As the owner of two 7Ks, The radio is very good. I have owned both for more than three years. The mobile moves between two vehicles and the base is my primary radio. A tuner is pretty much a must. The radio will shut down power to mis-matches and I suppose eventually die. I do not like the fact that the boxes run pretty warm even just receiving. I mounted a small fan recycled from an old video board to the top air intake of the base. I wired it to the back plane and comes on when the transceiver comes on. That has helped the radio stay much cooler. It is not a radio that is designed to run full power digital modes. That would get it very hot and probably assist the smoke migration. I am very close to WAS and DXCC at 5W on digital modes though.
Many of the older hams that don't understand digital signal processing have panned the radio for poor audio, front-end overload etc. It takes a bit more setup time and tweaking to get your mode tuned than the old radios with two crystal filters and a roofing filter.
When I am in the chat rooms with other HF ute listeners, I am pulling out as much or more than many with dedicated receivers costing many times what the 7K does. Again, antenna and location will make much of the difference.
Bottom line, if you are looking for a primary contest / RTTY transmitter, save your Benjamins. If you are looking for a good priced mobile / station transceiver for light rag chew / QRP digi mode use, I would buy another if I needed it.
YMMV
