Just to get clarification, when you say "indicator goes towards negative end"....

Before you key up, are you hearing anything? Radio hash, other stations talking? And then, when you key, it just drops to the bottom?

If that sounds right, the first question I would have is... does the radio have a PA built in? If so.... see if you can find some headphones or a speaker to plug in to the PA speaker jack, switch it to PA, and key up and talk. Your speech should come out of the speaker/headphones pretty loud!

This is the first thing I would always do as it checks the path from your microphone through great parts of the audio circuitry including the audio IC if your radio has one. It just tells us a lot.

Are you on SSB or AM. There is no carrier on SSB, so you won’t see any needle movement until you modulate.

Which means Speak into the Mic.
