ and seven Canadian stations.

Doug, K4LY / WH2XZO, reported that he was at “ground zero” for strong storms that allowed activity for only half of the session.  He reported nine WSPR stations and he was reported by 26 unique stations including VE6 for his best session DX.

Neil, W0YSE/7 / WG2XSV, noted that he has a “dopplegänger”.  He explains:

Dave, N4DB, reported strong storms in Virginia once again that is finally coming to an end.  He reported eleven WSPR stations but noted once again that he had no stations over 3000km in distance.   Eden, ZF1EJ, at a distance of 2024km, was his best DX for the session.

Ernie, KC4SIT / WI2XQU, reported, “WI2XQU was QRT for a couple of hours this last session due to lightning storm. I had 21 unique stations spot me but I worked no further west than east Texas/Oklahoma. Here’s the map and database:”

Al, WD4AHB, reported, “During a mid-session check on my received spots I discovered that my computer had been muting recording devices causing WSJT-X to lose signal and fail to decode anything. It appears to have been some malware surreptitiously hiding amongst the ones and zeros. Multiple scans/reboots with Malwarebytes and Windows Defender seems to have removed it. But, even with a large time gap between spots I racked up 8 including our mysterious traveler, M74LOV.”  Al provided the following statistics:

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

Roger, VK4YB, reported “No NA spots in either direction tonight. I think this will be the norm until mid August. Lots of VK/ZL activity, with at least 15 stations active.”  Roger also noted a report from JA1PKG at +9 dB S/N but it seems likely that this was an exercise in variable filter bandwidth.  Other reports, like those from JA3TVF at -18 dB S/N are more in line with what is normally observed.  Roger received reports from 7L1RLL4, JA1NQI, JA1PKG, JA3TVF, JR1IZM, and TNUKJPM.  Roger shared two-way reports with WH2XCR.

I started the session with a bit of pre-sunset system testing running QRO CW on 474.5 kHz.  I called CQ for about an hour at 1 minute intervals and noted one station attempting to get my attention.  No call sign was ever given but it was definitely an intelligent signal and not a broadcast birdie.  I also believe that this station was different from what I have historically referred to as the “phantom ditter”.  I do suspect it was someone testing a transmitter, however, and within ground wave range of 200-300 miles.  The band sounded very nice in spite of storms far to the East.  I transitioned to WSPR at 0030z, receiving early reports from WG2XXM.  I continue to operate “barefoot” at about 45-watts TPO (about 3-watts ERP or 5-watts EIRP) and 17% duty cycle.  The long days mean that sky wave openings are slow to develop but openings around North America were quite good in spite of elevated noise after dark.  The band continued to improve through the overnight and my transmit numbers looked pretty good.  Those report details can be viewed here.  My reception numbers were also improved although down for such a lot transmit duty cycle.  Those report details can be viewed here.  I may use the directional antennas instead of listening omni in the coming days for comparison.

Laurence, KL7L / WE2XPQ, continues to experience similar openings for the past few session.  He shared two-way reports with WH2XCR and provided reports for stations in the West as well as WG2XXM in Oklahoma.

WE2XPQ 24-hour WSPR activity

 

Merv, K9FD/KH6 / WH2XCR, continues to do well on the path to Oceania.  He provided reports for VK3HP and VK5FQ and he shared two-way reports with VK4YB.  He received reports from VK2XGJ, ZL2AFP, ZL1BPU, and VK7TW.  To the North and East, Merv also reported ZF1EJ and shared two-way reports with WE2XPQ.  Merv’s DX report details can be viewed here.
