anyone ever use a Zastone D9000 and duplexer as a gmrs repeater?

Someone asked me if I had ever heard of anyone using a Zastone D9000 with a small duplexer as a gmrs repeater, thought this may be a good place to find out.

Well for starters its a ham radio and not legal on GMRS.

Thats what I told him, I had never heard of that brand of radio so thought I would check

Yes, this radio isn't part 95 with FCC. Still, if I were in an emergency situation and wanted to park my truck on a hill in the desert so that we could search for a missing kid or something and use our GMRS radios to communicate, I'd like to be able to do that. I have a duplexer that I used for a GMRS repeater previously.

I tried setting it up but I couldn't get it to work. The demo video has a different offset and it looks like it will only in-band repeat on a specific set of frequencies. I'd love to know if it could work on GMRS. There was a repeater listed on this site for my area a year ago that said it was using this radio. One reason I bought it was so I could use it for a temporary GMRS repeater in an emergency. Sad Face. Still an OK radio for an amateur, which I am also licensed for.

Hypothetically, but the internal duplexer has a 10 MHz split centered on 442 MHz.

You'd have to connect an external "flatpack" duplexer, but at that point…  Yeah, you've kitbashed together a cheap effective duplexer for around $300.  It should outperform the RT97L, frankly -- at least if you use the right kind of duplexer, but they're increasingly cheap and ubiquitous.
