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

The 2017/2018 season begins with mixed results for domestic and trans-Pacific openings; Trans-Atlantic remains missing; Geomagnetic conditions trying to recover but DST values remain depressed; W7IUV testing small backup transmit antenna

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for September 1, 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.

The opening of the new season was noisy with lots of storm activity in the Gulf of Mexico into the Southeastern US and the West to points North into Manitoba and Saskatchewan.  The noise did not subside by morning this time.

11-hour North American lightning summary


Geomagnetic conditions continue at G1 storm levels although this event may be starting to wind down based on the reported Kp. The Bz is pointing to the South this morning and solar wind velocities averaged near 650 km/s.  DST values are now off of the lows but it is possible that additional decreases will be observed as negative levels persist.




Propagation was interesting as it seemed to cool at higher latitudes, which may be a function of the deteriorated DST levels, while performing well at lower latitudes. Stations in the East and Northeast reported a relatively lackluster session but stations in the West experienced better propagation and band conditions, in general. Trans-Pacific propagation on 160-meters was excellent but openings on 630-meters can go either way under such band conditions.   You cast your net and hopefully you drag in something good.

John, WA3ETD / WG2XKA, indicates that he provided reports for five WSPR stations and he received reports from sixteen unique stations.  John added that noise was low but there was not much propagation in Vermont resulting in a below average session.

Doug, K4LY / WH2XZO, reported that “Despite fog, drizzle and 100% humidity we transmitted all night with 30 decoding XZO including WD2XSH/26, 3480 km, for first time this season. Only 11 decoded here.”

David, N1DAY / WI2XUF, reported “Lots of QRN here last night.  I generated a total of 35 unique spots (10 RX, 25 TX) with 8 of the stations receiving my signal being greater than 1000 km distant.  Still refining the antenna and experimenting.  Last night I started dressing out the 6 verticals that make up my cage.  Got them all tangled up and ran out of daylight, so I just soldered the ends of the tangled mess back to the inductor.  Was really surprised that this worked.”

Al, K2BLA / WI2XBV, indicated that he experienced moderate QRN this morning after unexpected overnight storms.  He provided reports for nine WSPR stations and indicates that weather conditions may keep him off air for a few days.

Mike, WA3TTS, reported that he decoded twelve WSPR stations overnight, including WH2XCR at 0854z.  All of his reports were from the Northwestern EWE antenna.  Mike provided a few additional comments and statistics:

“I listened for LW BC stations about 1/2  hour past SS to the NE, but no audible modulation detected from them…So I stayed on the NW EWE antenna all night for 630/200m split IF receive.

WH2XCR         1 decode @ 0854 -25
WH2XGP        13 decodes, best   -16 @ 0810, min -25 @0708
WH2XXP        84 decodes, best    +4 @ 0742, min -22 @ 0218
ZF1EJ               9 decodes, best  -21 @ 0448, min -23 @ 0648
WG2XXM      90 decodes, best  +8 @ 0518, min  -20 @ 0126
WD2XSH/15  27 decodes, best  -13 @ 0852, min -24 @ 0526
WG2XKA      41 decodes, best  +8 @ 0416,   min -18 @ 0016
WI2XRM         1 decode @ 0204 -24
WI2XSV        71 decodes, best   +5 @ 0520, min -22 @ 0024
WH2XZO      92 decodes, best   0 @ 0944,  min -23 @ 1040
WI2XUF      150 decodes, best  -3 @ 0712, min -23 @ 0422
WH2XXC     90 decodes, best   +8 @ 0436, min -26 @ 0052

Also 110 WH2XND decodes from 0212 to 1136 utc, best -15 @ 1004, min -32 @ 1136.  630m/2200m comparisons with WH2XXP interesting as first decodes occurred at the same time. Usually XND decodes 30 to 60 minutes later than XXP.

WH2XND  0212 @ -30
WH2XXP   0212 @ -22

Last XND decode -32 at 1136 vs last WH2XXP decode at -13 @ 1048″

Dave, N4DB, reported that he decoded ten WSPR stations overnight.

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, submitted that “The evening started poorly. No spot of WH2XXP until 2 hours after sunset and WH2XCR was weak. It looked like a fizzer. But later the band took off big time. A spotlight was illuminating the VE7 area, but never reached the Alberta twins. Then out of the blue a report from WG2XIQ, when there was no sign of WG2XXM and the top report for WH2XXP was only -21dB. The spotlight stayed in the VE7 area until near sunrise when it moved South and the W6’s joined the party. At the same time there was a good path to Japan. After West coast sunrise, I switched to the JA beam and improved my reports with a -19dB from JH1INM.”  He received reports from 7L1RLL4, JA3TVF, JE1JDL, JH1INM, KK6EEW, N6GN, VE7AB, VE7BDQ, VE7SL, VE7VV, W7IUV, “WA6OURKIKI”, W6SFH, WE2XPQ and WG2XIQ. He shared two-way reports with WH2XCR.

Ken, K5DNL / WG2XXM, provided reports for eight WSPR stations and he received reports from fifty unique stations including ZL2AFP, WH2XCR, ZF1EJ and eight Canadian stations.

Joe, NU6O / WI2XBQ, provided reports for six WSPR stations and he received reports from 29 unique stations including ZL2AFP, VK2XGJ, and VK4YB.  He added that the trans-Pacific path was good for him and noted “several new listeners including WB6RQN near San Antonio 2595Km, my best DX to the East this season.”

Ward, K7PO / WH2XXP, received reports from 63 unique stations including ZL2BCG, ZL2AFP, VK4YB, VK2XGJ, VK3ALZ and VK7TW.

Larry, W7IUV / WH2XGP, indicated that yesterday he would be testing a smaller antenna and reports that the “New backup TX antenna had good “local” performance, no DX/East Coast. It’s mostly horizontal so no low angle…Horizontal antenna sure not good for DX!”  The antenna is a 450-foot long wire that shares the radial system with Larry’s 160-meter vertical and then rises on a diagonal to 66-foot above the ground to one of his towers and then returns to an endpoint pole for a balance of the distance.  The antenna is configured like an end-fed inverted-V.   Larry provided reports for sixteen WSPR stations and he received reports from 32 unique stations. As W7IUV, Larry provided reports for nine WSPR stations including VK4YB.

I started the session feeling exhausted but I was determined to call CQ for a bit on 474.5 kHz CW starting at 0230z.  I admit that I was falling asleep at the key but somehow kept it going until 0300z.  I’m not sure that I would have had the energy to pull out any call signs.  It was a typical noisy evening and just shows why I prefer mornings.  At 1100z I started WSPR with the intention of running for an hour to sunrise.  VK’s were strong on 160-meters so I wondered if the same might be said on 630-meters.  I was not disappointed.  At my sunrise VK4YB was blazing in here at -25 dB S/N which may be the best report I have ever provided Roger.  It was also nice to share two-way reports with WH2XCR.  I am very hopeful for this coming season.  Operating one hour at 33% transmit cycle, domestic conditions were quite good, including reports into areas that were into daylight.  Its been nice to run these abridged WSPR sessions that focus on the times of day when propagation and noise are best for me here in North Texas.  My transmission report details can be viewed here and my reception report details can be viewed here.
