Old cobra vs newer stryker

So everything is the same? Just switching out the radios? Same truck, coax antennas?

 

That seems to be the jist of it. If the cobra is hearing 10 miles away, and the Stryker is only hearing around 2 miles, then the problem is in the Stryker. It's not a bonding, coax, or antenna problem. Sounds like the technician in Atlanta didn't do a very good recieve alignment. Or at least someone didn't. A lot of techs struggle with the receive alignment vs the transmit alignment on a radio. Of course that's if the OP has all the settings set correctly on the Stryker, since he said he's new to CB radio, he may have some setting not set correctly.

 

I would agree. If the Stryker (never owned one, but I have used them when slip-seating) is sold as a 10 meter radio and had to be converted, it would need retuning. A lot of shops would just convert them and hand them back, or attempt to tune them for 11 meters and screw it up.
