I have owned my FT-817ND for a few months now and notice that the
receiver has distortion on all modes (CW, SSB, AM etc). Turning off
the rx amp and attenuator helps reduce this but does not eliminate
it. Appear to be an RF issue but maybe audio as well. Are there mods
to fix this issue? Most likely this portable radio does not like full
size antennas such as dipoles and delta loops that I have been using.
