I agree, Don't even start to plan to spend money until you have looked at the repeater directories and determined if there are any frequencies open. Then apply for a coordinated pair... You can then start to think about equipment while the coordination is pending, maybe getting one on the air as a test pair. Be prepared to move the frequency if you are causing problems with any other machines or receive a coordination different from one you applied for Plan to spend at least $1000 to $2000 to get a basic machine on the air.... Be careful about the selection of a duplexer for 2 meters.... There are many reject only duplexers out there at reasonable prices but they won't work for a 2 meter ham repeater where the split is only 600 Khz. If there are no 2 meter pairs available look into 220 and 440.... In some areas of the country there are still frequencies available.... Duplexers for 440 can be found for less than $100 or Ebay.... 220 duplexers will be hard to find
