Hi All,

Thanks for the feedback and sorry for the delayed reply. My plan is to learn Morse code and send "simulated" operational messages and contact reports. Which would also require some research into sending secret coded messages.

Starting now with this 1944 US Navy training film "Morse Code Radio Operator Training"

In addition to his many Tools and Programs for both SH1 - SHCE & SH4, Kim Rønhof made a wonderful Cipher machine emulator that we used for comms in the 'Pacific Thunder Campaign' that you might like:
Electronic Cipher Officer:

From his Readme:

1) Installment
Just install (un-zip) all the files into the same directory (The silent hunter directory is ok) and make a shortcut from your desktop to the file ECOPTC.EXE.

Example output:

PTCCOM
091141 MAR 1942 N ALL ILCOA
PART 1/1/171
EASY ITEM ABLE SUGAR ABLE
HPAYQ IVZNS EXDDD EEEDN HMVPE HJPXF DCGGN

XMMYS XVZUY YUCFO PPXCE DSFKC CKGZD JDMXX
QICOC IFSHH EYGGG RLBBU OUKDQ IEYOQ Y
END PTCCOM

- Plain text that can be Encoded and DeCiphered with the click of a button:

/CONFIDENTIAL/
CRYPTONET : ALL
DATE : 3/9/1942
IN ADDITION TO HIS MANY TOOLS AKA PROGRAMS FOR BOTH SH1 SHCE & SH4, KIM RONHOF MADE A WONDERFUL CIPHER MACHINE EMULATOR THAT YOU MIGHT LIKE.

The calendar displays a little strange in Win 7 but the dates are there.
Let me know if you want it.

Happy Hunting!

I miss the PTC.

Thanks for this info! I didn't know such a thing existed. I would like to get the Electronic Cipher Office program.

Shoot me an email address - PM and I'll send it.

_ECOPTC OV 2_0_0.zip is only 566K.

Or, if you're a member of, or can access this:
https://groups.yahoo.com/neo/groups/...cThunder/files it is there.

FYI the _EPOPTC3000.zip is something completely different, it is a plotting tool that uses the SH1 maps.

Kim's manual targeting tools are also in the files section... he is the master of manual targeting. If you try to join the group, I'll see it and will let you in. The group is inactive now but I keep it up for archive purposes.

[tmccarthy]

Will do. Thanks aanker!

Hi Tim, I uploaded _ECOPTC OV 2_0_0.zip to Subsim. Check your PM's.

A few years ago Kim gave me permission to upload a few of his programs to Subsim, I have, and it turns out that this gem is also one of them... plus it is appropriate to have here at Subsim, because US Boats used ciphered comms.

"The ECOPTC is a program that can convert a plain text message into enciphered text. And, of course, the reverse action - decipher an enciphered message. The ECOPTC uses a simulation of the CSP888/889 (the coding machine that was used on US subs in WW II)."

My email to you was returned. Gmail won't allow exe files to be sent, even in a zip. I scanned it with my AV so that isn't the problem, it is their policy.

"As a security measure to prevent potential viruses, Gmail doesn't allow you to send or receive executable files (such as files ending in .exe). Executable files can contain harmful code that might cause malicious software to download to your computer. In addition, Gmail doesn't allow you to send or receive corrupted files, files that don't work properly."

Happy Hunting! & keep up the great work on your project.

Hi aanker,

I have downloaded ECOPTC from Subsim. Looking forward to creating ciphered comms while on war patrol. Thanks again for sharing this info!
