[GreenKeys] Fwd: MRHS at Pacificon!

Fri Sep 16 22:44:49 EDT 2011

The organizers of Pacificon, the annual west coast amateur radio event  
(October 14, 15, & 16, Marriott Santa Clara, Santa Clara, California),  
have generously invited the Maritime Radio Historical Society (MRHS)  
to participate this year. We look forward to being at this event and  
meeting folks who have followed our project as well as those who are  
unfamiliar with our activities.

Here's what we'll be up to at Pacificon:

o PRESENTATION (Saturday at 1100 in Salon B) - Richard Dillman,  
president of the MRHS and Chief Operator of stations KSM and K6KPH,  
will give a slide show and talk about the history of the stations we  
have restored to operation. The photo-rich presentation will present  
the story from the time of "Bolinas high power" operated by the  
American Marconi Company in 1914 to current day operations.  Questions  
are encouraged!  Not to be missed.

o DEMONSTRATION (Main Hallway, Saturday 8am to 5pm, Sunday 8am to  
12pm) - Mem! bers of the MRHS Transmitter and Operations Departments  
will operate stations KSM and K6KPH from Pacificon. Using a control  
console built by Transmitter Supervisor Steve Hawes we will remotely  
key the original KPH transmitters in Bolinas.

We plan to have coast station KSM operational on MF (426kc and 500kc)  
as well as HF (probably 12993kc) using Morse code. The power level on  
all frequencies will be about 5kW. Watch will be kept on 500kc and ITU  
channel 3 in the HF band being used for calls from ships.  The "wheel"  
and KSM traffic list will be sent (see below).

Holders of a commercial radiotelegraph license of any class will have  
the opportunity to key KSM and have their licenses endorsed to that  
effect.

Amateur station K6KPH will also be operated by remote control, keying  
KPH transmitters in Bolinas shifted to amateur frequencies and  
throttled back to 1.5kW. Anyone with the ability to use Morse code may  
operate K6KPH, no license required. K! 6KPH will use a single  
frequency at a time, probably 14050kc. However we will have the  
capability to shift to other transmitters as well.

The transmitting antennas for KSM and K6KPH HF may be H over 2 or  
double extended Zepps, depending on frequency. The MF transmitting  
antenna will be a Marconi T.

Receiving for KSM and K6KPH will be done at Pacificon using a roof-top  
dipole for HF (commercial and amateur) and a shielded loop for MF. The  
receivers are anticipated to include a RCA AR-88LF, Marconi Atalanta  
and HRO-5T. Other receivers may be used as well.

We hope to have auxiliary equipment in operation including a Boehme  
paper tape keying head (to send the "wheel" and traffic list for KSM),  
a Kleinschmidt paper tape perforator, one or two "mills" (radio  
typewriters) and of course a station clock marked with the silent  
periods.

There will also be a photo display showing the history of the stations.

MRHS members will be on hand to answer questions and demonstrate  
equipment. Please stop by and say howdy!
