The same thing occurs with my Drake R8B.


Mine too. It's my second R8B and the first one also did it. I'm pretty
sure it's caused by high impedance leakage around the pot. I discovered
this when I had the receiver apart for some maintenance. I removed the
connector to the volume pot and I could still hear some weak audio.
Since I use the R8B close to my bed, I installed a mute switch in the
speaker circuit so I don't hear any sound when the volume is down all
the way or up too.


Build a small attenuator pad in line with the headphones.

A few years ago I bought a minty Drake R7A. I sent it to Drake for a complete refurbish and they did a wonderful job. However, I always wondered about the volume output. When the volume knob is turned down all the way I still hear audio coming from my speaker or headphones. Is this typical of these units? It's not a big deal but it does make me wonder. If this is not typical, what can I do to make it work like other rigs.


Mine and a couple other TR7's did the same thing. Never tried to find
why or fix it. Made an "audio" panel of slider pots and ran all
receivers through it. I could set the level for each radio or if the
phone rang, one finger ran all receivers to zero.
