Introduction
The BW Broadcast V2 is the latest development in a high specification range of FM transmitters over 15 years in the making.
Its broadband “no-tune” design allows 87.5 - 108MHz operation without requiring tuning or calibration. The inclusion of four-band DSPX audio processing means stations without a dedicated processor sound great, right out of the box. Those who already have external processing benefit from BW Broadcast’s unique dual-loop virtual VFO exciter and field proven ultra-low distortion modulator integrated into a great performing, highly stable FM transmission system.
Features such as slide-in power supplies, and unique solder-free Gold-Clamp transistors (not present on all models) make in-field maintenance simple.
A high resolution OLED screen displays RF, audio and system parameters. The control wheel and three front panel buttons allow easy navigation of the menus. Help tips for every parameter make setup simple without having to refer to the technical manual
Every V2 Transmitter features a LAN connection for Ethernet local or remote control. The LAN connection also supports SNMP, telnet, and email alerts via either SMTP or BW Broadcast’s mail server. Where a LAN connection is not available, the RS232 connection can be used.
Intelligent alarms and email alerts ensure busy engineers can manage their stations with minimal intervention. A real time clock and comprehensive logging is available for those who like to see more detailed status. Also present are 4 rear panel opto-isolated triggers that allow external equipment to control the transmitter.
It is advised that this manual is read to learn all of the advanced features of the V2 Transmitter.

Status Box
This section of the display gives real time information about the status of the transmitter
A - Frequency
The target frequency of the transmitter. When the transmitter is tuning to frequency on start-up, this will flash between full and half brightness, When the transmitter is locked, it will remain at full brightness
B - Power
The actual power of the transmitter. After the transmitter has locked on frequency, the power will ramp up to the set level. During this time the power display will flash between full and half brightness, When the power level is locked, it will remain at full brightness. If RF Mute is set either manually or automatically, this section displays "RF Mute".
C - Deviation
Shows the current peak FM deviation of the transmitter. If the deviation falls below 30kHz for 30 seconds the deviation display will flash.
D - Alarms
Indicating alarms which are set or triggered. The letters A-C indicate when an alarm is enabled and when an alarm is triggered. Each alarm has two states:
A - Greyed out - Alarm is enabled but not triggered.
→ A → 
- Alarm is flashing - Alarm has been triggered.
For example:
Not Shown
ALM A
ALM ABC
ALM ABC
ALM ABC - All alarms are triggered.
An indication the alarms have been triggered will also be shown on the screensaver.
E - PA temperature/Power supply voltages
Displays the temperature of the Power Amplifier and the voltages of the Power amplifier power supply and of the auxiliary power supply:
PA T: 30°C - Power amplifier temperature, nominally around 50°C for an ambient temp. of 25°C PA V: 30.6VVoltage of power amplifier power supply, varies between 8V and 50V Dependent on
power setting and model
AUX: 15.2V - Voltage of auxiliary power supply for the control system and exciter of the transmitter. Should be 15V ±0.3V
If FSK is enabled, this section will read FSK ACTIVE while the transmitter is keying as shown below:
