I have a TYT-TH9000D with the DB-9 connection modification (purchased from Repeater Builder) and a Repeater Builder USB Rim Lite for the Alinco x35 series of radios. I am my node as a simplex node. I have been able to get it to “partially work”. I am able to key it up with an HT and the Hamvoip courtesy tone come back. I have tried to set the audio levels using SimpleUSB-tune and nothing works. I have tried to enter DTMF tones will not pass. I have verified in Hamvoip that the touch tones are not passing. I tried Parrot and that does not want to pass tones.
