the problems with similar mods to mine are that people are soldering directly to the contacts on the board (very difficult, high risk) and on top of that, combining two inputs (dangerous if not done correctly.) the only way to combine two inputs is to use a resistor to back the power down on both of them to 50%, partly to avoid gain problems but mostly to avoid damage to both of the devices. for this reason, you don't see "mixing" cables at radioshack for 2 inputs > 1 output. my RF mod doesn't have that problem and I'd be happy to do it for anyone who doesn't feel comfortable doing it themselves.
