2 Controls and Connections
The front panel provides the first port of call to control your radio. Two version of the radio are
currently available:
A version with no local display: this can be used
with attached monitors for locally hosted client
software such as piHPSDR. It can be used
“headless” to connect to a PC client application
such as Thetis.
A version with a front panel 7” touchscreen
display, rotary controls and pushbuttons. A
touchscreen display provides a PC display from
the PC control application; rotary encoders and
pushbuttons provide access to the most
commonly used controls.
A different display version using the
“Andromeda” display is also planned. This
panel has more controls, and hands off
processing for them to an Arduino
microcontroller to reduce the load on the
Raspberry Pi.
2.1 Powering On and Off
The radio has a “soft” power button on the front panel. This is used both to turn power on, and to
turn it off again. It is important to shut the power down properly using this button: otherwise the file
system in your Raspberry Pi computer will become corrupted. The controls are different depending
on whether you have front panel controls or not.
2.1.1 Radios with front panel controls
To power the radio on: press and release the button. A short press is sufficient. The power LED will
illuminate.
To power the radio off:
1. Shut down the operating system. In PiHPSDR, click Menu and then Shutdown. You may also
click on the Raspberry Pi icon at top left on the screen; select Logout from the menu then
Logout on the Shutdown Options menu.
2. After the computer has completed shutting down, wait for approximately 10-15 seconds and
then press and hold the power button for around 3 seconds until the power switches off.
The front panel LED will go out.
2.1.2 Radios with no front panel controls
The procedure is slightly different as you may not have a computer display available.
To power the radio on: press and release the button. A short press is sufficient. The power LED will
illuminate RED.
