1. Preface
This document provides operator information on how to set up the MT300 (Ethernet to
Broadcast) Pico Broadcaster. This device requires professional installation and the use of
tools and procedures for determining location, minimum power requirements.
2. IMPORTANT NOTICES
FCC Part 15 Information to the User
Caution: Changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
Note: This equipment has been tested and found to comply with the rules for TV bands
devices, pursuant to part 15 of the FCC rules. These rules are designed to provide
reasonable protection against harmful interference. This equipment generates uses and
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. If this equipment
does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
(1) Reorient or relocate the receiving antenna.
(2) Increase the separation between the equipment and receiver.
(3) Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
(4) Consult the manufacturer, dealer or an experienced radio/TV technician for help.
RF Exposure
The radio described in this manual transmits RF energy. The concentrated energy
from the antenna may pose a health hazard. All antennas used with this radio must be
installed to provide a minimum separation from all persons of 40 cm (15.7 inches). The
above separation distance must be maintained at all times. More information can be
obtained from the FCC at the following website:

3. Introduction
The Meld Technology MT300 White Space radio must be professionally installed by a
trained installer. The installation must be in accordance with 47 CFR Part 15 Subpart H
and the instructions contained in this manual. Only the following components are
approved for use with the radio.
Power Supply: Stontronics 3A-401WP12
Antenna: U Tek Technology Co. EA-79X-1
3.1 Overview
MELD develops Pico Broadcast products for wirelessly distributing content to any DTV
ever made for the North American market using newly opened white space frequencies
and broadcast standard modulation methods.
The advantages of Personal Broadcast based solutions are:
Lower cost labor for installation, modification and support
Economy of scale using standard DTV receivers and components verses other
specialized non-standard receivers and communication methods.
MELD’s Pico Broadcaster sends live full HD content wirelessly to any number of DTVs
located in an unobstructed effective range of 360 feet, about the size of a football field.
No cabling or infrastructure equipment investment needed.

3.2 General Description
Figure 1 - Typical Setup for Device configuration and TVWS access
The MT300 is an easy to use Fixed TV bands device using a VSB modulator that is
designed to provide low-power transmission of a DTV compatible signal over a limited
area. It is designed to not interfere with licensed broadcast transmissions and complies
with the FCC CFR 47 Part 15 subpart H rules for TV Band devices. It is designed to
work with the tuner input of any Digital TV sold in North America. The MT300 is
designed to accept properly formatted MPEG2 transport streams from a local PC running
VLC or similar streaming software or a media server. The transmitted signal is compliant
with the tuner input of a Digital TV receiver.
3.4 Intellectual Property Warning
Some of the concepts described in this document are protected by appropriate patent
protections or other legal means. These areas are identified in the text as being
proprietary. For additional information on these subjects please contact MELD directly.
The device described herein is protected by US Patent #8,063,996, other patents pending.

The device has two IP address:
System Control CPU (default)
IP address: 192.168.1.194,
Gateway IP: 192.168.1.254
This address points to a web form used for user registration and setting up the
radio for FCC compliant operation including database access, and radio control
for operational parameters of the system, such as preferred channels and power.
Digital Modulator (default IP address)
IP: 192.168.1.193
Port: 5002
This IP address is for Transport Stream content going directly to the MELD
Digital Modulator for ATSC modulation.

3.6 Applications in Digital Signage
Pico Broadcast HD video distribution would enable airports, hotels, restaurants, bars,
schools, hospitals, professional, industrial applications to wirelessly send high-quality
video to any number of screens.
•Proven reliable: Used around the world; day in, day out, digital broadcast TV
reliably sends perfect clear HD images and sound over large areas.
•Completely wireless: No messy wires run, hide or trip over.
•No external box need: Signal is 100% compatible with any DTV ever built.
3.7 List of abbreviations
ATSC is the Government "Standard" for the Digital (RF) Broadcast Signal
8VSB is the name of the modulation standard used in ATSC Systems
SMPTE 310M is the electrical interface that carries MPEG-2 transport streams to 8VSB
modulators
PSIP is the name of the "table" structure that defines the structure and order of the MPEG
Streams in a valid broadcast stream ... per government regulations of USA

4. Installation
4.1 Front/Rear Panel Interface
Note: It is recommended the MT300 be installed and located in a secure area such as a
network closet or operations center. The device must be installed in a location that
provides a minimum separation from all persons and the antenna of 40 cm (15.7 inches).
Please refer to the RF Exposure warning on page 3.

4.2 Setting up the MT300 for first time use
Recommended Network Setup
Note: The MT300 needs internet access to be able to operate. The transmitter will not
be enabled until the device successfully registers with and receives a channel list from the
TV Bands database service.
Use of the setup in figure 1 and configuring the router LAN IP address set to
192.168.1.254 will allow access to the White Space database for registration. Set the
computers network setting in figure 1 to DHCP to acquire an address from the router.
Connect the antenna provided to the RF port located on the back panel of the device.
(Use of a different antenna other than the one provided is prohibited)
Plug-in the power supply adapter supplied with the MT300.
(Use of a different power supply other than the one provided is prohibited)
The MT300 is shipped with the factory default network settings below and are assumed
unchanged for the recommended network setup.
Factory Default Network Settings
Configuration Type - Static
IP Address - 192.168.1.194
Subnet Mask - 255.255.0.0
Gateway Address - 192.168.1.254
Primary DNS - 192.168.1.254
Secondary DNS –
Streaming IP Address – 192.168.1.193
Using your PC internet browser; type http://192.168.1.194 in the browser URL field to
access the device webpage interface. The device registration tab will be displayed. To
complete the device registration process, proceed to the Device Registration section
below for registering your device.
Custom Network Setup
Note: Currently, the MT300 only supports network subnets that are limited to
192.168.0.0.
The MT300 is shipped with the factory default network settings above. To change the
default network settings to be compatible with your network addressing scheme use the

setup in figure 1 or use the alternative setup below in figure 2 to change the MT300
network configuration.
If using the typical setup in figure 1, connect a PC and the MT300 to the router and set
the computers IP Address to a static IP address on the same subnet as the default settings
for the MT300 (e.g., 192.168.1.100). The LAN side of the router must be configured for
addresses within the 192.168.0.0 subnet.
Figure 2 – Alternative setup for device configuration
If using the alternative setup for device configuration, connect a PC to the MT300
Ethernet port and set the computers IP Address to a static IP address on the same subnet
as the default settings for the MT300 (e.g., 192.168.1.100).
Using your PC internet browser; type http://192.168.1.194 in the browser URL field to
access the device webpage interface. The registration tab will be displayed.
