[GreenKeys] question about TTY signals and Telephone Signals

[Eugene Hertz]

Well, I guess I'll try it first seeing thats the path of least resistance. If the results are bad, I'll probably have to take up your suggestion. I guess the other option would be to send audio down from the shack to my office, then get an ST-6 to do the rest. 

Thanks again to all
Eugene
