![]() In quiet locations the suppression function can cause distortion on Your transmitted audio. This feature should only be use when necessary. The Noise Suppression function can be used to help reduce background noise when using Zello in noisy locations. Zello 'three dots menu' / O ptions / Audio. If You see channels listed named 'Echo' or 'Echo Test' they are NOT the proper official Zello Echo test facility and should Not be used. The Echo test facility is a 'contact' Not a 'channel'. Note: The ECHO in Your contacts list is the only proper echo test facility on Zello. Using the channels with audio levels that are very low or very high makes it much harder for other operators to hear You properly and it is bad practice to operate with poor audio especially on Zello as the system provides excellent quality audio when the levels are set correctly. 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. Many licensed amateur radio operators use an account with their HAM radio callsign on one device and second account with their NR callsign on another device. You may notice some operators using a -1 or -a suffix on their 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 with the same account, 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. The moderator can check availability of specific NR callsign numbers and arrange registration of an available NR callsign for You. To register an NRcallsign You need to call a moderator on one of the channels, - or - contact a moderator on the Network Radios facebook group. You need to register an NR number Before attempting to use it on the channels. NOTE: Do Not set up an account with an NR number that has not been registered with a channel moderator!Īny account attempting to use an unregistered NR number will NOT be 'trusted in' and may be blocked from the channels. Licensed Radio Amateurs can use their official licensed amateur radio callsign on the channels and use their registered NRnumber as a 'club member number'Īnyone who wishes to register for a NRcallsign / NRnumber should contact a moderator on one of the Network Radios channels. Unlicensed radio enthusiasts can use their registered NR callsign on the Network Radios channels. If You have a registered November Romeo 'Network Radios' callsign You can create a Zello account with Your registered 'NR number' Unlicensed radio enthusiasts can create a new Zello account using Your Name + Location or Your registered NR callsign. 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. ![]()
