OFF AIR but returning after dark on Saturday night

Quiet terrestrial weather and quiet to unsettled geomagnetic conditions equal nice session but one that definitely favored North America; JD1 to be activated shortly by JD1AHC

– Posted in: 630 Meter Daily Reports, 630 Meters

Finally we found a quiet night in North America! For most of us, anyway.  There was some noise related to the hurricane in the Southeast but I believe that most of us by morning were in the clear and hearing something.  It was so quiet, in fact, that I had to check the receiver again.  I’ve not yet readjusted to the quiet conditions that this time of year can bring.

Geomagnetic conditions have been quiet although there was a spike overnight to unsettled levels which may have provided a bit of a spark for those of us at lower latitudes.  Laurence, KL7L / WE2XPQ, reported an overhead auroral arc at 0600z so things may not bode so well for him in the near term.  The Bz is currently pointing to the North and solar wind velocity in up from the previous session, averaging 410 km/s.  DST values continues to trend near nominal levels, although current levels are slightly negative.

WSPR reports over night suggest that the trans-Pacific path to VK was less reliable during this session.  In fact, Larry, W7IUV / WH2XGP, indicates that this session actually favored the eastern portions of North America more than the western Pacific path, something that has been very rare over the past few weeks.  He was decoded on 44 unique stations “…including a couple weak spots from VK4YB, ZF1EJ, and several east coasters.”  He decoded twelve WSPR stations”…including WG2XKA, VE3CIQ, and WD2XSH/15 using east BOG.”  Larry’s second receiver, listed under W7IUV, decoded nine WSPR stations “using West RX ant, did NOT hear VK4YB, first time in many days!”

John, WA3TED / WG2XKA, in Vermont reported a decent night dominated by North American reports as the trans-Atlantic path continues to be afflicted by the recent geomagnetic activity.  The high latitude transcontinental path offered some interesting results:

“Conditions are slowly improving after a very poor week.  The higher latitude path to the northwest reopened .  XKA was spotted by VE7KPB, a new one here.  VE7BDQ, VE7SL and WH2XGP also reappeared.  Overnight noisewas very low.  Overall, XKA heard 10 and was spotted by 22 stations.”

Ken, K5DNL / WG2XXM, operated the U3 into the amp in transmit-only configuration, which seemed to work well and freed up the K3.  He was decoded by 49 unique stations including “…WH2XCR@6007kn,WE2XPQ@4636km,VA7BBG@3189km.  Nice reports fm Eden(ZF1ED ) 155 decodes best +10 @ 2365km.”

Ward, K7PO / WH2XXP, was decoded by fifty unique stations including reports from VK4YB and VK2XGJ during a very “stingy” session:

Roger, VK4YB, issued a “code-3” for the session due to storms in the Tasman sea.  He indicates that DX S/N reports were in the high twenties.  Roger received reports from Japan, including first time reports from JA3TVF and a few other stations in western North America:

“Rx 2*wh2xgp (-28) 11*wh2xxp (-21) 9*wh2xcr (-21)

Tx 1*ve7bdq (-24) 2*ve7sl (-28) 3*we2epq (-13) 19*wh2xcr (-8) 11*jh1inm (-23) 4*ja3tvf (-20)”

John, VE7BDQ, reported at 0600z that in two hours of operating, he had been decoded by thirty unique stations and had decoded eight WSPR stations, including the previously reported VK4YB decodes.

Rick, W7RNB / WI2XJQ, reports: “Last evening conditions were much better at XJQ it would appear that things are improving again. However, there still seemed to be some limitations on reaching the East coast.”  Rick decoded ten WSPR stations and was decoded by 26 unique stations.

Doug, K4LY / WH2XZO, remained in receive-only capacity through this session because of high winds from the Atlantic hurricane skirting the coast.  He took the opportunity to run some receive antenna comparisons and offered these comments during the evening:

“Moderate noise here, but less lightning than expected. A/B/C tests. Wellbrook loop better toward favored direction to CIQ and XKA , but TX antenna better to XXM, XIQ, XXP. My unamplified 14′ by 28′ flag favoring northeast (loop is favoring N/S) is almost as good as the loop to CIQ and XKA so will construct a bigger flag! GN all…zzz’s.”

There will be more to this story as Doug continues his test and builds larger receive antennas.

Joe, NU6O / WI2XBQ, in response to a discussion on the ON4KST chat/logger by VK4YB about his 160-meter vertical being a disappointment compared to his wires, offered the following comments and links to related documents:

“…RE: your comment about dipole out performing a vertical. This is covered in the following BBC document: http://www.bbc.co.uk/rd/publications/rdreport_1970_07 .  Its not just the trees, at your latitude H pol will work better due to polarization coupling effects.  Here is another document on MF polarization coupling including multi hop paths: http://www.bbc.co.uk/rd/publications/rdreport_1964_03 .”

Hideo, JH3XCU, reported on the 600-meter research group that JD1AHC has been granted permission to operate from the Ogasawara Islands in the near future.  It unclear at this time which island will be on the air but Steve, VE7SL, reported that using google translate to deceifer http://6212.teacup.com/472khz/bbs/875 , it seems he will be using a 2E26 transmitter at 18-watts.  That may not sound like much but from this potentially quiet and remote outpost surrounded by sea water it may be enough for a number of ports of call to hear the signal and exchange reports.  This is exciting news… stay tuned!

I thought it was a good night from here in Texas.  Reception was good and signals were strong both on transmit and receive.  A number of CW levels were also noted, including reports from WH2XCR.  That CW QSO may be creeping closer.  My transmission reports can be seen here and my reception reports can be seen here.  There is a gap in reporting from just prior to 0900z until after 1100z when the WSPR PC crashed and I had to manually restart.

WSPR activity was consistently very high through the session.  At 0215z I observed 104 MF WSPR stations.  At 0400z I observed 106 MF WSPR stations and at 0517z, Ken, K5DNL / WG2XXM, reported 105 MF WSPR stations.  That is rare to have such consistency through a session will all of the “band hopping” that tends to occur.  It was a significantly larger audience than seen on 80 or 160-meters.

Laurence, KL7L / WE2XPQ, reported slight improvements on the longer haul paths early in the session only to observe aurora later in the evening.  Nevertheless, Laurence had a pretty good night of reports including VK4YB and WG2XXM.  Laurence added the following comments this morning: “Only fair to middlin’ last night with K=4 for part of night. Lake freezing and loads of moderate strength VLF whilsters at the moment.”

Merv, K9FD/KH6 / WH2XCR, experienced another big session with JA reports for JH1GVY and first time reports from JA3TVF.  As previously reported the path to VK was depressed so Merv received and provided limited reports with those stations compared to recent previous session.  Merv was not heard any further East than my stations during this session:
