Joataman Webpages

A Collection of Interests, Activities and Projects


Overview

Joataman is a general web site collecting many interests and hobbies (too many really...) into one space. Over the years I have dabbled in a number of areas of interest - narrowband communications, earth mode communication, telluric currents, antenna modelling and lately, amateur radio astronomy.

My technical background is the field of Electronic Engineering (mostly in Medical Electronics) and I hold a Degree in Electrical Engineering, Diploma in Electronic Engineering and a Diploma in Technical Teaching. I also hold Advanced Grade (VK2XV/VK2ZTO) and Standard Grade (VK2PSR) Amateur Radio Licences.  I am a qualified Six-Sigma Green Belt.

I am the inventor of the "Incremental Frequency Keying" (IFK) mode as part of my narrowband experiments. The IFK technique that I first described has been implemented by other parties in the software programs JASON, DominoEX and Throb. (see 'Narrowband Comms' for more details)

My personal interest in radio centres on ham radio, narrowband modes, small antennas and antenna modelling.

My current interest is in the field of Amateur Radio Astronomy - in particular the detection of pulsars with minimal equipment.

The amount of material needed to describe such activity warranted a separate sub-domain.  To see details of the challenges and successes in amateur pulsar detection have a look at the Neutron Star Group website (which I maintain).

Recently I have been successful in detecting the Vela Pulsar (May 2017). Details of that project can be found here.
