Dear Sir:- While on watch last night, Oct. 16th -17th, I was listening to Chicago (Go) and Milwaukee (Mk) working together and was fishing for Manitowoc Wis. (MW) whom I know to be working and I heard the following calls--"CB," "CN," "CU," & "CR." I also heard one which I took for "CS," but which sounded considerably like "St." He was working with "CB." All of these calls came in way clear and easily readable, without strain except for very heavy static. Should judge the wave length as somewhere about 1200 meters, though am not sure, for was using very loose coupling in order to cut out a number of nearby stations and ships. I would like very much to know if these were stations of your system. It is the first time I have happened to hear any of them. Here are parts of a couples messages I was able to copy through the heavy static:- No - CR - Pk = 10 Paid CR 10/16-09 (to) Miss Gladys Hudson #192 Addison Road "CN" Don't know whether this is part of same message or not "_____ every body suck ____ may for _____ love ans. sig. Sidney With only moderate static or with less interference so close at hand would have had no trouble in copying every word. Would be please to learned if such messages were sent by any of your stations and who "CR." is. Sorry we have only a 1 kW. set so could give you a call. Hoping to hear from you. I am Yours truly, F.D. Prinniger, Elict. U.S.N. U.S.N. Wireless Station, Brooklyn New York, NY Both pages are printed on United State Navy Yard, New York, N.Y. letterhead.
