I've read post on here and through the manual many times, but I am having trouble understanding how to program the trunked stuff. I am a complete newbie to trunking. Ok, I have a BC780XLT and I want to program in the data for this area: http://www.radioreference.com/modules.php?name=TRSDB&sid=426
Any help on how do go about this would be greatly appreciated. Thank you!
