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

A surprise X8.3 flare produces a big CME from a limb that may still find its way to Earth; VK4YB -> central US, including KU4XR in Tennessee; Trans-Atlantic path continues to show life with WH2XXC -> EA8BFK

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.

It was a relatively quiet session as evening storms from the Desert Southwest into Mexico dissipated overnight.  A strong cluster of storms was observed in southern California and the activity in the southeastern US related to hurricane Irma continues.  A system in north central Canada is progressing to the East.

Geomagnetic conditions  were a bit of a surprise.  An X8.2 flare was reported around 1600z which was accompanied by a radiation storm.  While the event occurred on the western limb of the sun, it was reported to be so massive that there is an Earth-directed component and CME which may arrive by September 12.  Proton levels skyrocketed after the flare but so far geomagnetic conditions have only reached unsettled levels.  The Bz is pointing slightly to the South this morning and solar wind velocities are averaging near 290 km/s.   DST values are currently “safe”, riding the centerline as they continue to show improvement but I expect the bottom will fall out if this CME arrives as expected.

Session trans-Atlantic activity


Rob, K3RWR / WH2XXC, provided reports for nine WSPR stations and he received reports from 36 unique stations including EA8FKB.

Doug, K4LY / WH2XZO, reported:

“Some return to better conditions despite the QRN from Irma.  The 36 who decoded XZO included WH2XCR for the first time in over a week.  WH2XGP was a decode both ways and one of the 10 we decoded.

It’s a real plus to have an African station with good ears on 630M WSPR this season,  EA8BFK will probably decode many North American stations despite being north of some of them and on the east side of a mountainous island.  I’ve long said a more southerly path to say Cape Verde Islands or even coastal Brazil would be more comparable to the west coast VK/ZL paths, and I hope we some day get the opportunity to see if that is true.”

Rick, W7RNB / WI2XJQ, reported that “Conditions seem to be a bit less than last session, signals appear to  be down a little.”  He provided reports for seven WSPR stations and he received reports from eighteen unique stations.  Rick’s unique report details can be viewed here.

Ernie, KC4SIT / WI2XQU, indicated that the hurricane impacted his operation just a bit:

“Rain from Hurricane Irma started at the WI2XQU QTH approximately 2 hours before start of transmission last session which drove up my SWR (1.5:1 vs the usual 1.1:1) and lowered the output on the Monitor Sensors transverter by approximately 10 watts. I was again in transmit mode only thought I copied WH2XXC again this session “off the coil.” He is 406 miles from me with me providing his station with 6 decodes through the session. WH2XZO is 40 miles from me and is heard in Hawaii but not at WI2XQU. Seems strange to me. Another thing I noticed about the WH2XZO signal is shown in the block of 9 grid squares below. Both Doug and I were decoded in FN34, FN33, FN42 while only Doug was decoded in FN43 (WE2XGR). “Skips” of grids such as this continue to puzzle me and remain the focus of my attention. If anyone has a thought on this…

In final tally I was decoded by 32 stations and my signal was heard to the south, regardless of Hurricane Irma, by ZF2EJ. Regular monitor and decoder of WI2XQU, Al WS4AHB of north Florida was QRT for the storm this session.”

David, N1DAY / WI2XUF, reported that he:

“…was in RX only mode again last night on my 6 element Eiffel tower antenna.  It continues to perform well with 11 spots last night .  Most distant was WH2XGP out in Washington State.   I did a little auditory and visual A/B comparison of the Tower to my single element inverted L using the JT modes and discovered that the 6 element tower smokes the inverted L even though the inverted L is 10 ft higher up in the air.  I am going to rewire my station today with an additional relay to allow the new antenna to do both TX and RX duties on 630M.”


Mike, WA3TTS, reported that he decoded ten WSPR stations overnight, including session “best XXP -7 @ 1018. 67 ZF1EJ spots best -9 @ 0310, no PNW, XIQ MIA”

Dave, N4DB, reported that he decoded eleven WSPR stations.

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

Roger, VK4YB, wonders “if the “Mackerel Sky” has rotated slightly.  The path to Tennessee opens but the normally strong path to PNW is nearly gone.  At the same time a strong path from Hawaii to Japan opens but the path from VK to Japan dies. Will it rotate back tomorrow?”   He received reports from CF7MM, KU4XR (first time report), VE7SL, W7IUV and WH2XGP. He shared two-way reports with WH2XCR and WG2XXM.

John, VK2XGJ, reported that it was almost like WH2XXP had relocated to South of the equator with reports fifteen minutes before sunset in VK2:

Andy, KU4XR, was excited to report his reception of VK4YB during this session at -29 dB S/N at 1114z.  He provided reports for a total of thirteen legitimate stations.

Ken, K5DNL / WG2XXM, provided reports for eleven WSPR stations and he received reports from 49 unique stations including VK2XGJ, ZL2AFP, ZL1EJ and five Canadian stations.  He shared two-way reports with VK4YB  and WH2XCR.

Ward, K7PO / WH2XXP, received reports from 63 unique stations including EJTSWL, ZL2AFP, ZL4EI, ZL2BCG, ZL1EE, VK4YB, VK2XGJ, VK2EIK, VK3ALZ, VK3GJZ, VK3WRE, VK5ABN and VK5AKK.

Larry, W7IUV / WH2XGP, provided reports for thirteen WSPR stations and he received reports from 39 unique stations including EJTSWL, VK2XGJ, VK2EIK, ZL1EE, ZL2AFP, ZL2BCG and ZL4EI. He shared two-way reports with VK4YB.  As W7IUV, Larry provided reports for fourteen WSPR stations including VK4YB.  He indicates that there is “still lots of hi-lat absorption going on, good path to ZL from here, not quite as good to VK. Little east coast making it through.   Hard to hear at moment due to TX antenna “de-tune” not operational yet. Causes 6-10 dB RX degradation.”

Laurence, KL7L / WE2XPQ, received a booster on Sunday for recent high absorption but still managed to decode WH2XCR.  As G4DMA/A functioning in a receive-only capacity while in England, Laurence provided reports for five WSPR stations.

Merv, K9FD/KH6 / WH2XCR, provided reports for thirteen WSPR stations including VK3HP, VK5ABN and VK5FQ. He shared two-way reports with VK4YB, ZL1EJ and ZL1EE. Merv received reports from 39 unique stations including 7L1RLL4, EJTSWL, JA1NQI-2, JA3RVF, JA3TVF2, JH3XCU, VK2EIK, VK2XGJ, VK3ALZ, VK3GJZ, VK3WRE, VK5AKK, VK7TW, ZL2BCG, ZL4EI and ZL2AFP.   DX report details can be viewed here.
