It is interesting that note the LT-590 and TH-9000(d) UHF versions are not available on Amazon and it is unknown if they will become available. OTOH, There is a Retevis RT-9000D That appears to be almost identical to the TH-9000d and is in-stock. I mention the availability of the two Bond Telecom brands (Luiton and TYT) because it may hint at an upcoming change in the MXT400. In fact, the Retevis version may represent close-out stock that they purchased from Bond Telecom. Also, FWIW, the Retivis-9000D programming software appears to be the same as the LT-590. Also, just wondering if anyone here has tried to program their MXT400? I am sure there are a lot of interested people waiting to hear.
