depends on what you want featurewise; performance should basically be the same.
what would make the 148 any different, or better in the receive or SSB operation? Aren't the circuit designs basically identical?
Didn't I read that the cobras, being made in China, were using really low value componenets, like 1/4 watt or 1/8 watt resistors, etc.?
Anyway, years ago I compared receivers of an old school 148 to a 959 in a side-by-side test and they both heard the same signal all the way down until it dropped off. with the 959, though, i could understand the transmission at a lower output than with the 148, but this was probably more likely due to tune, age, or mfg differences...
