SHARI (SA818 Ham Allstar Radio Interface) is a ham construction project that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. SHARI plugs into two USB jacks on a Raspberry Pi2, 3 or 4. There are 4 versions of SHARI:
- SHARI Pi3U (UHF for the Pi3)
- SHARI Pi3V (VHF for the Pi3
- SHARI Pi4U (UHF for the Pi4)
- SHARI Pi4V (VHF for the Pi4)
SHARI PiHat is a ham construction project that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. The PC board use a slightly modified PiHat form factor which plugs into the GPIO connector on a Raspberry Pi4 so the Allstar node is contained in a single enclosure. Options include:
- VHF (2 meters) or UHF (70 cm)
- External fan
SHARI PiHat (52PI Case) is a ham construction project that implements a Pi4B hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or a VHF (144-148 MHz) radio module. The radio module and interface circuits are located on a custom Raspberry Pi Hat board. This Pi Hat board plugs into the Pi4B using the 40 pin GPIO connector. A JST 2 conducter cable is used to complete a USB connection to the PI4B. This case includes an internal fan. The RF signal is routed to the antenna using a coax cable assembly to allow alternate antenna locations to be used. A complete Allstar node can be created with a SHARI PiHat 52PI Case kit, a Raspberry Pi4B (with power supply and microSD card) and an Allstar image.
SHARI PiHat (Unistorm Case) is a ham construction project that implements a Raspberry Pi hosted Allstar node using a NiceRF SA818 embedded UHF (420 – 450 MHz) or VHF (144-148 MHz) radio module. This case allows the use of a Raspberry Pi3 or Pi4 server. The PC board conforms to the PiHat form factor. It plugs into the GPIO connector on a Raspberry Pi so the Allstar node is contained in a single enclosure. Options include:
- VHF (2 meters) or UHF (70 cm)
- Raspberry Pi3 or Pi4
- External fan
- Straight or right-angle antenna
DINAH-USB A (DIN connector based Allstar interface for Hams) is a kit construction project that implements a radio interface to a Raspberry Pi running Allstar software. The male USB A connector on DINAH-USB A plugs into a USB jack on a Raspberry Pi. A standard 6 pin miniDIN cable connects DINAH to any radio with a 6 pin miniDIN packet interface (also called a data interface).
DINAH-USB C (DIN connector based Allstar interface for Hams) is a kit construction project that implements a radio interface to a Raspberry Pi running Allstar software. DINAH plugs into a USB jack on a Raspberry Pi using a USB-A to USB-C cable provided by the user. A standard 6 pin miniDIN cable connects DINAH to any radio with a 6 pin miniDIN packet interface (also called a data interface).
BRIAN (SM) (Baofeng BF-88S Radio Interface to the Allstar Network) is a kit construction project that implements a Raspberry Pi hosted Allstar node using the circuit board and other parts from a Baofeng BF-888S as the node radio operating in the amateur UHF (70 cm) band. BRIAN connects to a Raspberry Pi using a short USB cable.
PAUL (Packet and Allstar Universal Link) is a kit construction project that implements a radio interface to a Raspberry Pi running Allstar software. PAUL plugs into a USB jack on a Raspberry Pi using a USB A to Mini B cable. A standard DE9 connector (9 pin dsub) with typical TNC pinout is used for I/O to the radio. COS and PTT utilize optically coupled solid state relays.
SHARI PiHat Mod2 board only is the board we use in our SHARI PiHat Unistorm kit. We sell the board only option for experimentors who would like to build a custom node using their own case, Pi, power supply and antenna.
The board allows the user to choose between an edge mounted or vertical SMA connector. It also has a U.FL jack (J3)which can be used with a builder supplied coax/SMA cable. A fan option is also available
