Simple electronic keyer
This circuit in figures 1a and 1b is a simple keyer which can be built
Simple Noise Generator
As a signal source I thought about noise because we knew from school that all frequencies were present
Keyer ETM-5C Elektronik
The electronics should no menus and double occupied
Building A High Voltage
I stumbled on an article by a german ham and materials engineer
Installing long wire antenna
Installing a long wire antenna when the only best way is to attach one end to a tree
