    I don't own a TH-D74 and one of the main features I need is the possibility of compensating the Doppler shift using Gpredict. Since I haven't found too much information yet, I don't want to risk buying it yet. So it would be very helpful if anybody here has tried or has the possibility to test it. Thank you!

    I was told that the TH-D74A has been upgraded and now does cross band full duplex? True?

    False.

    The TH-D74 still isn't capable of full-duplex operation, not even with the latest firmware.

    No, it's not full-duplex. I bought it a couple of months ago and been using it as RX coupled with an FT-817 for TX to have full-duplex. It works flawlessly (also Gpredict via Bluetooth).

    Thanks all for the prompt replies! Reinforces my belief of trust, but verify!

    Bad news...

    On 24 December, Kenwood announced that the TH-D74 would be discontinued. From Kenwood's web site, translated from Japanese...

    Even though the TH-D74 isn't capable of full-duplex operation, many satellite operators have them. This is not good, especially with Kenwood recently ending production of the TH-D72.

    Ugh that’s terrible news, both higher end Kenwood HT’s gone. With the increased interest in satellites it would be a real loss if a replacement is not on the horizon.

    Not just higher-end HTs, but Kenwood's only multi-band HTs. This is a gap in their amateur product line, small as it is already.

    I haven't heard if Kenwood has a replacement multi-band HT in the works. I haven't seen anything new from Kenwood in the FCC equipment authorization database that would look like one. For now, I have a TH-D7, TH-D72, and TH-D74 here at home - and I'm holding onto them...

    73!
