[Elecraft] P3 not showing anything

[Don Wilhelm]

Andy,

Do you have another receiver?  If so, connect it to the K3 IF OUT.  If 
you hear signals, then the K3 is working fine, look at the P3 for the 
problem.

OTOH, if you do not hear signals, review the work you have done - was a 
cable left unplugged inside the K3 or other "silly" stuff like that.

The IF takeoff is before the roofing filters, but the BPF3 is before the 
IF takeoff.  Check your work with the KBPF3 installation.
