I am very new to GMRS. I received my FCC license (want to be compliant) and purchased a Wouxun KG-UVDP1 mobile handheld unit. The range is OK for a handheld and quality seems good. I like the ability to program several channels as well as the manual mode to dial in frequencies.
Unfortunately, I live in a rural area and the nearest repeater is approximately 30 miles away. I am in Florida so the terrain is rather flat, but the foliage is heavy. Obstructions are definitely an issue here and I know there is no way I can link up with that repeater from my home (not in a million years with my handset).
I want to build a repeater station of my own. I don't want to spend an arm and a leg on it, but I would like it to work fairly well. I am fairly good with electronics/computers and have a very basic understanding of RF properties. I don't mind buying a part here and a part there, but would like something I can operate inside my house (I understand the antenna will be outside). I would like to utilize the full 50W allowance I have under my license in order to maximize broadcast range. Again, I am in a rural area. I know this will not help me if someone is not capable of transmitting back.
I have been looking at the GR300, GM300 Radius in repeater configuration, and the M120 in repeater configuration. One concern I have is the availability of replacement parts and future proofing. Since these units are no longer sold I am worried about "future proofing". I understand things change, products enter and leave the market, but should something break I would like replacement parts to be available.
Ultimately I am looking to those of you who are more experienced than I. Can you recommend a path to take with this and/or equipment to use. I know there have been recommendations in other topics on this forum, but none of those scenarios matched mine. Hoping to get some good information!
Thanks in advance!
