Driven by as little as 1W and up to 35W input, it delivers a maximum output of 500W, making it compatible with virtually any CB or 10m transceiver. The switch-mode power supply (SMPS) accepts 100–240V AC worldwide, is both lightweight and highly efficient, and eliminates the need for a separate heavy linear PSU. A large heatsink with two cooling fans ensures quiet, reliable thermal management during extended operation. Harmonic output is greater than −50 dBc — no additional filtering required for FCC compliance. Comprehensive protection circuits guard against excessive input drive, high antenna VSWR, over-temperature, and out-of-band transmissions. Supports both VOX (with SSB delay) and PTT switching modes.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e500W maximum output power\u003c\/li\u003e\n\u003cli\u003eFrequency range: 25–30 MHz (CB 27 MHz \u0026amp; 10m amateur)\u003c\/li\u003e\n\u003cli\u003eInput power: 1–35W (all modes)\u003c\/li\u003e\n\u003cli\u003eSwitch-mode power supply: 100–240V AC worldwide\u003c\/li\u003e\n\u003cli\u003eVOX (with SSB delay) \u0026amp; PTT switching\u003c\/li\u003e\n\u003cli\u003eHarmonic output: \u0026gt;−50 dBc — FCC compliant, no additional filtering required\u003c\/li\u003e\n\u003cli\u003eProtection: excessive input drive, high VSWR, over-temperature, out-of-band\u003c\/li\u003e\n\u003cli\u003eLarge heatsink with dual cooling fans for quiet, reliable operation\u003c\/li\u003e\n\u003cli\u003eInput VSWR: 1.1–1.5:1\u003c\/li\u003e\n\u003cli\u003eDimensions: 415 x 305 x 170mm (L x W x H)\u003c\/li\u003e\n\u003cli\u003eWeight: 13kg\u003c\/li\u003e\n\u003cli\u003eMade in Italy by RM Italy\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFrequency: 25–30 MHz\u003c\/li\u003e\n\u003cli\u003ePower supply: 100–240V AC (SMPS)\u003c\/li\u003e\n\u003cli\u003eInput power: 1–35W max (all modes)\u003c\/li\u003e\n\u003cli\u003eOutput power: 500W max\u003c\/li\u003e\n\u003cli\u003eInput VSWR: 1.1–1.5:1\u003c\/li\u003e\n\u003cli\u003eHarmonic output: \u0026gt;−50 dBc\u003c\/li\u003e\n\u003cli\u003eSwitching: VOX (with SSB delay) \u0026amp; PTT\u003c\/li\u003e\n\u003cli\u003eDimensions: 415 x 305 x 170mm (L x W x H)\u003c\/li\u003e\n\u003cli\u003eWeight: 13kg\u003c\/li\u003e\n\u003cli\u003eCountry of origin: Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RM ITALY","offers":[{"title":"Default Title","offer_id":56981510259032,"sku":"MOON-99-354","price":849.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/bla703.png?v=1774520621","url":"https:\/\/kamsat.co.uk\/products\/rm-bla703","provider":"Kamsat","version":"1.0","type":"link"}
