I am using an Icom IC-7100 with a reflector three miles away. I have connected the Icom to a Mobilink TNC-4 device. Radio mail can send messages via telnet (internet) but not through packet using the Mobilink device. I've tried every setting I can think of, turned squelch off, adjusted the volume, etc. . I have no issue with connecting with repeaters pretty far away. Radiomail does not appear to work with this device and this radio. Any suggestions?
Thanks for the details. The IC-7100 and Mobilinkd TNC4 should work with RadioMail, so let’s walk through basic steps to troubleshoot.
1. When you try to connect in RadioMail, does the radio key up (PTT)? If not, the TNC may not be triggering the radio. Check your audio cable and settings.
2. Use another radio to listen on the same frequency. Do you hear packet tones when you try to send a message? If not, the TNC may not be sending audio properly.
Listening to the frequency with a separate radio, I do not hear the packet tones when I send a message. The store that sells the Mobilink TNC 4 does not respond to emails, but perhaps the device is defective.

Does the radio keyup? There is also some settings in the mobilinkd configuration app on how to trigger PTT. That might need an adjustment for your radio.
