streaming radio gap s

Streaming audio services, Streaming media services

there is a reception gap when I listen to WUSF radio on my computer. It is unusual in that it occurs with no loss in the information,eg, the sentence is stopped without loss of continuity. The average gaps are just about 25 minutes apart, +/- approx. 2 min. The gap duration is about 13 +/-
5 sec.

Sounds like your computer may be busy with other tasks and is buffering the information during the gap periods and the information is available when processing time becomes available.
