WSPR & Homebrew

From Friday night my FT950 was running with WSPR on 40M. Given the results, I think that the conditions are not so good.
My 5 watts signal is heard by 4X1RF several times, a distance of over 3000km. 4X1RF was also my longest distance I received.

In 2 newsletters of the Benelux QRP Club is an article by Albert PA3EKN about an universal cw transmitter. The crystal, some capacitors and inductors are the determining factor for the hamband used.
Albert described this project in newsletter 64 and 96.In the junkbox I found the PCB of this project with the crystal 3.582 MHz, not very useful for QRP. I ordered crystals for different QRP frequencies, including 3.560 MHz, by Genesis Radio in Australia. This past week I have installed. The transmitter works for the first time very close to the desired frequency. With tuning C1, transmit frequency is 3.560 MHz.

To be continued ......

WSPR on 40M/30M

Yesterday I started with WSPR on 40M. This morning I saw that my laptop was restarted last night.
With my sleepy head I restart WSPR and don't saw that the program was on 30M. All received data is passed as spots on 30M, while 40M it should be. My apologies for this mistake!

Now it is restored.

QRV from Zuidlaren, JO33IC

Last weekend I was in Zuidlaren for a few days, JO33IC. On Friday I setup my station, FT817 + 10dB attenuator. And the 30M ZEPP on the topfloor and a few meters outside. With WSPR I used only 50mW.
I made also a few cw/qqb qso's on 30 and 40 meters.

WSPR on 30M

After a long time I'm qrv again on 30M with WSPR.

This time with my FT817nd with battery power and the ATX1080 antenna mounted on the back of the set. Mostly just listen, otherwise the battery is empty very soon.

Heritage Day

This weekend is Heritage Day in the Netherlands. This means that many old buildings opened to visit, for free.

Yesterday I was one of the volunteers at the lighthouse in Noordwijk. In the afternoon I made some cw qso's, with the call PG6N, on 20 and 40M. The rest of this afternoon I guided the visitors at the entrance.

At the end of this afternoon there was for me the ability to take some pictures of the lenses with lamp. During the NVV lighthouse day on April 10 of this year was this not good possible.

Thanks to the crew of PG6N.

My own fieldday ( PA3GNZ/P )


Yesterday I started installing the capacitors on the board of the "Sudden Limerick receiver" project. All capacitors (18) are mounted, now all components on the PCB.
The next step is to build the enclosure. The PCB with components is the bottom of the enclosure. When attaching the front and back, the connection to the antenna connector and dial must make. This also applies to the on/off switch and volume control.

The on/off switch, switches the powersupply between the print and the 9 volt battery.




During the field activities of August 15, we learned that it's beter to move the additional support from 6 tot 7 meters.
The additional support is now on 7 meters and the antenna is mounted on 9 meters. With these changes it's a strong construction. The mast is not crooked anymore.
Today, in the last 30 minutes of the fieldday contest, I made on 40M 8 QSO's: Czech Republic, England (4x), Denmark (2x) and Germany.
After the contest ended I responded to a CQ of GB4AC, on the Isle of Wight, and made a "normal" qso. On 20M I heard many Japanese in the AA contest, but unfortunately I could not work them with 2.5 watts. On 20M I worked one station in the AA contest, RA9AE. All qso's made with ssb.

My setup for this day:
Yaesu FT817nd,
2,5 watts, powered by car battery.
Antenna: modified G5RV.
ATU: homemade from a Howes kit.








Thanks to Eric, PE1FES, for support.

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.

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.

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.

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.
