Ok so I have an old mts200 that I have been using for a specific use for about well lets say six years. I was unaware that they came in different freq ranges. So I bought two more thinking I could program them to match and have three working radios for my purpose. So I then got the cps and a ribless cable. I connected the first (my original) radio and read it. I looked through all the stuff in the cps as I am new and didn't know really what I was looking at. I am tech/computer savy for the most part and am really good with hardware. So I figured I could do this and figure it out. So I saved a copy of the info to my desktop from the radio. I then disconnected it and hooked up the second one (mts2000 model III) and read it. I see that the freq are different. My original (mts2000 model I) is showing 460 MHz freq and the second is showing 850 MHz freq. So I saved a copy of the info to my desk top. I then hooked up the third radio (mts2000 model I) it also is in the 800mhz range. So I have found out through research online that I cant change the freq range on the second and third radios. I think I will sell them off so I can buy more 450-512 MHz range radios. Most likely two or so mts2000's and maybe one or two mcs2000's. Then I had a though. I found on here a list of freq used locally for police, fire, ems, and local companies. So if I program both 800 MHz radios for freq's not used by any local agency or company can I use them for my son and I to have some fun with? If not ill sell them but I was wondering if I could before I do sell them. Also I am wondering how I remove the trunking from the two 800 MHz radio in the cps. That way I can program them conventional with freq's that are not used locally as I said. Is there anything else I should know I am very new to all this. I just had the original radio and it wirks so well for what I use it for that I wanted a couple more. I knew nothing of radio and programing before I started trying to figure this out.
