CQWW DX SSB 2013

By ve7wnk on October 28, 2013

It was a good year for 10 meters and 80 meters. From the BCIT ARC I made 514 contacts in a rather small amount of time.

Friday evening I headed to the station around 7/7:30 after finishing dinner and driving down there. On my way I listened via my phone to a local station (VE7GL, Dale) as he worked probably EVERY JA on the band. Once I got there, the first thing I did was spin up 10 meters and found wall to wall stations. By the time I had the N1MM software loaded the band had gone soggy as the grey line had long since passed.

I dropped down to 15 and made about 30 Q’s by hunting for mults and calling CQ a time or two. My CQ’ing was cut short by RF blowing up the computer and getting into everything. Well deserved tho, we are using a laptop as our main station. The RF issues continued as I jumped onto 20, then 40, and eventually 80. By 3AM I figured I should head out, and I made my way home.

The next morning I had plans with some co-workers to take our XYL’s to a pumpkin patch, but all I could think about was picking off rare DX on 10. By 14/1500 local I was back on air and went directly to 10. For the next 4 hours I hopped between 10, 15, and 20, mostly looking for mults. I took some time to call CQ, but found I did better when busting up pile ups. I did have a pretty good run on 28.501 (Giving plenty of room to the DXpedition on 28.490).

Don, VA7LNX came to the rescue, and brought in some toroids to deal with the RF leaking into the USB! Problem solved!

The station stayed empty Sunday as I didn’t get out of my warm bed until after 11 – I was burned out.

Here is my final score after just a few hours invested – maybe 10?

10 Meter Vertical Ground-plane Antenna

By ve7wnk on August 25, 2013

YouTube often runs in the background when I am on the computer. Every once in a while I stumble across antenna construction videos that make me go “well, that’s just too easy to not try”. Dave Taddock, KG0ZZ, has a series of YouTube videos which talk about different ways to turn scrap into an antenna. One of these videos, the 10/11m ground plane antenna looked like a good one-day antenna build which would produce a great antenna for field operations.

The radiating element is ~8ft4in of aluminum tubing fed directly from an SO239 connector. Two pieces were used so that I could telescope it in order to tune it for different parts of the band. This was done by cutting teeth into one of the tube and adding a hose clamp to keep it taught. The ground, at least in my build, is 6 radials of the same length. The radiating element and the earth are separated by PVC. The mount is from the feed point of an old yagi which was scrapped by the Coquitlam club. For some reason I spared the unit on clean up date and it has now become useful.

The antenna photo, taken at dusk, can be seen below. I will provide better snaps shots later on, but for now, this should do.

I set the unit up and plugged in a radio before even tuning it. I spun the dial around and was a little bit disappointed. As for band conditions, there was not a peep on the band other than a beacon which was barely there. I rolled the VFO over to 20 meters and found it was hopping with activity – a good sign. The antenna was not cut for 20 so I didn’t bother trying to raise a contact at the risk of the finals. With the radio back on 10 meters and the power backed off I tuned around the band. It was about 1.5:1 on the majority of the band with a preference for the lower portion where it dropped until I hit the band edge. I slid the inner tube down a few inches to bring the SWR to 1.1:1 and the beacon came up enough to move the S-meter. I brought the power back up and tested transmitting – pop – the radio rebooted. Not enough power. Resolving to just RX for now I swept the band and found activity at 28.690. It soon became apparent they were holding a net, and taking check ins. These guys were all local to me, within 30kms, so most where loud. I tried to call on the next call but the radio dropped out again, I had to start the truck and try again. About 9 S-Units of ignition noise greeted me at the radio.

The video is not great, but it shows the noise, the net, and the antenna (sort of), and my legs…The radio is borrowed courtesy of the Coquitlam radio club.

Thank you for reading this! Cheers,

Bob, VE7WNK
