R-392 Headset (p392 наушники)

This is the headset of the R-392 man pack radio. It uses a dynamic microphone, as well as a dynamic speaker. This is a typical setup for army radios, since dynamic microphones are more resistant then capacitor or piezo based ones.
However most amateur radios only work with those. So I had put in a piezo microphone, in order to get this thing running with my Wouxun KG-UV6D. The speaker is good to go without any modification.

The design is rather unique – the microphone rests on the cheekbone. This way the ambient noise is massively reduced. It’s the same working principle throat microphones use. This is obviously a good thing to have for a headset, which should work in combat situations with a lot of noise around.

The R-392 radio, which this headset belongs to, was developed in the 1980’s and can be still found in service. It offers 6 fixed frequencies: 44.3, 44.6,44.9, 45.2, 45.8 MHz. The design of the device itself is pretty similar to its predecessor – the R 126.
The radio is carried on the back and often used in the role of a patrol radio.

  1. Hello,

    I have read your review and I’m very interested by your modification about the microphone.

    Also, I have doing researches on the web about it, however, I only found piezo contact transducter or buzzer.

    Could give me more informations about the type of piezo microphone you have use for the headset modification?

    Best regards.
