What Radio8Z said about mis-reading the colors on a resistor happened to me, when I thought I had a 1k resistor in the right place (brown, black, red), yet I was getting strange results.
Then the lucky moment arrived when I noticed my resistor was brown, red, black, which I think is a 12-ohm resistor.
Also, 1580, you said something that needs to be double-checked… you said that changing the RF output power control had no effect on modulation, and the fact is it SHOULD have a very strong effect on modulation.
There is a correct balance that always needs to be set between modulation level and power level.
If you increase the RF power the modulation decreases and needs to be raised.
When the RF power is at minimum the audio modulation must be reduced or it will strongly over-modulate.
Keep working on it. What you learn will pay off as part of your technical education.
