Frequency Guide to Air Show Monitoring
By Larry Van Horn N5FPW

Milcom specialist and aeronautical radio author, Larry Van Horn N5FPW, gives us all the frequencies we’ll need to monitor air shows this season. He writes, “With a radio scanner in hand, you will experience a whole new perspective of the show that few attendees will get to experience—radio communications from the aircraft cockpit of the show performers.” Even if you don’t go to an air show this season, you can use these frequencies to monitor what’s happening in the air all around where you live.

TSM’s Amateur Radio Astronomy columnist goes near-space as he shows us how to monitor Automatic Dependent Surveillance-Broadcast (ADS-B) transmissions from aircraft flying over your house within a 200-mile radius using a dedicated Raspberry Pi computer and an ADS-B antenna.

Amateur radio below 9kHz

Until a few years ago, the conventional wisdom was that you needed huge power and huge antennas to be copied “beyond the garden fence” at VLF and ULF. In recent years much has changed and time and again great distances have been covered by amateurs with quite low power and modest antennas.

The trick is great stability, very narrow bandwidths and long integration times, often of days. For several years just detecting a carrier was enough, but in recent times people have been sending simple messages using EbNaut software.

When at the old QTH I detected signals from several European countries using simple, homemade gear and free software.

Although not totally up to date at all times, I try to update news of amateur VLF and ULF experiments at https://sites.google.com/site/sub9khz/ .

18 QSOs during Ski Outing

Judy and I went cross-country skiing down at the Pemigewasset River near Profile Falls. I brought the KX3 and made 18 QSOs (in the CWT sprint) including France, Italy and Germany. It was a bit over 50F.

What a fantastic day to be out. We went east from the road about a half a mile toward the river. Here it opens up into a large field. At the far edge are some picnic tables and the river.

I tossed my 30 foot wire over a pine branch and pulled the wire up over the picnic table. In the sun, it must have been over 70F, because I took off my coat and gloves and I was still hot.

I started out on 20 meters. The CWT sprint had been running for a half hour. Except for the sprint, the band seemed dead. I had no trouble making contacts. After making a dozen contacts on 20 meters, I switched to 40 meters and made another six. Here’s my log. I’ve changed the format to reflect a more normal log rather than using the CWT exchange format.
