- What radios do you own?: GP300,HT1000, GM300, MT1000,
MSR 2000 or any Repeater?
What kind of wattage does a MSR 2000 put out, or other than that. whats a good solid (Older Crystal) Repeater to look for like on ebay?
The Motorola MSR2000 and MSF5000 are both good units. Usually 100 watts, but not always. GE (Ericsson) Rangr, Delta and Orion models are more scarce, but are good quality fixed stations. The Kenwood TKR 720 (VHF) and 820 (UHF) are excellent desktop 50 watt repeaters. Motorola makes some decent desktop repeaters. Look for the GR300 and 500 series. Older high power (rack mount) repeaters include the Motorola Micor and GE Mastr II units.
What frequency band are you wanting?
Is repeater operation necessary?
What is your coverage area?
What funds are available?
How knowledgable are you about radio and repeater operation, and the construction of this type of a radio system?
There are a lot of variables here ...

My two bits worth:
Who is going to re crystal, and maintain your repeater?
Not all technicians will work on all equipment.
Many of us are factory trained, prefer to work on certain models.
Your technician will require the following in addition to the usual test equipment, model specific items such as:
Tech manuals, jumper cables, extender cards, special tuning tools, test set
required for tuning and maintenance. Source of replacement components.
Experience helps too when dealing with commercial grade stations. You would not want to pay the time for a technician to learn your station, as well as acquire all the specialized test equipment such as dedicated test set. Nor would you want some one to "Wing it".
See what your technician recommends for your particular requirement.
Duplexers, other filters, as well as antenna systems have to be considered.
The next issue:
A lot can happen to a repeater in 20-25 years.
Was it in a tar paper shack getting soaked every storm, with vermin and wasp nests? Hit by lightning every storm?
Sitting in a damp garage for the last 10 years or so?
Operating in a nice dry closet at 135 deg for 20 years?
In a roof top water heater room in Wakiki hotel with 1/4"salt rust and heater soot?
Or was it in a commercial air conditioned site?
The condition of the Electrolytic capacitors, as well as the board contacts are a concern after so many years.
What condition is the PA in?
Were past repairs properly done?
If you intend to install the repeater your self, and send it some where for repairs, size and weight might be important to you.
The Micor, MSF5000 (My favorite), GE Mll all weigh about 160 lbs.
It is possible to remove heavy modules, such as PA and Power Supply
for transport.

No trees were harmed in the posting of this message...however an extraordinarily large number of electrons were horribly inconvenienced.

Only about 40 years in 2 way.
24 with Motorola.
In my job as "Motorola Area KW Customer Service Engineer" I did trouble shooting, and installations in Micronesia, Guam, Philippines, China, as well as the Hawaiian islands.
I have repaired many radio systems that never worked properly because whom ever installed and maintained the equipment had no idea what they were doing.
Consider all the experience available for the asking on the board!
Some members were my mentors from the Motorola factory.
Chances are that you can get your questions answered here, or at least ideas to solve your problem.
