Limerick Sudden receiver

Yesterday I opened the envelope of this kit to verify that all components are in the packaging.





In the manual there is a list of components and I soon found out that all these components are present.This weekend I read the manual and make a plan how I going to start the building.
My idea is to make the wiring to the antenna connector with RG174 coax and not with the twisted wire which is written in the manual. For the antenna connector, I like to use a BNC chassis instead of a RCA chassis.

I'll keep you posted about this project.

Experiments with the ATX-1080 antenna

Last weekend I took the time to experiment with the ATX-1080 antenna. My expectations of this type of antennas have never been high. Now I have a somewhat different view.

In the limited manual of this antenna is discussed by making a counterpoise for them as possible to function. This manual is a guideline given for each band. After some soldering,cut and try, I came to the following lengths:
A counterpoise for 20M, length approximately 3.9M
A counterpoise for 17M, length approximately 3M
A counterpoise for 10M, length approximately 2M

30M
Almost 3 segments of the telescope extended, counterpoise for 20M in use.
20M
10 segments of the telescope extended, counterpoise for 20M in use.
17M
5 segments of the telescope extended, counterpoise for 17M in use.
12M
8 extended segments of the telescope, counterpoise for 10M in use.
10M
10 segments of the telescope extended, counterpoise for 10M in use.

During these experiments, I made a few QSO's:
9A2YM (20M cw)
OK1AUZ (20M cw)
UA1CE (20M cw)
SV2HJQ (20M ssb)
On the Friday before I made 2 QSO's with Lithuania on 30M.

At all QSO's I had an output of 2.5 Watts. My FT817nd was on the dining table (see) with rear mounted antenna. The counterpoise lying on the ground.

First qso with ATX-1080 antenna and 2,5 watts

Last week I bought a second hand ATX-1080 antenna for my FT817nd. Yesterday I received it by the mail and today I had the time to try this antenna.









With a cup of coffee I sat quietly at my diningroom table and listened to 20 meters, swr reasonable. I heard the special call SI9AM, this time with ON5RZ as a guest operator. A lot of stations called him and it seemed that he not heard my QRP signal. Nevertheless, my patience was rewarded. Raf said my call with an error and I answered to it. He corrected my call and we could made a nice QSO. Details of my setup passed and I told my name.

Who knows what for fun this antenna gives me even more.

Limerick Sudden receiver, by GQRP club

This week, no radio activities. The weather is too hot for hanging over the soldering iron and I am home with a painful ear infection.

By post was the latest Journal of the club GQRP 'Sprat'. A Magazine with always interesting articles. By this time the announcement of a kit what the GQRP club is sold. The Limerick Sudden Receiver.

Contest on 6 meter

Saturday afternoon, I was listening on 6M because there were conditions. I heard that there was a contest and on the internet I found out what kind of contest this was. I came to the following information. In this contest you change a report, serial number and locator.
Among the other activities, see previous posting, I have made a total of 20 QSO's.In this picture are the lines through the various contacts visible. Clearly the most possibilities were to eastern Europe. The farthest distance was with UU9A in KN64SM, over 2000km.
I made the qso's with cw/ssb and the most with 20 watts, 2 with 10 watts. From the 20 qso's there were also a few new squares: JM68, JN94, KN44, KN64, JO91 and KO14.
