I finally managed to record some video, with my Canon SX-230, of the Hi-Per Mite Active Audio CW Filter. I had to delay filming by a week due to sinusitis, but this turned out for the best since the WPX yielded enough signals to show what this filter can do. I am more than happy with it and it is going to be a permanent part of my set up. Thanks to Larry (W2LJ) for mentioning this great filter here on this site. The only thing left is to find a case to build it in. This coming Saturday we are going up north to Taipei, so ample opportunity to get one. Enjoy the video.

I’ve had a mechanically completed SatNOGS ground station sitting in my garage in need of some care and attention for a while. Its just one of the projects that that I have filed under ‘ working but not very robust’. Essentially after I killed off the first driver board we have not managed to get it to drive properly (that is without smoke pouring out of motor driver’s).

Fortunately the SatNOGS gang have made it much easier to load up the client software on a RPi and run a rotator free ground station on the development site. So over the weekend I have produced a standalone set up in between going to the 2nd harmonics rugby festival under the moniker Ground Station 170

The set up is very simple get yourself a RPi 3, an rtl-sdr dongle and a simple antenna (I used this one which took all of 10 minutes to make) and have scheduled a few passes to see if it works. There is some info here if you’d like to have a go

If you have a few moments you can look at the other SatNOGS stuff such as the recently presented video.

Dave, WW2R/5 reports that the WX9XRU 70MHz beacon in Virginia was activated on Saturday afternoon, 26th May. The beacon is beamed across the Atlantic, so hopefully there will be many reports from Europe this summer.

Dave heard the beacon, by Es off the back of its’ beam on Sunday on his 70MHz dipole over a distance of 1626km.

I don’t normally operate the WPX contests, but several friends (e.g., KB9UWU and SM2WMV/SJ2W) were planning efforts and I thought it would be worthwhile to spend some time working them.  The high bands have been in good shape lately.  And, WPX CW was the first CW contest I ever operated (in 1997…my call was AA8UP then if you want to look up my stellar performance).  Why not have a little fun?!

The 30-meter open-wire fed dipole at 40 feet worked great as two half-waves in-phase on 15 meters into Europe (and the Pacific).  Now, I can move the lackluster 15-meter dipole high into the back tree for N/S operation.  In fact, it might actually be smart to just put a second 30-meter open-wire fed dipole there.  Interesting thought.  Probably have the parts to build another tuner in the junkbox(es).

I paid basically no attention to strategy and just did whatever I pleased working interesting stuff and running a little bit later on.  I didn’t spend much time on 40 and I didn’t work the 2nd radio very hard until the last 1.5 hours between 2114 and 2249 on Sunday when I made 124 QSOs…not big rates, but a nice pace for using the second radio to fill in dead space.  Here is the damage:

“Sleep when the baby sleeps,” new parents are told.  All six hours of operating were with Evan asleep and about four were with Sarah asleep.  So, guess who’s behind now!

I’m exhausted, so I’m going to make this quick. It’s been a full day! Today our dear friend Rachel got married to Wayne, a fine fellow, in the chapel of Wycliffe College at the University of Toronto. That of course was the highlight of the day, but what is of most interest on this blog is how ham radio played a small part.

Our good friends, the Marshalls, are staying at the same hotel as we are. Since roaming charges are so high up here in Canada, we all have our cell phones turned off. But two of the Marshalls are hams, and they also brought along an HT. Here is a picture of Brent Marshall, K4EMC, and his son John Marshall, KI4JQB, standing with me at the end of the day’s festivities.

Before splitting up this morning, we agreed upon a simplex frequency and a repeater: the one at the top of the CN tower, VE3TWR. My wife and I went on to Wycliffe College while the Marshalls took in the town for a couple of hours. Thanks to our HT’s we stayed connected, and it’s good that we did. I radioed a subway route to them and, more importantly, passed a couple of messages back and forth between the mother of the bride and Mrs. Marshall, upon whom the harried mother was relying for help. When we were too far apart to use simplex, we used the tower repeater.

Nowadays we rely upon our cellphones so much that we forget sometimes how useful these radios can be. I brought my HT along on this trip for entertainment, but today it came in mighty handy.

The action on 20m early in the evening

It's Saturday night and the bands sure are busy BUT it seems not with to many new DXCC's for me. I have picked up about 6 news ones since the contest began. I have decided to also drop my power down and try to contact the countries I already have DXCC's for. Up to this point I am at 100mW's and getting into Europe....mind you with repeats. I hope to pick up a few more DXCC's on Sunday but now it's time to relax!!

Happy Memorial Day!

Although officially, Memorial Day will fall later this week, it will be observed this Monday.  So in the US, this weekend is always called “The Unofficial Start to Summer”.

There will be parades, B-B-Qs, parties, shore getaways, lake getaways, family gatherings, picnics, notable radio contests, etc, etc, etc.

No matter how you are spending your weekend, please be safe and have a very good time.  But somewhere during that good time, please take a moment to remember and pray for all those who made the ultimate sacrifice for our Nation, during all the conflicts that we have faced.  That is what this holiday is all about.

Freedom is not free and we honor those who have paid the debt for us.
