Could the difference be that yours has been modified for the external antenna, and 12vman’s has not been modified?

Since the antenna is a voltage fed device, would it make any sense to increase the operating voltage of the final RF stage? To meet FCC it would need a current decrease, but as long as we stay within the 100mw input power we’re OK right?

Are there any high effeciency transistors that could be substituted for the stock units?

As you can see I’m just kind of guessing right now.

I’m going to check with my boss Monday to see if I can order one of these yet. Now is the time for “fiddling” with it.
