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

Current Operating Frequency and Mode

OFF AIR but returning after dark on Saturday night

More strong storms in Central and Midwestern US creating problems for operators in the eastern half of North America; Situation only moderately better in the West where trans-Pacific paths struggle to hang on; MF Solution transmit downconverter drawing and giveaway registration period is open!

The details for April 30, 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.

This session was another night with a “skeleton crew” on duty as the eastern half of the US was rocked by big storms and big noise.  Its once again impossible to accurately comment on propagation with limited active operators but based on West coast reports where the QRN situation may have been marginally better, propagation appears to have been poor for longer haul paths and marginal for domestic openings.  The path to Australia to North America  may have improved to a slight degree.

12-hour North American lightning summary


Geomagnetic conditions continue at quiet levels. The Bz has been pointing to the North although in the last few measurement cycles this morning it has turned slightly to the South.  I don’t believe there is anything new expected and think the reports will return to the North shortly.  The solar wind velocity is averaging near 370 km/s.  DST values are either near the center line or have pushed into positive territory.  Referencing a recent article that was linked in a recent blog post, it is theorized that after major geomagnetic events as experienced last week, electrons can be severely depleted to the point where propagation may be severely impacted.  Whether that is what we are observing is unknown but it certainly fits the profile.




Mal, G3KEV, reported that he was looking for CW QSO’s on 472.5 kHz during the evening.  No reports were provided indicating whether any QSO’s were completed, however.

As reported yesterday, John, WA3ETD / WG2XKA, of MF Solutions is going to hold a drawing and giveaway for one of his 630-meter transmit downconverters.  Details and rules for submitting your name for consideration can be viewed here.

Neil, W0YSE/7 / WG2XSV, reported a decent session at very low power levels from Vancouver, Washington.  Neil provided these comments and statistics:

Phil, VE3CIQ, reported a tough session, indicating that he decoded one WSPR station while receiving reports from five unique stations with the furthest station at a distance of 500 miles.  Phil also noted that as his region has doubled it’s rainfall for April, the trees are full of RF absorbing leaves.

Dave, N4DB, reported that he decoded four WSPR stations including WH2XXP at distance of 3100 km and ZF1EJ at a distance of  2024 km.

Ken, SWL/EN61 (SWL/K9), located in Indiana reported that he provided three reports for WH2XGP overnight while using an indoor ferrite loop-stick antenna due to excessive lightning.

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, reports, “QRN low to moderate. Propagation has improved somewhat. Now getting some reports from NA, and even one from Japan.”  He received reports from JA3TVF, W7IUV, WE2XPQ, WH2XCR, and WI2XBQ.  He provided reports for WH2XCR, WH2XXP and WH2XGP.

Ward, K7PO / WH2XXP, received reports from 43 uniques stations between 0518z and 1218z including VK4YB, VK2XGJ, EJTSWL, and ZL2AFP.  He notes that his reports from VK were down with only eleven decodes during this operating period.  The path to ZL was considerably better, however.

Larry, W7IUV / WH2XGP, provided reports for three WSPR stations and he was reported by 24 unique stations including VK4YB and ZL2AFP.  As W7IUV, Larry provided reports for six unique stations including VK4YB.  Larry notes that propagation was poor to the East and that trans-Pacific paths are barely existent.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity



South American 24-hour WSPR activity


European 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for two WSPR stations and received reports from two unique stations.  It was a tough night for the Caribbean.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, experienced a slightly better session on paper with the return of reports for VK4YB.  He also shared two-way reports with WH2XCR, while reports continue to be concentrated in the western portions of North America.  The season is progressing at high latitudes where full darkness periods will begin to decrease at a dramatic rate.  DX report details can be viewed here.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, reported extremely high QRN and rain  noise due to his own storms on and near the island.  Even so he provided reports for VK3HP and shared two-way reports with VK4YB and WE2XPQ.  He received reports from EJTSWL, ZL2AFP, and John, VK2XGJ, who noted another night of early reports, providing Merv with a -26 dB S/N report at 0754z. Coverage in  North America was, not surprisingly, limited to the western region.  DX report details can be viewed here.

WH2XCR 24-hour WSPR activity
