Thanks Mike, I was trying to connect to Digital Fusion repeaters but DMR I know nothing about. Antenna is on top of my chimney, I have no building shielding with a good line of sight...open fields to my north and north-east. Using rg8x power at 25 watts. I live at FM 1093 and FM 723 ....Westheimer Lakes subdivision. Thought I had good reception with initial connection (new just got radio 4 days ago) but had totally no connection on 444.000 from Friday through to Sunday night at 10pm which worried me. Thought it was my FTM100dr so I kept resetting it to factory default settings all weekend. It finally it connected for me Sunday at 10pm. That's why I thought it might be my antenna. Please advise. Thank you for your help.
