VX-7R external mike inop

[ottosykora]

I am not sure if I am right here.

Have VX-7R radio. It woks ok so far. Now I got the original external mic/loudspeaker for it. Tested, it does not work. Neiter I can hear any rx signal when connected, nor cna I transmit, even it is not possible PTT.

I thought the mic is broken and bought a brand new mic/speaker.
However it does not work either.
Thried an other VX-7R radio from my friend, both mic do not work there either.

The radios are of the black variety rather then the silver one.

Is ther some general issue known with VX-7R and external mic/speaker?

Did you get a mic with the right connector. The waterproof Yaesu's have a mic with a threaded plug to seal the mic connector. It needs several turns to seat correctly. Other mics will not insert fully into the radio and thus would not connect. Neither the speaker nor the mic would work.

Yes the mic is the correct one.
your: > It needs several turns to seat correctly. <
was the right hint

I have to screw the connector in until it goes no further. To the end of the thread.
Then mic starts work, I can hear and transmit etc.
Before, I was turning it little bit, but probably not to the final end of the thread.

External mic makes much more clear communication, however I have to set the deviation to 'half' as here the repeaters are set for maximum 2.5kHz deviation limit.

Thanks!
