OFF AIR for storms, probably for much of the week if the forecast holds

Wild, roller coaster propagation for North America with a variety of Summer noises reported still resulted in a pretty good session for May; DF2JP returns to MF with Hellschreiber; Solid openings between KH6 and Oceania; MF Solutions transmit converter giveaway registration ends tonight, drawing tomorrow – REGISTER NOW

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for May 12, 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.

THIS IS THE LAST DAY TO REGISTER TO WIN A MF Solutions 630-meter transmit downconverter!  Details and rules for submitting your name for consideration can be viewed here.  Registration ends May 12 at 11:59 PM EDT (tonight) and the drawing will be tomorrow!

It was an amazingly noisy night from very active storms that thankfully didn’t really begin to “crank up” until they were East of me.  I would argue that this session was truly representative of what mid-Summer actually can sound like on 630-meters.  Propagation was still there but as many observed, the longer openings are beginning later in the evening meaning that if you want to work evening QSO’s you better be a night owl.  Many of us are not but mornings seem to be productive when time allows.  Fortunately my time is about to open up for the Summer so maybe we will have a QSO through the noise.  W7IUV reported high broadband noise in Washington state not associated with QRN or power system-related QRM.

Geomagnetic conditions continue at quiet levels.  Elevated protons returned through the day, settling overnight.  The Bz is pointing to the North and solar wind velocities are averaging near 370 km/s.  DST values continue to look very hopeful.




Joe, DF2JP, reported that he was QRV again on 630-meters after some time on LF.  After a problem with his top loading a few weeks ago, he found that he needed to add an addition 9 uH to resonate the system within the band.  He operated Hellschreiber for part of the session and noted that the TS-590 is working well with his amplifier.

Al, K2BLA / WI2XBV, reported moderate noise in Florida.  He decoded six WSPR stations and was decoded by fifteen unique stations including WH2XCR plus three other that are near or in excess of  4000 km.  Al indicates that he continues to operate at reduced power.

Doug, K4LY / WH2XZO, reported “QRN levels and 630M results similar to night before with 10 unique decoded and 25 decoding XZO including two VE6s for best DX.”

John, WA3ETD / WG2XKA, reported that he was QRV all night, decoding nine WSPR stations and receiving reports from 21 unique stations.

Dave, N4DB, reported that he was listening again before sunrise after a stormy night in Virginia.  He decoded ten WSPR stations although none of them were in excess of 3000 km.

Ernie, KC4SIT / WI2XQU, reported that he was decoded by 21  unique stations overnight:

David, N1DAY / WI2XUF, presented these observations for the session:

“The Carolina’s chapter of the Cellar Dwellers had a good time scratching our heads over propagation patterns last night.  By 10PM Doug – WH2XZO in Inman SC was racking up WSPR spots while Ernie – WI2XQU and myself (listening as N1DAY) at the Upward Signal Acquisition Center had virtually nothing.   This didn’t make a lot of sense because the night before, under similar conditions, all three of us were roughly identical in both send and receive reports.
Reflecting back on things, I remembered that 2 nights ago, our propagation was almost all north/south and that I had looked up the lightning activity map at Lightningmaps.org and found a wall of intense lightning activity stretching from central Mexico the whole way to Ohio.  Sure enough it was there again, although the lightning activity only extended as far north as Eastern Tennessee with one pretty massive cell leading that system sitting just north of Asheville NC and another cell in North Central NC.
At our respective QTH’s both Ernie and I are due south of Asheville, about 20 miles by crow flight measures with Doug being to the south and west of us by about 30 miles.   When we started to look at Doug’s spots relative to ours, it became apparent that we had to go through the lightning activity north of Asheville while Doug was threading the needle and getting spots between the storms north of all of us.
By midnight, this had all changed.  The storm in Asheville had dissipated, and both Ernie and I started to make contacts that Doug had gotten earlier in the evening.  By early morning, the wall of lightning west of us started to dissipate into Louisiana, and that cleared the way for a few contacts to the west and NW.
All in all, given the evolving storm conditions last night, the Cellar Dwellers here in the Carolinas did pretty good and my new listening antenna seems to be doing its job.”

Al, WD4AHB, reported that “It seemed like a pretty productive night for me, overall I had 175 spots over the monitoring period with a total of 7 unique. QRN levels were still pretty low. M74LOV appeared again with several others spotting it as well.”

Mike, WA3TTS, reported “12 stations decoded overnight. I ran the NE EWE antenna until about 0900 and then switched to NW EWE antenna through sunrise for QRN management purposes…”  Mike provided the following statistics:

Hideo, JH3XCU, posted links to two tables showing VK -> total JA DX  and VK -> JA peak S/N for the session.

Roger, VK4YB, reported “Poor conditions, only one spot from NA courtesy of Larry, W7IUV. Later some JA reports. QRN was low.”  He received reports from 7L1RLL4, JH3XCU, JR1IZM, W7IUV, WH2XCR.

Larry, W7IUV / WH2XGP, provided reports for seven WSPR stations and he was decoded by 33 unique stations.  As W7IUV, Larry provided reports for six WSPR stations including VK4YB.

Well before sunset with storms more than 90 miles away, I could hear extreme lightning noise in spite of the transmit antenna being set to the “detuned” position as I leave it when not in use.  It sounded like July!   Propagation at my latitude was pretty good and more stations decoded my reduced power and duty cycle signal than I expected.  Those report details can be viewed here.  My receive numbers were down as expected but were reasonable for listening omni through these types of noise conditions.  Report details can be viewed here.

After additional input and scrutinizing, here is the current draft of the recommended band plan for use under Part-97 rules once the band opens.  Fritz Raab has made adjustments and clarifications to the foot notes.  Please keep in mind that the goal is to avoid over-regulating the band.  There is a preponderance of evidence suggesting that a majority of operators prefer a “hands off” approach while protecting weak signal modes from wider modes.

Eden, ZF1EJ, provided reports for eight WSPR stations and he was reported by sixteen unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, reported a potential for stormy weather in Alaska which may have increased his noise level a bit overnight.  This session was comparable to the previous where Laurence shared two-way reports with WH2XCR and received reports that were generally located in the Northwest.

Merv, K9FD/KH6 / WH2XCR, had these comments about the session:

“About normal overnight WSPR,  had a lot of QRN again, but it does not seem to bother decodes all that much..

Amazing VK4YB reported me at 1618Z,  my sunrise now is 1550Z ,  this is well after sunrise by 30 mins.   Really amazing at times how the VK to KH6 path is open.  Thanks to Roger for his daily operations.”

He provided reports for VK5FQ, VK3HP, and ZF1EJ.  He shared two-way reports with WE2XPQ and VK4YB and he received reports from EJTSWL in Tasmania, VK2XGJ, ZL2AFP and ZL1BPU.  On the East coast of North America, Merv reported WI2XBV.  DX report details can be viewed here.
