We have some of the TP9900 radios at work, I am pretty impressed overall, multimode & multiband is great.
Most of the options are enabled on our test radios too, except for encryption (not even basic digital encryption is enabled, odd..)
So far have just been testing these in DMR & P25 conventional modes.
Yes it is a slight annoyance that you cannot have DMR & P25 channels in the same zone.
Also, if using these radios to just RX scan P25 trunking systems using the P25 conventional mode, it appears you are not able to program the radio to selectively RX individual talkgroups. I have tried various settings, and it if set to Selective under the Basic P25 Settings page, the radio appears to just RX the TG listed in the Talkgroup column on the Channel page. Selecting another TG via the Menu has no affect on this behavior. I am guessing this will only work correctly when the radio is set up for P25 Trunking mode, which I cannot do of course without a system key. Anyway, the audio sounds very good, and is nice to have a commercial portable to play with that covers the 2m & 70cm bands !
Pity I could never afford to buy one for personal use.....
