Aren't the 15 & 246 essentially the same radio ? If your 246 is programmed to your satisfaction and is working well for the stuff you are monitoring, why not program the 15 the exact same way. In your post you said " Any tips on programming it properly?" Honestly, I don't think there is a 'proper' way to program a scanner. There are as many ways to program a scanner as there are scanner users out there. I think my radio is programmed 'properly' for my listening pleasure. Using Toronto Public Safety as an example, if we compared our 246s they will be totally different ! I'm looking to get another scanner (digital), if I do, it will be programmed the exact same way as my 246, plus all the digital goodies out there !!!
