Hi,
I recently acquired a Chirpsounder Receiver, BR Communications Model 
RCS-5B from a US Consulate surplus sale.  It came with all Operation, 
Service, and Parts manuals but not with the "key" document for it's use, 
the transmit site list.
Briefly, there are a number of Chirpsounder transmit sites around the 
world that transmit an omnidirectional frequency swept signal at 50 or 
100 kHz/Sec from 2 to 16 or 2 to 30 MHz.  Receiver sites use the 
Chirpsounder receiver to track the swept signal, display the resultant  
frequency vs. signal strength display, and on a CRT, signatures 
indicating groundwave, single hop, and multi hop propagation.  By 
interpreting the display the user can determine optimum frequencies for 
communication with the area where the transmitters are located.  I 
wanted the receiver for contesting when I return to the USA where I CAN 
use amateur radio :-)  Pretty great toy for a Ham, right?
Problem is, each transmitter sites begin their sweep at a very precise 
time and frequency.  In order to use the receiver you must have a list 
of the sites, and their start frequency and time.  This I do NOT have 
and without it I have just another boat anchor :-)
I do not have Web access here in KSA so I can't do a search.  If one of 
you would be so kind as to check the various search facilities for 
"Chirpsound" and "Chirpsounder" to see if there is a source for the 
"Site List" I would sure appreciate it.  Perhaps a search for NAVCOMMSTA 
might be helpful too.  It is the only transmitting station named in the 
manual but the time/freq data is not included.  
Many thanx in advance for your assistance.
