What's gc?
If everything on the radio is set correctly and it's not transmitting the problem is most likely the driver or final transistor. Both are easily replaced and cheap. How many mods have been done to the radio and which ones?

Probably need to replace the final output transistor.
This is typical for those who are new to radio and don't yet understand that SWR adjustments must be made to the antenna before using any radio; or else destroying the final output transistor will happen again and again!

@ ButtFuzz:Please advise me to what is a good replacement mic for my SR-497HPC... Answer: 497 is "wired like Cobra", so many choices available. That radio does not need a power mic, so purchase a stock "coffin style" mic with a decent cord, like the ones that Astatic uses. The Superstar DM-507 is my go-to. https://www.ebay.com/itm/3050474478...adANq91JSiEEnz8EGqPJRBloTgEyaVsBoCtoMQAvD_BwE $12.99 + .99 cent shipping.
