Number of downloads: 35For Southern Johor area, as Mux 2 moves from 698Mhz to 650Mhz (as shown on updated frequency list); it shall no longer interfering with Indonesia's SCTV. Sounds beneficial to both countries.
But when Mux 2 uses 650MHz, it will cause interference to another Indonesia's analogue TV station, RCTI (647.25MHz).
Solve one problem, then create one new problem. 
And MYTV still decides to go on for now.
There's no date on when would restacking works would happen for areas other than Langkawi, so things might change in the future...
When that happens, let's see the JB viewer's response whether the RCTI's analogue signals would be strong enough to disrupt Malaysia DTT's Mux 2 signals or not.
Anyhow, just hope that the restacking works would improve the overall DTT coverage and reliability for Langkawi.
If you're not in Langkawi, then just wait la.
