Interesting signal reports from my mobile setup

Yesterday, at lunchtime, I decided to test out the HF setup in the car, which I have recently reinstalled. I gave out a CQ on 14.005 with 100 watts through my roof-mounted Watson Multi-ranger antenna. I didn't actually want to make any contacts. I was happy enough just to look at the signal reports on the Reverse Beacon Network. And that's when it got really interesting!

As you can see from the photo on right, I was parked against a wall with a fence on it, and behind that is a big factory unit that it perhaps 30 feet tall. The front of my car is facing roughly east-southeast, so the factory is pretty much blocking me to the west-northwest. And what was my best signal report on the Reverse Beacon Network? VE2WU in Canada, which is where my signal should have been worst. Perhaps the fence was reflecting my signal strongly onto the long path? I had good reports from Belgium and Germany too, which should not be so surprising. But 54 dB snr from Canada is a damn good report, the sort of thing I mightn't even see with my hexbeam and 400 watts pointing directly to Canada!

Perhaps one of my readers can shed some light on what might have made my signal to Canada so strong?

Video - 5N7M in Nigeria audible on my mobile set-up

This is a short video of Ivan, 5N7M, calling out on 20m SSB, and audible on my mobile set-up, which consists of an Icom IC-706 MkII and a Watson Multiranger antenna.

My first mobile HF contact into Japan!

I decided to do a bit of mobile HF operation today, taking advantage of the fine day that it was, and giving the kids an opportunity to have a run around the place! I went to Bellewstown, a hill about five miles south of my home town of Drogheda. I brought the Icom IC-746 which has an internal ATU, and used just the Watson Multi-Ranger whip as the antenna.

Running 100 watts only, I was able to pick up some strong European stations, and then a couple a little further afield, in Russia. I was calling CQ on 18.153 USB. Suddenly I could hear a strong Japanese station calling me. He was JH0JDV, Ely San in Ojiya city. He was a decent 59 signal, sounding strong, with very little in the way of QSB.

We had a chat for a few minutes, and he was able to copy everything I said. I had thought perhaps the conditions weren't great, but this contact proved me wrong. Of course, Ely has a big station with nice antennas, so his signal would be good anyway!

It was an enjoyable hour. I brought the CW key but didn't do any morse. I wanted to see how well I would get out on phone, and was happy enough with my first mobile (phone/SSB) contact into Japan. Note: I had previously worked JA on 17m CW from the car!!

This is me on Bellewstown Hill. Note the Watson whip on the roof.
eQSL confirmation of our QSO !
