ICR7000.3
Long live tinkering!
Jack Albert, WA9FVP, reports that he tried a modification,
and it works! Jack doesn't have the remote control option
in his R7000, so he elected to use the front panel REMOTE
switch as a bank switch.
He installed a 48,000 ohm resistor between IC8 pin 19 and
ground, and ran a wire from the REMOTE switch to pin 19.
When you switch between banks, you must also rotate the
channel selector knob, forcing to the microprocessor to read
from memory.
A word of warning:
If the remote switch is used to directly select the new bank,
you will be placing 13.8V on pin 19 of IC8, which is too high.
Instead, make a voltage divider by putting a 68k resistor between
the output of the remote switch and pin 19, and a 39k resistor
between pin 19 and ground.
