Yeasu M-100 and Flexradio

Hani - OD5TE

I got a Yeasu M-100 microphone and can’t seem to get it to work on my Maestro. Any advise on the settings? I am assuming it works with Flexradio..... Thanks un advance. 73 Hani / OD5TE

you need the optional power supply kit for that mic to use it with the flex  gigaparts make a note at the bottom of the m-100 add about using it with other radios

Thank you Ray. Even though they only listed some Yeasy radio and no mention of Flexradio. Will check out the kit. Tnx es 73

I just bypass the built in pre amp and it works fine with my 6400. I figure there is enough equilization in the Flex.

Thank you Craig. Are you using it through the Maestro?

When connected to Maestro, I am not able to activate the PTT and no audio goes through if MOX is pressed.

Gents, that you for your kind support. I did a lot of testing and was finally successful to make the M-100 work with the Maestro. In summary, even though Maestro has 5V on one of its pins, but once the M-100 is connected the voltage drops to 2V. There is definitely a need for external power source instead of the Maestro power source and Microphone works like a charm. I put together a cable taking its power source for a battery pack.
