Hi, I'm new to all this, and as you can imagine, I have lot's of questions. The first of which is this: How much power do I need to use GMRS over a repeater that is about 16 miles west of my house. I can't seem to hear any signals coming from the repeater, and I don't think my 4 watt handheld would be enough to reach out that far. Am I dreaming thinking I can use my TERA TR-505 handheld radio to communicate with anyone that is in range of the the repeater coverage area? I'm not sure what equipment I will need to get on the NET meeting and participate. I can hear traffic when I tune a different radio to the frequency. I was wondering why I can hear traffic on the one radio but not on the TERA GMRS radio that I just bought. Any tips for a beginner would be greatly appreciated. Thanks!
