Designed for both amateur and commercial UHF operations, it handles FM, SSB, CW, and digital modes with equal efficiency.\u003c\/p\u003e\u003cp\u003eRF sense keying removes the need for a PTT connector, and the built-in 20dB low-noise receive preamplifier means no external preamp is required for receive. Front panel power and SWR metering, automatic fault protection above 2:1 SWR, and four settable power output steps (30W to 80W+) give full control in a compact heatsink chassis.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequency: 430–470 MHz (UHF)\u003c\/li\u003e\n\u003cli\u003eOutput power: up to 80W (4 steps: 30W to 80W+)\u003c\/li\u003e\n\u003cli\u003eInput drive: 3–5W; bypass at up to 50W when amp is off\u003c\/li\u003e\n\u003cli\u003eModes: FM, SSB, CW, and digital\u003c\/li\u003e\n\u003cli\u003eRF sense keying — no PTT connector required\u003c\/li\u003e\n\u003cli\u003eBuilt-in low-noise receive preamplifier: 20dB nominal gain\u003c\/li\u003e\n\u003cli\u003eFront panel power and SWR metering\u003c\/li\u003e\n\u003cli\u003eAutomatic fault protection for SWR over 2:1\u003c\/li\u003e\n\u003cli\u003eMode switch for SSB delay and peak power metering\u003c\/li\u003e\n\u003cli\u003eType N female connectors (RF input and output)\u003c\/li\u003e\n\u003cli\u003e60cm DC power cable with tinned leads (unterminated)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequency: 430–470 MHz\u003c\/li\u003e\n\u003cli\u003eOutput power: 80W max (4 steps from 30W)\u003c\/li\u003e\n\u003cli\u003eInput: max 5W; bypass: max 50W\u003c\/li\u003e\n\u003cli\u003eDC input: 13.8V DC @ 13A max (10.5–14.8V operational range)\u003c\/li\u003e\n\u003cli\u003eConnectors: Type N female (in\/out)\u003c\/li\u003e\n\u003cli\u003eDimensions: 125 × 50 × 210mm\u003c\/li\u003e\n\u003cli\u003eWeight: 1.15 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Toptek","offers":[{"title":"Default Title","offer_id":57529572426072,"sku":"MOON-99-295","price":249.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/pa-80u-01.jpg?v=1781703648","url":"https:\/\/kamsat.co.uk\/products\/pa-80u-430-470-mhz-80w-power-amplifier","provider":"Kamsat","version":"1.0","type":"link"}
