EDABv2+ DAB+ digital radio exciter

Description

DAB+ IS FINALLY AVAILABLE ALSO FOR SMALL RADIO STATIONS AND LPFM – HOBBY USERS

Based on stand-alone solution which receives ETI stream via Ethernet. This stream can be from Internet/Ethernet sources or created by you.

SPECIFICATIONS:
– Nominal Transmit Frequency: 176 … 239 MHz
– Maximal Transmit Frequency: 400 MHz (with 1Ghz reference clock)
– Transmit Power: approximately -60 … 15 dBm
– Signal shoulders height: 54 dB (if TX power is 3 dBm).
– Drivers Installation Needed: NO
– Software Needed: NO (Only if you need to create ETI-stream yourselves, ODR-DabMUX is needed)
– LEDs That shows state: Yes (underflow, PLL-lock, link activity, FPGA status)
– I/Q samples width: 18 bit
– Complex sample rate: 6144 kS/s.
– Input interface: 10/100 Mbit Ethernet
– External power: 5V / 1A (power consumption – is up to 700mA in old PCB versions, and up to 450mA in new one’s)
– Output RF connector: SMA-Female

This card is capable of creating DAB+ signal without a need of a directly connected nearby PC computer. All CPU-intensive jobs: ETI-processing, adding error correction codes, adding phase reference, DQPSK, Fourier transform/COFDM and I/Q processing are done by the card itself (FPGA). All that is needed is a ETI stream from the satellite provider or from software such as ODR-DabMux sent by the Ethernet to the board. Just set network parameters, point to the source of ETI-stream (IP and port), and set RF frequency and amplitude – and voila! A version of this card also supports SFN (several transmitters working on the same frequency) by means of different firmware and some hardware mods.

Important:
Requires ETI stream (computer running ODR-DabMUX somewhere connected to Internet or Ethernet). The audio is fed to this computer and it is this computer that creates the ETI stream. This computer can be anywhere connected to Internet, even on the other side of the world thousands of km far from DAB+ card.

How do I setup DAB+ radio?
Step-by-step instructions are here: https://wiki.opendigitalradio.org/RaspDA

FIRST POWER UP
– Connect antenna to DAB+ exciter board
– Connect Ethernet cable
– Connect +5V power supply
– If your network has gateway of 198.168.1.1 than the card will start transmitting stream from test source in Belgium. If not you will have to change settings.
– The IP of card is set to: 192.168.1.170 and network Gateway is et to 192.168.1.1. If your network setup differs you won’t be able to open config page, adjust your Ethernet adapter card gateway to 192.168.1.1. and you will be able to open card settings in web browser at: 192.168.1.170. Username and password are admin/admin.
– Read the manual for more info, it is available under Additional information tab above.

WHAT IS DIFFERENT WITH THE SFN REVISION OF DAB+ COMBO PACKAGE?
– The card is equipped with a few hardware modifications and is superior to standard card. You can use it also when you don’t want to use the SFN function.
– With correct version of firmware both on the card and ODR-DabMUX it is possible to run in SFM mode.
