FS#9420 - FM tuner reception fades over time

I have experienced a fade in reception with my sansa e260. If I tune to a station, the longer I listen, the more static becomes present until the station is all static. I have found however that if I navigate to another station and go back. The station is clear again. This does not happen on the original firmware and does not seem to be location specific.

So the firmware seems to be seeing a degrading signal, but the signal is not actually degrading. Or perhaps the frequency to which the FM tuner is tuned, begins to deviate until it reaches a point of all static, even though the tuner still displays the original frequency.

Thanks.

I’ve experienced the same with my c250. I so rarely use the radio (as in, it’s been months) I never tried to track it down or do anything about it...

sounds like the tuner frequency drifts... Does this also happen in the original firmware?

I can confirm this experience on my e280 and it appears to be related to the temperature of the unit. If the temperature of the unit is changing - such as warming up in your hand or pocket - the FM reception will noticeably reduce but can be rectified by reselecting the desired frequency/station. In comparison leaving it running on a desk for many hours does not appear to have any problems.

To address Peter’s question, I do recall this happening in the original firmware, but it was less noticable due to the differences in radio quality between the rockbox and OF (I raised this as a possible bug in FS#10405)
