Description:
One BIG Punch (OBP) is a custom add-on accessory for the Yaesu MH-31 microphone commonly used with many Yaesu amateur radios such as the FT-817. The One BIG Punch is an 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. The One BIG Punch can also be install inside the FT- 817 and then no modification to the MH-31 is required.

One Good Accessorie! Time Owned: 0 to 3 months.
I have severla small speech compressors for the 817. After lots of testing the OBP is a sure winner. On air reports have been very good. I did find the stock mic element had too much bass for DX work. I installed a Heil HC4 and HC5 element. The HC4 uses the OBP for killer SSB and the HC5 is direct for FM work. I used the switch on stock mic to switch between the elements. Also having a venting port helps also. I just leave the rubber cover off the up down switches.
