Thought I would ask the group for ideas on these issues with a new to me FT-857.? The input voltage displayed on the screen wanders up and down between 12.5 V and 14.4 V.? The actual measured voltage is 14.1 V from the power supply measured inside the radio.? I have a FT-897D and it shows 14.1 V solid.? Also measured voltage sampled at the A to D going into the microprocessor and it is rock solid, no wandering at all.
Secondly there seems to be a lot of noise in the receiver with button presses (no antenna) or when enabling CAT, remote mike control (I have the MH59 mic).? The thash/tones heard in the audio change frequency when for instance the front panel lock button is selected or deselected and while pressed.? My 897D does not exhibit this issue.?
Are these just related to the older 857 or is there an issue.
Best Regards,
Roger (N3EN)
