[QUOTE="mm1352000, post: 997367, member: 82144"] The range for FM radio scanning is roughly 20 MHz. It would be really unusual for stations to be 10 MHz out. Maybe 0.1 MHz, or 0.2 MHz... but not 10 MHz. So I'd appreciate a confirmation from the OP... In direct response to your comment... The scanning code is not buggy. The issue is (1) that many tuners are very sensitive and (2) that the BDA/WDM interface specifies only a lock/no-lock flag for analog tuning (ie. no concept of signal strength/quality). It is bad enough that the tuners report signal lock 0.2 or even 0.3 MHz from the centre frequency of a channel. Worse is that TV Server can't use signal quality/strength to hone in on the real centre frequency. In order to avoid creating duplicate channels the radio scanner jumps something like 0.3 or 0.4 MHz after a station is locked. This will never really be entirely satisfactory but we're not able to solve interface and driver limitations. [/QUOTE]
