QRV from the Field

Last Wednesday, the predictions for the weather where not so good and we decided to do this activity yesterday. We were lucky: sunshine and good temperatures.

The purpose of this event was to build up the portable mast and see if the additional support is good enough. At about 6 meters height, we made an extra point with 3 ropes. It looked good and solid but from this upper point of the mast was pretty crooked.





The idea is to make the support more higher to obtain a better stability.The upper part have Eric, (PE1FES) and I let down, there was now about 6 meters mast on. The mast was now stable, without curves. The suspension point for the variation of the G5RV/ZS6BKW (2 times 7.77 meters) is here by also lower.


In both situations, I made some qso's. On 20M a cw qso with I6WJB in Pescara. This was my first cw qso while I was standing, we forgot the seats.
On 40M, I made qso's with: F/PH2CV/P (cw), SP9KAT (ssb) and SP9WZS (cw).
TRX: FT817nd with internal battery + later a external battery. The output power was only 2.5 watts.

We have had a lot of fun!

QRP on 20M

This morning I setup my portable situation on the dining table. This means the FT817nd with internal battery and on the back of the transceiver the ATX-1080 antenna.

First it seemed very quiet on 20M but during the morning I heard a few signals. While I had other activities in the house, I leave the transceiver on 14.060. Suddenly I heard HB9DAX CQ'íng. After one reply Man(fred) came back for me. We made a nice qso, the transmit speed of Man(fred) was a little bit to high for me. So, I have to concentrate me more than normal.

When I removed my setup from the table I wanted to move in the telescope. This is always stiff and one of the thinner parts nodded. It can still be moved in and out but it is not pretty.

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.

As 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.
