I've started writing the software to drive the DDS based transmitter for this mode, just a straightforward case of adapting my SMT Hell code, bit timing and frequency spacing can be set arbitrarily. The most difficult part of writing this will be parsing the input string of ASCII characters to generate the 'special' report codes. I may just cheat and use some unused ASCII characters but it would be nice to properly translate appropriately placed 'T / M / O' 'K' 'SK' and 'CQ' entries. There will be a delay of a few days before I can transmit anything, I'm in the midde of some low power, coherent, GPS locked signalling tests on LF at the moment. Suggest people start learning the code at the moment. Reading this at 6 words per hour without resorting to a printed lookup table could be an alternative to the Muss code test for upgrading to a class A licence !
