Also, there are no options which would cause no SSB transmit audio (and seemingly no TX output power because SSB only has power when you talk) only on some bands. There are no menu options for the FT817 which can cause output to be present on VHF/UHF and not on HF/6m. For a working radio, if the antenna is bad or missing you will still see TX power output shown on the power meter bar graph on the FT817 screen but the high SWR icon will show. If there is no TX output only on one mode, then the diagnosis given in this answer does not apply.įor a radio that doesn't have any faults, the kind of antenna you are connected to makes no difference as to whether or not the FT817 will try to output TX power. I'm also assuming that the problem you are seeing occurs on AM, FM and SSB. I would use an external power meter connected to a dummy load to be sure. I'm guessing that you are deciding on whether or not the FT817 is outputting power by looking at the power meter bar graph on the FT817 screen or by looking at an external power meter. If someone has messed with the alignment settings, ignore what follows, because what to do for that is a different answer.

Tim, what you have said provides a few clues to the problem you are seeing.Īssuming that someone has not accessed the hidden menu which allows factory alignment of the radio, your problem is not a config issue.
