UNID Tones 6920 USB/AM 2016 UTC 31 Oct 2023
« on: October 31, 2023, 2021 UTC »
Heard these very loud and clear via the NA5B SDR near Washington, D.C.

2016 UTC: Tones on, then silence.
2020 UTC: Two transmissions of tones with silence in between.
2022 UTC: Another transmission tone -- it's a very wide signal.
