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

Unsettled geomagnetic conditions return as more strong storms plague the central US; VK -> JA openings are robust! Meager North and South openings continue to dominate North America

The details for May 20, 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.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

It was another stormy night in the central US and coupled with seemingly poor propagation and operators away at Dayton, activity was down.  Openings continue to favor more North / South paths which is more believable now that geomagnetic conditions are presenting at more active levels.  Noise was reported at moderate to high levels in Florida at WI2XBV while WA3TTS noted S5-S9 noise with higher lightning crashes. Mike noted that he only decoded VE3CIQ.  At least openings between Oceania and Asia have returned.  We will get through this shortly but its going to be a long summer.

11-hour North American lightning summary


Geomagnetic conditions reached unsettled levels for several reporting periods which is at least consistent with observed on air conditions for a change.  The Bz has been pointing to the South but has begun to recover and solar wind velocities are currently averaging above 700 km/s in the high category.  DST values have, not surprisingly, made significant decreases.




Phil, VE3CIQ, reported that he heard no stations but was heard by eleven WSPR stations with VE1HF representing his best DX at a distance 1200 km.

Joe, NU6O / WI2XBQ, indicated depressed conditions, receiving reports from thirteen WSPR stations with four stations at a distance of 1000 km.

Larry, W7IUV / WH2XGP, provided reports for two WSPR stations and he was reported by fourteen unique stations.  As W7IUV, Larry provided reports for two WSPR stations.  Larry indicates “Rather low noise last night but no signals! WSPRnet map indicates very low activity but still little or no prop here…been working on RX antennas and it’s hard to convince myself that something is not broke!”

Neil, W0YSE/7 / WG2XSV, reported that he was receive-only overnight with high noise.  He presented these statistics:

Dave, N4DB, reported a very slow night with only four total reports for the session, three of which were for VE3CIQ at a distance of 892 km.

Al, WD4AHB, reported, “I thought I was going to start out by saying, “It can’t get much worse than this,” but after looking at the overnight coverage map for US 630m I’m thinking I had a pretty good night of DX.”  Al provided one of two reports for ZF1EJ.  The other came from WH2XZO but was accidentally reported with 2200m data.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

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

Roger, VK4YB, reported “Those storms of yesterday have dissipated and QRN has been low all session. Domestic conditions have been good with +20dB S/N with VK2XGJ at 844 km for example.  Curiously there are only 15 active station within 10,000 km of my QTH since sunset and I have got a report from every one of them.”   Roger received reports from 7L1RLL4, JA1NQI, JA1NQI/2, JA3TVF, JE1JDL, and JH3XCU.

Regional and continental WSPR breakdowns follow:

North American 24-hour WSPR activity


European 24-hour WSPR activity


African 24-hour WSPR activity


Japanese 24-hour WSPR activity


Oceania 24-hour WSPR activity


Eden, ZF1EJ, received reports from two unique stations but as WH2XZO noted,  his ZF1EJ reports were accidentally included in the 2200-meter dataset so the map data only reflects reports from WD4AHB.

ZF1EJ 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, provided reports for only WH2XGP.  Night’s are getting very short in Alaska.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, was not reporting during this session due to a power outage.
