The amplifier automatically detects the transmitting frequency and switches to the appropriate signal path — no manual band selection required.\u003c\/p\u003e\u003cp\u003eIndependent ALC-controlled power output settings for VHF and UHF allow each band to be optimised separately. A moving-dot SWR display provides real-time VSWR readings from 1.20 to 1.90, with LED blink indicators for underrange (below 1.20) and overrange (above 2.00). Twin MOSFET push-pull amplifiers — one per band — deliver 85W ALC-limited output from 5W of input drive, with 60dBc harmonic suppression.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDual band: VHF 138–174 MHz and UHF 430–470 MHz\u003c\/li\u003e\n\u003cli\u003eAutomatic band detection — switches signal path without manual input\u003c\/li\u003e\n\u003cli\u003eIndependent ALC power control for VHF and UHF\u003c\/li\u003e\n\u003cli\u003eMaximum output: 85W (ALC limited)\u003c\/li\u003e\n\u003cli\u003eInput range: 1–10W; full output at 5W (frequency dependent)\u003c\/li\u003e\n\u003cli\u003eTwin MOSFET push-pull design — two independent amplifiers\u003c\/li\u003e\n\u003cli\u003eMoving-dot SWR display (1.20–1.90) with under\/overrange LED indicators\u003c\/li\u003e\n\u003cli\u003e60dBc harmonic suppression\u003c\/li\u003e\n\u003cli\u003eBypass power: 50W\u003c\/li\u003e\n\u003cli\u003eModes: FM, AM (with caution — see note below)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVHF frequency: 138–174 MHz\u003c\/li\u003e\n\u003cli\u003eUHF frequency: 430–470 MHz\u003c\/li\u003e\n\u003cli\u003eMax output: 85W (ALC limited)\u003c\/li\u003e\n\u003cli\u003eInput range: 1–10W (full output at 5W)\u003c\/li\u003e\n\u003cli\u003eBypass: 50W\u003c\/li\u003e\n\u003cli\u003eHarmonic suppression: 60dBc\u003c\/li\u003e\n\u003cli\u003eCircuit: Twin MOSFET push-pull (independent VHF and UHF amplifiers)\u003c\/li\u003e\n\u003cli\u003eDimensions: 50 × 125 × 210mm\u003c\/li\u003e\n\u003cli\u003eWeight: 1.15 kg\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eNote: AM mode can be used with caution — set ALC power to maximum and adjust drive to achieve approximately 20–30W output, leaving headroom for modulation peaks.
