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

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Quiet geomagnetic conditions continue but so do noisy terrestrial storms; VK -> JA path returned and trans-Pacific path between North America and Oceania remains open; Great openings between KH6 and Oceania; Digital mode experimentation in western North America

The details for June 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.  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.

Noise conditions were more of the same in North America as big storms continue in the central US, Midwest, New England, parts of the Gulf coast and Mexico.   Based on a forecast I saw this morning, this pattern i

s expected to continue in some capacity into the coming overnight period.  WG2XKA in Vermont reports that it has been difficult to string together more than a day or two of operating before the next system arrives.

Geomagnetic conditions were very quiet through this session.  The Bz is pointing to the North and solar wind velocities are averaging near 345 km/s.  DST values continue to ride close to the centerline at positive levels.




Roger, VE7VV, and Neil, W0YSE/7 / WG2XSV, performed a number of digital mode experiments during this session.  Neil preliminarily reported that “Rod (Roger) VE7VV and I tried JT9 and JT65 last night starting around sunset (9PM, 0400z). Roger was running 10w TPO (~0.2w EIRP), and I was running my usual 100w (~1w ERP). I never saw any tracks or got any decodes from Rod, but he saw me in both modes”  Neil provided these additional comments and statistics from ON4KST chat reports and private emails.

Roger, VE7VV, reports that both his JT9 and JT65 (10W output, 0.2W EIRP) were decoded by VE7BDQ and W7IUV and that Larry’s decodings of him were Roger’s best DX using a non-WSPR mode, at 299 km.  Neil, WG2XSV’s, JT9 and JT65 were decoded by VE7BDQ, VE7VV, W7IUV.  Roger’s first decode of Neil (316km) was just after Roger’s sunset at -27 and the s/n improved to a peak of -12 about an hour later. There was considerable QSB.

Neil also indicated that on WSPR overnight he”decoded only XXP all night until SR when XCR came in with 4 decodes.”

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

Roger, VK4YB, reported that “QRN low, great domestic conditions with at least 20 VK/ZL stations active. Some all time S/N records tumble. WH2XCR was receiving at +7, beating the previous record by 3dB, and yet the shorter path to JA is barely there and that is despite hammering the JA beam for over 2 hours at the optimum time.”  Roger received reports from 7L1RLL4, JA3TVF, and TNUKJPM.  He provided reports for WH2XXP.

Larry, W7IUV / WH2XGP, indicates that he did not transmit last night, but he did provide reports for two WSPR stations.  As W7IUV, Larry provided reports for five WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 23 unique stations including ZL2AFP, ZL2BCG, VK4YB, and VK2XGJ.

Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for two WSPR stations and he received reports from three unique stations.

Laurence, KL7L / WE2XPQ, indicates that at his station, its “Not Nautical dark till around 9th Aug so wont expect much before then ; xcr on 475 and xnd on 137 made the dusky trip to AK”  He shared two-way reports for WH2XCR and he received report from VE7BDQ and W7IUV.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, shared two-way reports with VK3HP, VK4YB, VK5FQ, and WE2XPQ.  He received reports from VK2EIK, VK2XGJ, ZL2AFP and ZL2BCG.  Merv was reported by VK4YB well after local sunrise.   Merv’s DX report details can be viewed here.
