Allow me to modify my question for clarity -
What information suggests that the coil was removed along with the trailing wire?
The coil would not have occurred to me as needing to be removed - why would it not just be left in place?
Jeff,
I guess you’re really asking why I wrote “. . .I’d
think that it [the loading coil] went when the trailing wire antenna did.”
Be aware that I’m answering in accordance with an assumption I expressed in an
earlier post; namely, that the 500 kHz modification included elements that later appeared in the production 13CB transmitter. I have no documentation to prove the assumption.
The subject loading coil was external to the transmitter. It worked in conjunction with the trailing wire antenna and components internal to the transmitter when operating at 500 kHz. With the trailing wire antenna removed, the loading coil served no purpose. With no purpose, it was dead weight. Dead weight was anathema to AE.
