How’s That North America Adventure Frequency Working?

In January 2021, I wrote about the North America Adventure Frequency (NAAF) which originated in the North America SOTA community. About a year later, how is this working out? Is anyone actually using it?



A few key points to remember:

  • The NAAF is 146.58 MHz.
  • This frequency is in addition to, not a replacement for, the National Simplex Calling Frequency 146.52 MHz.
  • Local usage will likely vary depending on needs.
  • Program 146.58 MHz as The Other Simplex Frequency in your radio.

I’ve noticed that quite a few SOTA activators are posting Alerts and Spots with 146.58 MHz. For example, K2CZH and KN6OUU posted these SOTA Alerts:

Here N8FN and WJ7WJ are spotted on 146.58:

Of course, the National 2m FM Calling Frequency (146.52 MHz) still gets a lot of use. I tend to use Five Two when I am activating in rural areas, some distance from the major cities. The frequency is usually quiet AND there are a number of folks that tend to monitor it. I use the NAAF when I’m near the big cities (Denver, Colorado Springs, Boulder, …). Putting out a Spot is usually important, to get the attention of the more dedicated SOTA chasers watching SOTAwatch. That is, I don’t think there are a lot of people monitoring the frequency (compared to 146.52), so a spot on SOTAwatch gets them on frequency.

Some of the Parks On The Air (POTA) activators are also using NAAF. Here’s an activation alert by KD7DTS from the POTA website:

So I think the NAAF is working as intended. It is not a replacement for 146.52 MHz but a standard choice for portable operating when you want to stay off the calling frequency. Thanks to everyone that has given it a try.

    Interesting, I need to dust off my IC-25A and put it back in the truck and see who is on 58.
