User Manual - Original Veronica® 1W PLL 12.2 1WPLLM

Previous Versions: PLL10 PLL11

28 years and still going strong, the Veronica PLL 12 is still the highest quality FM PLL for the price. It now has a pico micro-controller attached to it which allows easy up and down buttons for frequency and also corrects the RF ouput level so it's exactly 1 watt from 87.5 to 108 into 50 ohms. It also allows us to internet tcp/ip control the PLL12 remotely

CIRCUIT TESTING

1. Plug in a 50 ohm dummy load to the RF output OR Reduce the power to zero by turning VR2 fully clockwise.

DO NOT EXCEED 16V DC
DO NOT CONNECT + and - THE WRONG WAY

2. Apply between 12 and 16 volts to the PCB position marked CON6 +15V (+) and 0V (-)

3. Press the UP and DOWN buttons to select the frequency you require.

6. Apply audio at line level to CON1. Adjust the VR1 for correct FM deviation.

7. Remove the 50 ohm dummy load from the output OR Increase the power to full by turning VR2 fully anti-clockwise. You are now ready to install the 1W PLL into your transmission system.

If the 1 watt PLL is connected to a Veronica / Aareff Limiter Compressor or a Stereo Coder, pre-emphasis is not required. To disable the pre-emphasis, do not select 50uS or 75uS and remove the jumper completely. Store the jumper in a safe place just in case you need to restore the pre-emph for another application at a later date.
