Radio Overhaul - Alignment page 2

So here's a good test of the stereo separation the radio has. The Leader is set for L channel only transmission.

OK, so the radio is doing a pretty good job, there is a little on the right side, but it's mostly attenuated.

Checking for stereo balance by just sending the R channel now.

Again pretty good for a 1968 car radio. All this is fine tuned by adjusting the ferrite cores in the stereo decoder and the separation rheostat.

Now to transmit the L & R channel but with the pilot off, meaning no stereo, just monaural.

Stereo lamp off.

Now you can see the same sine wave but it's a smooth sine wave in monaural.

Since I have the Sencore I can use it to double check the Leader.
