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.

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.
