前兩日，22-Nov-2015 svxlink 發表一個很重要的更新，版本15.11。
是次更新，終於加進支援 SDR !!! 今後，svxlink 可起用 RTL2832U 手指作為接收端，並支援多支手指 (即多條頻道)。這更利於將 svxlink 用於中繼控制，尤以會將接收到的訊號 audio streaming 出去的應用。
兼容制式很廣，包括:
- FM
- nFM
- AM
- AM narrow
- USB
- LSB
- CW
- CW wide
- wFM (broadcast)
廉價的附出，更強的支援。
另 DTMF 解碼重寫，新的 decoder 只需 DTMF 訊號短至 40mS 就可成功解碼。
上月發表新的 Echolink 文章後，本以為再更新也應是兩年後的事。但 SDR 是我近年相當重視的 topic。我希望於 2016 上半年會一會這個 Svxlink + SDR 方案。
*****************************************
EngLish:
SvxLink release 15.11 on 22-Nov-2015, which is an important update that support SDR, Yes !
SvxLink ver 15.11 support RTL2832U USB dongle, as well as multi-devices (it means multi channels). The solution is cheap but powerful, especially use SvxLink as a reapter controller and audio streaming via network connection.
It supports:
- FM
- nFM
- AM
- AM narrow
- USB
- LSB
- CW
- CW wide
- wFM (broadcast)
On the other hand, the DTMF decoder was rewritten. The DTMF signal can be decode as short as 40mS.
I hope I will test this soultion before 2016 Q2.
