Yes, agree he should have left one. but I was able to find one for another old peice of equipment in my ever expanding pile of old equipment and cables in the basement. AM21 powered right up, set up the local channels (it did ask me for my zip so the earlier posts I read about it scanning for channel vs. the database of OTA channels has me a bit confused) and then it displayed all of the OTA locals in the guide. I went to the one active C41 client TV's and there are the local channels too. Great way to get the local weather channel on multiple TV's without having to have AM21's, built in OTA tuners and OTA cable runs per set.
