Subject: KSM PW-15 Transmitter on YouTube!

Those who were monitoring the KSM 12Mc signal on Saturday were 
hearing the historic Press Wireless PW-15 transmitter the Maritime 
Radio Historical Society (MRHS) has restored to operation.  There's 
quite a bit of history attached to this transmitter.

Built in the 1940s, it was used during WWII by Press Wireless to 
transmit press reports across the Pacific and around the world.  When 
Press Wireless was absorbed by Globe Wireless, the transmitter was 
installed at the Globe transmitter site in Palo Alto, CA.  After the 
era of point to point press broadcasts ended, the PW-15 was used as a 
Morse code transmitter in the marine service for station KFS, talking 
to ships at sea.

Volunteers from the MRHS recovered the transmitter from the Palo Alto 
site and installed it (along with another PW-15) at the transmitter 
site for ex-RCA coast station KPH in Bolinas, CA.  It was restored to 
full operation as the 12.993Mc transmitter for KSM, the station 
operated by the MRHS.  It is believed to be the only PW-15 
transmitter still in operation.

In the YouTube video you will see Steve Hawes, Senior MRHS 
Transmitter Engineer, bring the big transmitter to life.  Watch as he 
confirms the frequency of transmission, turns on the primary power, 
engages the high voltage power supply and sends a test 
transmission.  A cameo appearance is made by our very own QSL 
Mistress, Ms. Denice Stoops.  See the video at:

At YouTube you'll be able to subscribe to our "channel" for future 
videos (but I'll announce them here too).

The primary thing we're interested in is to find out whether you 
enjoy videos like this showing our operations.  Please let me know
