Audio Attenuator

I found the WA8LMF universal sound card audio attenuator works pretty good and created a few PCB’s for it.

Version 2 – I found on a few of my radios the attenuation was a little too much.  So I created a second version replacing the 10K resistors with trimmers.  This version also includes stereo jacks so pre-assembled cables can be used.  A Sacagawea dollar coin tube makes a nice little case for it!  V2 kits are now available in the store.  Instructions and manual can be found here.
