>> 
>> I have a five-level Model 28 typing unit (LP serial 0013) that came with a short note on its background. I got it from the estate of Bill Bauer in Louisville who typed the note -
>> "This LP is the one Ray Morrison, W9GRW set up for the braille machine for Thomas Leland Lutes K4ZBC"
>> The rest of the note is about it being returned in 1981 to Bill and further travel/modifications from there.
>> 
>> I found some info on line about Morrison developing a braille tape printer, but nothing about a page printer. I don't understand how such a thing would work. I haven't tried out the typing unit yet, but at a glance it doesn't *look* any different. One thing is that the type box has the pallets arranged in numerical order rather than Baudot order. Would this mean that the machine could handle part of the Braille character set somehow?
>> 
>> I found an article by Ray Morrison in RTTY Journal about Braille TTY but it says the "monitor" typing unit is an eight-level printer.

>> Hi all,
>> 
>> After a few hours of tinkering, I was able to decode the sample WAV file on the w1hkj.com site at:
>> 
>> Page: http://www.w1hkj.com/modes/index.htm
>> File: http://www.w1hkj.com/modes/Baudot45-170.wav
>> 
>> The decoded text comes out as "NOW IS THE TIME FOR ALL" ?
>> 
>> The code uses an integer implementation of the Goertzel Algorithm originally written by Poul-Henning Kamp <phk at freebsd.org> to decode DTMF tones. It's very robust, and I've been using it for 20 years for VoIP applications.
>> 
>> The next step would be to clean the code up to allow specifying the mark and space frequencies, and then connect it up to a sound card driver. It could then be tested with a real-time audio stream from somewhere.
>> 
>> If there is any interest, I'd be happy to keep tinkering. I can also put the code up on BitBucket if anyone is interested.  
>>
