Police radio and other types of two-way radio often use simulcast to increase range. Frequency control is crucial in these systems. In the past, frequency control was accomplished by using matched quartz oscillators. This ensured that the oscillators at all sites were very close in frequency, but it also required calibration at each transmit site once or twice a year for low- and high-band systems. Re-calibration at UHF and 800 MHz systems needed to occur much more frequently. Maintaining and calibrating oscillators on a regular basis could be very costly.

Most frequency control methods today reference the Global Positioning System (GPS). This method requires no re-calibration and the frequency accuracy is better than 0.01 hertz at the carrier frequency. 咪咕体育直播 offers several helpful products to minimize costs when upgrading a simulcast system.

One such product is the Tycho II Precision TimeBase. The Tycho II is a v
