Now and then I need some special functionality. In most cases I have implemented it using a Raspberry Pi Zero. It doesn't have the highest performance but for non-number crunching features it is great. Some of them are documented on these pages.

The rig I use has two different RF connectors. One is for frequencies above 70 MHz and one is for frequencies below 70 MHz. As I use different antenna for short-wave I need an antenna switch. I found one which is a one to four port switch,  SSB-electronic AS-304N.

I use some very good SW for my Amateur Radio activities. All of them are open source. For some of them I have implemented some specific solutions and or configurations.

Currently I have the following pages that describes my solutions.

Airscout

Airscout is a program that is used for predicting Airplain reflexions. I am running it in a container which is somewhat specific...

To be updated!

There are some problems that arrise when running a narrow band mode as FT8 with a bandwidth of 50 Hz with a wider filter, like a normal SSB filter, with a bandwidth of 2500 Hz. The exact behaviour depends on the design of your rig. For me it is an IC-7100.

My setup

Below is a brief description of how I have setup my rig control. Most of it is based on OH1KH excellent description but with a few addons.
