Are you converting from baudot to ascii? Otherwise it will look like garbage on the PC

Subject: [GreenKeys] RTTYART Capture Program

Hello group, I have been trying to make the RTTYART capture program to work with my TTY setup. I have sampled off my demodulator output a TTL
signal which is fed onto the UART circuit that feeds the model 28 normally and works.. This TTL signal I fed into a MAX232 chip to convert back to a RS232
signal and is connected to my serial port on the computer.. I installed the program and set it up as best as I can figure after reading the documents but
all I get is garbage on the display.. Groups of letters sometimes and so on.. I am monitoring the ITTY signal as the source and my question is this:
Should I be seeing what the ITTY signal is being printed on my 28 machine??  The point where I am sampling the TTY signal is the normal 60 WPM signal
before it goes to the UART and is converted up to 100 WPM for my 28 that is geared for 100 WPM...
Any suggestions will be appreciated.. Skip
