TAIT Electret Microphone Modification
The club has obtained a quantity of Tait 2020 transceivers for the use of club members. These are programmed for the 70 cm band and are suitable for use with the VK4BA repeater.Some of the standard dynamic microphones have lost output with age. This project replaces the dynamic element with an electret insert to restore modulation.
