I know they types and amounts of time vary on each piece of hardware. Plug and plays and OEM vehicle units allow for replays of a current station. The Lynx saves the last 8 hours of up to 25 presets. I'm a faithful SL2 user who is unsure which stations my unit can capture radio replays. I know 100 & 101 are restricted. I've resorted to experimentation with a few of my favorites like Hits 1, 70's on 7, 80's on 8, Velvet, Classic Rewind, BPM, Utopia and The Pulse with success. There are channels which I haven't picked up like Pop2k and NFL (probably restricted). After reading archived threads from different forums replays are picked up during the gaps in recording segments if a unit is tuned to that station. My question is which stations outside of 11, 12, 88, 100 and 101 are replays restricted? My other question is if the introduction time of a channels and the age of my refurbished SL2 is a factor? I could try and update the channel lineup via internet radio mode. It reloads the lineup every time I R & E and listen in the satellite mode. I'm not concerned with the last 60 minutes of live radio stored in the temporary replay buffer. Any and all replies are much appreciated.
