Many thanks to SWLing Post contributor, Marc Thomas, who shares a link to this site which describes modifications to eliminate the Tivdio V-115’s internal noise.
In a nutshell, the author made two small mods:
- Decouple the power/battery with an electrolytic capacitor of around 10uF soldered to the battery connector inside the radio (see photo above)
- The author also grounded the speaker, but didn’t test to see if this alone had any positive impact
I could not find contact details for the author of this mod, so I hope they don’t mind the fact I shared it here on the SWLing Post.
Note that the Tivdio V-115 is also known as the Audiomax SRW-710S and Kaimeda SRW-710S (and likely rebadged as a number of other models).
