4663 kHz dash/chirp
« on: June 11, 2023, 2015 UTC »
I'm hearing a rough chirp beacon/marker  at 4553 kHz (USB). This repeats approximately on a 4 sec period. There's a slight descent in th enote, which is also wavery/fluttery. Additionally, the starting pitch seems to vary a little.  Peaking arounf S5 received on the random wire dipole.

Interesting

All I can get is an ocean wave height radar, both locally and on the KFS kiwi SDR.

Where are you receiving the signal at?

Sorry, was slow to get back to this.  I heard the signal from the SF Peninsula, near Stanford University. 

Not heard again since my initial report - listening opportunities coincided with poor conditions.
