@jgkoomey @steveyaeger There were actually three HF receiver sites at Point Reyes. There was the AT&T radiotelephone station KMI (which was completely razed about 10 years ago), which was next door to the still-alive-and-kicking RCA radiotelegraph station KPH (worth a visit when open). And up the road a bit is the still-active (but remotely controlled) Coast Guard station NMC.
KMI had this spiffy sign, which I'm told was saved and is in storage somewhere.

KPH still lives on Saturday afternoons. I copy their CW, RTTY, & SITOR transmissions from as far away as the East China Sea on my ship. They also activate K6KPH on the amateur bands. https://www.radiomarine.org/
