Description

UHF 1W SHARI SA818 Ham Allstar Radio Interface Compatible Raspberry Pi 2/3/4
hosted Allstar node hotspot
Description:
SHARI (SA818 Ham Allstar Radio Interface) is a ham construction project designed by N8AR that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 -450 MHz) radio module. SHARI is designed for construction and use in the amateur radio service by licensed amateur radio operators who can assure that their assembled SHARI kit meets FCC mandated operating requirements including RF frequency, deviation and required power levels at the fundamental and harmonic frequencies.
In order to create an Allstar node, SHARI plugs into two USB jacks on a Raspberry Pi2/Pi3 or Pi4 for power, the Allstar interface and radio programming (a short M/F USB extender cable can be used if desired).
Front panel LEDs indicate the status of SHARI – [POWER (green), USB Audio CONNECTION STATUS (blinking green), COS (green) and PTT (red)] . SHARI RF output power is 500 to 1000(default) milliwatts.
Features：
Works with a Pi2/Pi3 or Pi4 (USB connector positions swapped)
Uses the Cmedia CM119B or CM108B USB audio IC
Uses a NiceRF SA818 UHF or VHF embedded radio module
500 to 1000(default) milliwatts RF output power
Small, portable with self contained radio and antenna
Radio settings changed using a program running on the Raspberry Pi
Required Hardware:
1.A fully assembled SHARI Pi3U, Pi3V, Pi4U or Pi4V.
2.A Raspberry Pi 2, Pi 3 or Pi4 . The Pi2 or Pi3 is normally used with the SHARI Pi3(U) ,while the Pi4 is normally used with the SHARI Pi4(U)
3.A case for the Raspberry Pi. A metal case is preferred but if you want to use a WiFi connection instead of a wired network connection then a plastic case may be required to obtain adequate range.
4.A micro SD card – 16GB or larger, Class 10 or better is recommended.
5.A power supply for the Pi-This should be a power supply intended for the version of the Raspberry Pi. These supplies typically provide 5.1 to 5.2 VDC to the Pi. Current requirements vary with version. Numerous problems with Allstar Nodes have been traced to inadequate power supplies.
