[R-390] R-390 Non-A...have a question

Hi John,

I agree with your assessment of your audio problem.

The oven switch wiring I would look at more closely.  Are the wires soldered together for sure...all three..or two with one not connected but heat shrunk along with the other two.

The reason I ask is because you really don't want the ovens to be used.  Not necessary in our use of the radios and in fact could cause harm to the radio if the temp ran away.  If all three are soldered together the ovens are probably on.

None of what you have described are published mods...or military mods that I am aware of...just sounds like someone has been in there hacking around.

Should not be too difficult to put right.
