Here is a link to the TA280 manual, which is similar to the TA200, http://www.giantintl.com/RadioPDFs/Outdated%20Manuals/T280_User_Manual.pdf
Funny thing, I haven't found the TA200 manual in English. Here it is in Czech: http://www.cbradio.cz/doc/Motorola/PMR%20TA200/manual.pdf If you do a google search, you can find the page and have it translated. I'll keep looking, and if I find it in English, I'll repost.
Here is the manual for the T5720. It may be very similar to the model you have.
If it does- yes, it will pick up other 2 way radios.
