I was under the impression that the BPF scan uses the same signal source that does the LPF scan (I could be wrong)
At least the same source but a very different way (see
QMX Terminal Hardware Sweeps ).

Thank you, Ludwig, for the pointer to that description which I had not seen before.? It does confirm that the troubleshooting guidance I gave in my last post is correct: if the BPF scan gives proper results, then the LPF must be at least mostly working.? The main fault would need to be in the PA (via L502 & T501), or in the SWR detection/output (via T507 and surrounding components).
