Cobra MODEL(s): 150GTL, 200GTL
DESCRIPTION: After adjusting the squelch control, sometimes received signals may sound
choppy due to the squelch repeatedly opening and closing.
ACTION: Change R47 to a 2.2 meg-ohm resistor. This will increase the squelch hystersis.
See images for the location of R47.
- 1. Turn the squelch control fully clockwise.
- 2. Inject a 1500uV signal to the antenna connector (1KHz, 30% modulation).
- 3. Adjust RV2 until the squelch just opens.
