- PRO34.8
- After using his Radio ShackO PRO-34 portable scanner for
- a few months, Ron Smithberg, a radio hobbyist in Joliet,
- was hampered by a "wandering birdie." Ron's scanner was
- hearing itself on a few frequencies in the VHF-Hi range,
- but the birdie disappeared when he tilted the radio or
- squeezed the case. There had been no problem when the
- scanner was purchased initially.
-
- I suggested that a ground connection or a circuit board
- in his PRO-34 might be loose. The thin PRO-34 plastic
- case feels chintzy, and can flex easily by applying just
- a gentle squeeze. After prolonged use, the case motion
- can loosen screws which were once tight.
-
- Ron disassembled his PRO-34. He unfastened the helical
- antenna, knobs, and rear screws, then gingerly removed
- the plastic case. After Ron tightened a PhillipsO screw
- holding the Logic Board to the front of the case, the
- birdie disappeared forever!
-
- The operation took a steady hand. Although he didn't
- have to remove any boards, Ron warned that accessing the
- offending screw was a challenge. He used a very small
- Phillips screwdriver, positioned through a hole in a
- shield partition.
