Om den här sidan av min blogg

Jag är radioamatör - om tiden tillåter. Än är jag inte särskilt aktiv och har nyligen skaffat en liten station som jag hoppas skall visa sig vara en lösning för en tight budget. Målet är HF, inte UHF och det som hägrar är DX med QRP.
Lite av bloggen kommer att vara på svenska och annat kommer att vara på någon sorts engelska.

Äntligen fungerar antennen

Har haft lite strul med en multibandsantenn, men nu fungerar den :-)

Handsome QRP

FT-817NDPosted by Jan Sun, October 20, 2013 21:19:13
I started my career as a radio amateur (TX) with a Yeasu FT817ND. I looked around quite a bit before deciding what to get. My goal was to work mainly on 40m & 20m. If possible it would be nice with other bands as well. SSB will most likely be my game, not CW. Telegraphy could otherwise be quite thrilling when experimenting with extreme DX & QRP, but CW simply isn't my cup of tea. Perhaps I will try PSK when I get the system up and running.
So far I have a vertical multi-band portable antenna. It is tunable from 80m down to 70cm. A portable 1/2 wave dipol for 40m is also in the backpack and of course the necessary 12V motor cycle battery to get the full 5W power of the rig. Without the extra power source I will only get 2.5W

Training

HAMPosted by Jan Sjöholm Sun, August 04, 2013 18:27:10
Basic training and examination for my HAM-license I got trough Nordvästra Skånes Radioamatörer (http://www.sk7dd.se) during the spring of 2013.
It is a nice little club i the south of Sweden that among other things run a repeater well situated in the area. Their HTTP is only in Swedish as are most of it's members.
A thing that I realized when I entered the club was that half of the students was sailors, planning for longer journeys. VHF on their crafts only reaches the horizon. They needed HAM licences to run their shortwave radio as we can't see from here to New Zealand... Interesting.

I didn't enter the training to a HAM empty handed. Lucky for me as I have lost a lot of patient required for studies. During the 1960's I was trained as a radio/television repair technician. Vaccum tubes was still in use, but semiconductors had entered the stage. Even the first primitive integrated circuits had pooped up, but we had to start from scratch by building electronic devices the hard way. We built amplifiers and power supplies from scratch, calculated the transformers and inductors and made them our selves. We studied the electronics very thoroughly from the bottom and up. A few years later the educational system had changed dramatically. I know. As a teacher in exactly the same subjects during the mid 1970's I faced a quite different situation. Education was cut by one year and the contents was very different. I could say that the education had degraded, but that would only be a part of the truth. It had been more adapted to the new demands on electronic technicians. Gone was the vacuum tubes and most of the radio stuff. The service and repair men of radio and television was already put in the shadow as the electronics evolved at a very high speed.
When I started my training I wasn't very worried about the electronics’s, it was the procedures and the legal stuff that had held me back. Another thing: during the 1960's CW was mandatory and I didn't have the ear for it. Period. Now, many years later things have changed. No CW and I am closing in on retirement and need a hobby :-)

You have my call sign and perhaps we meet on 40m QRP 7.090MHz





New call-sign

HAMPosted by Jan Sjöholm Fri, May 10, 2013 21:38:47
I finally got my call sign. Snailmail is ok, but the waiting had shortened my nails...
Next step will be to find a rig. I am looking for a HF rig that allows me on a tight budget experiment with QRP on HF; 40 metre or 20metre. I intend to run SSB, not CW.
