FTM-400 Digirig issue

Mark C All Messages By This Member #2197 开云体育 Hi Tim,? The Digirig relies upon RTS to PTT the radio (I cannot remember if its -RTS) how are you setting up the PTT? Also, I've found that RFI getting into the USB line can lock up some devices though I've not seen this with digirig.? I need to play around, but I've also found that since Digirig isn't a TNC, the easiest configuration for me has been to use direwolf as the "TNC" and configure it to PTT the digirig. Then point YAAC at Direwolf via the KISS/AGW network port. --Mark K6EF toggle quoted message Show quoted text On Dec 19, 2023, at 12:48?PM, Tim Huffaker <thuffaker@...> wrote: I am trying to use a Digirig with my FTM-400 and when I select the digirig audio port with YAAC the radio PTTs. ?This happens when I test the port and will not stop unless I shut the port down. ?It would be nice to make this work because I can use it for APRS and RF email that works. I do not know where to look to fix the problem with my FTM-400 PTTing when you select the port. ? My system is a Mac M1 Mini with YAAC running and I am using a Serial TNC port I tried a Yaesu port as well. ?Both ports caused the FTM-400 PTT when the port was selected. ? ?Let me know what I can do to fix this issue.

All of those YAAC port drivers you specified in your emails are meant to use a serial port to talk to a hardware TNC, such as a TNC-2 or what is built into the Kenwood TM-D710 control head. The Digirig is not a hardware TNC; it is a sound card and PTT controller meant to be used with a software TNC, such as AGWPE, UZ7HO Soundmodem, or DireWolf, and the software TNC (not YAAC) controls the PTT. The reason the radio jammed into transmit mode when you selected the Digirig's serial port is that serial port communications use the modem control signals on an RS232 port to indicate when the cables are hooked up and the data terminal and data modem are ready to communicate. So, when YAAC opens a serial port to talk to a hardware TNC, it turns on the RTS (Request To Send) modem control signal, because it's ready to send and receive packets (not necessarily actively sending them right that instant). However, the Digirig uses the RTS signal to directly control the PTT and ignores the TxD (Transmit Data) and RxD (Receive Data) signals entirely. If you want to use a Digirig for APRS, you will need to use one of those software TNC programs to control it. There is no software TNC built into YAAC. Hope this helps.?

The FTM- 400 Also PTTs when you test the port. ?I am only using the Adudio of the digirig and this is strange that it PTTs. ? _._,_._,
