MIC POWER :  
If the microphones, originally delivered with most CB sets,  
operate without 'internal or external' power supply,  
it is quite different with the replacement microphones, equipped with complementary circuits  
(preamp, compressor, etc.). ..).  
To no longer depend on batteries or rechargeable batteries, here is an ingenious hack.  
Compact form, this has the advantage of being both cheap and 100% reliable.  
The size of a 9-volt battery, this module is intended to power almost all microphones.  
And this, whether mobile models or table.  
By opting for this system,  
the lucky holder of the module will no longer risk being surprised by a flat battery!  
The power supply of the module can be replicated on the circuit of the CB station
