These small radios have been around now many a long year and have come with fans, High Power Modifications, audio changes and just about all tricks by the modifiers of radios. Mine below came from eBay Germany tricked out also. Below are the details on what was with my purchase.

Microphone is now not hard wired but it’s detachable.

External microphone lead that accepts 6 pin microphones although you need use the original microphone for up and down channel change.

External 3.5mm socket so you can run an external signal meter into the back of the radio. And now what else has changed?
