QRP with Easter.

During Easter I visited my mother in the northern part of the Netherlands. In her house is a ZEPP for 30M hanging, on the topfloor. Normally I span the last few meters via the window to the end of the garden. This time I put the last few meters to the floor in the attic.

I brought my Q5 30M transmitter and wanted to see whether the signal would be heard by someone.
The next project is a switchbox to connect a seperate tx and rx to an antenna.
I gave a CQ several times on 10.116 MHz and saw that my signal was heard in Slovenia. A distance of almost 1000 km with about 250mW output. This experiment was successful.

Then I wanted to try my Rockmite 40M transceiver. On Easter Sunday there was a contest in HB9 and impossible for me to make a qso. After the contest, I made ​​a new attempt, without success.
Always difficult with a crystal that you can not move.
I had a few successful qso's with this trx made​​ in the past.

The back of my "Limerick sudden receiver"

On my camera I found some pictures that I've made in December 2010. These are some shots from the back of the Limerick Sudden receiver.

On the left is the on/off switch, underneath the chassis to the 9 volt battery to charge.
Originally there was an RCA chassis in the kit for the antenna connection. I replaced this with a BNC chassis.

2011 coming, programming my Yaesu FT7800

As regular readers may have noticed I was not actively in recent weeks. Busy with other things, including my study.

My "new" desktop computer has no serial connector anymore. The cables I have for my Yaesu FT817 and FT7800 are not directly used on this computer.
A serial-to-USB cable that I had did not solve this problem.
In the Far East I bought 2 new programming cables with a USB connector. After installing the driver, I could program my FT7800.

I wish everyone a good 2011 with: Health, happiness and fun with the things you do in your leisure time.

In 2011 you see me again with regular messages. This is a project for 2011.

Listening with the Limerick Sudden receiver (30M)

Among the other activities of this weekend, I listened to the "Limerick Sudden receiver". I had a wire antenna of no more than 5 meters. Despite this short length for this frequency signals were heard.
I heard Sweden, United Kingdom, Italy and Belarus (EW8O).

This last station had a way of qso's which seemed more like a contest. Something I think this is not needed on this band and in my eyes undesirable.

I felt again the early years, I started as a SWL (NL-9514).

QSL & Limerick Sudden receiver

Wednesday, December 8th, there was a local meeting where the ability is to get the QSL cards from the buro. Through other activities, I was not able to go. The cards are taken by an amateur friend and I received it today.
There were some nice QSL's from QSO's made with the ATX1080 antenna at home and from the field activity in Maurik, last summer.
The project "Sudden Limerick receiver" has stagnated for several months but now the receiver is ready.
Making the case was a precise job and fortunately, I had some help. The description for the casing to assemble seemed easier than practice.

I have a few minor details changed. The RCA chassis for the antenna changed into a BNC.



The connection of the print to the BNC, is made with RG174 coax.

Next week I will try to publish some listening experiences.

Limerick Sudden receiver

This weekend I continued with the "Sudden Limerick receiver" project. I do this in a leisurely pace and spend my free time also with other things.
So I have watched a DVD of Michael Pailin, "The circkel around". From the 3 DVD's in the box I have now seen 2 episodes of the first DVD.

Yesterday I soldered until all resistors were mounted. At that time, the 2 IC feet, 3 coils and resistors mounted on the PCB.

Today I have some capacitors soldered. When I soldered the rest of the capacitors all components on the PCB.

Limerick Sudden receiver & Magazines

This morning I began with the further building of the "Sudden Limerick receiver. Meanwhile, all (6) resistors soldered. It's tougher than I thought to get everything straight on the board. It will be my limited experience. Tomorrow publish a photo on the blog.

Yesterday, I received the Electron magazine of the VERON, the September issue. Today I received also the "Nieuwsbrief" of the Benelux Qrp Club. Both magazines are in Dutch.

So enough to read this weekend.

Visit to the Zoo.

The last 1,5 weeks I have nothing done with the radio hobby. After the experiments in the field, I filled my leisure time with other pursuits. My 2 meters transceiver was sometimes standby in the evening but made no qso's.

Last Saturday I was with my girlfriend in the Zoo of Arnhem.






For me it was more than 15 years ago that I had been here. The pictures are a little compilation. After buying a new charger + batteries, a few weeks ago, I can shoot longer with the same batteries.

Saturday, I'm going to spend time to the Limerick Sudden receiver project.

My homebrew corner.

This week I walked around in my house with my camera and came up with the idea of yet another new picture of my homebrew corner. This is the result. On the desk are the components of the Limerick Sudden receiver project I'm doing.

Limerick Sudden receiverAs the manual shows I started assembling the IC holders for the LM386 and NE612.



I haven't found more time in the past week for this project.

Wednesday afternoon I had a qso with SM3YQX/4. Lars Erik, 30 km west of the town Mora. He worked with 100W in a dipole, I with 2.5 W in the ATX-1080.

Good weekend all.

QSO on 20M & Limerick Sudden receiver

Today I have made a cw qso on 20M with HA8LTQ. It was a "normal" qso where we both could share our details, like: name, name of the town and the equipment we used. This was on my side the FT817nd with 2.5 watts and the ATX-1080 antenna on the back of the set mounted.

Today I prepare the sides of the print and enclosure for the Limerick Sudden receiver with a neat file. Next week I can start soldering, as there is time.

My activity of this day.

Today during the IOTA contest, I had the opportunity to try my ATX-1080 antenna on 15M. I'm getting a good swr with the following settings:
15M
10 segments of the telescope extended, counterpoise for 17M in use.

Then I made connections with: Poland, Sweden and the Czech Republic, unfortunately, no stations on an island. My conclusion is that this antenna on 15M will work. On 20M I worked 2 stations in Romania and Sweden, all with SSB and 2,5 Watts.

Today I did nothing with the Limerick Sudden receiver project. Yesterday I only snapped the front and back panels from the mainboard. Tomorrow I smooth the snapped edges with emery paper.

Limerick Sudden receiver

Limerick Sudden receiver PA3GNZYesterday 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.Limerick Sudden receiver PA3GNZThis 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.

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.
