[R-390] Still wondering about the 100mV detector test

[Barry]

Yesterday, I tried something a bit different.  I disconnected the input of
the IF deck and fed it with the output of the signal generator.  I set the
line meter to -10 and the line gain to 10.  With the scope on pin 7 of V506,
I increased the input signal until the the line meter read -10.  At this
point, I was seeing 0.8V p-p (approximately 0.28V RMS).

Apparently, this is nearly 3 times the signal on the detector it takes to
get the output level where it should be.  I'm still wondering if this radio
has a problem.  Anyone else try anything like this (or the original 100mV
test on pin 7 of the detector)?
