Every year, the Maritime Radio Historical Society celebrates the closing of the last commercial Morse code radio station, which happened at 0001 UTC, July 13, 1999. They do this by re-manning the watch for a few hours in honor of all those who so diligently listened for distress signals on 500 KHz and other frequencies continuously for over 90 years. Your humble author was one of those, who in the late 1980’s and early 1990’s strained to hear, through the static crashes and OTHR, the simple, yet effective combination of SOS sent in Morse code.
Fortunately, after the closure of KPH, the National Parks Service took over the land and preserved the buildings and antenna fields intact. Today, a dedicated group of volunteers maintain these facilities as a working museum. This is the earliest history of radio technology and from this, sprang Amateur Radio, then Broadcast Radio services.
So, if you have the opportunity on July 12 (Sunday, starting at 8 pm, EDT), tune around to some of the frequencies listed below and see how ship to shore communications was handled:
|426||426||488||472||448||425, 454, 468,480,512|
These are duplex frequencies, meaning; the ship transmits on one frequency and listens on to the shore station on another and vice versa.
Those medium frequencies do not carry that far during daylight, however the high frequencies should be heard across the world.
In addition to that, there are youtube videos to watch:
There are more videos on youtube, if one is so inclined.
Those old RCA transmitter look like they are in excellent condition. Somebody has spent a lot of time restoring those units.
Hopefully, one of these years, I will get a chance to head out to San Fransisco during the middle of July and see this in person. It would be nice for my children to see what their old man used to do in what seems like a different lifetime.
