One BIG Punch custom add-on accessory for the Yaesu MH-31 microphone commonly used with many Yaesu amateur radios such as the FT-817, FT-857, and FT-897.
- AF-based speech compressor specifically configured to provide remarkable increase in talk power while maintaining good audio quality (articulation) for communication purposes.
- The unit can be mounted inside the MH-31, requires no additional electrical power, and can be turned on or off by using the MH-31's TONE switch. Note: Soldering is required
- Performance of the One BIG Punch will vary from user to user because of variations in the individual's voice power spectrum. As with any device used to increase the average output/talk power, some users will realize more or less increase than other users. Measurements using a stock FT-817 and a MH-31 containing the One BIG Punch showed that the average talk power increased by about 5 dB over the unmodified MH-31.
- With installation performed by W4RT can also be mounted alongside Heil Sound's HC-4 and/or HC-5 mic elements.
