Next Zoom : Monday, Nov. 9, 2026  7:00 pm MT

Program Topic:  Rig Basics – Understanding audio compression and ALC in SSB communications.  

 

Summary: 

Audio compression and ALC are often misunderstood or overlooked features in modern HF transceivers.  A short review is presented by Jerry, VE6TL, as to the theory behind these circuits and how to set up your SSB audio output to better achieve your goals.  For example, some like to ragchew, which typically requires a broad spectrum of audio frequencies, while others like to chase DX, which tends to favour higher frequencies for more “punch”.  Speech compression can also play role and sometimes make the difference between being heard in a pileup or not – especially if you are limited to low power (< 150 W).  So join the discussion and share your experiences on setting up your rig for compression/ALC on SSB.  

 

Your Questions and Suggestions

As usual, we encourage you (especially newbies) to ask your ham radio related questions to the group and also to suggest topics you’d like to see addressed over the coming months.  If we can’t answer them, we’ll make stuff up – just like some of the AI chat bots I know!  

 

 

Thank you!
