So got a killer CB at cost brand new .  Installed the thing and I got nothing coming across it.  It turns on and when I key the mic up I can see the RF and Signal strength meter goes up to close to 5.  I don't know the first thing about CB's so I went to Lead's house and I could here him come across his CB but I could not transmit back.  This is the only time that I have heard anything.  I have driven close to 100 miles on the highway and have never heard a trucker come across channel 19.   Lead suggested that I check the grounds.  So this morning I went and Sanded the paint off where the mount for the antenna is mounted and I ran the ground for the CB and actually hooked it up properly instead of just rigging it to frame.  I gounded it on the passenger side right by the fuse box to a bolt that I think is holding the dash in place.

Welp I'm out of idea's, but don't have much knowledge in this section.  Do I just need to get this thing tuned?  Ohh the CB is a Uniden PC 68XL and the antenna I have is a firestick firefly, 3 foot I believe.
