Hi all, Been some Talk and I have got Software setup. QUESTION: at the 75 Baud is anyone Changing the Width of the Shift? I have heard 2 Sides of this, 1 to stay at 170/200Hz Shift, and another in Re

No one will be using a wider shift. It wastes bandwidth and is prone to more errors. Do you have a url regarding a "NATO standard 850 Hz Shift"? I've never heard of it. 73 de Bob - KØRC in MN _______

Hi all, sure I do! We used the LO 15 and LO 133; a bit noisy but reliable; and we used 170 Hz shift already back in 1964 with a commercial (cristall-controlled) HF-RTTY-link. Wonder why it is that no

Hi Jeff, My take so far is to just chg baud rate from 45 to 75. I saw something awhile back on this subject saying to use 7 bits bit length, but that must have been just talk. At the time I saw it I

The power problem when going from narrow shift to a wide shift is bad but not terrible. The reason is that you are keeping the baud rate, but just widening the separation of the two tones. The matche

Yes, that was a separate discussion. It was to compare ASCII RTTY (7 bits) with Baudot RTTY (5 bits) in terms of (a) the length of time it takes to send a short contest exchange that contains both nu

Yes, that is the MMTTY program that allows you to set bits, stop, and parity but it does not support an alternate character set. So you're still sending the Baudot character set no matter what encod
