There is a free app at apple store called "可视收音机", from which you can listen to CR1 for horse racing. The signal of it is very smooth and not delayed (It seems that HKtool Bar is blocked and the app cannot receive radio signal anymore).

博士，我系成都网上收唔到，到出年年中搬屋后装个镬先至得，听朋友讲好像可以在香港家装个box将signal post 上internet 然后网上睇，不过我现在还没搞清楚，或春节回香港再研究。到时有新料再同大家share.
