I strongly suggest not transmitting until the receiver is working. Unplug the key or paddle.
On my build I missed on solder connection in the audio section. I found the issue by turning on the alignment source, yes free test equipment already built in. I poked around and found my issue. Also as mentioned its easy to not get the enamel off the toroid connections.
You have enough test equipment,? please slow down and I think you may solve it.
Keep in touch
Curt
