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.

Noise conditions improved for the session where, by morning, North America was generally storm-free, aside from the Florida and portions of the eastern gulf coast region. I detected little noise from these storms this morning but operating late and after sunrise in the Southeast meant that those storms were in full sun and struggling to propagate their noise very far.
Geomagnetic conditions were quiet and very similar to the previous session. The Bz is pointing to the North and solar wind velocities are averaging near 350 km/s. DST values have continued generally on the positive side of the centerline.
Joe, K9MRI / WI2XUL, was calling CQ on 475 kHz CW during the later evening and the activity was captured by Mike, WA3TTS:
Andrew, VK5CV, and Dale, VK1DSH, have recently been working to complete a digital mode QSO but so far noise levels have made the process very difficult. Andrew indicates that Dale was 100% copy at the start using Thor4 but conditions deteriorated. They have recently tried JT65 and will transition to JT9 and / or Hellschreiber plus a few other modes that can be found in the FLDigi suite. Both stations will continue their QSO pursuit this weekend.
Edgar, EJTSWL, located in Tasmania, posted this waterfall capture of the QSO attempt. Apparently his copy of Dale was pretty good:
Steve, K8PZ, reported a “Relatively quiet night here with S3 – S5 noise. ZF1EJ made a brief appearance after a long absence, the balance are the usual suspects in my decode file. Overall a good listening night.”
Neil, W0YSE/7 / WG2XSV, reported “Low noise this session for me. Results similar to previous session. WG2XSV Heard only these 3: WH2XGP, WH2XXP, WI2XBQ Heard by 8: NK7Z, VE6XH, VE7VV, W7IUV, WH2XCR, WH2XGP, WI2XBQ, WI2XJQ”
Ernie, KC4SIT / WI2XQU, reported that the Northwest continues to be absent from his reports. He provided reports for nine WSPR stations and he was reported by seventeen unique stations.
Ward, K7PO / WH2XXP, received reports from 31 unique stations.
Larry, W7IUV / WH2XGP, provided reports for four WSPR stations and he received reports from twenty unique stations. As W7IUV, Larry provided reports for six WSPR stations.
Mike, WA3TTS, reported that last night was “…Noticeably quieter than previous night. Good contrast on 630~638 racing stripe in waterfall around 0400 utc. Copied WI2XUL on CW 475.080 last night around 0230 in tight 100Hz audio and 300Hz Collins mechanical filter, WSPR2 sigs from XUL were -16 just several minutes prior to this video (posted earlier). I was on the SW EWE antenna until about 0500 then NW overnight until past SR.” Mike provided the following statistics:

Hideo, JH3XCU, provided this link detailing VK -> total JA DX and VK -> JA peak S/N for the session.
Roger, VK4YB, reported “…Heavy QRN here tonight but storms are all out to sea, A path to WH2XXP may have existed but the static gave us no chance to hear him. Even WH2XCR was difficult to decode, especially earlier. The JA path was a little better than yesterday.” Roger received reports from JA1NQI/2 and JA3TVF. He shared two-way reports with WH2XCR.
The band was quiet during the evening (pre-sunset), affording me the opportunity to look for an early CW QSO and gather a bit of ground wave data. The band was quiet into the sunset period but I transitioned to WSPR at 0130z for the night. I miss Winter darkness. Its tough to stay up late and wait for the good band conditions to manifest which typically begin late in the evening during the Summer. WSPR activity was slow to manifest but after full darkness a few stations reported me. The band seems to have been in pretty good shape, primarily with JT9 levels reported although CW levels are probably also present. With my recent change in power level between digital modes and CW, its more challenging to make a direct comparison. For my 17% duty cycle, however, my transmit and receive numbers look good for this time of year. I am operating CW this morning again through the sunrise period and looking for a QSO. The sun is up earlier each day.
Also I noticed that my 472-grabber was dead or lacking in performance since last weeks strong storms. I traveled to the remote site and took the probe down and found the board to be crispy. Looks like a nearby lightning strike popped it (it also doesn’t help that this remote receiver is located about one mile away and takes a beating from my transmissions). The entire probe is replaced now and the signal quality seems significantly better so the failed unit may have been decreasing in performance over the last few years that it has been in the air. I’ve made some notes about where the new probe is starting out so I can address problems more quickly next time.
The regional and continental maps were a mess for this session after a VA2 station injected many bad reports into the MF dataset due to poor band selection procedures. I am excluding the North American and European maps for this session because the visual representation is not even close to accurate. Please be careful with your band selections.
Eden, ZF1EJ, provided reports for one WSPR stations and he received reports from ten unique stations.
Laurence, KL7L / WE2XPQ, provided reports for three WSPR stations and received reports from two unique stations. Laurence shared two-way reports with WH2XCR.
Merv, K9FD/KH6 / WH2XCR, provided reports for VK3HP and shared two-way reports with VK4YB and WE2XPQ. Merv received reports from VK2XGJ. DX report details can be viewed here.
