What free programming software for Windows can I use to program my BCT15X?
No, they require different cables. You can use a USB-1 or similar cable for the front panel serial port or a DB9 type on the rear panel. Amazon.com should work, there are other third-party ones as well. You can also use the serial cable that came with the scanner with a USB to Serial adapter.I have a BCT15X and a PRO107. Can I use the pro 107 cable on my BCT15X to program it in windows?
FreeScan works with the BCT15X, while no longer supported it should still be able to be found.I have a BCT15X and a PRO107. Can I use the pro 107 cable on my BCT15X to program it in windows?

They did, called UASD but I think it died out years ago.Did Uniden make software for programming the BCT15X?
Agreed, ProScan is the best investment I've made to supplement my scannersProScan works great for me on BCD996P2 and BCT15X! I don't change the programming often and have to remind myself how ProScan works but it has been a good $50 investment. If you are thinking of programming once and leaving it that way, there is a 30 day free trial with Proscan. But I bet after you use it a few times you will go ahead and buy it...BTW that's $50 just once...no charge for upgrades.
ProScan and ARC-XT both work great but cost $50 and $40 respectively.
Definitely recommend Proscan over Freescan as the latter has become abandonware at this point (no updates in over 10 years)Agreed, ProScan is the best investment I've made to supplement my scanners

If you let us know where in the USA you're located we can direct you to the proper RR database page & point out any potential pitfalls which may hinder your scanning experience (encryption, simulcast distortion, others). Also your BCT15X will only handle analog frequencies so you'll need to be certain your area's ops are still analog. Otherwise you'll need to upgrade to a digital scannerware can I get free frequencies?
