Replacing legacy technology with a Nautel NX Series MW transmitter running MDCL could yield energy savings of up to $100,000 USD per year based on real world examples.

Considering that the cost of buying a transmitter is as significant and important as the running cost associated with them, exceptional efficiency and low maintenance overhead make this transmitter extremely cost effective to own and operate.

With power outputs of 3 kW to 2000 kW, the NX Series sets a new standard for digital performance, rugged design and operational ease in the industry’s most compact enclosure. Add AM digital precorrection, up to 90% efficiency plus an intuitive touch screen interface and the result is the most advanced medium wave transmitter available today.

For example, if you use a 2.5kW transmitter with NX Power 3 with MDCL technology 24 hours a day, your total yearly consumption could come down from 37,668 kW/H to 23,652 kW/H, bringing down the total energy cost up to $3062.

NX Series transmitters are provided complete with built-in instrumentation that would cost tens of thousands of dollars if purchased separately. Nautel’s patented, real-time impedance measurement technology allows the antenna system load impedance to be optimized and monitored while the transmitter is operating normally. The transmitted voltage and current waveforms are compared to measure the load impedance over the operational frequency range. Because this system can measure impedance without requiring artificial swept tones, the antenna system impedance locus can be measured without taking the station off-air. Impedance is measured at the combiner so no correction for harmonic filter phase is required. NX transmitters also utilize a built-in directional coupler for spectrum measurement instead of a traditional voltage or current sensor. The directional coupler increases the accuracy of spectrum measurement into a real antenna load which is quite important when measuring adjacent channel emissions.

Overall efficiency is typically up to 90%* or better. The high efficiency means less energy is wasted as heat, which reduces cooling and ventilation costs. The resulting savings could amount to thousands of dollars per year.

NX Series transmitters are typically one half to one third the size of comparable high power medium wave transmitters. That makes planning your NX transmitter deployment that much easier and gives you flexibility too. As an example, you may be able to avoid expanding existing facilities or building new ones. Or possibly a portable shipping container enclosed NX could be used as an emergency back up to existing facilities or to provide backup transmission during periods of major facility maintenance. While NX Series transmitters may be compact they still offer easy and spacious access to all major serviceable components and modules ensuring easy maintenance.

Nautel NX Series transmitters come standard with power saving technology commonly referred to as Carrier Control Algorithms or Modulation Dependent Carrier Level (MDCL). Power savings of up to 30% or more may be realized with minimal impact on the received signal quality and the coverage area.
