firedrake jammer logs

To participate in Firedrake monitoring again, I loaded my Eton E5 with six memory pages worth of recent Firedrake frequencies. With seven frequencies per page, but only four frequencies on the last page, that's 39 shortwave frequencies. I suppose I've created something of a hitchhiker's guide to firedrake monitoring on my radio. In spite of this setup, band scans are really more helpful in locating the broadcasts, as jammers are moving targets.

Finding Firedrake on shortwave has been difficult for me. Most of the recently reported frequencies from Glenn Hauser's DX Listening Digest have been daytime frequencies, and most of my shortwave listening is at night. I'm in California, so I'm in an advantageous geographic location for receiving Firedrake if it's broadcasting.

Early morning monitoring has worked the best for me so far, although I don't get a lot of opportunities. Here are some of my firedrake receptions, all with the Eton E5 receiver and the Degen DE31 active loop antenna.
