You should hear relay clicks because they are switching trimming
capacitors in and out when you switch between 10m and 12m. Out of
curiosity, could it be a faulty relay somewhere in the band pass
filter area? If it cannot connect both trimming capacitors to the
filter when you switch to 12m it might explain why you cannot peak BP
filter on proper frequency and it would cause output power to be low
while still having internal RF voltages high.
