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.

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.

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.

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.
