KPA500 assembly

[Georgek5kg]

I am assembling my KPA500, and am to the point of installing the RF Power  
Amplifier/Low Pass Filter (PA/LPF) Module.  I notice when handling the  
module, if I gently rock it back and forth, I hear a small clicking sound  from
somewhere in the module..  
 
I have inspected the module, and do not see any debris or spare parts loose
 in the module.  Is the clicking normal and, if so, where is it coming  
from?  If it isn't normal, what next?
 
73, George

Hi George,

This sound is normal and it is most likely coming from the ferrite beads that are mounted on short loops of wire on the RF amplifier PCB.

73,
Eric
