Southern parts of North American experience strong storms from Texas to Florida and along the Gulf coast.  Western Europe continues to experience storms while strong Mediterranean storms are progressing to the East.  Isolated storms were present into northern Europe.  Isolated storms were observed in central Japan and like the previous session, eastern and southern Australia is mostly storm free with the bulk of activity in the North and West.  New Zealand was storm free.

Geomagnetic conditions are quiet. The Bz is pointing to the North this morning and solar wind velocities are averaging near 415 km/s. DST values remain above the centerline at positive level and are slightly less variable than the previous session.

Paul, N1BUG, made attempts at a trans-Atlantic JT9 QSO with G3KEV and others during this session but was unsuccessful this time.  Both Paul and Mal heard one another but never at the same time at strong enough levels for a QSO.  They will eventually get it done.  Mal first reported Paul at -26 dB S/N at 2335z but Paul did not decode Mal until 0027z and again at 0052z at -25 dB S/N.  A spur report resulted in some lost time while Paul investigated the problem.  On the RSGB-LF reflector, Paul added that,

I decoded PA0A calling me several periods but he did not respond to me sending reports.

I decoded G3KEV calling me just once but saw him on the waterfall for several periods.

Then I got a report of bad spurs on my signal (only 23 dB down) with a screen shot to prove it. It looked very bad so I stopped transmitting. Shortly after that I decoded a CQ from G3KEV at -25.

G3KEV was decoded by other North American stations also.

PSK Reporter and me do not get along well, I find it nearly impossible to figure out what it’s trying to tell me. Usually I just end up grinding my teeth and growling at it !  However I believe my JT9 signals were heard by several other stations in EU.

Subsequently I did some testing regarding the report of spurs. They appear to be more than 50 dB down in my own receiver. However I do not trust local measurements as overloaded receivers can do strange things. I ran WSPR for a while with the exact same setup I use on JT9. I received reports up to +15 but not a single double decode. So it remains a mystery what happened earlier when I had the bad report. As far as I can tell I am clean.

Anyone up for another night of JT9 or perhaps QRSS? I have never used QRSS but am willing to try that mode.

This morning Paul posted these comments indicating that he will try again tonight.

 

Mal, G3KEV, had these comments about the trans-Atlantic JT9 test:

“Yes decodes in both directions but unfortunately no QSO. Another time maybe tonight.  If you saw me on your waterfall then QRSS would have worked ie QRSS 10 or less, possibly QRSS 3.  Surprised other NA stns who decoded me did not call in or try.


Sometimes when a signal is strong there can be more than one decode by other stations close by, often their RX is the problem and not the TX station.  I have noticed this around EU also and one station receiving a strong plus dB signal gets two decodes whereas another receiving the same strength signal only gets the strong signal decode, this would indicate that there are RX problems at some locations.


If the TX signal is clean on the main frequency I would be inclined not to worry even if there is a second decode at -27dB say 100hz up from the main signal at +15 dB”

The following stations provided reports of their two-way QSO’s and/or any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):

Tom, WB4JWM, completed a JT9 QSO with N4WLO in Alabama for a new state.  Tom also noted very high noise levels from storms in the southern US.

Bob, K9KFR, reported a JT9 QSO at 0052z with new station, N4WLO, in Alabama.  This was a new state for both stations.

Al, K2BLA, reported that he “Worked N4WLO on JT9 last night for a new station on 630m. Heard other stations calling CQ but lightning noise was brutal; worse this AM. A cold front from Texas up to southern states, and coming this way is very active according to Blitzortung. WSPR: heard by 45 only one over 3000 km. Heard 17, again only one over 3000 km. Only limited time xmting/rcving. Didn’t feel like battling the noise.”

Ken, K5DNL, reported his best session of WSPR trans-Atlantic reports ever while using 50 watts TPO.  He received reports from 96 stations including LA2XPA,  OR7T,  G0KTN,  DL4RAJ,  ON5KQ,  G0VQH,  EA8BFK, 2E0ILY,  G0MJI,  PA3ABK/2,  PA7EY,  F59705,  G0LUJ,  YV7MAE,  ZF1EJ and seven Canadian stations.  He reported seventeen stations.

Neil, W0YSE, operated WSQCall during the evening and provided the following activity summary:

“There was a little bit of WSQ activity last night on 477.1 (dial at 475.6) in the PNW. VE7CNF and VE7BDQ were in there as I recall.

I came into the shack around 10 PM and found that WSQcall had locked up (i.e. that “Windows needs to close” message on screen) so I had to restart it. The same thing happened to Toby VE7CNF about that same time.

After restarting it I decoded John VE7BDQ’s sounder message “away from keyboard” after which Laurence posted on KST that he wondered “whose away from the keyboard 🙂 wsq ”. Nice to see John’s WSQ was decoded in AK. Right after that Laurence decoded most of my sounder message also.

I continued to receive BDQ’s sounder messages periodically thru the night. I noticed that sometimes my sounder did not activate on every 10 minute interval as programmed. I believe it has to do with the strange movements of the squelch level setting, which I do not yet understand.

I pinged John and Toby and Roger’s machines this morning but got no response. I will continue with WSQcall again, sunset to sunrise (unless requested for daytime testing) on 475.6 dial (477.1 RF). Hopefully I will hear KC3OL soon. Not sure if anyone else is hearing us from back east.”

Ted, KC3OL, was active on WSQCall last night as well, receiving reports from SWL-EN61 located in Indiana: “KC3OL:f1swl de kc3ol”

Roger, VE7VV, reported many JT9 CQ’s from NO3M who was looking for stations in the Northwest.  Roger indicated that Eric’s best  transmission was at -18 dB S/N, occurring while he was not at the operating position.
