It has two ADF7021 onboard and allows for duplex operation with two time slots on DMR.The default bit error rate is less than 5%, and the default 0ffset is 0. If the bit error rate is more than 5%, as long as the signal can be received, it can be corrected by 0ffset.\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e - Fully tested- Supports DMR, P-25,D-Star and System Fusion- Onboard LEDs to show status (Tx,Rx,PTT,Mode)- Up to 10mW RF power- SMA antenna connector,Antenna included- Mounts cleanly on all current Raspberry Pi's including the Pi Zero- The firmware is pre-loaded and is easily upgraded via software.- UHF 430-450 MHz,433mhz and 900MHz\u003cb\u003eVHF 144 220 Opera FREQ:\u003c\/b\u003eThe upper part is TX,the lower is RX antenna.UHF+VHFSMA,antennaModem select: STM32_HS_GPIOSet TX frequency,RX frequencyTX,RX frequency had better 10M or more apart.SLOT1,SLOT2 support.\u003cb\u003ePackage includes:\u003c\/b\u003e1 x MMDVM duplex HotSPOT Module2 x Antenna(UHF)2 x SMA socket1 x Aluminum alloy shell\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/84\/2C\/385b5c45-e773-4bda-9732-d397519d6eac.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/E3\/D5\/dee4a10d-927b-4086-b595-134e5e66c52a.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/E1\/41\/0354ba29-6bce-4253-bf16-fab036bb8340.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"http:\/\/imgmgr.banggood.com\/images\/oaupload\/banggood\/images\/79\/BC\/9b011b4c-0901-44c8-97ff-a9d9721f00d2.jpg\" style=\"width:1000px\"\u003e\u003c\/p\u003e","brand":"HappyFish.co.za","offers":[{"title":"Unassembled","offer_id":46807785308381,"sku":"2038131-POA11747845","price":1167.69,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/8507\/4360\/files\/385b5c45-e773-4bda-9732-d397519d6eac_jpg.webp?v=1780425967","url":"https:\/\/happyfish.co.za\/products\/raspberry-pi-duplex-mmdvm-digital-hotspot-board-uhf-vhf-dual-timing-support-dual-antennas-ready-to-use","provider":"HappyFish.co.za","version":"1.0","type":"link"}
