Propagation was good during this session but based on a review my reports, QSB and QRN dominated at many receiving stations through a number of reporting periods. The Midwest was particularly active with storms during the evening but many stations were able to operate for a portion of the session. Storms in the Gulf of Mexico and Minnesota were the primary QRN sources as the session progressed towards sunrise.
Geomagnetic activity was very quiet during this session with a Bz ranging from unity to slight South-pointing and solar wind velocities were near 350 km/s. Solarham is reporting a geoeffective coronal hole rotating into view today and G1 storm levels are possible over the coming sessions. DST values are showing a characteristic increase that seems to occur before “the bottom drops out”. Perhaps the onset of an event will occur at a time that is advantageous for good propagation:
It was nice to have WH2XZO running at partial QRO power levels again. He was decoded here a number of times through the night and was hearing well as K4LY. Doug reports just a bit more antenna work remains but he is already doing well at less than half power.
The CLE event wrapped up overnight and interestingly enough there was a surge of activity by European stations. A few excerpts that were posted on the RSGB reflector follow:
“CW Beacon G3WCB is now transmitting on 476.2 kHz for the CLE. 50 seconds of carrier, followed by 12 wpm CW i/d. Power about 10watts RF into a 10m sloping wire at 6m height. Transmissions will (hopefully) continue until tomorrow morning.
73, Dave G3WCB IO80EI.”
“LA1BCNis inn with QSB….and a lot of lightning crashes…… I will continue all night with LA3EQ CW beacon on 476.4kHz.
“Hi all you beaconeers,
up to now (2040 UTC) no traces from LA1BCN (476.5 kHz), LA3EQ (476.4 kHz) and G4WCB (476.2 kHz) her in JN59WK in spite of QRN being less than yesterday, spikes now about S5 maximum.
But IQ2MI (JN45NL) is good visible/audible here as usual with S4/5 at Perseus with earth dipole.
Want to go to bed now – gl es cuagn!
From the ON4KST chat/logger, several stations posted reports of their activity in the CLE event:
|03:02:47||VA7MM Mark||Slow CW beacon again tonight on 475 kHz. Running high power this time, about 100 W into a marconi T antenna.|
|03:13:21||WG2XSV Neil||Mark/MM starting to hear and see ur cw but very weak.|
|03:24:25||WG2XSV Neil||Ward, cpy ur XXP cw ID 559|
|03:22:35||WG2XSV Neil||Darkness make the difference Mark|
|03:21:53||WG2XSV Neil||Mark, I copy ur CW now 539|
|03:27:16||WG2XSV Neil||Toby, cpy ur CW on 477.6 at 559 . Nice trace|
|04:32:33||VA7MM Mark||Neil, just sent a beaon recdording from Firday night. Will listen again for you on 473 kHz. 73.|
|04:25:49||WG2XSV Neil||Gotta hit the sack now..73|
|04:24:48||WG2XSV Neil||Mark, I moved my beacon down to 473 kHz for the rest of the night. Hope you can hear it there.|
|03:53:39||VA7MM Mark||Neil, listened briefly for your beacon on 475.2 kHz but did not hear anything. Will try later. Locals are strong with VE7BDQ at S9 and VE7CNF at S9+10.|
|03:45:51||WG2XSV Neil||RRR tnx Mark.|
|03:44:19||VA7MM Mark||Neil, thanks for the report. I have a recording of your signal from Friday night that I will send.|
|03:33:28||WG2XSV Neil||wg2xsv CW beacon now on. QRG 475.2 kHz|
|06:07:42||VA7MM Mark||Also hearing WG2XSV beacon 559. Just made a recording.|
|06:02:10||VE7CNF Toby||Hearing WG2XSV beacon 473.1 about 449 with static crashes.|
Laurence, KL7L / WE2XPQ, operating portably from W7, provided the following signal reports:
“bdq 589 cnf 579 va7mm 599 peaks, xsv 559 qsb – cw id of xgp 599”
Larry, W7IUV / WH2XGP, reports that he decoded five WSPR stations, including VK4YB, and was decoded by 25 unique stations including four VK stations. Larry indicates that propagation to the East continues to be weak for him:
Larry also reported that he has been evaluating an SDRPlay RSP dongle receiver recently. Long story short: it is not a good solution for MF and LF. He notes that with enough good low pass filtering and a preamp, it might be usable.
Ron, W6XY, reported VK4YB, for what is believed to be the first time. And he did so seven time. Well done!:
Rick, W7RNB / WI2XJQ, reports that his amplifier and combiner repairs are complete and he is back on the air at full power. He provided the following detailed statistics for the session from his station:
Ward, K7PO / WH2XXP, was off air for the overnight period as he did not complete changes to the system tuning. He was active during the early evening.
Roger, VK4YB, reports that he has been chasing a noise source that is present day and night over the past few weeks. It is believed that the noise is coming from power lines and he has built a portable ferrite loop stick probe tuned to 475 kHz in order to search for it. The preamp draws only 1.5 mA and he uses his Elecraft KX3 as a receiver:
Regional and continental WSPR breakdowns follow:
There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths. UA0SNV was present but no reports have been filed at this time.
Eden, ZF1EJ, operated two receivers and two antennas and was successful at decoding WH2XZO and WG2XIQ in spite of high Gulf QRN:
Laurence, KL7L / WE2XPQ, continues to decode VK4YB and WH2XCR on two receivers / antennas. The differences between each receiver / antenna are particularly interesting during this session:
Merv, K9FD/KH6 / WH2XCR, decoded VK4YB once again and was decoded by VK2XGJ, VK2DDI, VK4YB and JA1NQI-2 in addition to North American stations. I was happy to see Merv’s signal here once again:
Jim, W5EST, presents “RRR: REMOTELY RE-VIEWABLE RECEPTIONS, MORE NOTES ON SCREEN-SHARING”:
“Aug. 24-26 have introduced the idea of RRR for JT9 and using the Join.Me™ screen-sharing app for that purpose. http://www.joinme.com Today’s illustration depicts an example of screen-sharing with point-to-point chat via Join.Me as described Aug. 26. One-way works just fine with a minimum of effort. The host’s PC sends its screen to the participant’s PC for viewing.
When I download Join.Me to both PCs and try to send an invitation from each PC to the e-mail address accessible by the other PC, an attempt to accept the second invitation is greeted with a simple message that Join.Me is already installed on that PC. One can go around this greeting, however, by clicking on a link at bottom of the message that suggests you connect through your browser. If I can achieve further success with this two-way setup, I’ll report further and illustrate it in another blog post. (I see no Join.Me menu option to include a participant’s screen in the host PC’s screen in a single meeting.)
How can one make the most of at least the convenient one-way features of Join.Me to promote and enhance JT9 QSOs? Stations in the same geographic region—like West, or Mid-South, or Southeast, or Northeast–in a continent can “buddy up.” That way, a given TX1/RX1 JT9 station is helped by one or more RX2-only stations in that region to bring about more 630m JT9 QSOs. We can begin to achieve 630m JT9 QSOs over longer-distances that can span most of a continent and finally all of it, and prove 630m JT9 DX performance at last!
Preferably an RX2-only station acting in this capacity has at least comparable RX antenna performance to what the TX1/RX1 JT9 station has. Then 630m spotlight propagation and general SNR randomness in each JT9 time slot delivers decodes from RX2 by screen-sharing over to the TX1/RX1 JT9 station for that 630m op to achieve more QSOs over longer distances. Meanwhile, the RX2 station operates with normal viewability and performance on the RX2 PC.
Stations can use the ON4KST reflector to arrange for screen-sharing or whatever way they like. The 630m RX2-only station downloads the Join.Me app. In Join.Me lingo, the 630m RX2-only station then e-mails an invitation giving a meeting code to the TX1/RX1 JT9 station. That station uses the meeting code to knock to join, which the RX2-only station accepts. At that point, the RX2 JT9 screen becomes visible at TX1/RX1 JT9 station to receive decodes that it was not otherwise able to obtain due to the vagaries of 630m propagation.
What do you think? Will you try this RRR method to enhance JT9? Tell us your thoughts, plans and experiences! GL on JT9!”
