This idea was talked about a few years back but faded from attention. The idea is to use fiber optic link to send the output from an indoor AMT3000 transmitter to an outdoor loading coil/ 3-meter stick.
Step one, the input to the fiber-optic transmitter will be modified to accept the estimated 60mW RF output from the AMT3000 transmitter. As we know, medium wave frequencies are relatively close to the top of the audio spectrum, so this should not be a problem. The RF would therefore be sent on the fiber, which in this kit is 14-feet.
Step two, received and converted from optical back to waveform, the signal will pass through the modified receiver/amplifier circuit, which has a volume control and can be adjusted for 100mW to the final amplifier stage of the optics receiver and coupled to the loading coil/ 3-meter stick and to ground radials.
Such a system would not violate any section of the rules for Part 15 AM medium wave because it would not constitute a “lead-in wire.” The advantage would be in keeping the AMT3000 safely indoors.
The line is open for comments.
