Follow these steps to set it up:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eOpen the box, remove the \"jumper,\" and change the device to automatic control. This will automatically close the SDR receiving channel when the radio transmits.\u003c\/li\u003e\n\u003cli\u003eNo wiring is needed for the front panel jacks, and do not connect the distributed PTT line.\u003c\/li\u003e\n\u003cli\u003eUse the rear jacks for the power supply (VDC), radio (RADIO), SDR (SDR), and antenna (ANTENNA) interfaces. Connect each to its respective feeder.\u003c\/li\u003e\n\u003cli\u003eFor optimal performance, use feeders with good shielding and cover them with a magnetic ring.\u003c\/li\u003e\n\u003cli\u003eEnsure the device and radio shell are grounded to prevent the radio from interfering with the SDR during transmission.\u003c\/li\u003e\n\u003cli\u003eAfter removing the jumper, it is normal for the TRX light on the panel to be red constantly. When not transmitting, the SDR light will be green indicating it's in normal working state; it turns off when transmitting, which may cause indicators to flash and relay sounds.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003ePackage Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Host Device\u003c\/li\u003e\n\u003cli\u003e1 x Power Cord\u003c\/li\u003e\n\u003cli\u003e1 x 3.60cm SMA to SMA Connecting Line\u003c\/li\u003e\n\u003cli\u003e1 x PTT Control Line\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Evalm","offers":[{"title":"Default Title","offer_id":46819785867493,"sku":"7841898670585","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0712\/7262\/8453\/files\/5b2fd5c7-d69f-42a9-aa18-b01d21536786_jpg.webp?v=1731544118","url":"https:\/\/evalm.com\/products\/160mhz-sdr-transceiver-receiver-antenna-switch-box-with-gas-discharge-protection-copy","provider":"Evalm","version":"1.0","type":"link"}
