Note: If you access this page via my mirror server WWW.QSL.NET, it might be not up-to-date, since the access to that is not so easy for me. If you want to be shure to access the latest version, just forward to my primary server WWW.SCN.DE.

Notes:

• Green squares are confirmed, red ones unconfirmed, blue squares are unconfirmed since more than 2 years.
• Not included are outside the map range worked EME or MS squares
• I am of course very interested in any skeds, especially with already not confirmed squares.
• You can click on the maps to see them in an expanded view

• IMPORTANT! The missing cards table is not a black list! Its just if somebody knows how to help me to get these cards ok

Please check your databases or received QSLs if you can help me how to get these QSL cards.

50 MHz  (08.07.1998) (Due to my QTH in the restricted area of TV transmitter "Gruenten" 6m is very limited for me. I had an experiemental licence during the first time when 50MHz was legal in DL, but did not renew it for the further time due to that. I am currently waiting for the general opening, because my YL's QTH (JN58ri) is outside the restricted area

144 MHz  (21.12.1998) (This list is not a black list. But if you are or know somebody from the list, please help me to get the missing QSL card) 144 MHz missing QSL cards: sometimes squares are worked like this

432 MHz  (08.12.1998) (This list is not a black list. But if you are or know somebody from the list, please help me to get the missing QSL card) 432 MHz missing QSL cards:

1296 MHz  (08.07.1998) (This list is not a black list. But if you are or know somebody from the list, please help me to get the missing QSL card) 1296 MHz missing QSL cards:

2320 MHz (since 04.06.98) (08.07.1998) (This list is not a black list. But if you are or know somebody from the list, please help me to get the missing QSL card) 2320 MHz missing QSL cards:

 

North America on 70cm EME (21.12.1998) (Some blue squares mean that there are QSOs older than 2years which ware still not confirmed by a QSL card, even on EME)

JA on 70cm EME  (21.12.1998)

This is my RIG: (Nearly every equipment of my radio station is homemade)

Some samples from my QSOs

  "DXpedition" to Rosenheim, JN67bu

A special sample: Yet another way to do a QSO: DK2DB on 23cm (sorry, I lost the "DB"): (click on the pictures to get them in high resolution)
Subtitle: What is good for VLF, is also good for SHF... or... who says CW must always be at 60 lpm?
And... Yes, my 13cm transverter's frequency is instable...
 

His initial signal (the first "man made" signal on 13cm I ever received)

"DK2" on slow speed: each dit is 3sec long

My EME antenna is on a foldable mast. It is rised using my car. Watch for the rope wound around the trailer clutch.  By the way, on this picture from my balcony you can see my free view to North.

One time it happend that during a VHF contest the preamp relay broke. Since I need just 1 hour to change it, I decided to do so. While expanding the mast again, I pulled it too far, and so the whole mast fall down. Lucky, one of the two 70cm antennas was on the right, one of the left side of the power supply line on the other side of the roof.  The picture shows me and my sister, DG4MNI, dismounting all. I reassembled with a spare 21ele Tonna and was QRV just before night came and reached a 16th place.

I also like motorcycling with my BMW R80GS (built 1984), prefered in Italy. Mostly I also like to visit Lake Garda, but since then time when I am no alone for me time for these is very restricted.
Sometimes, I like to visit a long existing music hall close to me, Sommerkeller in Igling.
And I nearly always listen to that radio: N-Joy-Radio. Here in southern Germany, it is available on sattelite Astra only, so I can't receive it with the car radio.

Selbsterklärung gem. Vfg 306/97:
(This is in German only, since only DLs are considered about these items)
Nach einer Störmeldung meiner Nachbarn führte die RegTP Feldstärkemessungen durch und bat mich aufgrund der hohen Feldstärken meine Selbsterklärung sobald möglich abzugeben. Hier habe ich meine der Post gegenüber gemacht Erklärung im HTML- und PDF-Format veröffentlicht. Als weitere Literatur ist die cq-DL 2/98 und 3/98 empfehlenswert.

These are my current projects:

• FT847 test series
• FT847 external receiver input modification for 144MHz and 432MHz

• 23cm / 13cm Ring Feed good for dish antennas with f/D=0.4-0.5, and here with photos
• Elevation measuring using a Smarttool device
• A 70cm big wheel antenna  with description about building
• Feeding of yagi antennas for 2m, 70cm and higher
• Feeding a 6*33ele EME antenna system with parallel wire  (last updated 07.04.1999)
• A very simple meteosat reception antenna (maybe yet not present, so watch for it)
• GS35b 144MHz kw-Amplifier including my Weinheim '98 script
• GS35b 432MHz kW-Amplifier description see in 144MHz amplifier description
• 432MHz 150W 10dB transistor amp using a TP3069 transistor (maybe yet not present, so watch for it)
• 300W 3-150MHz solid state PA with 14dB gain using a single MRF141g power FET transistor
• 2 x 2x2C39 1296MHz Power Amplifier and the description how it is built
• PA control unit, handles heater startup delay, grid and plate voltage supervision, sequencer for PA and preamp and more
• Triode bias circuit for large and small triodes with disable/enable
• RF switching unit for any kind of power amplifier / receive preamplifier (VOX)
• GI7b 1296MHz 500W-Amplifier
• 70cm FM PA 2Win/100Wout with MGF1302-Preamp for Packet Radio use, working with the RF switching unit and an easy PA control unit
• Fool save 4 channel transmit/receive sequencer with Push/Pull-Outputs
• LED bar with 10 leds, used at the 300W 3-150MHz solid state PA and the 70cm FM PA
• Moon tracking unit with a 80C535 (similar to that of OE5JFL)
• PCB for a LA8AK audio up-converter
• PCB for a DJ9BV Wattmeter (single sided 11x10cm, not these expensive switches, with a MAX632 charge controller)
• planned: Light wattmeter circuit, derived from the DJ9BV Wattmeter , offers forward and reverse power measurement including SWR calculation with peak sampling for one channel to be used in any power amplifier
• planned: RF clipper, easy and simple, including a relay to switch it off
• Roger-Beep (simple add-on, needs no wires to be cut: senses PTT line and adds its beep when PTT goes inactive)
• Description of my antennas for 144MHz (PDF), 432MHz, 1296MHz and 2320MHz (PDF)

(Note: The PDF files were taken from the DUBUS archive ftp://dpmc.unige.ch/pub/dubus)

• Sources for the parts which I sometimes need for my projects

• OK1KIR 23cm PA with GI7b
• DL1VU 23cm 4*2C39 PA

DB0ZKA-8: PR-Mailbox in Augsburg:
For about 10 years I operated the Packet Radio Mailbox DB0KCP at my own shack. Then due to several facts I decided to shut it down locally and join it with my friend's digipeating system DB0ZKA in Augsburg, JN58ki. But I am currently still taking care on my baby, the mailbox PC and the SW operating there, although the PR access is not very easy since I gave up all  I had in that mode. (See: 70cm 100W power amp)

Here are some "official" notes when my pages were found interesting for publicity, which I am very glad to have them received.
