6930 USB
2250z-2300z: Intermittent 3-dash tone ("O") until close to 2300z when other characters followed, but I couldn't copy 'em by ear.  Off or faded by 2305z.
For a few minutes around 2300z, some overlap with KTIT playing blues on 6930 USB.  CW signal off just as KTIT was picking up here, no QRM.
