Let me get this right. You want a station to ask if the frequency is in use.
That is understandable except he will be on RTTY and you are on another sound
card mode. Many times stations do not even have the audio running now. They
are just looking at a digital display and clicking on the
MMTTY is a good stand alone RTTY program. I don't work Olivia so can not
comment on that one.

Is a good place to look for many of the sound card modes. Many programs are
free.

Is this for a FM or SSB transmitter ? If FM then any amp should do. If you
are using a SSB transmitter and feeding it the audio for SSTV then you need an
amp that is linear. I would guess that most of your sstv transmissions are

Hello Jose,

Correct but you still have not answered my question. Indeed If I
use one tone and key it on / off I have a cw transmitter, transmitting

What do I have if I just change the tones in a random fashion?
