[Sinewave]

I made a little mistake, for some reason I touched RV101, which moved the ALC to about 100V. It wasn't until I was checking the ALC circuit that I thought something isn't right. So I've set RV101 back to where it should be, by the previous waveforms taken and measured the voltage at V102 to make sure it's back to 48V on pin three.

Now, the one I should have touched, RV103. Fully CCW, voltage at the resistor junction is 4V pk-pk with Set Carrier CCW and 1.03V when fully clock wise - and this time the waveforms/output remain!

RF output level at 5.87V RMS and 1.47V RMS respectively (EMF).

And when the RF stage wakes up shortly after power up, that 'peak' has gone away.

Now, things are much better.

But I'm still too chicken to fit the thermocouple, despite all measurements taken suggest that it's likely to be absolutely fine to fit the TC.
