It's possible that your RTL is off frequency and requires attention to the correction factor.
Questions
Are you using the charlie-foxtrot /RTL_Airband? If so, what version?
Are you using a dedicated outdoor airband antenna?
Are you using the Icecast Server option or are you using Pulseaudio to feed the audio to another streaming program?
Can you post your rtl_airband.conf file wit the BCFY mountpoint and password redacted?
I am not sure what version of RTL_Airband I am using, I just followed the guide for Broacastify.
I am using an outdoor 2m antenna, that I used previously without an issue, and I am using Icecast to stream. Below is a copy of my config.
# This is a minimalistic configuration file for RTLSDR-Airband.
# More complex configurations are possible.
# Refer to
Home
# for description of keywords and config syntax.
# Just a single RTL dongle with one FM channel
# sent to a single Broadcastify stream.
# Note that the center freq is 100 KHz offset from the receive freq
# Also, you must enter your server number, stream name, mountpoint and
# password from your Broadcastify stream "Technicals"
devices:
({
type = "rtlsdr";
index = 0;
gain = 25; # This may need adjustment depending on your hardware
centerfreq = 151.025;
correction = 0; # this can be determined using "cumulative" output from running 'r$
channels:
(
{
freq = 151.025;
modulation = "nfm";
highpass = 320;
outputs:

port = 80;
mountpoint = "########"; # Note: Do not include a leading slash "/"
name = "#######"; # Change the name to your monitoring $
genre = "Public Safety"; #Change the name of genre, might be Public Safety
username = "source"; #Keep this as source for Broadcastify
password = "######"; #use password on technicals page
}
);
}
);
});
