I will be honest with you cause that is something I firmly believe in, yes its a challenge and I like it maybe because my work background has been in computers hardware , networking and software with some programming so I look at this marvel as a computer. I started with a BearCat scanner back in 1968 that required adding crystals to it for each frequency then some years later I purchased a analog BearCat but my area went Phase II shortly after my purchase. Yes it would have been easier to have went in steps up to this model but I will be 70 this year and I have come to realize that time is short so I skipped the steps. Thank you on the reply its appreciated.
