Because of this, many ham transceivers have removable control panels that can be mounted on the dashboard and the main radio is installed somewhere else, such as under a seat. Midland radio is doing some interesting … Read more

Decibels are commonly used in electronic communications to describe and compare signal levels. I’ve often heard that one dB is considered to be the smallest change that a typical person can detect by ear. I recently came across this website audiocheck.net that is set up to generate different audio tones and to do a blind … Read more
