I got a QYT KT-8900D from a fellow ham and used it to experiment on APRS and TNC nodes, but unfortunately it is very slow switching from RX/TX so it is not great on packet. While not the best of my rigs, it has performed reliably and so far has not had any problems.

This is used/kept as a backup for when I operate portable for public service events. Not much to be said about this one – it is a chinese brand and it happens to just work without issues.
