They were also involved in a DRM shortwave trial in Budapest two years ago; it covered for a year the entire city with music broadcasts.

As the company held a professional event, titled “SZOMEL Day” to promote their activities, they invited the key electronics and telecom entities in Hungary. Representatives of the National Media and Infocommunications Authority and Antenna Hungaria (the Hungarian public broadcast distribution company) also attended the event. (Antenna Hungaria also held a separate two-hour session).

During the event Szomel demonstrated a working DRM transmission chain explaining its key elements and measurements. They used an RF generator transmitting a DRM signal and recorded IQ samples of an Indian DRM music as well as a speech channel including the Journaline service (the advanced text feature of DRM). Szomel played it out in a loop with a R&S IQ modulation generator (AMIQ) connected to an IQ modulator (SMIQ). The frequency used was 26.06 MHz, the power 1 mW, sufficient to cover the conference room for this demonstration.

The Szomel event was considered very successful by almost the one hundred attendees.[/vc_column_text][image_slider_no_space height=”300″ highlight_active_image=”yes” images=”13220,13221,13222″][vc_column_text]Photo credits: Sara Ferencz, courtesy of SZOMEL Kft.[/vc_column_text][/vc_column][/vc_row]
