Nautel’s VS300LPFM is an investment in quality transmission for your station. The VS offers built-in instrumentation, remote management and advanced capabilities that can save your LPFM or community station thousands of dollars.

The most advanced Low Power FM transmitter available, Nautel’s VS300 is ideal for use by community, religious, educational and other non-profit radio groups. The award-winning VS300 transmitter recently received type certification from the FCC to be used in LPFM applications.

When designing the VS300 LPFM special consideration was given to the needs of Low Power stations. Nautel wanted to offer a transmitter that simplified the installation process and could be easily automated and controlled while providing the flexibility to broadcast any type of programming in any format imaginable.

With a strong history of supporting local radio Nautel is happy to be able to offer a product that has been designed to meet the unique needs of low power, community, and religious broadcasters. The VS300 for LPFM is a unique platform that eliminates many of the peripheral components that are often required even in a first time low power installation. This integration of components that traditionally required their own hardware greatly simplifies the set-up, operation and maintenance of a LPFM station and most importantly helps keep costs down.

Main Features:
• Built-in Commercial Grade Instrumentation: A feature initially developed for our high power NV Series transmitters, all VS300 low power transmitters are equipped with RF and audio spectrum analyzers. Pre configured to allow instantaneous analysis without the need to set up or purchase expensive stand alone equipment costing thousands of dollars, these tools open up a whole new world of professional grade instrumentation for low power broadcasters.
• Advanced User Interface (AUI) Features: The AUI can be accessed locally with a user provided laptop and remotely using the internet. Screens are easy to set up and read, and clearly display the parameters you need to see. No matter where you are, you’re only moments away from ensuring your transmitter is operating optimally. AUI functionality includes: *Instrument grade audio spectrum analyzer *Comprehensive monitoring and control *Extensive logging of all events *Presets and easy transmitter control
• 100% Remote Access: No matter where you are, you’re only moments away from ensuring your transmitter is operating optimally. Open a web browser on your computer or smart phone (that supports Flash, VNC or VPN), enter your transmitter’s IP address and password and you’re connected. 100% of the local display functionality is available on web-enabled devices. Whether your troubleshooting issues at the transmitter site or making last minute changes to your programming, it can all be done remotely.
• SNMP Support: The AUI also supports Simple Network Management Protocal (SNMP), a network protocal that allows network management systems or a network operations center (NOC) to monitor network-attached transmitters
• IP AUDIO I/O: The VS Series are the first transmitters ever to implement Axia’s Livewire Studio to Transmitter Audio over IP Workflow. The result is a seamless digital IP audio path from a host of Livewire compatible devices directly into a Nautel transmitter ensuring outstanding audio purity via a CAT 5 cable. If you stream your station on SHOUTcast you can even use it as an input should your STL fail.
• USB Hard Drive or Memory Stick Automation: When you add this much intelligence and IP I/O to a transmitter you’ll be amazed by what you can do. Nautel added a USB port so that you can connect a megabyte or even a terrabyte of local storage. Use the storage to store content or even load up the songs and content using the VS internet connection. Once you have audio loaded it can become part of the automated back up audio capability should all other connections fail.
• New Playlist and Automation Functionality : If you think the local audio storage mentioned above sounds interesting you’ll want keep your eye on soon to be released VS Series playlist and scheduler capability. From your office or anywhere for that matter you can set up basic automation capabilities to playout audio or insert local content. It’s like putting part of the studio inside the transmitter. Stay tuned for more capability in the VS by way of something we call Push Radio that can help satellite connected stations slash costs and provide more local content.
• Proven Reliability and Ease of Ownership: Every rugged and reliable VS Series transmitter is the result of years of Nautel design expertise and is crafted completely within Nautel’s North American manufacturing facilities. Compact, value-optimized packaging, easy-to-access washable air filters, published parts lists and screw driver replacable power FETS make living with your VS transmitter easy for years to come. Join the growing ranks of over 2,000 customers who have deployed VS Series transmitters and learn why Nautel transmitters and support are counted on for decades of service.
