PRO-34 Scanner Modification
In regard to the information presented (March Issue) on the
handheld Radio Shack PRO-34 scanner, my own observations on the
modifications have been:
1. To restore missing 800 MHz frequencies, remove D-11.
2. To add 66 to 88 MHz (European Coverage), install a diode at
D-9.
3. D-10 must remain in place for full 800 MHz coverage.
4. If a diode is added at D-13 it cuts out aero band, also seems
to affect 800 MHz channel spacing.
5. D-12 added dosen't seem to have any affect.
6. Only D-10 and D-11 are factory installed.
