Description:

The FT-817 FT-818 is a great radio but the SSB speech power does lack "punch". This great little external AF dynamic compressor from Box 73 in Germany will aid readability and maximise the performance of your radio (essential when using QRP). Speech Compressors work by raising the average level of your audio signal, giving greater "talk power".

Plug and Play! Connects between the radio and microphone (lead included). The compressor function can be switched in or out, the module draws its power directly from the transceiver (approx. 10mA). The compression level is adjustable. Modifications to the microphone or transceiver are not required.

The speech compressors that we sell are fully built and ready to use, so the construction part of the instructions can be ignored, but there are some operating instructions near the end of the document. The potentiometers inside the compressor may need a bit of adjustment to suit you and your radio (page 10 of instructions).

The compressor is also suitable for use with the FT-900, FT-857, FT-897 and FT-450 (all versions). For more modern Yaesu radios, they may already have similar functionality built-in (look for 'speech processor' in the manual), so an external compressor might not be necessary in that case.

Note: if using an external speech compressor, any internal speech compression in the transceiver should be turned off. Otherwise there will be too much compression, resulting in distorted audio.
