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 in the Southeast through the mid-Atlantic region created a lot of noise during this session. The West was much quieter from here in North Texas in spite of a few storms through Oklahoma, Kansas, and the panhandle of Texas. A few strong storms were also present during the evening in Manitoba and Ontario and remain strong this morning through parts of the northern peninsula of Michigan, Minnesota and Wisconsin.
Geomagnetic conditions reached storm levels again just as it was looking like the magnetic field was beginning to relax. The Bz is pointing to the South this morning and solar wind velocities are averaging near 580 km/s. The A-index tells the real story here as it remains around 20. DST values are depressed with numerous deep decreases reported through the session. I’m not going to guess when these conditions will recover but numerous enhancements have been observed through this event.
For what it’s worth, in spite of active geomagnetic conditions, there seems to be more than enough spark to provide good propagation for many stations at lower latitudes. I suspect that high latitude stations may struggle until the A-index can come down significantly. Laurence, KL7L / WE2XPQ, typically prefers an A-index under 8 in Alaska. Hopefully a few stations at mid and lower latitudes can take advantage of the more active conditions and make a few connections.
David, G0MRF, reported that he has been away from home for a month so it was nice to be home again and active on the band between 1900 – 2100z during this session. He experienced pretty good results and offered these comments and statistics:
“…September certainly seems an improvement on a month ago, but there are still sporadic thunderstorms adding to the noise level Heard only 5 with a receiver some miles North of my location using a loop antenna oriented N-S. Not too surprising as it has a null towards Germany to my East However, Heard by 44 unique stations with 10 over 1000km. The best being OH6JKN at 2027km with signals from -18 to -24dB.
I also spent around 20 minutes calling CQ on 472.60, listening for replies on the 200ft sloping wire used for transmitting. This generated a single response by a station which was frustratingly at the same level as my high local noise level here in West London. Even so, it was nice to get the equipment warmed up and see so many receive stations monitoring the band.“
Doug, K4LY / WH2XZO, reported a chilly morning in South Carolina after evening storms that significantly increased his noise levels. He received reports from 33 unique stations including VE7SL and he reported eight WSPR stations.
John, WA3ETD / WG2XKA, indicates that noise was higher than he expected in Vermont. He provided reports for seven WSPR stations and he received reports from twenty unique stations. John also has an article in the September edition of CQ magazine on the topic of variometer construction. He did a nice job and included all of the details that are necessary to get the job done right.
Rick, W7RNB / WI2XJQ, provided reports for six WSPR stations and he received reports from 22 unique stations.

Al, K2BLA / WI2XBV, provided reports for eight WSPR stations before he succumbed to strong storm noise in his region.
Mike, WA3TTS, reported that he decoded twelve WSPR stations overnight through moderate QRN. His session best DX was WH2XGP at -16 dB S/N 0502z. He also provided one decode for ZF1EJ decode at -24 dB S/N at 0240.
Dave, N4DB, reported that he decoded ten WSPR stations through very high noise in the East.
Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.
Hideo, JH3XCU, posted the following statistics showing 472kHz WSPR-2, DX->JA Spots per Day for the period of July 1 – August 31, 2017. Its nice to see the pronounced up-tick in activity near the end of the reporting period:
Roger, VK4YB, indicates “Quite persistent but low level QRN seems to be coming from the Western Pacific and Indian Oceans. Receiving conditions were not good. I bagged WH2XCR, WH2XGP, and WH2XXP shortly after sunset then absolutely nothing else for the rest of the session. Lots of spots on the transmit signal but mostly low level. Best from Hawaii was +2dB, -16dB from NA and -18dB from Japan. There was no sunrise enhancement along the West coast.” Roger received reports from 7L1RLL4, EJTSWL, JA1PKG, JA3TVF, JE1JDL, JH1INM, JH3XCU, TNUKJPM, VE7BDQ, VE7SL, W7IUV, “WA6OURWIKI”, WD2XSH/26 and WE2XPQ. He shared two-way reports with WH2XCR and WH2XGP.
Ward, K7PO / WH2XXP, reported at 0527z that he had already been reported by 48 unique stations including ZL2AFP thirty minutes before sunset in New Zealand. By morning, Ward received reports from 61 unique stations including ZL1EE, ZL2AFP, VK4YB, VK2XGJ, VK2EIK, VK3GJZ, VK3ALZ, VK3WRE and VK7TW.
Larry, W7IUV / WH2XGP, indicates that conditions were up and much better. He provided reports for twelve WSPR stations including ZF1EJ and he received reports from forty unique stations including ZL1EE, ZL2AFP, VK2XGJ, and VK3WRE. He shared two-way reports with VK4YB. As W7IUV, Larry provided reports for twelve WSPR stations including VK4YB. He also indicates that he is using the full-size transmit antenna again.
I started the session on CW, making a few calls on 474.5 kHz during the evening as I tested a few new tools in the shack. It was very noisy and I didn’t expect much. I transitioned to WSPR for an hour at 0144z and heard quite a few stations in spite of high noise. Storms to the East were the dominating noise feature for the session as the Southeast was pounded again. I QRT’ed for the night at 0244z. The morning began with CW at 1018z but QRT’ed at 1030z due to high noise from the East. I transitioned to WSPR through sunrise and was pleased to share two-way reports with WH2XCR and also received a report from ZL2AFP. I’ve been operating at about 25w TPO for WSPR which translates to just over 1W ERP on my system under current metrics in one or more directions. A clear sunrise peak was observed with WH2XCR reports and I was hopeful that the peak might correspond with a VK4YB transmission but it does not appear to have occurred. I received WG2XSV’s 23 dBm this morning, which was a nice surprise and a number of Pacific Northwest stations peaked on the approach to sunrise. Propagation was very good during this session at my station and noise conditions improved significantly after the southeastern storms were in full daylight. Its remarkable how the band feels like someone flipped a switch. Of course at my latitude the geomagnetic conditions are providing a bit of an enhancement. My WSPR transmission report details can be viewed here and my WSPR reception report detail can be viewed here.
Regional and continental WSPR breakdowns follow:
Eden, ZF1EJ, provided reports for four WSPR stations. He received reports from thirteen unique stations including WH2XCR. Based on reports from the lightning map, noise conditions were very poor in the Caribbean.
Laurence, KL7L / WE2XPQ, returned to air after his son was able to repair the vertical wire connection to the ATU while Laurence is away. He provided reports for four WSPR stations including VK4YB and he received reports from seven unique stations. He shared two-way reports with WH2XCR. DX report details can be viewed here.
Merv, K9FD/KH6 / WH2XCR, provided reports for twelve WSPR stations including VK3HP, VK5ABN and ZF1EJ. He shared two-way reports with VK4YB, ZL1EE and WE2XPQ. Merv received reports from 32 unique stations including JH3XCU, EJTSWL, VK2EIK, VK2XGJ, VK3ALZ, VK3GJZ, VK3WRE, VK7TW and ZL2AFP. DX report details can be viewed here.
