I have a working TX.
Great! That's a good start.
Now C1 maximises in a reasonable position. But I have a lot of noise and next to no signal. The noise reacts strongly to tapping on the board.
Andre,
The calibration signal is applied to the antenna input from IC3 by way of R43. If it calibrates you should receive something. Maybe a bad joint on T1?
when I tune to a frequency (RX only!), then my nearby other receiver responds with a strong continous tone (around 650 Hz) on that very frequency.
This is to be expected, it is a direct conversion receiver, the local oscillator will appear to be strong on a local receiver.
