Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Worst session in quite some time and the geomagnetic field has not reached storm levels yet!; VK -> JA path minimally open but openings to North America are closed; Solid openings between KH6 and VK

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.

What a difference a year (and a day) makes!  This session was characterized by high noise from a major storm system in the central US.  But in spite of elevated noise, which we have been dealing with for a while, propagation, even short-haul domestic openings, was really tough.

11-hour North American lightning summary


Geomagnetic conditions reached unsettled levels as a geoeffective coronal hole is firmly in position to effect Earth.  Storm levels have not yet been observed but G1 or G2 storms are possible.  The Bz is pointing to the South and solar wind velocities are averaging near 565 km/s.  Proton levels have returned to normal.  DST values have decreased but don’t look as poor as on air conditions suggest.




Phil, VE3CIQ, reported that he decoded two WSPR stations and he was decoded by twelve unique stations, all within 1200 km.

Larry, W7IUV / WH2XGP, reported poor conditions compared to last winter.  He provided reports for four WSPR stations and he was reported by 22 unique stations.  Larry also references lower activity but notes that band conditions seem worse than what we normally observe for May.

Rick, W7RNB / WI2XJQ, provided reports for seven WSPR stations and he was reported by fifteen unique stations.  Rick’s unique report details can be viewed here.

Neil, W0YSE/7 / WG2XSV, provided the following comments and statistics from the Vancouver, Washington area:

Al, WD4AHB, reported, “I used my wire/LPF combination again and spotted the usual suspects J and what looks like a garbled sequence from M74LOV. I observed very low noise levels over the monitoring period and hopefully others saw some good DX.”  He provided the following statistics:

Trans-Pacific openings were very limited during this session.  Report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, provided a link detailing VK -> total JA DX  and VK -> JA peak S/N for the session.

Roger, VK4YB, reported, “No long haul DX as expected for this time of the year. Low noise and good shorter paths yield S/N of +12 dB at 2664 km (ZL2AFP) and 0dB at 7597 km (WH2XCR) but in Japan, best was -27 dB at 7058 km (JA3TVF). Note the Japan path is almost 30 dB worse than Hawaii.”

I thought this was an awful session.  I started WSPR close to sunset and opted out of any CW due to other commitments.  I actually thought about operating CW early this morning but a check of band conditions around 0920z suggested that it was probably best to go back to bed.  My transmission report details can be viewed here and my reception report details can be viewed here.  Both data sets are as weak as I have seen them in a long time.  That is just the reality that is presented this time of year.

Eden, ZF1EJ, provided reports for three WSPR stations and he received reports from nine unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, indicated that he didn’t turn on the preamp last night so all of his reports were outbound and limited to western North America and Hawaii.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR,provided reports for WE2XPQ, ZF1EJ, VK3HP and he shared two-way reports with VK4YB.  He received reports for VK2XGJ and ZL2AFP.  Openings to Oceania look pretty good but may be down just a bit from the previous session.  DX report details can be viewed here.
