I'm attempting to build a powerful, analog TV transmitter that fits inside a briefcase. At least 5 or 10W, hopefully more?
Most builds I've seen use a consumer grade RF modulator, which limits the TX range to channel 3/4. For other channels you need an agile modulator which is huge and probably overkill for constant TX on one channel. Also, I want MTS, but my Olson agile modulator doesn't support it.

So, how hard would it be to modify one of those mini-modulators for channel 2 operation? I'd imagine it would involve swapping a crystal at least.

And, changing the RF output impedance from 75 ohms to 50 ohms?
