6 meters & J-pole for 2 meters

Yesterday morning around 8:00 local time, I heard during my breakfast signals from the beacon I0JX/B on 6 meters. Unfortunately, no further action was heard and gone outdoors for other activities that day.

Today I borrowed a swr meter to see what the swr is of my homemade 2 meters J-pole antenna made of 300 Ohm ribbon cable. The swr was reasonable, 1:1.4.





The J-pole antenna hung in the doorway to the balcony.

I made a qso via the repeater of Amersfoort (PI3AMF) without problems, 5 watts output. The other station told me that the swr is improving by an RF choke. I got a phonecall and the qso was abruptly ended. Google gave me no answer for an RF choke for this situation. Any ideas?

6 meter antenna

It's almost a week ago since I put my last post on this blog. This means that there was't to much time for the radio hobby.

Last week there was a chance of Aurora Borealis by an eruption on the sun. Unfortunately, the Aurora was to weak for me in JO21RV to hear signals on 6 meters via this propagation.








The antenna for 6 meters has not stood on the balcony for a few weeks. This antenna is a 5/8 wave for 2 meters. With a piece of extended it's now a fourth wave for 6 meters. The extension has now made a final.
This year I made a lot of qso's via Es with this antenna.




Thanks to Eric, PE1FES, for the mechanical work.

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.

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.
