I have a tk-2180 and i love it it's easy to program and works wonders. I have the "S" button programmed as the scan, and the "A" button programmed as scan add/delete. When i stop the scan to and delete a channel from the scan list and hit scan again the channel isn't being scanned anymore which is what i want, the problem is as soon as i stop the scan again for any reason and hit scan again, those channel(s) that were taken out are being scanned again. I know this seems confusing but it can be problematic in a urgent situation when channels i don't want to hear are getting in the way of what i NEED to be hearing. Does anyone else have this problem?
