I haven't been able to find any discussions about the Relm HS 200. I guess it is too old. I have two. One I bought when they first came out and one I recently bought. The latest one developed a problem after a few days use. I let the the batteries run down in it. Now it ignores the channels above 100. I performed the clear memory function. It cleared out all of the data but it naow acts like an HS 100. It wil only allow access to 100 channels and the subaudible tone and digital squelch funtion is gone. I think I read something about this several years ago but haven't been able to find anything now. The Relm scanners are great for conventional scanning. Can anyone lead me to a source for advise. Thanks.
