Hi all, I need some help. Trying to set up an aprs digipeater/igate. Using an Anytone 778, digirig, cable and linux raspberry pi os. I have read and watched a ton. I believe my transmit is either too low or not transmitting. I do not see tx on radio. I do not see my beacon on aprs.fi. Most of replies in direwolf say: “Audio input level is too low. Increase so most stations are around 50.” I am assuming this message is to me, but this is my first attempt. I have tried using all 3 speaker settings: mic/main/main+mic. I do see my beacon in direwolf. I do see other aprs beacons in direwolf. Thanks for your advice.
Depending on the Digirig model you’ll need to configure PTT by RTS (mobile) or PTT by GPIO (lite). Prior to that you can test PTT hardware by simulating the signal with shorting of the pins on the connector as shown in this video:
The audio levels is a separate concern. You can use alsamixer or similar utility to configure the audio.

Thanks. Tested all as in video. Good working order. Problem must be within linux. Doesn’t appear to be an answer after reading the related discussion you sent. Some said they rebooted and it started working! What is your suggestion for radio speaker setting? I have used all and no difference. Settings are main/hand/hand&mic.
With AT-778 you are picking up the received audio from radio’s external speaker jack. Make sure the 3.5mm TRS jack of Digirig cable is plugged and radio sends audio there. From the settings it sounds like main or main&handmic should work for that.
I don’t have this transceiver but it’s customary for the radio to cut off the internal speaker’s audio when you connect the external. As you change the volume of the speaker that will also affect the audio level received by Digirig. Additional factors are the sensitivity of the input set in OS and AGC.
If you want to experiment in a more troubleshooting friendly environment, I would suggest first setting up on a regular windows PC before moving to less forgiving systems like Linux, iOS or Android.
