I have an ICOM IC-R7100 receiver/scanner that has a problem. I can
receive nothing below 250 mhz. There is no hiss or noise, just like if the
squelch was fully turned up, and it is not. It works fine from 250 mhz+ to
762 mhz where it sometimes cuts out as described above. Any idea of what is
wrong with it??? Does anyone have a schematic or repair handbook for this
radio? Thanks for the help.
