The JOTRON equipment TR-7700VU Sol-Air Multichannel V/UHF AM multichannel dual-band radio is a unique and monolithic equipment of 3U 19" dimension without any additional elements associated to the outside of its structure, it has 3 connection possibilities for the head elements and internally has an antenna die-casting in compliance with the specifications, finally it complies with the highest Aeronautical Standards of the EUROCAE ED137 B&C, ICAO Annex 10, Implementing Regulation (EU) No. 1079/2012, EUROCONTROL and ETSI regulations
The JOTRON equipment TR-7700 VU has an integrated test system, Climax Mode and works with SNMP V3/V4 protocol. It has a nominal output power of 50 watts in VHF and 30 watts in UHF (up to 50 watts as an option) that can be set in steps of 0.1 dB from 1 watt to the maximum nominal power of 50 watts for VHF and 30 watts for UHF.
Among others, this ground-to-air radio equipment is a V/UHF AM multi-channel dual-band operating on the very high frequency aeronautical band. VHF (civilian from 117.975 to 137MHz and extended to 144MHz to include the military VHF frequency or finally (138MHz to 144MHz) and also on the band UHF (225 MHz to 400 MHz).
In other words, the V/UHF equipment operates in amplitude modulation, in simplex mode, in the VHF frequency range from 118 to 144 MHz in steps of 25 KHz, 12.5 KHz and 8.33 KHz (civil and military) and in the UHF band 225 to 400 MHzin steps of 25 KHz, 12.5 KHz and 8.3 KHz in UHF.
In accordance with Annex 10 of the ICAO recommendations, the frequency step and associated bandwidth parameters are automatically determined by the displayed frequency valueSo, for voice, the JOTRON equipment TR-7700VU operates in three operating modes of channel spacing in 8.33 KHz, 12.5 KHz and 25 KHz in full compliance with the aeronautical telecommunication regulations and standards in force.
This new innovative radio TR-7700VUavailable from JOTRON, has been designed to meet the highest recurring expectations of various civil and military customers who need multi-channel joint V/UHF radios that combine versatility and high quality performance in a single compact package.
