900 XTS2500 FPP in 902/927

[N4KVE]

What's the deal with this? Many people claim while the 900 XTS2500 will do FPP in the commercial band, they will not in the 902/927 ham band. That's exactly how my radio works. But I have seen film clips on You Tube where a 900 XTS 2500 does it perfectly in the ham band. A fellow from California offered to "fix" my radio to allow it to work, but I don't care to send my radio across the country to a total stranger. My radio has current FW, & a FC of 500098-00148C-6. It had a FPP FC, but since it didn't work at 902/927, I took it out. Is there a special FC that allows FPP in the ham band to work? What's the secret here? There's several of us who would like this feature in our radios.

Success!! My friend figured out a way to get the FPP option to work in the 902/927 band. No Depot tools or anything. Since he figured out how to get the FPP to work on a XPR6550, I knew he could do this. Took him about an hour. Similar to getting a 450-512 radio to work in the ham band. Now FPP works everywhere, ham & commercial.

May I inquire as to how he did it? I would like to use an XTS2500 on the ham band.

Any XTS2500 can easily be hex edited to work the 902/927 ham band. The problem is getting a FPP flash code in your radio, & then getting FPP to work in the ham band vs only working in the commercial band. My friend is not quite there yet. While it was FPP in the ham portion, the first time I wrote something with my laptop, FPP in the ham band went away, but it still works in the commercial band. He's still working on a fix for that. The FPP flash code we are using is 520001-001104-9, so the first step would be to install that flash code in your 900 XTS2500 radio.
