02:43 UTC - Picking up a series of chirps transmitted at approx 4 second intervals on 11150.0 kHz. The composition of the signal is 3 x pips (carrier) for each sounding.

The chirps are also simultaneously transmitted on 6846.4 kHz and 6803.4 kHz.

This transmission is identical the ones I previously reported on this thread: UNID chirps 6845.0 kHz 0130 UTC 03 JUNE 2021

23:54 UTC 22 JULY 2021 - UNID chirps are currently active. Nice strong signal tonight;
00:28 UTC - Appear to be getting double chirps tonight on this frequency (1 chirp followed by a double ping chirp).
01:05 UTC 23 JULY 2021 - Found the matching mate on 11025.0 kHz. As with the pair located on 6803.4 kHz and 6846.4 kHz, we now have a matching pair on 11025.0 kHz and 11150.0 kHz;
02:00 UTC - UNID is still chirping strong with nice strong signal.
