The Maritime Radio Historical Society is dedicated to the preservation and documentation of the history of maritime radio communications with special emphasis on the stations and companies of the Pacific coast of the United States. The call sign of the amateur station of the Society, K6KPH, is intended as a tribute the greatest of those stations, the "wireless giant of the Pacific", KPH.
K6KPH on-the-air operations use only the original transmitters, receivers and antennas of KPH. No amateur equipment is employed. At this writing K6KPH operating frequencies are 3550, 7050, 14050 18097.5 and 21050kc. The transmitters for most of these frequencies are Henry HF-5000 commercial transmitters. But for special occasions the 1950s vintage RCA commercial units known as "K" and "L" sets are used.
The transmitting antennas are double extended Zepps for frequencies below 12Mc and H over 2 for 12Mc and above. All antennas are fed with open wire line.
K6KPH usually guards 7050.0, 14050.0, 18097.5 and 21050kc when KSM is on the air. Give a call! The best bet is to use commercial calling procedure since the amateur frequencies are scanned along with the ship calling frequencies. Call "K6KPH" repeatedly (within the bounds of identification requirements of course). When the K6KPH operator hears you he will send "DE" after which you can send your call and list your traffic.
We usually have multiple operators on duty.
K6KPH is also activated for special occasions such as International Marconi Day in April and for Straight Key Night on New Year's Eve. Don't let anyone tell you that radio operators don't know how to party!
The KPH receiving station is 18 miles north of Bolinas on the Pt. Reyes peninsula. The operators work from this location, keying the transmitters in Bolinas remotely, just as was done when the station was in daily service.
KPH is activated at least once a year for the "Night of Nights" event that commemorates the last commercial Morse transmission in the US on 12 July 1999. KPH operates on HF frequencies in the 4, 6, 8, 12, 16 and 22Mc marine bands and on 500 and 426kc in the MF band.
The Maritime Radio Historical Society's own coast station, KSM, is usually on the air on Saturdays beginning at 1900z. Our Morse frequencies are: 426, 500, 4350.5, 6474.0, 8438.3 12993.0, 16914.0 and 22445.8kc.
We also send press and weather by RTTY in Baudot and FEC on 6328.0, 8433.0 and 12631.0kc.
You are welcome to join us any Saturday.
There are actually two sites involved. The transmit site is open from 0900 to 1700 Pacific time. The receive site is open from 1200 to 1700 Pacific time,
We start our day at the transmitter site in Bolinas (451 Mesa Road) at 0900 for Services of the Church of the Continuous Wave where pastry and coffee are served. I suspect that the Transmitter Department would insist on putting on one of their famous Shock & Awe vintage transmitter demonstrations in your honor. Press broadcasts begin at 1000.
The members of the Operations Department usually depart at about 1100 to activate KSM and K6KPH at the receiving station at Point Reyes (17400 Sir Francis Drake Blvd) but the transmitting staff remains at Bolinas.
You would be welcome to join us at either or both locations.
