Description

This is a nice fast Hotspot made with a Pi 3 B +. This is a Duplex Hotspot so no more waiting for the long-winded talker, go to time slot 1 or 2 and put it on a new talk group. Now you can switch back and forth between talk groups easyer, it is like having 2 hot spots. Duplex MMDVM Hotspot UHF/VHF P25 DMR YSF D-Star M17 plus more. Running Raspberry Pi 3 B+ with a nice colored OLED Display. Running Pi-Star: 4.1.8 (Latest version) Raspberry Pi 3 B+ Pi-Star loaded on SD card, you just need to configure your call and Wi-Fi, as well as a couple of other personal info than you're on the air. Specification: Broadcom BCM2837B0, Cortex-A53 64-bit SoC @ 1.4GHz Memory: 1GB Connectivity: • 2.4 GHz and 5 GHz IEEE 802.11b/g/n/ac wireless LAN, Bluetooth 4.2, BLE• Gigabit Ethernet over USB 2.0 (maximum throughput 300Mbps)• 4 × USB 2.0 interface Video and sound: • 1 x full size HDMI• MIPI DSI display port• MIPI CSI camera port• 4 pole stereo output and composite video port Multimedia: H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30); OpenGL ES 1.1, 2.0 graphics SD card support: Micro SD format for loading operating system and data storage Input Power: • 5V/2.5A DC via micro USB connector• 5V DC via GPIO header• Power over Ethernet (PoE)-enabled (requires separate PoE HAT) Operating temperature: 0-50°C Production lifetime: Raspberry Pi 3 Model B+ will remain in production until at least January 2028 WIDELY COMPATIBLE: Supports DMR, P-25, D-Star and System Fusion Differences in Duplex and Simplex: In Duplex mode, have 2 time slots, and Tx and Rx. Radio Frequency: In duplex mode, support 430-440 uhf, in simplex mode support both uhf 430-440MHz and vhf 140-150MHz Best adjusted: TX =0, RX=0 need no offset. Modem select: STM32-DVM/MMDVM_HS-Raspberry pi Hat(GPIO) 3D Printed Case: For high RF performance over metal case. Antenna: On board two antennas and 2.42" OLED SD Card included with Pi image installed I have other hotspots on eBay as well take a look at the different kinds I have available. www,w1vet.com
