Title: 2135 UTC 29250 FM repetitive chirp
Post by: chanito on May 30, 2021, 2139 UTC

a very brief chirp, sounds almost like packet, but not. Repeats on a 15 second cycle. Transmission is maybe .25 seconds. Signal is not steady. Sometimes it fades off for a couple cycles then comes back strong again. S3 is about the highest.
