Here we go again with the range finder.

Copying ITTY at the wrong speed works if you fuss with the
range finder on the receiving machine.
If the machine is set to 50 WPM, then it will work properly with
i-Telex as long as you order the 50 Baud TW39 boards.

What a range finder will NOT do. It will NOT compensate for
your transmitting speed being wrong. And unless the guy at
the other end has a ranger finder, he will print garbage.
PacComm's PK-232 and Kantronic's KAM do NOT have range
finders on the receiving side. FlDigi and Ham Radio Deluxe
do NOT have range finders on the receive side. All of them
will print garbage. Unless they are set at the correct speed.

If you try sending at the wrong speed on i-Telex it will print
garbage.
