![]() ![]() To setup FreeNX and/or X2Go on a Linux server. This source tree started as a re-distribution of those NX packages needed for fast simple frequency change capability without the need of special tools or external test equipment.NX development by ArticaProject, X2Go and TheQVD.with a unique circuit which dynamically stabilizes power against AC line voltage variations – after an AC power loss, over voltage or RF overload, prior operating status is automatically restored,.to stay on the air without human supervision thanks to a high VSWR threshold of 1.5:1 and automatic fold back in more extreme VSWR situations,. ![]() Should a failure occur, the transmitter automatically switches over to the built-in standby exciter, dramatically enhancing the already high operation reliability inherent in the modular solid-state design. Compact footprints, published parts lists, and screw driver-replaceable power FETS make living with your NX transmitter easy.Ī unique feature of Nautel MW transmitters is the complete duplication of the exciter section, providing RF carrier and modulation control signals to the power modules. The NX Series incorporates solid state components in a rugged, highly redundant, hot swap architecture. Analog, all modes of DRM 30 or HD Radio ® are all supported today in this tri-mode design. The inherent linearity means that your NX transmitter is prepared for the future. The result is an ultra linear digital broadcast transmitter design that is scalable from 3 kW to 2 MW. Specific pre-correction techniques include:Īll pre-correction filters can be monitored from the front panel display. NX Series pre-correction corrects for all primary forms of distortion which typically affect both analog and digital AM broadcasting. NX transmitters achieve outstanding linearity by employing a unique six phase Direct Digital Modulation that is encoded at an unprecedented 1.8 mega-samples per second. Then they pushed the limits of transmitter design by adding the best digital pre-correction available.First they designed a transmitter so linear that no pre-correction would be needed.To design the industry’s best digital transmitter our engineers applied two guiding principles: Even the exciter is duplicated and automatically switches to the standby exciter in the event of an RF drive failure.īuilding the Industry’s Best Digital Transmitter ![]() Ventilation is provided by redundant brushless DC ball bearing fans mounted in removable trays below the power modules.Īirflow is unaffected by AC supply variations, further ensuring cool operation and long term reliability. Repair or replacement can be performed whenever it is convenient. If an amplifier fails, no stress is imposed on the remaining modules and spectral integrity is not compromised. At all power and modulation levels, all modules contribute equally to the final output. As an example, in the NX400, 160 amplifiers combine to deliver up to 600 kW of average power (carrier plus modulation). Using numerous high capacity modules affords the utmost in reliability and on-air power output consistency. NX Series transmitters are engineered to provide easy on-air service and maintenance.Īn NX100 uses 40 high capacity modules while a 1 MW configuration would have 400 individual modules.
