These little rigs from Yaesu have basically remained unchanged since 2000. They cover all bands from 160m-70cm (not 4m or 1.25m), all modes, 5W. With transverters, mine have been used from VLF upwards on all available bands. They work well, but I was surprised Yaesu did not do an upgrade in time for the last sunspot peak. Also, I was surprised they had no real competitors. These days there are a few SDR radios around, but the FT817 reigns supreme.
With mine I have worked the world including some great handheld DX. For base station use I recommend the Z817 auto-ATU.
I tried the Elecraft auto ATU but prefer the Z817. I am very happy with the FT817, although the early ones had PA failures with low voltage. This was fixed (I think) in the FT817ND.
