Two clarifications and a question re:

After doing a quick-n-dirty audio job, I've determined that it's a
solid 3KHz sine wave. After a little research, I found that WYFR
transmits on 5950KHz, so the frequency of the tone makes some sense.
That said, *why* am I hearing this in the first place? When WWCR and
V02a butt heads, all I hear is the overlapping crosstalk; with SK01
and WYFR, it's as they're doing a cheap and irritating Emergency
Broadcast System imitation. If anyone could shed some light on this
curiosity, I'd appreciate it.
> [09:11Z, 09:16Z, 09:22Z, 09:26Z] Possible SK01 Tx
I see faint traces of SK01 transmissions in the spectrogram beginning
at 08:59:50Z, 09:04:50Z, 09:09:50Z, 09:14:50Z, 09:19:51Z, and
09:24:51Z. What I probably heard was the closer/footer tone of RDFT
instead of the header tone.
