Rumanian MFA FEC system based on a 16 bit block code using a high order of interleaving structure (128 bits) which ensures excellent error detection and correction.

System is very sensitive to the Marklevel setting. If you have chosen it incorrectly it will synchronise but print garbage.

Like many diplomatic transmissions some are clear, some encrypted - therefore although you may have the right setting it will still not always print sensible text!

Two baud speeds known (164.5 and 218.3), both supported. It is also known for this system to use simple bit-masking. Recent values have been 10, 15, 24 and 31.
