I built my own, albeit constrained to channel 3 or 4. Basically, it's an RF modulator capacitively coupled to a 2-Meter amp. Not sure of the output, but rabbit ears produce a clean picture on the set. Ramsey kits makes a 2 meter amp - the RF modulator is an early Astec (snipped from a junk VIC-20 computer) Modulator and amp are powered by a 6V wall wart.

Aw hell, for 40 bucks, you too can build your own:
