John,
Do not install the Power Mod unless it proves necessary. If you cannot
achieve 3 to 4 watts output on all bands with a 12 volt power supply,
you will need the change. But if you can achieve 3 to 4 watts out,
adding the mod will only stress the components in the transmit chain.
As stated in the instructions, only some KX1s require the mod. Those
that do not need it should not have the mod installed.
So build it first, and then add the mod if it is required.
