Re: new radio, VR-N7500 review

Hi John,

You have seen my setup from the "external view".
My radio is inside a metal box, so I had to add the external BT antenna.
The antenna itself is just a generic 2.4GHz stubbie with male SMA connector.


I added an external SMA connector to the rig, and ran a mini coax to the point where the internal antenna connects to the BT module.

The internal antenna is just a meandering copper trace etched directly to the front panel circuit board.
The circuit board itself doubles as the front panel, there is no separate metal or plastic front face, just a plastic sticker covering the PCB.

(ballpoint pen for a size reference)

Yes, adding the external antenna connection requires cutting and soldering into the front panel PCB.

One more picture of the mess before if went into the enclosure.
