Can I power the TM-1 from the radios mic connector?
Yes, if adequate voltage and current is available. The TM-1 requires 8 to 15 VDC at about 45 milliamps for operation. If your radio can supply this power, then you can power the TM-1 from it. You will need to check your radio’s manual to verify power availability. WARNING: Overloading the mic connector power supply will damage your radio!
