1W PLL 'EASY-TUNE' TRANSMITTER (PLL3)
HIGH PERFORMANCE KIT RANGE
Perfect Audio Every Time.....
The Veronica 1W PLL first marketed in 1996 is still the favorite choice for broadcast engineers at all levels from the hobbyist through to the professional licensed operator. In early 1998 the PLL 2 was released and then in January 2000 the latest version was released, the PLL 3 'Easy-Tune'.
Without any amplifier tuning the PLL 3 produces a clean flat 1W output from 87 to 109 MHz, this is a match made in heaven for our high quality 12W and 25W variable output 'No-Tune' RF power amplifiers. Reliability is now even better with an improved cooler running broadband RF output amplifier. The RF output device is rated at 1.8 watts, since the PLL 3 is running at only 1W, stabilty and ruggedness is excellent even at very high
The audio signal to noise ratio is better than -80dBu, this is achieved by using a lightly loaded high stability half frequency push-pull Hartley oscillator for generating the RF signal. The output of the Hartley oscillator is configured as a frequency doubler using a push-push arrangement, filtered and amplified by two high stability amplifiers to 1 watt.
All the parts for the 1W PLL 3 are readily available all over the world should you ever need spares. The PLL circuitry is 100% hardware controlled and will never suffer from software bugs or processor crashes. The ICs are the standard TTL 74... series and CMOS 4000 series.
This PLL synthesizer is specially designed for high quality wideband FM with an audio frequency response that's near flat from 30Hz to 76KHz with selectable pre-emphasis. This important feature provides optimum stereo separation when used with a stereo coder. CD's and other audio sources are reproduced with the finest of clarity. As with the original PLL and the PLL 2 expensive test equipment is not required to set up the transmitter. Setting up the unit ready for broadcasting is made easy using the built in LED's that indicate power output and lock conditions.
The Veronica PLL is known throughout the world as professional class equipment at excellent value for money. Thousands of stations throughout the world now use Veronica products for high quality broadcasting.
