So, the NIB Uniden Bearcat BCT15X arrived. While it didn't have the screen protector still on it and appeared to have a little programming for TX in it, it did come with everything that is listed on the box, most still sealed in bags and with ties on the cables, so it seems NIB enough. I went ahead and did a factory reset by following this:
I did this a couple of times and it seemed to clear everything out of it. The only thing I noticed when doing this is the part "Then, the scanner displays "Restore Preprogram List? / Yes="E"/ No="."" does not come up on the BCT15X.
I then tried a weather channel and a FM broadcast station and both were received.
Next, I took some time to wrap my head around the programming structure (Systems, Groups, Channels) and found a YouTube video that broke it down fairly well. I used a spreadsheet to outline my programming structure. Then I found a YouTube video that showed how to do the actual programming via the front panel (I like to know how to manually program my scanners). Following that video, I have 5 Systems programmed, 1 with multiple Groups, and all with multiple Channels.
Last night I looked up FreeSCAN and got it downloaded and installed on my Windows 10 PC. I have watched a couple YouTube videos on it and it looks pretty straightforward to use. I like the ability to place items on the clipboard via a Copy and import the information into the program. This will be the next thing I tackle in the next few days.
