Very nice craftsmanship there, Radio Pilot.
I know of a couple of fellows who are using my mechanical installation. They are now working on suitable coils to go between the AMT3000 and the whip antenna feedthrough.
As soon as I get a chance, I’m going to rewire variable C5 to be permanently across C23. Then, using the internal coils, I’ll determine what inductance is needed for both the top of the Ex Band and to get to the bottom of it or lower, at least down to 1600. (Below that is too congested in the Houston-Galveston area.)
Then I’ll make a more efficient coil to get me to the top and put it inside the J-box between the transmitter and antenna feedthrough. For moving through the band, I’ll put small value coils in the L4 to L7 positions.
The value of C23 may need changing, too.
