Experience with the FuncubeDongle

I have the FuncubeDongle for 3 weeks at home. In these 3 weeks I've listen several moments to different frequencies. All this with my GP 2M on the balcony.

Different signals on 2M, this morning for the first time downlink signals of the VO-52 satellite. In this orbit I heard UA9FFF.
Furthermore, some signals on 70cm, 119,050 (AM) aircraft and digital signals of the C2000 communication.
During the Es season it is intended to receive signals on 70MHz. For this band I plan to make a wire dipole.

(Radio)vlooienmarkt in Rosmalen

Afgelopen zaterdag een bezoek gebracht aan deze vlooienmarkt in Rosmalen.
Rond 09:15 waren wij hier en konden relatief dichtbij de ingang parkeren. Problemen zoals door andere gemeld hadden wij dan ook niet.

Het was weer een drukke markt waarbij het mij opvalt dat er steeds meer handel komt waarbij ik de relatie tot onze mooie hobby niet zie. Of is dit meer bedoeld om je partner tevreden te houden?

Ik had geen boodschappen lijst maar ben toch om 15:00 uur met wat spullen naar huis gegaan. De 2 getoonde boeken, de rechtse is 2de hands. Een 4Gb USB stick, verloop van SMA naar PL259 en een MP4 speler, deze is inderdaad voor mijn YL.

This is a local event, so I have written this article in Dutch.

Goodbye to the Kenwood TS700S

Last week I said goodbye, after almost 25 years, to my Kenwood TS700S, a allmode 2 meter transceiver.
In 1987 I bought this transceiver and made many ssb qso's via tropo, Es and Aurora. I made 1 cw qso via Aurora.
This was a period of several years that I was very active with 2 meter DX, until I got my B license in 1991. In the last period as PE1MDM and the beginning of the period as PB0ALS I was also active on the RS10/11 satellite. The TS700S was used for the uplink.
I made the most qso's with 12 watts from the bare transceiver. Later I had a small 30 watts amplifier.

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.

Lighthouses in Portugal

During our stay in the Algarve, Portugal, we saw some lighthouses.

"Farol da ponta da piedade"


The highlight was the lighthouse "Farol de S. Vicente". It was open to the public, a unique.

QSL received

a few days before my trip to Portugal, I was at the monthly meeting where I can bring and get the QSL.
There were a fair number of QSL's for me, including some remarkable.
There were QSL's of the QSO's with OK1AUZ and 8S0C. Both QSO's are made with my FT817 + ATX1080 antenna and 2.5 watts output. My setup was on the dinertable.

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 ......

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.

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!

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.
