HG50MHZ


August 10 2011, Budapest
Haros Radio Club, HA5HRK
At midnight on August 14 2011 the Budapest television broadcasting transmitter will cease operation on VHF channel one. The termination of Broadcasting Band I transmissions after 54 years of  television broadcasting will be followed by four days of ham radio activity organized by Haros Radio Club, using the antenna system of the former TV transmitter.  This activity at the special event station HG50MHZ is a memorial event celebrating more than half a century’s operation and at the same time publicizes the closure of a broadcasting transmitter which is well known to the six metre amateur radio community.
The webpage of HG50MHZ http://www.hg50mhz.tv summarizes the 54 year history of Budapest channel one television broadcasting, the 6 years of HA activities on the six metre (50MHz) band and additionally provides details of the special event station. Channel one television broadcasts from Budapest are well known by radio amateurs all over the world and have in the past been widely used as a propagation indicator.
This period of amateur radio activity will allow two way communications facilitating actual amateur radio contacts utilizing the antenna system of the television transmitter. The web-site http://www.hg50mhz.tv will also broadcast a video and audio stream in real-time from the station’s operating position, thus everybody will be able to listen to how his or her transmission can be copied at the former television station. The chat and guestbook pages of the site also provide another means of communications amongst the interested amateur radio community.

The location of the station is at the Szechenyi-hill broadcast station of Antenna Hungaria (JN97II). Station operators are either employees of Antenna Hungaria who are licensed radio amateurs or are members of the Haros Radio Club. The planned modes of operation are: CW, SSB, FM and digital. Besides being available for normal tropospheric and sporadic E modes of propagation EME earth-moon-earth experiments are also planned at HG50MHZ.
