VLA-200V amplifier has an output power of 200W FM and SSB in the 2 meters when driven with a signal of 50 W Max. Large sink is equipped with two large fans to ensure sufficient cooling to transistors. Mounts a preamplifier in receiving with 10 to 25 dB gain which can be selected.
The UHF amplifier ULA-100 is similarly constructed but no fans and preamplifier. Its power output is 100W in the 70 cm with a maximum input power of 5Watt.
Both amplifiers are equipped with a VOX circuit but can also be operated with a PTT switch line (useful on SSB). The power output and operating status are displayed by LEDs on the front panel. To ensure trouble-free operation include protections against reverse polarity, against ROS too high and against excessive temperatures. The amplifiers need 12-14 Volt DC power supplies, 22nd highest.
