As electronics Engineer I am retired after January 2014. In my professional opus I worked on research projects within the company Sipronika http://www.sipronika.si/about-company/about-us-en
Here is a link with all my contributions: http://www.worldcat.org/identities/np-jarc,%20janez$1949
In my spare time I also do some construction projects. Please find enclosed a brief description of my articles for radio-amateurs. They have been published in the Journal of the Association of Radio Amateurs of Slovenia CQ ZRS http://www.hamradio.si/index.php?option=com_content&view=category&id=22&Itemid=41 in the Slovenian language.
Capacitive band filter with MAX 295 circuit and its integration into IC202S and IC 402 . ( CQ ZRS June 2000, pages31-32 )
The paper describes a built-in IC 202S and IC 402 capacitive filter MAX 295. IC 202 S is an older 2m SSB / CW transceiver with originally built-in only 2,4kHz SSB filter. To work on the CW I made a simple and effective 1kHz SCAF filter. Please find the original article attached in the link below.
SSB signal processing methods and HF clipper for IC 202 (IC 402). (CQ ZRS February 2000,pages36-41 )
The paper describes physical basics of signal processing and how to optimally increase the mean power on SSB. On the VHF and UHF small power of 2W (IC 202 and IC 402) is used for portable work. In order to improve my QRP stations on SSB, I installed VF clipper in both QRP transceivers for increasing the mean power. Please find the article in the provided link below.
40m shortened rotatable " V " dipole S53V made from fishing-rods. (CQ ZRS September 2012)
This paper describes an implementation of a " V " Dipole, which is very simple to construct. Its radiation diagrams and DX characteristics are on the same height better than the horizontal Dipole or Inverted V antenna. The article is attached in the link below
Advantages of the "V" dipole against a horizontal dipole at the same height:
Capacitive filter with a 8W low distortion audio amplifier build in FT 2000 speaker FP 2000. (CQ ZRS December 2012) pages 18-22
SCAF ( Switched -Capacitor-Audio-Filter )
The paper describes in FT 2000 speaker (FP 2000) build an excellent audio filter. Capacitive filter integrated circuits MAX 267 and Max 295 are used. Besides, some physical and biological properties of hearing are described. Additionally an automatic gain control (AGC) to adjust input levels and 8W low distortion audio amplifier is added to SCAF the filter. The original article (in Slovenian leanguage) is attached in the link below.
