    Default NOAA Weather Radio Band Scan - Easton, PA

    Here are the results from Easton, Pennsylvania, Northampton County near the Delaware & Lehigh rivers.

    Midland Weather Radio, model 74-109 with it's 23 inch, 7 element telescopic monopole antenna in a vertical
    polarization next to a second level window that faces north.

    Modulation is Narrowband FM.

    1. 162.400 MHz - WXL39, Allentown, PA, 1kW ERP, Strong signal
    2. 162.425 MHz - WXL39 adjacent channel interference
    3. 162.450 MHz - WXL39 adjacent channel interference
    4. 162.475 MHz - Clear/Open
    5. 162.500 MHz - Clear/Open
    6. 162.525 MHz - Clear/Open
    7. 162.550 MHz - Clear/Open

    Starting today I will be monitoring both VHF-Low & High NOAA frequencies for tropo and Es.

    You have near-ideal conditions with only one local, and on the lowest channel at that. (Only messes with one adjacent frequency, not two.) When I get my first SDR next week I plan to join you.

    Good luck. Maybe we'll have some hi-band e-skip this summer and can log each others locals.

    Ryan:

    I will look forward to your Fort Myers WXK83 on 162.475 MHz this summer
    at 1,043 miles distance.

    If you have a station on 162.400 MHz on the SDR, what is the signal
    strength level?
    1. Faint
    2. Very weak
    3. Weak
    4. Fair
    5. Fairly good
    6. Good
    7. Moderately strong
    8. Strong
    9. Very strong

    That would be wild if we both get warnings for severe thunderstorms with
    a tornado during the same hour.

    162.4 would be a 5 with the dipole pointed at it. There's also 162.525 in Naples which gets a 2. Severe thunderstorms are pretty common here in the summer, but not tornadoes.

    Unfortunately the band fills up for me under fairly weak tropo. The best antenna I have to use is an old pair of rabbit ears (the TV and FM antennas perform poorly), but I think I need something more directional or WX will be just as frustrating as the FM band. I'm thinking of building my own yagi.

    Just keep in mind that NOAA WX stations use vertical antenna polarization. That is probably why your horizontal polarized TV/FM antennas
    used for the WX band seem to perform poorly. Since you already have rabbit ears, place them in a vertical configuration as high as possible
    in height outdoors.
