MOD1464#2: doubling tank circuit capacitor 1nF to 2 nF reduces frequency from 5647 to 5471 at phase shift 0

until proven otherwise

What are the values of R12, R13 and C10 now ?

You could consider increasing C10 for a longer time constant. I don't like the regulation spike changes C10 voltage so much. if 10nF try 47nF.

R12 = 0 Ohm, R13 = 10k, C10 =10 nF

There we have a troublemaker R12 = 0 ohm, that is no good.

I expected it to be 390kohm as shown in diagram Test 0.1.

Correct to R12=100kohm, that should stabilize a lot.

Luckily we had the 10K R13 between C10 and U4 pin 13.

SUG1471#1: for determination of lock in state an XOR gate for U4 pin1 and pin2 might help

MOD 1473#1 connect U4 pin 2 to U7 pin 1 (as in SM 0.5)
MOD 1473#2 move R15 from U7 pin 11 to U8 pin 4 (as in SM 0.5)

Now D6 should be on when locked.

Here you see why I did not like the switchover circuit.

Now you have to put the resistor correctly at C11 correctly

MOD 1475#1 Break connection between new resistor and C11
MOD 1475#2 connect the new resistor so it is the only signal way from R14 to U8 pin 5,6
MOD 1475#3 connect C11 to the right side of R14

Now U8B is protected against C11, and maybe even the spikes disappear on D6, lets see.

MOD 1477#1 Replace C10 with a 100nF capacitor
