HAM RADIO REPEATER INFORMATION: RADIO,REPEATERS,DUPLEXER,CONTROLLER, CONVERSION, MODIFICATION

Looking for information on ham radio repeaters. Anything pertaining to repeaters. Conversions, , mods, tuning. Duplexer, feedline, antennas.
Email me and I will look at the info and post it on website with recognition to the senders.

Looking for input on Service Monitor operation: There's alot of hams without professional knowledge on there operation.

Need detailed information on building a repeater for 1st time repeater builders. (Best repeater, radios, duplexer. antenna and so on.)

Echolink, IRLP, Digipeaters, Interfaces: setup and configuration on radios and computers.

Best place to buy, or find this stuff.

Especially looking for articles in LAYMEN terms. Things the average ham will understand.
There's a lot of articles on conversions and tuning that don't explain the process very well. Like using 2
radios to make a repeater, radio setup, controller setup, ect.

I'm not trying to repeat everything that's already on other websites, but trying to simplify some of the things that maybe confusing.
