[Elecraft] KX-1 becomes Deaf when the 30m module is added

[Alexandra Carter]

I just built a KX-1 and it works FB, I installed the 30-meter module 
today and when I went to test it, there are no peaks on 40, 30, or 20m, 
and the rig recieves no signals at all. Pin 15 on the CPU which goes to 
+5V to turn the 30m module on, stays at 0V. I finally removed the 30m 
module and now the KX1 works fine again, re-aligned it on 40 and 20 and 
it's back to its excellent self. I checked the diodes on the 30m module 
and they seem ok, forward drop is the standard .62V you get with Si 
diodes, anyone have any ideas? Are there any of those wires that go 
from the 30m module to the main board that are easy to mix up?  Thanks
