My name is Zoltan Nemeth, I was born on May 28 of 1943. After finishing the elementary school I finished the Oil mining and Deep Drilling Technical highschool, then I studied radio-television mechanic profession and I worked as mechanic. Later I finished technical class at Tivadar Puskas Telecommunication school. In 1968 I got married, I have two sons, they both work with computers. As my parents told me I was 3-4 years old when I eagerly turned the radio receiver's tuner. Maybe it started at that age? In 1958 I got my hands on a Radiotechnics magazine, it was a milestone in my future, either I think of my hobby or work.

As it began...

Still in that year I passed the observer exam, and started to work with the callsign HA1-0215 then later HA1-704. As observer I was listening for radio amatuers working on shortwave. The technical side of HAMing was interesting for me, so I started to extend my knowledge by building a 0-V-2 radio receiver. I converted this later to a super system. In 1961 I passed the "A" exam and in 1962 I got the HA1ZH callsign.

The first QSO, 1962 May 26. OK3CCM 3,5MHz cw rst 599
In 1962 I started to work with a home built 10W telegraph, then later with a AM mode radio. The antenna I used was a VS1AA. One year later I passed the "B" exam, and this allowed me to work on every HAM bands. In 1963 the radio got smaller, although I extended the power to 50W. The antenna was the popular G5RV.

In 1963 the rig got smaller,

In 1966 with HA1ZF Janos Andel radio amateur we formed the radio club in Nagykanizsa, I became the administrator. The club owned the HA1KZH callsign, and I was responsible for the trasmitter for some years. The first radio was a home built one. The operator training started, and some of them later got their own authorization.

In 1968 I started to build an SSB transmitter with a 9MHz filter which was the base for the 5 band SSB transceiver I built later. Soon enough my antenna got extended on the higher bands 14-21-28MHz with a 2 element QUAD - also home built. I used a 3,5-7MHz a parallel dipol instead of the the multiband G5RV antenna.
The first SSB QSO, 1968 August 31. HA3NE 3,6MHz rs 59

5 band 100W TCRV and the first SSTV equipement.

From the QSL cards received after each connection, soon a it was possible to apply for some diploma, certification. I was attending more national and international contests, where I could collect a lot new DXCC district. In 1972 I won the second place on the HA national championship in SSB category. In the next years I was making less transmissions, but I was building more, since my interest turned to SSTV - Slow Scan Television. In the country I was within the first people who got "infected" with this new transmission mode, and ever since I am eagerly searching for releated technical features, and I am hunting for other stations. I started to work with a home built camera and monitor. I built and used the "mechanical camera" which was only called between us as "picture cutter".

The first SSTV QSO 1973. February 11. SM5CLW rsv 595

Long persistence CRT SSTV monitor

The pictures were black and white and timed 8 secs. The picture was displayed with a long persistence cathod ray tube monitor. Here you can see the finished cathod ray tube monitor, which was built with tubes. The screen was 8 cm wide, and the memory effect of the cathod ray tube was used to display the picture.

The monitor, top view

On the disassembled monitor the following parts can be seen: the "cannon" which gives the sufficient shield for the tube, the low and high voltage transformator, the power supply and the diverting and video stage position.

Camera with transistors

The camera was built using transistors, PCT 254 vidicon, home built coils and focual coil. The camera was able to take 8 sec pictures in black and white slow scan mode. Through the lens the vidicon's sign plate received the picture which had to be read by the sufficient row and picture sync. By mixing with the video sign we received the complet video picture.


The camera from the inside

The PCT 254 vidicon can be seen in the camera along with the home built diverting and focal coil. Also you can see the shielded video amplifier - on the lowered panel - the VCO circuit which always supplied the exact frequency for the output, in the ratio of B/W and the synchron signs.

In 1972 I had my home built tcrv 100W, the PA 2xGI30, 9MHz xtal filtered KF, partly with transistors and tubes. The monitors were used for SSTV and one for ZX Spectrum for the camera, for texts. The changes in technology brought new ideas to SSTV modes too. The "slow" systemed cameras were replaced by the sampling based cameras, and the receiver side monitors were replaced by the SSTV converters. The analog - digital converters were not only used for black and white, but for color pictures as well.

FSTV-SSTV converter by G3WCY and G4ENA.

Soon I built my first SSTV converter using transistors and integrated circuits, I used original plans and I extended them with my own ideas. At the end I was able to use it successfully in 8, 16, 32 B/W and 48, 96 sec color modes. The base of the converter was the fast-slow converter by G3WCY and G4ENA. In 1989 after the release of the ROBOT 1200 C SSTV, I built the LM 9000 C built by VK3LM. This converter was able to work in the following new modes: Martin and Scottie. The modes were programmed into an EPROM. With the use of this converter the exchanged pictures between the stations had a very good quality.

My home built LM 9000 C sstv converter

The converter used a 8031 microprocessor, high resolution, 256x240 pixel screen size, 262 144 colors. EPROM, G30QD V4.2. All SSTV modes could be used, it provided possiblity for text messages, and had memory. The memory was able to store 4 color or 8 B/W images. From a menu the following options could be choosen: default screen to tune, character generator, oscilloscope - which helped in the fine tuning for the sign - colorgrid generator, gray shades and soundgenerator. FSTV or external video input could be attached and image was converted to the choosen SSTV mode. Later I built an interface to my first PC - 286. With the use of a computer program images could be down and uploaded, and modified on computer.
More and more computer programs were developed, helped in using the various modes.

IVCA DX Contest 1987 #1 Worldwide

In 1973 I passed the "C" exam. In 1981 I won the second place at GARTG's SSTV contest on wordwide. In 1982 I received my first SSTV diploma, the german DSSD Nr.1.
In 1987 I reached the highest point in my radio amateur activity on the IVCA SSTV contest. I won the first place of the wordwide contest. The contest was held for the first time by the IVCA, at this point 324 stations worked from 47 countries. On this contest in 1988, 89, 90, 92, 94 I won the 3rd place, in 1993 the 4th.

24. SSTV Activity Contest #3.

In 1999 on the JASTA Japanese SSTV contest I won the 2nd place, in 2001 on the JASTA SSTV activity contest - which lasted 1 month in september - I won the 3rd place.
Currently I am using an FT-277B radio, with lots of self built extensions. I can say it is a home built radio. It is able to work on all the radio amateur bands, including the WARC bands. The antennas I use change much during the years. Mainly dipoles for 1.8-10.1 Mhz and the queen of the antennas a 2 element QUAD - home built - for 5 bands 14-28Mhz till 2007.Now my antennas are some dipols for 1,8-10,1MHz and vertical for 14-28 MHz. I enjoy to hunt for unique/interesting callsigns, my favourite mode is SSTV, but I also use the digital modes beside CW and SSB.

Some diplomas received in the last years:

5BDXCC, 5BWAZ + 30M + 17M + 12M WAZ, 5BWAC, CQ-DX CW Honor Roll, CQ-DX SSTV, CQ-DX Field (190) Mixed Honor Roll, USA-CA 500

I tried lots of ham computer programs. I used most of the released SSTV applications. Currently I am using beside the home built LM 9000 C SSTV converter the GEST 2, SCAN, HI-RES and the ROBOT HELPER applications, and also with an interface between the converter and the computer. I also use the following applications: MMSSTV, MMTTY, DIGIPAN.

In 2002 May 26 it is 40 years that I have made my first connection over the air. For this event I applied for the special HA40ZH callsign, which I use from 2002 April 26 to 2002 december 31. I try to be active over this time period, hoping to make contact with interesting stations.
