![]() ![]() Holding the mic at a sensible distance from Your mouth is also important and with sensitive microphones do not hold the mic directly in front of Your mouth as this produces ‘popping’ and ‘wind noise’ as You speak. ![]() Just like any other radio equipment if You over drive the mic input the transmitted audio will suffer from ‘clipping’ become ‘crackly’ and hard to understand by other stations receiving Your transmissions. Try to set the ‘recording amplifier’ so that the ‘LED bar graph’ does not go above 3/4 of ‘full scale deflection’ and is always below the red. This will record Your test transmission and play it back to You enabling You to make fine adjustments and get clean audio at a sensible level without disrupting channels or calling on channels for an ‘audio test’ or ‘mic check’.Īfter each adjustment, go back out of the options and return to the ‘Talk’ screen (with the on screen PTT button) and make sure that when You transmit the ‘LED bar graph’ at the bottom of Your talk screen (below the on screen PTT button) does not go into the red at voice peaks. When setting up Your microphone and bluetooth headset or external mic audio levels it is best to go to Your ‘Contacts’ list and select the contact called ‘Echo’. I always ‘un-check’ the ‘Automatic’ boxes and use the manual sliders to set the levels on each device. The ‘Recording Amplifier’ adjusts Your transmit audio level (Mic Gain). In the Audio setup menu You will find two sliders, the ‘Playback Amplifier’ adjusts the received audio level. Zello ‘three dots menu’ / Options / Audio. You may notice some operators using a -1 or -a suffix on their ZelloID / callsign when they are operating from their second device on their secondary account. If You wish to have Both devices logged into Zello at the same time You will have to create a second account for the second device then add the channels and contacts you wish to use on that specific account. if You are logged in on device #1 and You login on a second device, You will get automatically logged out of device #1. With One Zello account all the channels, contacts etc added to an individual account will be accessible on whatever device You log into that account from but You can only be logged in on one device at a time. If You have more than one device You may find it handy to create a Zello account for each individual device. Unlicensed radio enthusiasts can create a new Zello account using Your Name + Location It makes sense to use a short account name like Your official licensed amateur radio callsign + name. The account name You choose is ‘locked in’ and can not be changed later. When You create a new account on Zello take a minute to think about Your user ID/account name. Creating a Zello account User ID / user Name… ![]() You may prefer using a newer version but I personally prefer V4.05 for speed, efficiency, and stability. V4.05 is also the last version to display the ‘Add’ function at the top of the display (as seen on screenshots below) instead of using the annoying Blue + circle that obscures the Recents, Contacts and Channels lists etc. V4.05 also displays profile and channel images correctly, newer versions display them ‘cropped’ into a small circle making many impossible to read properly. I have tried newer versions of Zello but always revert back to V4.05 as it reacts much faster and has lower latency than newer versions. This is used for adding channels, contacts and PTT buttons (depending on which screen/tab You are in) I personally do not use Zello versions with the Blue + circle as it gets in the way and limits workable screen space on devices with small screens. Newer versions of the Android Zello app have a blue ‘overlay’ circle at the lower right of the screen with a ‘ + ‘ symbol on it. Other versions of Zello running on older versions of Android will look slightly different and may not have all of the features available on the latest version of Zello PTT app but the process of adding channels and operation are very similar. The information and descriptions presented on this page were compiled using Versions 4.03 and 4.05 of Zello with screenshot images captured from an Inrico T320 handheld network radio running Android 7.0 OS and Inrico TM-7 network radio running Android 6.0. ![]()
