Reverse Morse Code (RMC) Conversion Tool
(An online utility for reversing Morse code elements)

Purpose:

See how a word, phrase, or callsign would appear if the corresponding Morse code elements were sent backwards, in reverse order.

Features:

· At least 57 different characters (34 reversible and 23 symmetrical) are recognized and converted in either direction, including the entire English alphabet and all numbers.
· Up to 80 characters can be typed or cut and pasted into the converter at one time.
· Certain Latin characters (with the grave or diaeresis accents) are permitted for backwards compatibility. However, the accent on these characters can be ignored.
· A checkbox optionally allows the resulting text to be displayed with only the character elements reversed, not the entire word, phrase, or sentence.

Instructions:

Enter any text in the box to be converted, and press Convert. Reset clears all text.

NOTE: An asterisk (*) indicates an invalid Morse code character.

Examples:

The two English words "tan fins" written backwards spell "snif nat", but in reverse Morse code, they spell "sail ant".

Similarly, the two English words "net tow" written backwards spell "wot ten", but in reverse Morse code, they spell "got tea".

More Examples:

The word "wig" is a palindrome (a symmetrical word) in Morse code, because it also spells "wig" in the opposite direction. In the RMC conversion tool, try this other palindrome: "fool". Try these words with the 'Reverse characters only' box checked: "hostess", "immerse", "poems", "smirk", "thesis". You can also try the palindrome name: "Bev".

The word "tidy" is a semordnilap (containing two different bidirectional words) in Morse code, because it spells "quit" in reverse Morse code. In the RMC conversion tool, try the semordnilap name: "Robert"="Trevor". Try these names with the 'Reverse characters only' box checked: "Mike", "Rose", "Skipper", "Spot", "Tom". Also, try these words with the 'Reverse characters only' box checked: "fiber"="liver", "get"="wet", "life"="file", "tense"="tease", "vent"="beat". You can also try these other semordnilaps: "own"="ago", "peg"="wep", "sewn"="ages", "spot"="tops", "tool"="foot".

History:

A palindrome (http://en.wikipedia.org/wiki/Palindrome) is a symmetrical word or other sequence of units that can be read the same way in either direction. An example of a palindrome is the English word "radar". Palindromes have been around since 79 AD or earlier.

A semordnilap (http://en.wikipedia.org/wiki/Palindrome#Semordnilap) is a type of anagram that has the reverse spelling of a word and itself spells a word. An example of a semordnilap is the English word "regal", which spells "lager" when the letters are in reverse order. The word "semordnilap" has the reverse spelling of "palindromes", and is itself a semordnilap. Semordnilaps are also known as heteropalindromes, anadromes, volvograms, and several other names. Again, these are simply words which are also words when spelled backwards.

The RMC conversion tool is a simple online utility that lets a person translate an English word or phrase as a series of International Morse Code elements in reverse order (backwards) in order to discover fun and interesting semordnilaps (heteropalindromes, anadromes, or volvograms) that can be sent using Morse code. The RMC sending and receiving technique can be used as a simple encryption method to communicate with Morse code in a fun and exciting new way.

For example, if your name is "Bob", you can send "Vov" at the end of your messages to your friends. Use the new cryptic sign just for kicks. It's great for unusual tag lines on messages too!
