With age, I am wondering if I am right or wrong on it being R-Y.
Was it R-(?) ??

You are correct in the RY. Those two letters are the reverse of each other
and should move the mechanical selectors from one extreme to the other . It
is possible to have the receiver set to the wrong sideband or the
demodulator reverse switch set to the wrong position and you will receive YR
instead of RY. This makes for interesting problems for the new to rtty
person. If a transmission starts off with a line or two of RYs and you are
receiving YRs, when the main body starts up you will receive jumbled
characters.


Altho , this is with the old 5 level code. For ASCII, there is no such
test, tho the closest you can get is the " J * " characters (J, then
upper case 8) as explained by an old boss and teletype mechanic.
and to compound it, the ASCII characters can use 1, or 2 stop bits at
the end of the characters! As info, Jim NN7K
