Hotspot Frequencies

From time to time I get asked about the best frequencies for use with Hotspots. I decided to dig into this get some answers.

I started by looking at the information available from my local frequency allocation organization, SCRRBA. I couldn’t find anything listed, so I sent them an email.

They gave me two frequencies, 441.500 and 441.520. These are identified as “Simplex Digital (packet) 16khz BW – no voice”. The “packet” and “no voice” threw me a little.

SCRRBA Freq Allocation

If you have a duplex hotspot you can use one of the test pairs (446.860- and 446.880-). Be aware, there are lots of repeaters in SoCal using these frequencies.

If you are not in Southern California you should check with your local frequency coordination group as this will probably be different for you.

For example, I looked at Arizona and found 441.500 is a repeater control channel. In general they don’t coordinate simplex channels.

    We have the same issue in Nevada they do not coordinate simplex frequencies. Here in Vegas we have an issue with some putting up All Star nodes on simplex but having an antenna on a 50 foot tower. They are using CTCSS so not hearing the others they are causing issues with. One such individual is running so much power it’s causing interference over 15 miles away. He has been reported but nothing gets done. When someone gets on and tries to talk to him he say he doesn’t speak English, but the node Id’s in English.

    What would be the safe place to park our spots?

      What do you mean by “a safe place”? Are you talking about the frequency? If you are in Southern California, the frequencies mentioned in the article are probably the best choices.

      If you are somewhere else, look for a digital simplex frequency in your local band plan.
