Unlicensed QRM on the 449.525 Repeater

Recently, we’ve been having trouble with unlicensed operators using the output frequency of the 449.525 for simplex communication.

We tend to hear this most heavily in the early mornings, Mon-Sat, but sporadically in the afternoon and early evening as well. None of us who are monitoring this situation speaks Spanish, so we are unaware of what is being said, but we have yet to hear any call sign being transmitted. We have a suspicion of multiple mobile stations, and a base station.

As best we are able, we have transmitted warnings regarding this operation, but we can’t tell whether any of the operators are hearing us.

We are working on some RDF and triangulation. Here are some images showing an estimated bearing. We will update these images, and this post, as we learn more.

We have a report that the signals are very strong in the area of Faversham Park, 73rd and Ingalls. That is possibly the next location for an RDF trip.

If anyone can assist with RDF, speaking Spanish to communicate with these operators, and/or locating a place of business, please contact us. We would greatly appreciate the help. If you’re on QRZ, there is a discussion thread available.

Mt. Evans Ascent Coming up on June 8th

Coming up on June 8th 2019, Intermountain Repeater Group will be providing communication support for the Mt. Evans Ascent foot race, benefitting Alpine Rescue. The race itself starts at 6:30 AM, so amateur operators will need to be leaving the start line prior to that. Please contact KEØSJ — Bob, our club President, if you would like to volunteer to help out. Bob will be sending out information via e-mail to our radio crew as we get closer to the event. Radio amateurs will be operating from the start line, the summit, and at the aid stations along the course, relaying requests for support, race progress, and any other communication traffic as needed.
