Grounding antenna on Mack granite

Let's start with the radio, is the squelch off and rf gain up?

 

I'm with Ridgeline here. Squelch all the way to the left and RF gain all the way to the right. The Granite mirrors are usually grounded well enough. I believe from 2010 and newer they ran a ground cable from the body to the door in the door jam.

 

What's calibrated correctly?

 

After you calibrate it and flip the switch back to swr, what’s the swr reading according to the radios meter? Have you used this radio before? The words cheap antenna raises a red flag for me.

 

OK stop transmitting with the radio.

I have to suggest that you take it to a shop and have them look at it.

Something isn't right, maybe it is a mic issue or the radio is toast.

 

I dont lime jow he ran the coax through the door either..Would still get noise but still....

Silly thought but what if its in pa mode?
Dont think you could do a cal set up then anyways or could you,dont remember..
