The best replacement for a part long-since discontinued depends in part on the circuit where it's found.
The 1306 was used as the driver transistor in sideband CB radios. And in AM-only models, it was used as the final stage. Hasn't been made for decades.
The 2SC2166 is what the radio factories switched over to when the 1306 was no longer made. This is the best choice as a sideband driver transistor.
An AM-only CB may also use the 2SC2078. Those are still showing up in new AM-only radios made recently.
And there are other substitute numbers that are valid, but all of those are also discontinued.

2SC2166 is what Uniden's assembly line used after the 1306 was discontinued. If your radio was built with a 1306, it must date back to 1981 or earlier, pretty sure.

I got some from Barket electronics a while back for my Madison.
Oh, yeah that's Golden Eagle. My bad.
