The fix I have noticed is that auto scan now works correctly and only stores one set of multiplexes from a single transmitter. Is that it?
I posted this on another forum about changes I noted with the auto tuning on pre-1.02.28, 1.02.28 and 1.03.06 firmware:
I am in an area where I can pick up all multiplexes from Sutton Coldfield and Brierley Hill and selected multiplexes (at lower strength/quality) from two other transmitters. This used to cause chaos on pre 1.02.28 firmware as it would just store the first occurrence of that multiplex and shunt the repeats up into the 800's so you would end up with multiplexes tuned from 4 transmitters.
On 1.02.28 firmware it would ignore the two out of area transmitters but would still tune in both SC and BH. The region selection option would then only show West Midlands and selecting this would then give a mixture of multiplexes from SC and BH tuned in at the correct LCN's (none in the 800's). Not what you want for reliable recording.
Since moving to 1.03.06 it now also ignores the BH multiplexes and stores SC only so I no longer have to manually tune or remove and re-insert the aerial at the relevant points as it auto scans to avoid the BH multiplexes.
