Microwave Radio Links
Synthesized input frequency from 48 to 1020 MHz. The local oscillator is constituted of a direct synthesis circuit with possibility of reception frequency changes using internal dip-switches. No substitution of the crystal is necessary. The input filter need to be realigned in the event of a reception frequency change. This is done using the front panel meter and a screwdriver .
Synthesized output frequency (from 830 to 1020 MHz) within the same bands of input frequency. Frequency can be easily changed using internal dip-switches .
Adjustable output power (5W) between zero and maximum value indicated on each model's specifications .
Thermostated crystals: allow a reception and transmission of higher precision and stability, also in variable temperature conditions. This means a general improvement of hop distorsions, very harmful for stereo transmissions.
IF 10.7 MHz output allows to realize easily deviations for further radio-link hops or for transmission in the 87.5 to 108 MHz band .
Demodulated BF output to monitor reception signal. Useful to check passing signal. Available with excludable 50/75 µs de-emphasis .
External adjustable squelch and excludable, which allows to fix the silence threshold at the most suitable value. Upon request, a 110/220 Vac output controlled by squelch circuit, is available .
Metering instrumention and controls are located on front panel .
Battery power supply. 12 Vdc power supply can be added, on request, to the 110/220 Vac standard one .
