Here is a little something to put into your scanner…..These frequencies can be received with any analog conventional scanner. At first glance you may think, how are these frequencies relevant to grid down? Well they are not. But…….the purpose of monitoring them is. All of the frequencies are in FM mode.
- 137.100
- 137.620
- 137.910
- 137.850
- 137.300
With a little open source research you should be able to figure out what they are, some of you may already know. Put them into a utility scanner and let them run. It may take a while to get any hits, but, with patience you should intercept something. If you use an outdoor antenna your success will improve. Give it a try and next post I will reveal the purpose of this exercise. Feel free to post your logs or thoughts.
