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

Current Operating Frequency and Mode

Probably QRT tonight and in the morning due to storms in the area

Noisy night but good propagation, particularly on long haul Pacific paths; Return of JA openings for WH2XCR and more JA openings for VK4YB

The details for July 26, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  That includes stations using fake or pirated call signs.  Please continue to be patient and let the FCC finish their processes.  UPDATED: 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.

Storms were slightly less wide spread but it remained very noisy across North America.  Oceania also reported high noise likely due to storms in the Tasman sea.  I suppose the good news is that in many areas where activity was limited by lightning, some of those stations have been able to return to air.

11-hour North American lightning summary


Geomagnetic conditions reached unsettled levels again for a single reporting period. The Bz is currently pointing to the South and solar wind velocities are currently averaging near 590 km/s.  During the evening that average was near 620 km/s.  The A-index is 9 which is down from the previous session but slightly higher than earlier in this session.   DST values remain the same, showing lots of variability but riding the centerline.




John, WA3ETD / WG2XKA, reported high QRN.  He provided reports for six WSPR stations and he was reported by eleven unique stations.

Neil, W0YSE/7 / WG2XSV, reported that his station, operating in a receive-only capacity, provided many reports each for WE2XPQ, WG2XXM, WH2XCR, WH2XGP, and WH2XXP.

Dave, N4DB, reported less noise and no storm threats during this session.  He provided reports for WG2XKA, WG2XXM, WH2XXC, WI2XUF, WH2XXP and ZF1EJ.  His best DX was at a distance of 3109 km.

Mike, WA3TTS, reported “Enough time slices between the static crashes to provide reasonable receive capability on 630m band for a change.  I used the NE, SW, and NW directions on the EWE antennas overnight in that progression. Started in NE direction, SW switched around 0300, NW switch around 0530 UTC. Nine stations decoded, including XGP best SNR -21 @ 0632 UTC, XXP best -9 @ 0812, ZF1EJ (Only 1 decode @ 0712), XXM best +1 @ 0640, XKA best -6 @ 0224, XUF -15 @ 0520, VE3CIQ -12 @ 0540, XXC best +5 @ 0536, XNG best -7 @ 0150.   Also ran dual band receive with converter IF port splitter for 13 WH2XND decodes, best -27 @ 1016 indicating higher QRN levels on 2200m.”

Hideo, JH3XCU, submitted this link detailing DX -> JA spot totals and peak S/N, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, reported “Quite high QRN from extensive storm system in the Tasman sea. Otherwise good conditions with the Pacific area looking busy.”  Roger received reports from N6GN,W7IUV, JA1NQI/2, JH3XCU, and 7L1RLL4.

Ken, K5DNL / WG2XXM, provided reports for three WSPR stations and he received reports from 35 unique stations including VK4YB, E51WL,  WH2XCR,  ZF1EJ, and three Canadian stations.

Larry, W7IUV / WH2XGP, provided reports for five WSPR stations and he received reports from 27 unique stations including E51WL and ZL2AFP.  As W7IUV, Larry provided reports for six WSPR stations including VK4YB.

Ward, K7PO / WH2XXP, received reports from 45 unique stations including E51WL, VK2XGJ, VK4YB, ZL1QM, and ZL2AFP.

This was a busy session at my station.  I listened for WSPR overnight with reasonably good success.  Noise was high but probably not much worse than recently observed.

WG2XIQ 24-hour WSPR activity


I also made major progress with my CW Skimmer / Reverse beacon network project.  As it turns out, there are a couple of things going on.  First, the programs need to be run as administrator, explicitly removing write protection for the data in the folder (there is an option in my very old version of XP).  Second, there is  a pattern matching file which does not have to be used but on 630-meters during the summer, not using the pattern matching means a potential for a lot of false decodes.  The problem with the file is that it does not contain pattern matches for all experimental call signs.  There is an override which requires a “maximum” number of calls and decodes to be reached before upload but I don’t know what that limit actually is.  I am going to work on this from a diplomatic standpoint to see if those patterns can be added to the file so this problem goes away.  Finally, CW Skimmer decodes just about any call sign that is present that can be heard.  It does a great job digging through noise.  But just because a signal is reported does not mean that it will be uploaded to RBN.  I am set to only upload call signs that begin with a CQ and it typically takes a “3×3  CQ” to trigger the process.  So my process is working well but I am running it on HF for now until I can get the pattern file situation resolved.

Eden, ZF1EJ, provided reports for three WSPR stations and he received reports from six unique stations.  Eden also reported that he was transmitting FT8 on 474.2 kHz + 1205 Hz at 0417z but no reports have been submitted at this time.  He added that he will plan on making transmissions each night. Watch the ON4KST chat for details.

ZF1EJ 24-hour WSPR activity


Warwick, E51WL, provided reports for eight WSPR stations by 1500z.  Report details (excluding WH2XCR who is detailed below) can be viewed here.

E51WL 24-hour WSPR activity


Laurence, KL7L / WE2XPQ, recently noted significantly more darkness and his reports reflect that fact.  He provided reports for three WSPR stations and he received reports from eight unique stations.  He shared two-way reports with WH2XCR.

WE2XPQ 24-hour WSPR activity


Merv, K9FD/KH6 / WH2XCR, provided reports for VK3HP, and VK5FQ and he shared two-way reports with VK4YB and WE2XPQ.  Merv received reports from E51WL, JA1NQI/2, VK2XGJ, ZL1QM, ZL2AFP, and ZL4EI.  His DX report details can be viewed here.  Seasons are definitely changing and the opening to JA is a major indicator.
