K1 Serial 02129
KFL1-4
No output on 20 meters
Works fine on other bands.

It used to work.

I did some signal tracing.
I see signal on pin 1 and 2 of P1 of the filter board for all bands
I signal on pin 2 of T1 on all bands
I see no signal on pin 4 of T1 on 20 meters - good signal on all other 
bands.

What could cause this behavior?
Signal is going through T1 on other bands.
Could there be something drawing down the signal on 20 meters?
I looked for shorts and didnt see any on the filter board.
