M...Sushi,

Now Hearing the Same Sweeping "CoDar" Like Sounds
around 5230 kHz and extending from 5215 kHz with a
Sharp Chirp to 5250 kHz also with Sharp Chirp @ 09:00 UTC
- - - Strongest Sound and Signal indication near 5235 kHz
S-Meter : S3.5 ~ S8 Peak [Grundig Satellit 800 Radio]

NOTE - Using the Icom IC-R75 Receiver in the "FM" Mode
generally confirms some sort of a Frequency Sweep Signal
across 35 kHz versus Broad Band Signal Overload.

Thanks for the wiki. Now I know where Twain Harte is located. You
probably get better SW reception than I do since your noise floor is
lower.

Yeah, these codar signals are quite wide. Certainly wider than my
widest filter (9kHz).
