Do you have a question about the MR HH425LI VP and is the answer not in the manual?
Questions and answers
None of the NOAA stations are working. I **** in Philadelphia MS
The NOAA stations may not be working on the Cobra Marine MR HH425LI VP in Philadelphia, MS, due to several possible reasons:
1. Signal Coverage: NOAA weather radio coverage depends on the availability of nearby broadcast stations. If there are no NOAA transmitters within range, the radio may not receive a signal.
2. Programming Issue: The radio must be correctly programmed to receive Specific Area Message Encoding (SAME) alerts for the desired location. If the station is not designated as a SAME channel, local alerts may not be received.
3. Interference or Obstructions: Buildings, terrain, or other obstructions may block the NOAA signal, reducing reception quality.
4. Radio Settings: The NOAA Weather Alert mode must be enabled to receive alerts. If it is turned off, the radio will not detect NOAA signals.
5. Antenna or Battery Issues: A loose or improperly installed antenna or a low battery charge could affect reception.
Checking signal availability, ensuring proper programming, adjusting the radio’s location, and verifying power and antenna connections may help resolve the issue.
