[ICOM] PRO3 and SignaLink USB

[allan1 dejazzd.com]

I wish to operate RTTY.  I know that the PRO3 only has MACROS for XMT.  I purchased the SignaLinkUSB assuming that I could just hook it up with the supplied acc1 cable to the unit.  I am using MMTTY so I can receive on a large screen.  I can view RTTY in LSB as well as the RTTY mode.  However when I go to transmit the MMTTY Macros of just XMT I only have power on the PO meter in the RTTY
