Fred,
Your problem is not really a problem. The cause is the 8 volt regulator
which is on the low side of its 10% tolerance range. Just set the AGC
threshold pot to maximum and all will be well.
If you want to optimize the AGC threshold later, you may do that, but
wait until you have the K2 complete and functioning.
