Similar setup here. A couple things I’ve discovered.
1-Set a tone for both inputs. It’ll keep randoms from triggering it.
2-Ideally, you use VHF in, and UHF out. You’ll be able to hit the repeater from further out w vhf, and since it’s transmitting from a better location, uhf will typically carry far enough. But if you need the repeater to Tx further, use uhf in, to get vhf out.
Agreed on using tones!
Nice video, If you build another one you might consider using velcro for your charge controller as well. That will help to eliminate more penetrations in the box.
Valid. Since there was weight hanging on it I wanted a physical connection. If I really wanted this thing to be waterproof I'd do thing differently. I made the holes for the screws so small that I actually had to thread them in, so they are tight in the box. Thanks for the email!
Thanks for this video, I just bought a similar TYT and planning a similar repeater build so perfect to get some info from your video.
Greetings from Sweden
Glad it was helpful!
Well, this repeater ready work on GMRS
No, it's a cross band.
My wifes family lives on a self-sustaining generational farm, about 400 acers. There are 5 houses on the farm and everyone works it, and they all run around with their UV-5R's, but there are hills and valleys, so there are dead spots. Im thinking something like this would be perfect for better communication. I'll have to figure out how to set up a repeater, but im sure there is a video on YT for that. But if the repeater is under heavy use, could I just upgrade battery and solar panel size to accommodate? Andbhave you used this set up with great success, meaning no problems with wanting to utilize the repeater, but it isn't functioning properly or there isnt enough power to keep it going? Im really looking for a set it and forget it.
What I would do is buy a retevis GMRS repeater. They run on 12v. Yes, you can just put a larger battery and solar panel on it and set and forget. Feel free to email me directly to discuss
Is it possible to use repeater mode in the same band? Like 467.450 in and 467.550 out?
Not with this product. It is a cross band repeater. But it solves a LOT of issues with duplexers and channel separation. If you want a same band repeater you are going to spend a lot more. Also if your radio is a dual channel baofung it's super easy to set up this way
