10 meter calling frequency

The 2m FM voice calling frequency is 145.500MHz and the 70cm FM voice calling frequency is 433.500MHz. Here’s how to use them: Adjust your radio’s squelch, to be able to hear weak signals (just on the edge between silence and the white noise ‘hiss’

The 2M SSB calling frequency is 144.200 MHz , so that is the first place to look for activity or to call CQ. One of the realities of 2m SSB operation is that many times, no one is on the air.

The conventional wisdom in amateur radio is that we should not call CQ when using FM on the VHF and UHF bands , especially on repeaters. The reasoning for this is that during normal VHF/UHF FM operating, radio amateurs are tuned to a specific frequency and will easily hear a call on FM.
