BC760XLT Modifications
Concerning the Uniden Bearcat 760xlt, the mod for the 950xlt does work
to restore lost freq. Disconnect pin 20 of the microprocessor from the
circuit board and connect it to pin 19. I bent the pin slightly and cut
it with the scissors of a swiss army knife then soldered an 1/8 lead
cut from a cap across the pins near the top of the chip.
The following "magical" modification will allow reception of celluar phone
band on a Bearcat 760XLT.
Note:
This modification should be performed by someone very familiar with
electronic componets. This will also void your warranty.
Author assumes no responsibility whatsoever.
Disconnect power cord from wall outlet, remove the four screws
holding the bottom cover on. Remove bottom cover carefully, speaker
wires are attached.
Locate the large 64 pin microprocessor chip near front of the radio.
Noting the indented dot which marks pin one, count along row to pin
20. Cut that pin close to the circuit board so if you ever want you
could tack solder it back together.
Chip in the unit has following numbers:
7D3
HD 40740085
JAPAN
Temporarily reconnect power to the radio and attempt to program 845.000
Mhz., confirming cellur band restoration. Frequencies may be entered in
12.5 Khz, not 30 Khz, increments.
