TwinTalker 3600 Mods

Finally I modified my little TwinTalker 3600. I had to do it because my first PMR446, the used TwinTalker 3500, suffered deafness and its output was less than 200 milliwatt.

In place of the original antenna (the spring), I welded a SMA connector and a BNC adaptor.

I used a SMA connector because this radio has very microscopic dimensions. Plus, because the TwinTalker 3600 was opened, I lightly increased the modulation of this radio that was a little bit weak.

Below the TwinTalker 3600 with SMA only and with SMA-BNC ready to link to an external antenna.

Here is my little TwinTalker 3600 opened on the surgery table and ready to be hacked with a SMA connector.

Finally the soldering photos. Remember always to solder the connector's ground, in the nearest point where we withdraw the antenna's signal.
