600ohm vs 50k ohm mic

Hello everyone,

I have a Yaesu td 148 microphone with a selector switch in the back for either 600 ohm or 50k ohm which do I set it to?

 

Typically, for tube (aka vintage) radios, high impedance (50k ohm) and for modern radios, low impedance (600 ohm.) Read the manual for the transmitter/transceiver for the best guidance.

 

Thanks for the reply I took your advice...I Found it in the manual....stop and read the manual Dave... haha thanks

 

You can always try both settings. The one that does not cause smoke is the right one.

I found that a hi Z mike is partially shorted out by the low Z mic inputs but a low Z mic may work fine on a hi Z input.
Still good advice from a "strictly CW " operator

 

Never cut the red wire.

 

My supervisor insisted it was the GREEN wire that shouldn't be cut. Then again, he was color blind...
