Wireless mic modification
For $60 we can modify your Bartlett microphone to work with any Shure wireless system that has a TA4M input connector, or a Line 6 Relay TBP12 wireless system. You would purchase those wireless systems from a vendor of your choice.
Or, we can make you a Bartlett mic from scratch that is ready to use with those wireless systems (for $60 plus the microphone price). Just email us at firstname.lastname@example.org explaining what you want.
I recommend the Shure BLX1 analog transmitter and BLX4 analog receiver.
