As our sunsets start to come earlier and dawn arrives later and later, the sun's accelerated southerly excursion has brought sudden changes to 630m propagation.





This past weekend's CLE activity saw universally poor propagation as well as weather related QRN from lightning ... but as usual at this time of the year, things can change rapidly. Wednesday's overnight map of my own 630m WSPR activity illustrates why September propagation on LF and MF can often be spectacular and this is with just 65 watts total power output:

Among other things, the map indicates the growing interest among U.S. amateurs in the 630m band. Hopefully they won't have to wait too much longer, although I seem to be saying this more often than I would like to. It is of interest to note that even though these were WSPR reports, signal levels at most reporting stations were either into the 'audible CW' levels or at 'JT9 workable' levels ... all stations should be workable once the 630m ham band becomes a reality for all North Americans. Midwinter conditions over the next several years should see an abundance of transcontinental contacts on both CW and on JT9!

The east-west path is the bread and butter direction for interesting possibilities, when it comes to those of us in VE7 land. Normally it only really sets in when geomagnetic conditions are quiet but, as a result of coronal hole streaming, this week's geomagnetic field has been anything but quiet. As John Langridge, KB5NJD / WG2XIQ reported today in his invaluable '630m daily reports':

The geomagnetic field was extremely active, with many reporting periods at storm levels. The Bz is pointing to the South and solar wind velocities are very high, peaking at 700 km/s. This event is significant and I am just glad to see that it is helping and not hurting propagation. When will the bottom drop out? Clearly there is a lot going on here that we do not understand.

With stormy conditions continuing throughout the week, Friday's path to down-under enjoyed some enhancement as well, not unusual when the east-west path is disturbed. VK4YB's 90 watt signal was widely heard by several VE7's (VE7CNF, VA7MM and VE7BDQ) in the predawn hour, as Roger's signal peaked up briefly for several WSPR decodes.

As the coronal hole streaming continues, this morning's path to VK seemed even better along with a new antenna at VK4YB favoring the northwest:

11:22      VK4YB      0.475614      -28    VA7MM      11872 km     
11:04      VK4YB      0.475614      -28    VA7MM      11872 km     
11:02      VK4YB      0.475615      -33    VA7MM      11872 km     
10:54      VK4YB      0.475615      -26    VA7MM      11872 km

I should mention that the other VE7 stations are all operating from noisy suburbs near Vancouver ... clearly fine examples of what can be done on 630m under less than ideal operating conditions and by paying close attention to system optimization. Please don't let living in the city stop you from enjoying the mysteries and challenges that our latest ham band has to offer ... as mentioned earlier, there is still much to be learned about using this band at amateur radio power levels and small backyard antennas. How exciting is that!

It was another amazing day weather wise up this way and with winter soon coming I wanted to hit the trail again with the KX3. I was up and out around 10 am local time and off to search out on my bike a nice spot on the lake to operate. (Lake Ontario) The spot I found was right at the lake and I could see the police boats setting up their perimeter for the air show that would be happening around noon. I planned to be done my portable op's before the air show starts, the noise of the low flying jets (which is a very cool sound by the way) drowns out my CW coping skills. I set my endfed antenna in a sloper configuration as I found the inverted V was just not doing the trick. The CW open contest was in full swing and that sure was a bonus for making contacts. I checkout the Contest rules and they were looking for a serial number and name. I was able to make 8 contacts in the contest:
N4OX on 20m from FL
AF4RK on 20m from FL
K5WK on 20m from MS
N6ER on 20m from CA
KZ5D on 20m from LA
N5XZ on 20m from TX
W9ILY on 40m from IL
AA3B on 40m from PA
N8BJQ on 40m from OH
I found the contacts on 40m were no repeat backs and all the info was conveyed on the first try. As for 20m I was asked for repeats on my call, name and serial by most if not all the contacts. I raise the output of the KX3 to 10 watts and the external power supply seemed to handle it just fine.

The park setup

With the fall fast approaching which signals colder weather that is just around the corner and with that an end to outdoor op's for another year I decided to get outside today. It's a long weekend up this way with Monday being a holiday. I decided to use up some of my time off and took Thursday, Friday and Tuesday off as well. I went to our local park this afternoon and with it being a work day I did not find it too busy there I was able to get a nice spot under a shady willow tree. My first setup was an inverted "V" configuration. I was out last weekend and used the same configuration and was not spotted anywhere on 20m or 40m. I was reading this week that it's best to setup the inverted "V" with an angle greater than 90 degrees. I was not sure if that was my issue last weekend  but I decided to try again today but making sure my angle was greater than 90 degrees. I ended up having the same results with no spots. I then changed it up to a sloper configuration and I was able to contact K8DSS from Florida on 20m. Ed gave my 5 watt signal a 539 and I was happy with that but for the day that was all I had time for. It was soon time to pack things up and head home. While in a QSO with Ed his CW signal was in competition with practicing air show jets ( CF-18's and FA-18's) and the jets were

New power config

winning!  During the summer I have had on to many occasions battery issues. I have had AA cells in the KX3 not last more than a 1/2 even after a full charge. I have a Tracer lithium Polymer power pack that is an 8Ah pack. I decided to purchase the same item again and parallel the two 8Ah packs. This gives me a solid 16Ah's of power and a nice steady 12 volts. I have been using this arrangement for the summer and am very pleased with the performance.
