[MRCA] Teletype paper

[Ray Fantini]

That's what happens now, I can get one leg of the "X" or the other but not both together. Just have to convince others to try old school 850 Hz, have MITTY on a computer and can do TTY that way just after having to work on computers all day at work have no desire to play with them on my time off. Not unless they are at least thirty to forty years old first. The goal is to get al this stuff up and working in its original configuration.
Also did try to join into "Greenkeys" again and once again the same results- not a word back. 
What's the status of TTY opps in the Bat Cave? What about you're GRC-19? Got the modem for that? There will have to be a special prize if not just bragging rights for the oldest operational system when we do the net.
Anyone can do a rice box with a laptop so they would score something like a 0.5, modern radio with Ham TTY codec and teleprinter would be 1.0, and any military radio with teleprinter will be 10.0 with a multiplier of 2 for every decade of service. Weighing the scoring table like that a GRC-19 with mechanical teleprinter would score 50 or 60 points!

   And yet another brain fart, take a signal generator and pick a center frequency and slowly sweep up and down to check the limits of the "X" 
display.
