I can't seem to find this in any of the manuals. This is where the SQL mode goes and normally on this repeater it shows ENC which allows me to send the PL tone and access the repeater. But when I turn on the APRS modem and come back to this channel it shows this and I can't access the repeater anymore. I'm sure it's just a setting I need to change or learn more about how the APRS modem on this radio works but I literally can't find this symbol or what it means anywhere in either manual. If I change the radio mode from Auto to FM it shows SQL, I think because I have a voice squelch on the APRS modem setup page so I don't here the packets. Thanks. Also if anyone wants to help me make more sense of how the APRS modem on these work better I would love to chat.
