Hi all I am new to this site, so please be gentle till I get my feet wet.

I have a Cobra 25 WX-ST, I am checking it on the bench and I get the weather channels but when I go to the cb all I get is a deep HUMMM. Any ideas as to what might be wrong?

Thanx in advance,
Malo

I am using a 13.8v power inverter. Do you think it might be bad? I will try another one tomorrow and let you know.

Thanx
