Special Features:

Item provides 156.025/157.425 mhz recvr injection signal or 180.775/187.050 mhz transmit drive signal; freq range selection is dependent on voltage applied to varactors in the voltage controlled oscillator circuit; in the transmit mode a 3rd varactor in the oscillator circuit permits freq modulation of the transmit drive signal; items c/o components mtd on pwb; 4.375 in. Lg; voltage rating: 12.5 vdc, temp range -35/+65 degrees c; nom. Temp rating 25 degrees c

Properties:

An electrically heated compartment designed to accommodate and maintain at an essentially constant temperature, one or more components, such as, crystal unit(s), quartz; tuned circuits; integrated circuit devices; and semiconductors. It prevents frequency drift and changes in teperature.
