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.

[@texasprepperprojects]

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!

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.

[@texasprepperprojects]

Agreed on using tones!

Well, this repeater ready work on GMRS

[@texasprepperprojects]

No, it's a cross band.

[@benpoulin5637]

Is it possible to use repeater mode in the same band? Like 467.450 in and 467.550 out?

[@texasprepperprojects]

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
