Sierra Radio has partnered with Pignology to develop a new generation of station
Our combined solution provides remote rig control, streaming audio, station monitoring
The user can operate the station around the house or around the world from a Windows
PC, Mac, iOS or Android device.
Pignology supplies the rig control and audio streaming system.
Sierra Radio supplies the station controller and accessories.
Station Controller The Station Controller can monitor… - DC voltage input - Switched DC voltage out - DC current - Temperature - RF power forward and reflected using an Elecraft directional coupler - 2 user definable opto-isolated digital inputs - 2 user definable 0-30 VDC analog voltage inputs The Station Controller can control… - Primary station DC power (10A, 20A or 30A latching relay options) - AC power (up to 15A) with optional external AC power switch tail - 3 user definable SPDT 2A small signal relays Additional features - 9 front panel LEDs to indicate system status - Audio tone generator and built-in speaker for status and alerts - 10 pin HamStack LCD jack for optional LCD panel - Firmware supports complex tone and CW generation RadioRouter The Radio Router is an active receive audio mixer and optional dry contact switching sub-system for transmitter switching. The RadioRouter comes in various configurations supporting from 4 to 8 receivers and optionally 2 or 4 transmitters. The receiver mixer takes speaker output or line level audio, does DC isolation, buffering and gates the audio before going to an audio summing amp, then is amplified by the built-in 10w speaker amp. Each audio channel can be manually switched or controlled through the RS232, RS485 or USB serial port. The RadioRouter is controlled by a PC running our RadioRouter control software. You can also use our Universal Control Head or a device of your own design to control the mixer through the serial port. The optional transmitter control board provides 14 dry contacts to switch mic audio, paddle, key, PTT, ALC or just about any signal up to 2 amps between multiple radios and a common IO port that connects to the main microphone, paddle, key etc. The supplied firmware supports the OTRSP (Open Two Radio Switching Protocol) serial command set used by many contesting programs. Remote Coax Relay The remote RF coaxial relay provides a single pole / double throw RF switch capable of handling up to 200 watts will very lo insertion loss. The remote coax relay includes an on-board microcontroller and SRS device control network connection which provides power and control data over common CAT5 cable. Sierra Radio Embedded Linux Host Computer The SRS Linux computer is a low power embedded system for remote communications and control of equipment using the SRS Device Control Network (DCN). Based on the CircuitCof BeagleBone CPU board with options customized for building ham radio projects including an audio CODEC, HamStack board socket, multiple serial interfaces, Xbee RF data radio interfaces and general purpose digital and analog IO. The motherboard is designed to stack on top or below the SRS Station Controller chassis box. DCN Extender Extend the range of the SRS Device Control Network The data network connects 2 or more devices connected by an RF data link and sends serial command from device to device. Each node automatically routes messages from one node to another to ensure that messages on the network are received by all nodes. Mesh networks have the advantage of being easy to implement, extend and automatically self heal. The range extender can be used with the Station Controller, CommBridge, digital compass, and other SRS products. DCN CommBridge The CommBridge connects one RS232 port, 1 RF Xbee DCN connection and 2 wired DCN connections. All signals are actively connected. Network traffic entering on any port is routed to the two ports. The CommBridge includes a power injector that applies the external 12 VDC to the wired (CAT5) DCN cable. Digital Compass System The StationStack Digital Compass can tell you where your antenna is REALLY pointing within 2 degrees. It does this using a highly accurate 2 axis digital magnetometer. The compass box is mounted to the boom of your yagi or other directional antenna and sends the actual direction back to your radio shack using a wireless RF data transmitter or through a hard-wired network connection. The antenna direction is displayed on your PC using our digital compass display program. The data is also available through a RS232, RS485 or USB connection if you want to easily integrate the digital compass into your custom station. Universal Control Head The control head provides 12 high quality 3 color LED illuminated push buttons, a rotary encoder and a 2 line x 16 character LCD display. The control heads communicates to a PC, HamStack controller, RadioRouter or other devices running RS485 over a common ethernet cable. An optional converter box changes the RS485 to RS232. The Universal Control Head includes a PC program that allows the user to configure the behavior of the control head. The simple configuration program assigns command strings that are transmitted when buttons are pressed or the encoder is rotated. You can set any arbitrary serial string to be transmitted. We also have a Station Control Panel software program that emulates the behavior of the hardware control head. The software version, runs under Windows and is fully user programmable. TR Sequencer The purpose of TR sequencer is to turn station equipment on and off in a specific order with a specific amount of delay time between each switched event. This has been a requirement for decades, since it is the only "sure way" to keep form accidently damaging equipment such as "hot switching" RF or power relays, transmitting into receive preamps, transmitting into feedline with no load, etc. Making shure each event happens in the proper order and with the right delay time is an absolute must at any station using preamplifiers, amplifiers, changeover relays, or in a high performance contest environment. Just about any ham station can take advantage of using a TR sequencer. This is true
