Where generic RTL-SDR dongles offer 8-bit dynamic range and limited HF sensitivity, the HF+ Discovery delivers 18-bit effective ADC resolution with a noise floor that competes with high-end bench receivers costing 10× as much.\u003c\/p\u003e\u003cp\u003ePurpose-engineered for the shortwave and HF bands (AM broadcast, international SW stations, 160m through 10m amateur bands, utility stations, STANAG signals, and the MW\/LW spectrum), it also covers VHF up to 260MHz. The dual-path front end uses separate LNA and mixer chains for the HF and VHF bands, eliminating the image rejection compromises inherent to direct-conversion designs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFrequency range: 0.5kHz–31MHz (HF) + 60–260MHz (VHF)\u003c\/li\u003e\n\u003cli\u003eDynamic range: 120 dB per decade\u003c\/li\u003e\n\u003cli\u003eEffective resolution: \u0026gt;18 bits\u003c\/li\u003e\n\u003cli\u003ePhase noise: −130 dBc\/Hz @ 1kHz offset\u003c\/li\u003e\n\u003cli\u003eSMA antenna input with selectable impedance\u003c\/li\u003e\n\u003cli\u003eUSB 2.0, powered from USB\u003c\/li\u003e\n\u003cli\u003eCompatible with SDR#, HDSDR, SDR-Console, SDR++\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54186573758756,"sku":"GPP-AIRSPY-HF-DISC","price":169.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/hfplus_discovery.png?v=1780551872","url":"https:\/\/shop.goldenphysics.org\/products\/airspy-hf-discovery-high-performance-hf-vhf-sdr-receiver","provider":"Golden Physics Project","version":"1.0","type":"link"}
