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.

Its been a while since I have been able to report a good session. While there was some elevated noise during the evening, many stations took advantage of quieter conditions overnight. This was probably the strongest session in over a month with lower noise by morning and strong openings both on short and long haul paths. Noise levels were low enough and propagation was good enough that the noise floor “bump” located in the vicinity of 475.630 kHz – 475.640 kHz was visible by several stations. Typically this is a Winter feature.
Geomagnetic conditions have returned to quiet levels. The Bz is riding the center line this morning and solar wind velocities are now averaging 370 km/s with a few excursions above 400 km/s but velocities are generally at low levels. DST values are also riding the center line again, favoring slightly negative values for much of the session.
Phil, VE3CIQ, reported active evening storms but that didn’t prevent him from reporting WG2XXM, WH2XGP, WH2XXP, WH2XZO, and WI2XSV.
Larry, W7IUV / WH2XGP, provided reports for nine WSPR stations and he received reports from 24 unique stations. Larry indicates that his western receive system, reporting as W7IUV, is currently off line. His WH2XGP receiver is now using a tuned loop oriented East and West.
Neil, W0YSE/7 / WG2XSV, reported “Similar results to previous session except that Mark, KU7Z near my old QTH in Utah, joined the mix.” Neil decoded VE7BDQ, WG2XXM, WH2XGP, and WH2XXP. He was reported by KU7Z, N6RY, N6SKM, VE6JY, VE6XH, VE7AB, VE7BDQ, W6SFH, WH2XCR, WH2XGP, WI2XJQ, and WW6D.” Neil adds “…And now the days start becoming shorter after this…” Shorter days can’t happen fast enough in my opinion!
Doug, K4LY / WH2XZO, reported “Better conditions and a little less QRN resulted in decoding 8 stations including WH2XGP for the first time in a few days and being heard by 15 stations including two VE6’s. I discovered that my receive frequency had been off by 0.100 kHz the night before last- the reason I had no decodes!”
Mike, WA3TTS, reported that he decoded ten WSPR stations, including two decodes for VE7BDQ for the first time in at least a month while listening with the Northwest EWE antenna. Mike noted that he decoded WH2XGP nine times. He added that he was able to visually identify the anomalous signals between 475.630 to 475.640 kHz from 0300z to 0600z. Mike provided the following map detailing his reports:

Hideo, JH3XCU, provided this link detailing VK -> total JA DX and VK -> JA peak S/N for the session.
Roger, VK4YB, received reports from 7L1RLL4, JA1NQI/2, JA1PKG, JA3TVF, JA8SCD5, TNUKJPM and JH3XCU. He shared two-way reports with WH2XCR and he provided reports for WH2XXP and WG2XXM. Roger provided the following comments for the session from his perspective:
“The Mackerel Sky has rotated slightly clockwise cutting off the path to the Pacific North West and opening the path to Ken, WG2XXM, in Oklahoma. At sunrise in the Caymans, I switched to the original Bottom Hat hoping to get a spot from Eden, ZF1EJ, but no such luck. Ward, WH2XXP, was strong throughout. His last decode was at 12:36, but a trace was still visible at 12:42 and 12:48, well past his sunrise of 12:18. The path to Japan from Brisbane does not normally follow a corridor through the Mackerel Sky, as it does to Hawaii. Rather it has to bump its way through on every hop. The path to Hawaii, although longer, is usually at least 20dB better than to Japan. Some of that advantage would be owing to the very low noise receiving set-up of Merv, WH2XCR. I am trying to make sense of the data and this is my best guess so far. I dare say it will change with more study. I now have 6 full size antennas to help. There are three 900 ft long wires pointing to the North-East, North-North-West, and South-West. There are two, near identical, Bottom Hat verticals. One favours the East, the other favours the West. I don’t know why this is. The last antenna is a conventional base loaded vertical with a small top hat.”
Ken, K5DNL / WG2XXM, reported a much improved band and he provided reports for seven WSPR stations. He received reports from 29 unique stations including VK4YB, WH2XCR, ZF1EJ and eight Canadian stations.
Ward, K7PO / WH2XXP, received reports from 32 unique stations including VK4YB and VK2XGJ.
It was obvious from the start that this was going to be a good session. Noise was a bit more elevated as I began the session around 0230z but I received reports from six stations on my first transmissions. JT9 and CW levels were observed through the night and I can only hope that propagation and band conditions are at least this good for this weekend’s MF and LF activtiy during Field day. I shared two-way reports with WH2XCR, which has not occurred in some time. My transmission report details can be viewed here and my reception report details can be viewed here.
Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, reported that he was “receive only” overnight as high winds on Cayman meant that he needed to lower the tower which supports the transmit antenna. He operated two-receivers / antennas overnight and as ZF1EJ he provided reports for five WSPR stations. As ZF1EJ/1 he also provided reports for five stations. He indicated this afternoon that the configuration was ” ZF1EJ Inlogis RF PRO-1B Receive Loop, ZF1EJ/1 160m Inverted V.”
Laurence, KL7L / WE2XPQ, provided reports for three WSPR stations and he received reports from four unique stations. He shared two-way reports with WH2XCR.
Merv, K9FD/KH6 / WH2XCR, provided reports for VK3HP and VK5FQ and he shared two-way reports with WE2XPQ and VK4YB. He received reports for VK2XGJ. Merv’s DX report details can be viewed here.
