FCC has opened up two new HAM bands. An NDB transmitter can be modified to operate on those bands. An ADF can be used as a receiver. I have the ADF. I need a de-commissioned NDB transmitter. My home drome has already disposed of theirs. If anyone knows of an NDB that will be taken out of service, or has been taken out of service, and the equipment is still kicking around. please let me know.
