Okay here is what I want to do with echo link.  I want to run echo link witht the radi to the computer.  But the thing if I am running echo link on  2 meters and I want to listen to 2 meters on my other radio I have a  problem.  Also if I want to get a 440 repeater there are problems with that to.  I am so frustrated right now.  I really have my heart set on doing echo link so I can us a my hand held. I was going to take the antenna for echo link and put it about 30 feet away from the other antennas.  But I was told that would not help much.  So it sounds like I would be better off using echo link through 220 so I will not have to worry about the interference.  Also I was told if I run echo link and another frequency at the same time that I could possibly damage the radio.  Also how much would a good 440 repeater cost?  I know there is allot involved but I do not know what else to do at this point.  Also if I put echo link on 220 what frequency can I use to cross band if I need to?  I really hope that someone has some advice for me.  I know a repeater would not be a good way to go because it is expensive among other things.
