    I would like to participate to the RR (my first RTTY contest) this afternoon. I successfully setup N1MM to RX/decode RTTY message with MMTTY and 2Tone on my Icom IC7300. However, my TX seems to have a problem. When looking at my transmission from a remote KiwiSDR, I see that I'm transmitting (which confirm some control of the radio) but instead to see/ear modulated data, it look like more like a single tone.

    N1MM's DI-1 MMTTY Mode is set to FSK, IC7300 is in RTTY mode with USB SEND = DTR and USB Keying (RTTY) = RTS.

    Anyone have I idea what I'm missing here?

    Thanks to help me with that, hopefully I see soon on the air!

    I think MMTTY uses the TXD pin by default, which the IC-7300 doesn't support.

    The manual says you need to install EXTFSK (in the same folder as MMTTY) to permit defining RTS for FSK keying.
