K6KPH, the amateur station of the Maritime Radio Historical Society, will be on the air for this year's International Marconi Day on Saturday 30 April.
K6KPH will use the transmitters of ex-Marconi, ex-RCA coast station KPH at the 1913 Marconi site in Bolinas, California. Operators will be at the 1929 ex-RCA receive site at Point Reyes, California.
Several volunteer operators, will be manning the K6KPH operating positions. Among these will be ace operator Rick Wahl, ex-NMC, ex-KPH.
Hours of operation:
1700 - 2359GMT
Frequencies:
3550.0
7050.0
14050.0
21050.0
Transmitters will be Henry commercial HF5000D units except for 7050.0 which will be using a 1950s vintage RCA transmitter. TPO for all transmitters will be 1.5kW.
Visitors are welcome. The receive site is located at 17400 Sir Francis Drake Blvd., Inverness, California (the station is actually well past Inverness but that's the town name that works with most on-line mapping programs).
Coast station KSM will also be on the air with the usual press and weather service on all Morse and RTTY frequencies.

International Marconi Day is April 30!
This year's International Marconi Day is Saturday, April 30, beginning at 0000 UTC and going until 2359. Details are at http://www.gb4imd.org.uk/ .
IMD is held annually on the Saturday closest to the birthday of Guglielmo Marconi. It provides an opportunity for amateurs around the world to make point-to-point direct contact with historic Marconi sites. An award is given for working these.
Stations operate on or near these sites. These are all around the world. Here's the organizers' list (not all are confirmed):

Google Earth Pt. Reyes Tour Ends
What you want to do now is zoom Google Earth out to a high altitude. 50 miles should do it. This puts you in space, and you qualify for astronaut wings, but that's not relevant here.
Get Point Reyes in the middle of the screen so you can see it all. Notice the large line etched in the ground in such a manner as to separate the point from the land to its east. This line starts down south around Bolinas and Stinson Beach at 37 degrees 54 minutes 23 seconds North Latitude by 122 40 33 West Longitude. It heads out to sea on the north end of Tomales Bay, at about 38 degrees 14 minutes 46 seconds North by 122 59 01 West.
This is California's notorious San Andreas Fault. Point Reyes National Seashore is on a plate tectonic boundary, and the motion on this long strike-slip fault will eventually break it away from the rest of California, creating an island. Tomales Bay is where this has already happened.
While of course this is a geologic process requiring millions of years, about 20 feet of this motion happened all at once on a stretch from here clear to Cape Mendocino. This event is better known as the great San Francisco earthquake of 1906.
Now go part way up Tomales Bay to a spot on its east shore:
38° 8'39.22"N 122°52'40.99"W
This puts you in a rather picturesque shoreside complex with one big old building and several smaller cottages. This is the Marshall receiving station originally built by Marconi after the earthquake destroyed the original KPH in the Palace Hotel down in San Francisco.
As with other Marconi Hotels in the world, the Marconi company created a very attractive and comfortable, not to mention highly self-sufficient complex where the staff lived. This was necessary, given the remote locations of the stations. To the left of the main hotel with its veranda, were cottages for the station manager and chief engineer.
Various white objects in the large clearings to the north and east suggest possible former antenna locations. Some equipment remains on exhibit at the site, and I believe there may still be landlines in existence enabling remote operation of KPH from there.
When Marconi Wireless left the United States not altogether voluntarily after World War I, the subsequent Radio Corporation of America (RCA) owned the property. KPH did not move until after World War II. RCA eventually sold to a series of other owners, including the Synanon program. It was ultimately confiscated by the IRS, and then abandoned. Now it is park service property. It is being restored, and made available as a conference center.
The transmitters were in the old "power house" at the Bolinas facility, which we've already looked at.
Marshall is the VERY small town to the north, on the little inlet and former marina type thing called Marconi Cove. I believe it's all ranch land now. There's really not much in the way of habitation at all.

Special Maritime Radio Historical Society Event 11/21-22
From MRHS:
On 21/22 November the MRHS will activate KPH and K6KPH from the original trans-Pacific receive site of the American Marconi Co in Marshall, CA. This was also the receive site for KPH before WWII. KPH will be active on 426kc, 500kc and on 4Mc and/or 6Mc HF (exact frequencies to be announced). K6KPH will be on 3550kc and 7050kc. Transmitters in Bolinas will be keyed remotely from the Marshall site. KPH was closed at the beginning of WWII so this activation will recall the days before Pearl Harbor.
As a special treat SS JEREMIAH O'BRIEN/KXCH (Denice Stoops at the key) and SS RED OAK VICTORY/KYVM (Steve Hawes at the key) will attempt to be on the air on MF.
If you have the ability to relay traffic to the National Traffic System we'd love to hear from you if you're within range of K6KPH during the day on 3.5Mc or 7Mc. We will be soliciting traffic from those attending this event and may have a lot on the hook. So if you can be QRV for us please let me know.

International Marconi Day is April 26
International Marconi Day is a yearly amateur operating event also of some interest to utility listeners. This year, it lasts from 0000 UTC on 26 April 2008 (afternoon of the 25th in the US) to 2359 UTC, 26 April 2008.
It is organized by an amateur radio club near where Marconi transmitted his historic transatlantic signals. The home page is at http://www.gb4imd.org.uk/
.
K6KPH, the amateur radio station of the Maritime Radio Historical Society at the historic KPH "Power House" on Pt. Reyes, CA, will be active starting at noon Pacific time, 1900 UTC, on Saturday, the 26th. Frequencies are 3550, 7050, 14050 and 21050 kHz.
As always, QSL to:
