A google on it shows 24.8 kHz. In the 1960s, the last time i lissened,
they were sending cw at 20 wpm and the callsign was NPG/NLK,
which means NPG San Francisco keying  NLK at Jim Creek.  I recall
the Puget Sound Antque Radio Club, at their meeting place and 
museum at NE 175 St. in Seattle, had, maybe still has, a model of the
Jim Creek station that somebody made up. I recall it showed a 
transmitter building as well as a generator house, so i'm not sure
about Jim Creek's dealings, if any, with the power company. I recall
when last in WA maybe a dozen years ago tuning an FSM across the
24 kHz frequency and watching the signal level meter needle go way
up. I swear, i have also heard the characteristic warble of TTY on some
phone lines up in that area ( but i may be wrong about sourcel )
The "very slow speed FSK" as in "VERY" i believe applies to the
50 Hz and such ELF station in Michigan, now scrapped, and not the
VLF tty such as Jim Creek.  -Hue Miller
