Yaesu 8800/8900 extended transmit mod OK, Please don't let this turn into a discussion of whether this is right or wrong. I just want to show what is involved in modding a Yaesu FT8900 for extended transmit. I believe the procedure is the same for the FT8800. I'll check. First, remove the radio from your vehicle and get set up in a comfortable place with good lighting. You will need the following tools (no soldering iron is needed). - small phillips head screwdriver - small needle nose pliars 1. Remove the (8) screws on the cover of the radio. There will be two on each side and four on the top. Do not remove the screws holding in the speaker. In the picture you will see four large screw heads. These are for my quick release bracket (which I highly recommend). The arrows just show where the screws are located to be removed.
