Hi FT-847 users,
I have the problem with my FT-847 that with FM the squelch closes a
little, but when turning the knob further to the right, the squelch
opens again. If the squelch knob were a clock face and if there is no
signal on the VHF/UHF band: So if the knob starts at 7 o'clock and the
squelch closes at 8 o'clock, it opens again at about 11 o'clock and then
remains open until the right stop. With SSB everything works fine. I
would venture over with meters, oscilloscope etc if I knew where to
start. Is there a comparator or Schmitt trigger where I can start my
search? Circuit diagram is available.
Thanks for reading!
