Driving a Telegraph Sounder from HF Audio

 

Someone commented today on a Facebook group about using a sounder with modern HF gear.  It reminded me that I haven’t posted about this or uploaded some files related to the topic.  I’ve used a sounder on and off with HF gear for years.  There are a couple of schematics out there, one on the W1TP museum website, the other on the Morse Telegraph Club website.  I took these designs and added some enhancements, then re-rendered the schematic.

It’s a simple circuit with parts easily obtained.  I ended up making another driver for someone and wrote up some instructions for its use.

There’s nothing like completing a QSO entirely by sounder!
