Well hers the deal: first a link to the kenwood brochure in pdf format showing a model with black buttons, and specifying the wide/narrow capability. Second, I put my TK-860H with black buttons on the bench, and loaded up my programming software, and went in, selected narrowband for all my channels, and wrote it to the radio. Also, a call to my local Kenwood dealer confirms that the TK-840's, 860's, 880's are all narrowband compliant. It has nothing to do with the G model spec. So lesson- don't believe all you read on the internet. Frank KB0YYE
