    TYT TH-UV8000D available from amazon, us$ 70.00

    "cross band repeater function". is that the same as "full duplex"?

    thanks!

    Unusual phrase.Based on the price probably not full duplex.

    Not really. The cross band repeater function allows the radio to act as a repeater.

    Agreed. The manual lists it as "semi-duplex".

    There are a number of videos up on YouTube. Here's one from Dave Casler:

    It shows the radio operating as a repeater, but only using signal input from another radio. I haven't found any videos using the UV8000 as a "signal source". The cross band demo starts at about 30:15.

    I need another HT like I need a hole in the head, but for $69 I'm tempted...

    I've got MFJ-916BN for SAT. They're similar to mentioned above MFJ-916B except they're equipped with good N instead of not desirable UHF connectors. I never measured them with a network analyzer however they seem work flawlessly.

    In terms of hardware yes. In fact I saw a Chinese HT (can't remember model) that has crossband repeater but has NO crossband duplex. Obviously it is firmware flaw that indeed cannot be fixed by user so useless for SAT.
