Video: chasing Tuvalu on 20 metres CW. Will I be able to make it through the European QRM?


This is what I do most of the time on amateur radio - I chase rare DX. In this case, it's T2GC on Tuvalu island, which is an island in the southern Pacific Ocean. As you can see, it's hard work finding where he is listening, and in this case his RX QRG is moving all the time. So I have to spend a lot of time spinning the VFO looking for his split frequency. I lose the split though, and have to go searching for it. Having not found it, I decide to call above the pile-up (at 2:40 in the video), but hear a K2 beneath me going back to him, so I spin down to 14.013.5 and call him there. Soon I am back on target. At 3:56, you finally hear him asking for EI2. I call a couple of times, but he still comes back with EI2, the best indication possible that other stations are just calling over the top of me, ignoring the fact that he is looking for EI2. But with a bit of persistence I am soon in the log. This one took just over four minutes, but I have been known to spend an hour (and more) chasing the rare ones.

A very nice new addition to the shack!


I have acquired a very nice new addition to the shack equipment in the form of a German-made Scheunemann Morsetasten dual paddle. And it's a real work of art. It's also lovely to use on the fingertips. Here is my first QSO on the new paddle - with JR3IIR, Hiro in Japan.

QRP portable on PSK31 - five watts and five QSOs!

The car at Red Mountain with the antenna on the roof.
This evening after work I finally got a chance to test my new portable set-up for real. Previously, I had only tested it in the main shack connected to my home antennas. But today I wanted to give it a REAL test. So I took the portable station in my car to a hill about two miles from where I live called Red Mountain, just overlooking Donore village in County Meath. I wanted to run five watts only on either digi modes or CW, running off a separate battery, not the car battery. I didn't know what to expect . . . or even if it would work properly, although having tested it at home I felt it would.

It took me a few minutes to get everything out of the box and connected up. Eventually I would like to make a proper "go box", but for now I have to connect all the leads and that's OK. It only took a few minutes. I was using the Watson Multi-Ranger antenna on the roof of the car. I decided to use PSK31 so I didn't bother connecting a mic to the radio, or indeed the K1EL keyer. All I had to do was connect the radio to the battery, the antenna to the ATU, and the Signalink to both the computer and the radio. Oh, and I used the new Icom CI-V interface so that HRD could read the frequency and mode from the rig.
Everything fit on the passenger seat. It was a little uncomfortable because
I had to turn sideways to operate, but it all worked very well.
With all that done, I tuned up and then started CQing on 14.070.85 using just five watts. I was chatting to a couple of the local guys on two metres also. After five minutes of Cqing there was nothing, so I was thinking I might change to CW, but all of a sudden a F5 station was calling me! So I successfully made a QSO with him. I finished, thinking how delighted I was to have successfully made a contact with five watts when a German station called me. I worked him too. Then an Italian called me and I logged him. In total, I worked five stations in half an hour. The last one was the best DX contact - into Ukraine.

It was great fun - and very rewarding. The location helped. The hill falls away steeply towards the east so there would be good take-off into Europe. I packed everything away into the EI2KC portable case with a smile on my face.

I'm hoping to do more portable work soon - perhaps with a couple of the local hams in tow. We could maybe bring a flask of tea and some sandwiches and biscuits and make a nice social event out of it too...

Just a couple of things I need to do for next time. I need to get better clamps or connectors to keep the power lead connected to the battery. I also need to get a shorter RJ45 cable to connect the Signalink to the rig - it's too long currently.

Trying to work Brazil on 20 metres with 10 watts. Will I make it?


Above is a video I made last night of my attempt to work PV8ADI in Brazil on 20 metres using just 10 watts. Will I make it through with my almost-QRP power? Or will I be just too weak for him to hear? Watch the video to find out.

Video: Working Colombia (HK1MW) on 17 metres CW

Above is a quick video showing me working HK1MW in Colombia on 17 metres CW. I was running 350 watts at the time via the Acom 1000 linear amplifier into my two-element SP7IDX hexbeam.

Reminiscing . . . video from my second day as a ham



I'm doing a wee bit of reminiscing today. I came across this video on YouTube from October 30th 2009, which was the day after I received my ham licence. Here I am having a chat with Harald DJ8RP in the Black Forest on 20 metres SSB. It's nice to look back at a record of the early days of the hobby for me.

E6GG Niue Island dxpedition on 20 metres


This is E6GG Niue Island on 20 metres CW. I worked them a few minutes previously on a tight split. It was a nice bit of lunchtime DX, after working D67GIA Comoros Island on 15 metres CW this morning.
