Radio: it's not just a hobby, it's a way of life

Typical Operating Schedule

Usually QRV CW most evenings, tuning between 472.5 kHz and 475 kHz with CQ's on or near 474.5 kHz. Occasionally QRV JT9, 474.2 kHz dial + 1000 - 1350 Hz. QRV some mornings starting around 1100z on CW. Sked requests are welcome. All activity is noise and WX permitting

A very slow start with deep QSB ultimately turned into a pretty good session of domestic and transcontinental openings late in the evening; Trans-Atlantic openings are better but trans-Pacific openings are down considerably

The south central US experienced a number of big storms containing lightning through the evening, overnight and morning.  Remarkably it was a relatively quiet evening.  The western Pacific remains active from Japan to Oceania where the Australia was bisected from Southeast to Northwest with strong storms .  The population centers in the Northeast and Southwest were clear but VK4YB in Brisbane reports extreme noise.

Geomagnetic conditions were quiet.  The Bz is pointing to the North this morning and solar wind velocities are averaging near 584 km/s.  DST values are relatively stable and remain near the centerline at negative levels.




Propagation was once again poor in the early evening with strong QSB but reports suggest that the band turned around by late evening, allowing a number of QSO’s in spite of the QSB.  Subsequently, it was a pretty good session overall.

Reverse beacon network reports follow:


David, G0MRF, is deploying his portable station today, located in “IO91FR  which is between the towns of Oxford and Swindon“.  His operation will begin today and continue  into 2018 or whenever the antenna falls down.  Look for him on JT9 and stay tuned for more information and images.

A few comments about the MF and LF chat situation:  Please use the chat tool that best meets your needs.  You are under no obligation to use the new system and no one ever has been.    The “new” tool was created in response to a number of reports that disruptions in the ON4KST chat were having a negative impact on the practice of good radio.  Probably fifty to sixty access requests have been received and granted thus far and access is open to just about anyone who asks for it.

This is a very different chat environment and as I stated in a recent post on the 600-meter research group, its really not a passive tool.  There is no history and if there is any loss of connectivity or a ping from the server is not acknowledged quickly enough, your connection will be terminated and you will have log in again.  I realize that it is not a perfect system.  As far as I am concerned, I don’t really need a chat to do good radio and I think all of us can share that sentiment to one degree or another.  It can be a nice luxury to have, however, while evaluating band conditions or arranging QSO attempts.

Jim, W5EST, submitted the following screen capture of his WSJTx console showing JT9 activity observed at his station in Little Rock, Arkansas (click to enlarge):







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!):

Larry, W7IUV, reported a poor start to the session, only completing a JT9 QSO with W0YSE.  Later in the evening, the band opened a bit, allowing transcontinental JT9 QSO’s with KC4SIT and K5DOG.

Frank, W3LPL, reported improving propagation with more activity and less noise than previous sessions in Maryland.  He completed JT9 QSO’s with WB4JWM ,  KC4SIT and  K5DNL.  Using WSPR, Frank shared two-way reports with K9FD (/KH6).

Terry, W8ARE, reported a JT9 QSO with W8RUT and indicated that he now has ten states, seven of which have been confirmed with LoTW, using only a 19-foot-tall antenna and JT9.

Ken, K5DNL, completed JT9 QSO’s with ZF1EJ, NU6O, WB4JWM, W0YSE, N1VF and W3LPL.  Using WSPR overnight, Ken received reports from 97 unique stations including LA2XPA, K9FD, ZF1EJ and ten Canadian stations using just 48-watts TPO.

Tom, WB4JWM, reported JT9 QSO’s with K9KFR and ZF1EJ.

Neil, W0YSE, reported that “Last evening I had JT9 Q’s with these 6 stations: W7IUV, K0KE, KA7OEI, VE7SL, NU6O, and K5DNL.

…and, I heard these 9: AH6EZ, K4SV, K5DNL, K9FD, KR6LA, N1VF, NU6O, W8RUT, and one decode of ZF1EJ at -28.”

Neil added later that K9MRI and others reported his JT9 signal that he was not aware of.  He submitted the following PSKReporter display (click to enlarge):

Roger, VK4YB, reported “Poor TP propagation tonight. Usual heavy QRM. Not hearing anyone, not even VK. There is a narrow corridor to Alaska with just a few weak spots elsewhere.

Robert, KR7O, reported “Solid daytime reception of W7IUV yesterday throughout the day.  JT9 QSO activity very busy last night with 12 stations copied including KC4SIT, K9MRI and K9KFR.  18 stations copied on WSPR including TC to K4SV (50/-16), KC4SIT (23/-21), WD8DAS (-28), W8RUT (19/-15), K4LY (10/-21).  Also copied new station K1YQP in CM98 with 50mW.


ZF1EJ 2 spots, -24

K9FD 106 spots, -7 (signals down a bit from normal)
