Jeff,
I have a working ESP1000 repeater, and I am convinced that it is not worth
the effort and expense it will take to convert it the 220 Amateur band.
The primary impediment to conversion is that the SEA ESP1000, and all of
the mobile and portable radios associated with it, operate on companded AM
single sideband. I talked with an engineer at the company that now markets
SEA products, and he told me that the conversion to wider bandwidth FM
would involve a major redesign of both transmitter and receiver. In
addition, the synthesizers are blocked from being programmed out of band.
Perhaps the most practical action is to throw away the SEA transmitter and
receiver boards, and replace them with Hamtronics or Maggiore modules. At
least, you'd be able to use the chassis and power supply.
