    Are there any other commonly used simplex frequencies on 2 meters and 70 centimeters FM other than just the 146.520 and 446.000 national simplex calling frequencies? If so what are they? It seems like there ought to be some sort of agreed upon system of simplex frequencies other than just two, doesn't there?
    Thank you

    well no, not really.

    use the calling frequency to link up with someone, then qsy to another freq. use the bandplans to determine where in the bands you are least-likely to cause interference to other hams.

    446.000 usually does everything that needs to be done; however around here besides 146.52 we commonly use 146.535, 146.550, 146.565 and 146.580 and there's often activity on all of them. However this is a very "regional" thing and in different areas they use other simplex frequencies.

    Depending on the area in which one lives, going in 20 kHz, or 30 kHz, steps above and below 146.520 MHz there is usually quite a bit of simplex activity. In a few cases, 15 kHz steps are used. In Texas, where the 20 kHz steps are recommended, 146.500 MHz, 146.540 MHz, and 146.560 MHz are common simplex frequencies besides 146.520 MHz.

    For 446.000 MHz, steps either 25 kHz, or 50 kHz, are common for simplex operation.

    Of course, this is for FM / PM operation.

    144.200 is pretty popular for SSB

    Just scan in 5khz steps between 146.400 and 146.600 until you find where the local action is. In 20 years, I have never heard a simplex qso on 70cm, outside of VHF/UHF contests. Could just be my area, though (pretty pathetic considering there are about 5 million people in my grid square).

    Usually try calling on a repeater freq....simplex's aren't easy to listen in a far away distance (i like being qrv simplex).
