説明
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:
– 公称送信周波数: 176 … 239 Mhz
– Maximal Tramsmit Frequency: 400 MHz (with 1Ghz reference clock)
– Transmit Power: approximately -60 … 15 dBm
– 信号肩の高さ: 54 dB (TX 電力が 3 dBm の場合)。
– Drivers Installation Needed: NO
– Software Needed: NO (Only if you need to create ETI-stream yourselve, ODR-DabMUX is needed)
– LEDs That shows state: Yes (underflow, PLL-lock, link activity, fpga status)
– I/Q サンプル幅: 18 ビット
– 複素サンプルレート: 6144 kS/s。
– 入力インターフェース: 10/100 Mbit イーサネット
– 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
The main point of creating this hardware – is to have possibility to create DAB stream without need of PC. So all CPU-intensive job, like: ETI-processing, Adding error correction codes, Adding Phase Reference, DQPSK, Fourier transform/COFDM and I/Q processing has been moved from the software to hardware part (into XC6SLX9 FPGA). After this changes been done, all what is needed – is ETI stream from the satellite provider or from ODR-DabMux sent by the TCP-connection to the board. Just set network parameters, point to the source of ETI-stream (ip and port), and set RF frequency and amplitude – and volia! There is also exciter info that describes how to enables SFN operationing by using various GPS
重要：
ETI ストリームが必要です (コンピュータが実行されている) ODR-DabMUX インターネットまたはイーサネットに接続された場所）。オーディオはこのコンピュータに供給され、ETI ストリームを作成するのはこのコンピュータです。このコンピュータは、DAB+ カードから数千 km 離れた地球の反対側であっても、どこにいてもインターネットに接続できます。
DAB+ 無線をセットアップするにはどうすればよいですか?:
詳しい手順は次のとおりです。 https://wiki.opendigitalradio.org/RaspDA
エキサイター自体は WEB インターフェイス経由で設定されます (Web ブラウザに DAB+ エキサイターの IP アドレスを入力します)。
Output level:
It is low, you will need an amplifier. Check ここ と ここ for solutions.
何が含まれていますか?
– DAB+ exciter board, new version (blue PCB)
– External GPS receiver with cable (for better accuracy)
– Power supply 5V 1A (EURO plug, 90-264V universal)
– Cool custom made small aluminum box
他に何が必要ですが、含まれていませんか?
– Output level is is very low, you will need an amplifier. Check ここ と ここ for solutions.
– An antenna, one of these is recommended:
– Coaxial cable such a これ また これ.
– ETI source. If you don’t have it you can use ODR-DabMUX (It may sound scary but you can handle it)
– Ethernet cable and access to local network or Internet with active ETI source
– 音楽のセンスが良く、リスナーを魅了するプログラムを組み立てる優れたスキル
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.
