Les, thank you for your responses. I tried the circumvention of changing from
RTS to CTS and vice versa on my Linux system and it did not change, the
transmitter remains keyed. I will ask the station at the other end to try that
on his Windows system.
We are definitely both using the 2.4 khz bandwidth because we are not allowed
the 3.0 khz bandwidth where we are testing. We will keep looking for other
things that may help. BTW, when we could not connect with RFSM-2400 we tried
other modes (MFSK16 and MT63). Both of those modes were able to work so we did
have pretty good signals to work with.
Is there a way we could find out where and when you are using this mode so we
could try to copy? Did I read in this forum that you are using 14.109.5? Of
course we are not allowed to transmit in the ham bands but maybe we could copy
some of your signals.
Thanks again for the assist. This mode seems to offer very fast speed without
spending a lot for a modem. I hope we can make it work well.

that state until com port line is changed from DTR to RTS or vica versa
and the options
window then closed after which it will then release the PTT and work
normally until the
program is executed once again.
