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

Very noisy night in North America impacting domestic activity on the eastern half of the continent; Better conditions in the West; Trans-Atlantic openings were better than trans-Pacific during this session

It was very noisy in North America last night presumably due to storms off of the East coast.  Storms were also present on the West coast near southern California.  Europe continues to be impacted by a major storm system  that has brought very high winds to parts of the continent.  The Pacific Rim has improved some but Japan continues to experience a few storms in the central portion of the country while Oceania has its own problems with large storm systems in northern and eastern Australia and much of the south island of New Zealand.

Geomagnetic conditions were quiet.  The Bz is pointing slightly to the North this morning and solar wind velocities are averaging near 360 km/s. DST values remain very stable and near the center line.

 

 

 

Propagation may have been much better than band conditions as noise was very high, resulting in low activity during this session.  There were some early openings reported prior to noise ramping-up to challenging levels in the East, however.  The West was a bit more hopeful with  QSO’s reported up and down the West coast.

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!):

Neil, W0YSE, reported that he is back to near full power and even completed a few JT9 QSO’s.  He submitted the following comments and statistics:

“As I started typing this I got a decode of Roger-VK4YB’s JT9 cq at -25 dB. I called him several times but no further trace of him. This happened around 1342z. I also had a WSPR decode of Roger about an hour earlier at -32 dB.

Last night I had 3 JT9 Q’s: VE7BDQ, VA7MM, and N6PIG/7.

Got my new MFJ-4218MV power supply online. It allows me to put out a cleaner signal (as far as I can tell at this point) at over 2 watts EIRP. I am now pushing my IRF540 amplifier at 6 amps input DC at ~20 volts, which seems to be ok so far.”

Al, K2BLA, reported high noise, resulting in no JT9 during this session.  Using WSPR, he reported, “…heard by 49 including EA8FBK, K9FD and YV7MAE in spite of what looks like moderate noise. Heard 16.

Ted, KC3OL, completed JT9 QSO’s with WB4JWM and VA7MM.

Mark, VA7MM, completed JT9 QSO’s with KL7L, N1VF and KC3OL.

Ken, K5DNL, reported that he operated WSPR through this session.  He reported twenty stations and he received reports from 83 unique stations including KL7L,  K9FD (/KH6), YV7MAE and  ZF1EJ.

Roger, VK4YB, operated a bit of JT9 this morning, receiving a report from W0YSE at -25 dB S/N at 1325z.  Roger added that he “…was calling CQ rather than DE because I could see a little blue in the waterfall, but very little chance of decoding.”

Keith, K0KE, reported in a previous session that he was going to perform additional low power tests after a PA failure forced him to lower power on January 1.  He submitted the following comments about last night’s low power test:

“Last night I decided to push the envelope on 630m WSPR a little farther.   Started out the evening running 5 mw and got quite a few decodes from VE6JY so later on dropped the power to 2mw and let it run overnight.   From 0500z on to 1430z I had 11 decodes at VE6JY running 2 mw.  Best decode was -26 at 1240z and last decode of -29 at 1408z.  Guess I will try tonite at 1mw!  I must pass kudos on to VE6JY as having by far the best ears of any receiving setup out there.  At the 2mw level I did not receive any decodes at any other station within 1000 miles, even the close in boys KC3OL and K5DNL  I did receive some ground wave decodes from W0AEW in northern Colorado abt 75 miles away.”

Activity at KB5NJD was brief.  I’ve been “under the weather” for a few days and after hearing the elevated noise I decided it probably wasn’t going to help my pounding head to listen so I didn’t spend much time on the air.  I heard K4EJQ calling CQ on CW about 45 minutes before my sunset at just audible levels and before shutting down after full dark, W0RW was calling CQ on CW on 474.5 kHz
