Directions below:



This speaker is originally designed for train models, and has exactly the same dimensions than the original.

Speaker data:
Outside diameter: 57mm.
Total height: 12mm
Characteristic: 8 ohm, 2 watts.
Manufacturer: Massoth ref. 8241020

We identified two main differences when compared to the original: the cone material is Mylar instead of the paper used for the original. Mylar is a plastic with good audio quality. The power was increased as well, as the stock speaker is rated at 1,5 watt.

Here you can see both together:

We bought the speaker on Internet. Once it arrived opened the FT-817, unscrewing 7 screws.

You have to open carefully the top part, because the speaker cable is not long. Then you can free the connector and release the cover.

In orther to remove the speaker from the cover you have to unscrew another two screws next to the speaker holes.

Next operation was to remove the original cable with the connector using a solder and replacing that in the new speaker.

The last operation was to remove two foam gaskets from the yaesu speaker (from front and back sides) and put them in the new one. One helps to seal the speaker against the cover and the other to protect the back side against the bracket.

All done, connect the speaker, screw all back and finished.

The sound was perfect, good audio response, and much louder and clearer than with the failing speaker.
