One BIG Punch
PEASE READ THE FOLLOWING CAREFULLY
 BEFORE PURCHASING THIS PRODUCT.

Installation of the OBP into the MH-31 requires reasonable skill with a soldering iron and simple tools typically found in most amateur radio operators' ham shack. W4RT Electronics DOES NOT Provide ANY Technical Support to Those that Install the One BIG Punch Themselves. If you don't feel that you have the necessary skills to install the OBP after reading the One BIG Punch Installation Manual, then please consider having W4RT Electronics install the OBP for you for an additional fee. Otherwise, you should not purchase this product. As with any audio device, it is possible that you may experience interference (feedback) when the unit is placed in a strong RF environment. The RFI suppression methods used by W4RT Electronics should mitigate such issues in virtually all cases. Such interference cases with the W4RT OBP is very, very rare.
