[Heathkit] Problem with HW-101

[Tracy]

Hi Gene,

First two things to do. Number 1. lightly and gently clean the relay
contacts. 2. Remove the screws that secure the audio board to the chassis,
chently lift the board and clean the edges on the chassis and the board
where they come together. Heathkit was well know for chassis grounds and as
they age oxidation and corrosion win. When the relay goes front Rx to Tx or
vice versa there are some radical voltage changes thru the radio and a
loose ground will loose or make connection from the amount of current drawn
through it as well as mechanical vibration. I am pretty sure you will find
this to be the problem.
