Almost a decade on....Still the OEM manufacturer's preferred FM Exciter.
Its Compact, Low Noise, Linear deviation and Low Distortion characteristics make it first choice when performance is more important than cost.
The BW Broadcast BWPLL+ is a compact FM broadcast exciter with specifications that put many commercial exciters to shame. The modern innovative design allows audio and RF performance never before seen in kit or module exciters.
The 'virtual VFO' dual loop system allows audio flatness to 1 Hz. Afc bounce and modulator overshoot are a thing of the past. You now can pass that low bass without distortion and get that perfect stereo separation that you have been demanding from your exciter. Broadband no tune operation allows for ease of use. The only adjustment required is of the direct reading decimal dial switches for frequency selection. RF power is muted during out of lock conditions and the built in harmonic filter keeps your signal clean.
The expansion connector allows for external modules to be connected to the board such as the BW Broadcast BWPLL+ LCD.
The optional LCD expansion board provides frequency readout and the option of front panel frequency control with its PCB up / down switches.
"At this writing, the state-of-the-art in analogue modulated oscillator distortion is approximately 0.02% THD at ±75kHz deviation. In our opinion, if the THD of your exciter is less than 0.1%, it is probably adequate. If it is poorer than this (as many of the older technology exciters are), replacing your exciter will audibly improve sonic clarity and will also improve the performance of any subcarriers. Even if the distortion of your modulated oscillator is sufficient, the performance of the AFC loop may not be. A high-performance exciter must have a dual time-constant AFC loop to achieve satisfactory low-frequency performance. If the AFC uses a compromise single time-constant, stereo separation and distortion will be compromised at low frequencies. Further, the exciter will probably not accurately reproduce the shape of the carefully peak- controlled OPTIMOD-FM output, introducing spurious peaks and reducing achievable loudness."
An excerpt from maintaining audio quality by Robert Orban, Orban Inc, manufacturers of the Optimod audio processors explaining why an exciter with features like the PLL+ is better for your sound.

Best exciter module on the market today.
Bill from United States
working good without any problems
Claudio from Mexico
its a really good exciter, works good 24/7 without any problem

I have the one watt exciter and 20 watt amp,in testing
with a current meter in the power supply line my tests suggest
the Switch mode supply would not work at the required
current for the 20 watt module, however I will do more
testing and check this statement, this is great exciter

Excellent exciter I use it in all my LPFM projects. Be good if the lcd was included tho but cant get better for the price.
