Cobra’s 142GTL was a successor to the Cobra 139XLR. Styling was nearly identical but the electronics were much more sophisticated. Dynascan’s 142 used an advanced PLL which allowed it to be more ‘capable’ of frequency modifications. I used a Cobra 142GTL as my main base station from 1982 until 1984. It was great radio with a very sensitive receiver, strong transmitter, and very clean audio.
